Foreword by the Head of School It is a pleasure to write my first introduction, as Head of School, for the 2012 Annual Report. The School continues to perform at a high level with demonstrated excellence in both research and teaching. This report catalogues, in detail, these achievements. In particular, it is noteworthy and pleasing to see the large number of prestigious awards and prizes won by staff and students in the School. My predecessor, Professor Mark Hoffman, stepped down as Head of School in December 2012 to take up a position as UNSW’s Pro Vice-Chancellor for Research. We wish Mark well in his new position and congratulate him on this well deserved promotion. However, Mark will continue to have strong ties to the school and will continue as a much valued staff member through the supervision of research students and the provision of undergraduate teaching. Student numbers, both undergraduate and postgraduate, have continued to grow steadily. There are now over 400 students enrolled in different programs. The growth in numbers has allowed the School to now offer a range of different programs to suit the interests and backgrounds of a diverse range of students, including a high fraction from overseas. Moreover, the quality of students continues to grow. 2012 will be regarded as a year of achievement and success. In particular the School was highly successful in garnering research funds through a variety of sources, but especially through various Australian Research Council schemes. The School was awarded 7 ARC Linkage grants worth $2.26M, representing ~40% of the total grants across the entire university. Several years of outstanding performance by the School are now leading to global recognition. In the latest QS World University Rankings the School was ranked as the number 1 Materials School in Australia and 25th in the World. Similarly, in the most recent round of ‘Excellence in Research for Australia’ assessments the School received a ranking of 5 “well above world standard” in resources and extractive metallurgy and a ranking of 4 “above world standard” in materials engineering. As detailed elsewhere in this report the new Materials Science and Engineering Building is now under construction. Over the past year much work has been done in finalising the design of laboratories and teaching spaces. These new research and learning facilities will provide the school with long overdue improved spaces to work and grow. Funding

International Engagement
The School continues to be actively engaged with the global materials science and engineering community. Engagement, which is of strategic importance and does much to enrich the life of the school, occurs in a diverse number of ways. Around 30% of the School’s undergraduate enrolments derive from overseas. This cohort of students stems from many different countries, but principally from Eastern Asia. It includes students who come to UNSW through joint degree programs with, for example, Tunghai University in Taiwan. In this instance, students perform the first two years of the their program in Taiwan and then Years 3 and 4 here at UNSW. In addition, a large number of study-abroad students come to UNSW to study Materials Science and Engineering. These students come from Europe and the Americas as well as Asia. Further, almost all of the enrolments in the School’s coursework Masters program are international. The School’s international postgraduate research student program has also grown strongly in recent years. Over 60% of the current group of postgraduate students is from overseas. This significant increase in international students derives, in part, from growth in the number of scholarships available to these students. Almost all academic staff in the school enjoy strong collaborations with research colleagues overseas. These collaborations are frequently dynamic and lead to joint high quality publications and grants. Many involve leading institutions such as the University of Oxford, University of California, Berkley, Shanghai Jao Tong University and Nanyang Technological University in Singapore. Staff in the School also collaborate with international industrial partners such as POSCO, Tata Steel and Baosteel. Baosteel, in particular, funds a number of large research projects through the Baosteel-Australia Joint Research and Development Centre, a joint venture between Baosteel and several Australian universities including UNSW. The School welcomes many visitors to study and work here. Some visitors are brought to UNSW by specific funding programs. For example, each year several students from two US universities, Harvey Mudd College and the University of Florida, come to UNSW through National Science Foundation funding to perform research. This diverse range of global collaborations and interactions demonstrate the high standing in which the School is regarded internationally. Plans for the future include the development of more joint degree programs, in particular with leading institutions in China and Taiwan.

New Building Report In 2012 and 2013 the planning and construction phases of the new Materials Science and Engineering building advanced considerably. The project architects, Grimshaw Partners, generated advanced detailed designs through a number of workshops and consultations. This design process also included substantial input from HDR, who were contracted to facilitate the design of laboratory spaces. Several planning meetings were held between the architects, HDR and stakeholders from the School to prosecute detailed designs for the parts of the building dedicated to experimental research and teaching. There was further consultation with staff and students across the school to facilitate design of office areas and other shared spaces. The new building is long overdue and will do much to ameliorate the chronic overcrowding that has plagued the school for the past several years. The significant increase in quality office areas for staff and postgraduate students will be a welcome relief from the current congestion.
Artists impression of the new building interior
Whilst Materials Science and Engineering will be the major stakeholder in the building, the Mark Wainwright Analytical Centre will occupy space in the basement. An Innovation Centre will be located on the ground floor. The top three floors of the building will be retained as ‘shell space’, to be fitted out at a later stage to house specific research groups from other parts of the university that require high quality laboratory space. A key feature of the building design is the flexibility of modular spaces that will allow laboratories to be adapted to changing research paradigms. There are also several open, and highly flexible, areas located throughout the building to serve as, for example, collaborative spaces for teaching and learning, exhibition space for students to present their research findings or areas for networking during research conferences or similar forays. The University Council granted final approval for the $143M project in March 2013. Brookfield Multiplex won the contract to construct the building and work commenced in July 2013. Completion is expected in early 2015, with occupancy of the building scheduled to follow shortly thereafter.

Financial Report Income The School receives its income from three primary sources: Operating income is allocations from the University, via the Faculty, to fund the day to day running of the School. Income, as it is earned by the University, is linked to a series of drivers around the level of undergraduate teaching load and research training, grants and outputs. It is then allocated based upon undergraduate and postgraduate teaching load. Research income is from research grants obtained from bodies outside the university and Strategic allocations made by the University to the School for specific purposes. The graph below shows trends in the School’s operating and research income. $11,000,000 $11,000,000 $10,000,000

Operating income is primarily used for salaries for teaching and research academics and technical and professional staff. Even though a number of the School’s academic staff hold externally-funded research fellowships there is invariably a shortfall in these fellowships which the School pays from its operating budget allocation, following a specific, capped, allocation from the University for this purpose. It is also used to pay for casual teaching, administrative and laboratory staff. Other major expenditure items are support of teaching laboratories, administration, marketing, undergraduate recruitment scholarships and allocations to staff based upon research supervision and publications. The table below shows the breakdown of School operating income in 2012. Total operating income was $4.66m. This represented a modest rise on the previous year, due to an increase in operating income in 2012, that can be attributable to strongly growing undergraduate student numbers. , INCOME University: Teaching

Expenditure The main component of School expenditure is staff salaries which comprises 80% of total non-capital operating expenditure. This is consistent with a gradual downward trend over the last 5 years. Despite the strong rise in salary costs, School income has grown at a faster rate, providing greater flexibility in strategic directions. The table below shows the School’s main expenditure items in 2012. Faculty Research Grants are funds for small research projects which are allocated from the School’s operating budget. When allocating these grants, the School preferences junior staff who have not had the opportunity to build up significant external research funding. In 2012, the recipients were: Item

External Research Income The School’s external research income comprises the largest fraction of the overall income of the School. It is the funding provided by external bodies to the School’s staff to undertake specific research projects. The School is a very high performing research unit within the University. Figure 1 above shows trends in internal research income. Despite the School’s growth in teaching-load driven operating income, research income continues to grow at a greater rate. Research income increased by 4% from 2011 to 2012. This was greater than recent years and reflects, in part, the growth in industry supported research. Overall the School is in a very strong financial position. Its operating income has grown from a large deficit situation in 2007 and 2008 to a strong position which has enabled a growth in academic staff. This has occurred primarily due to the growth in undergraduate and postgraduate research students.

Marketing Report The year 2012 was an eventful and fruitful year for the School in terms of marketing outcomes and activities. Highlights included welcoming for the second year in a row over 70 first year students in our four programs; engaging and retaining a high percentage of 1st year students; and hosting yet another highly successful MSE exhibition during the UNSW Open Day in September , which attracted record levels of attention and enquiries. Another significant marketing engagement activity during 2012 was our Peer Mentoring Program. Established in 2006, the program aims to help 1st year students (mentees) in their transition to University life by connecting them with experienced students (mentors) who they can meet and/or correspond with about their studies, university life or if they have any problems or queries about the courses or UNSW in general. In its 7th consecutive year the program had 21 mentors and 53 mentees, one of the largest groups of MSE students since the program’s inception. The mentees were officially welcomed during O-week with a tour of the School, followed by lunch, where they had the opportunity to meet their mentors. They were then officially welcomed by Head of School, Prof Mark Hoffman, and introduced to the School’s teaching, technical and administrative staff and to their allocated academic advisors. The second and final social event of the program was an afternoon of barefoot bowling and a BBQ at Kensington Bowling Club in the first week of April. This was the perfect opportunity for 1st years to get to know their mentors, create new friendships and for MATSOC (the Materials Science and Engineering Students’ Society) to hold their AGM and recruit new members.
Whilst the total number of Likes (219) by the end of 2012 was a conservative number, the promotional potential of a page lies in the number of Friends of Fans (89,937) and on the People Talking About This (52). These people represent the total potential reach of any content published on the page at the time - in other words free potential advertising for our School. Facebook also gave us a good insight into the demographics of our target audience including the age and gender of people who like our page. The main target audiences being 18-24 year old males (37%), 18-24 year old females ( 20%) and 25-34 year old males (18%). We can use this data to optimize the content we publish on our page to meet the needs of our target audience. Another new digital media initiative completed during the 2nd semester of 2012 was the School’s new promotional videos. What is Materials Science? Why Study Materials Science? and Postgraduate Studies and Research were produced during the last half of 2012 and included testimonies from a range of current under and postgraduate students as well as academic staff. The first two videos were released on 23 December 2012 (the day after the release of the ATAR results and also a critical time for the recruitment of new undergraduate students for 2013) and had a total of 758 views between their release and 31 December 2012. In mid-December ten school leavers were shortlisted to be interviewed for the 2013 Industry Sponsored Awards. The School then offered scholarships to worthy recipients based on their ATAR and interview performance as well as their interest in our field.
I would like to thank all the enthusiastic and cooperative staff and students that helped coordinate the various marketing The second half of 2012 kicked off with the launch of the activities and that represented our School at University or School’s Facebook page in June. The aim of the page is to Faculty wide fairs during 2012. promote our School as an interesting, exciting and friendly place to study Materials Science and Engineering. For the A special thank you to Rosalind Haskew, my predecessor, majority of our School’s target audience-prospective and who was an essential part of the administrative team of the current undergraduate and postgraduate students-social School for two years and whose hard work and contributions networking is an essential part of their daily routine hence are reflected in the high enrolment numbers of 2012 and of the need to build a strong online presence and integrate previous years and also in the success of many events and Facebook into the School’s Marketing Strategy. promotional initiatives.

Sammy Chan
Associate Professor
Professional Experience Associate Professor, School of Materials Science & Engineering, UNSW 2009Senior Lecturer, School of Materials Science & Engineering, UNSW 2003-2008 Research Contribution Sammy’s research interests are in the areas of energy-materials, hydrogen storage and metal matrix composites (MMCs). Major contributions to the fields are: (1) Identification of hydrogen trapping ability in different microstructures to provide a better understanding on the hydrogen embrittlement of steel. (2) Application of Ni encapsulation on hydrogen storage alloys in the preparation of Ni-MH battery electrodes using sintering rather than via the paste method, so that the conductivity of the electrodes can be largely enhanced. (3) Development of binder-free, highly electrical conductive buckypapers and graphene papers for MEMS, biosensors and other applications. (4) Synthesis of nanostructured Ni(OH)2 with the performance of nickel electrodes increased by 30% in capacity. (5) Development of aluminium matrix composites with nano-reinforcements. With only 1% of these reinforcements, the tensile properties of the composites are better than or comparable to those of composites with 10% micrometric reinforcements. The composites also have a very high creep resistance up to 0.8 of their melting points. Publications include 6 book chapters, 70+ refereed journal papers and similar number of conference papers. Teaching Contribution Courses are taught in the areas of Mechanical Properties of Materials, Corrosion and Corrosion Control, Surface Treatment and Wear, Specialty Alloys, Materials Design and Applications.

He was awarded his PhD in 2007 from the School of Physics at Monash University, Melbourne, Australia for work in the field of time-resolved neutron scattering in ferroelectric materials. After his PhD, he spent three years as a postdoctoral researcher within the Structure of Materials group at the European Synchrotron Radiation Facility, Grenoble, France. During this time he specialized in the application of high-energy x-ray scattering techniques to the study of functional and mechanical properties of materials, in particular, electro-ceramics. Research Contribution John’s research focuses on the understanding of the structural origin of physical properties of materials. To date, this research has been primarily directed in the field of electro-mechanical materials where a wide range of underlying structural processes at different length scales leads to the coupling of mechanical load and electrical charge. Further understanding in this area is aimed at improving the quality and range of applications of these materials, which are already used in devices such as ultrasonic imaging transducers and nano-positioning systems. Structural characterization measurements associated with this work are carried out at both neutron and synchrotron x-ray facilities in Australia and abroad. In particular, the Australian Nuclear Science and Technology Organizations, OPAL research reactor in Sydney, and the European Synchrotron Radiation Facility in France are used. John is also applying these advanced structural characterization techniques to understanding mechanical deformation in structural nuclear materials and natural biological nano-composites. John currently supervises four honours students, two Masters by Research student, and three PhD students on associated projects. During 2012, John presented his research at the International Workshop on Relaxor Ferroelectrics, Edesheim, Germany and the Asian Meeting on Electroceramics, Penang, Malaysia.

Prof. Veena Sahajwalla, in close collaboration with OneSteel, established a method by which an intractable carbon-rich waste product can be successfully supplanted for a natural resource in Electric Arc Furnace (EAF) steelmaking. In addition to being without detriment to furnace functioning or the finished product, her research has shown that carbon from recycled scrap rubber tyres can produce a more stable foamy slag compared to coke only – greatly improving furnace energy efficiency. Successfully incorporated into commercial-scale industrial furnaces operated by OneSteel over the past 4 years, this technology has now been commercialised under licence to international EAF steelmakers. The WorldFirst Polymer Injection Technology was included in the 2012 List of Innovations that Could Change The Way We Manufacture by the Society for Manufacturing Engineers. OneSteel conducted the first commercial implementation of this technology outside of Australia, at UMC Metals in Thailand in May 2011, and is in discussions with Steelmakers from Asia – South Korea, Thailand, India, Taiwan, Europe (Italy) and the Americas (United States, Canada and Brazil) regarding implementations in those countries.

Undergraduate Studies The main objective of our undergraduate program is to produce graduates who will be recognised as the best suited and most appropriately trained to contribute to the institutions and industries of Australia. For many years, the demand for graduates has well and truly exceeded the number the School produces. However, a significant recruitment effort is ensuring that there is a pipeline of high quality students who will graduate in the years to come.
Teaching Programs The major undergraduate programs taught by the School are: BE Bachelor of Engineering (Materials Eng., Ceramic Eng., Physical Metallurgy or Process Metallurgy) – Program 3135 BE/MBiomedE Bachelor of Engineering (Materials Eng., Ceramic Eng., Physical Metallurgy or Process Metallurgy) and Master of Biomedical Engineering combined program (Program 3138) BE/BCom Bachelor of Engineering (Materials Eng., Ceramic Eng., Physical Metallurgy or Process Metallurgy) and Bachelor of Commerce combined program (Program 3136) BE/BE Bachelor of Engineering (Materials Eng., Ceramic Eng., Physical Metallurgy or Process Metallurgy) and Bachelor of Engineering (Chemical Eng.) combined program (Program 3970) Student enrolment numbers in these programs are summarised in the table below. The School offers a major in Materials Science in the University's general Bachelor of Science (BSc) degree (Program 3970) and is also a major contributor to the Bachelor of Science – Nanotechnology degree (Program 3617).

New Enrolments The intake of students over the past 12 years is shown in the graph over the page. The number of students enrolling in School programs, particularly the combined BE/MBiomedE and BE/BCom programs, has increased steadily. Also shown is enrolment in the coursework masters MScTech program which has grown significantly in previous years. Entry into the BE programs is generic and students declare their major at the end of Stage 2. Process Metallurgy and Ceramic Engineering attract only small numbers of students though they are heavily influenced by the availability of scholarships. There is, however, an increasing drive for graduates who can perform strongly in a variety of environments, which drives a need for strong generic materials engineering that can support workplace learning. The BE/MBiomed program continues to attract a steady number of high quality students. In 2011, the School also introduced a new 5-year double-degree of BE (Materials)/ BE(Chemical) and 2012 saw its first intake of students.

Student quality continued to improve in 2011, with an average ATAR entry of 91.24 compared with 86.3 in 2007. This is driven in large part by a significant investment in scholarships, by both industry and the School, and a strong marketing and recruitment activity in the School. First year retention rates are complex to understand. While approximately 20% of students leave the program between 1st and 2nd year, a similar number of students are attracted to the program. However, the School continues to have the largest undergraduate program in the discipline nationwide by far. The School’s undergraduate teaching load is predominantly to domestic students. However, there is a steady and consistent increase in international students, particularly into the BE(Materials) and BSc(Nanotechnology) programs. Undergraduate teaching load includes both students studying towards a degree in Materials and students in other study programs who choose to take materials courses. Approximately, 40% of the School’s teaching load is external to its own programs. Data of the total undergraduate teaching load over the last 8 years is shown in the table below. The data shows a steady increase in the number of students the School teaches.

Scholarship Programs The School operates a comprehensive suite of scholarship programs for attracting and supporting highachieving, motivated students into its materials science and engineering undergraduate degrees. In addition to providing financial support to students, the scholarship program gives students valuable opportunities to work in the Australian materials industry as well as the chance to apply and reinforce knowledge and skills learnt in undergraduate classes. The scholarship programs are: Co-op Scholarship Program: The Co-op Scholarship program provides students with a scholarship of ~$16,000 p.a. and 68 weeks industrial training throughout the BE degree. In 2012, there were 6 Co-op scholarships funded by 6 industrial sponsors. (Refer to the separate Co-op Program report.) Industry Partnership Scholarship Program: The Industry Partnership Scholarship program provides students with $3000 p.a and the opportunity for industrial training with sponsors during summer vacation periods. In 2012, there were 12 sponsors providing over $32,000 p.a. to the School for 12 industry partnership scholarships. School Scholarship Program: The School has two perpetual scholarships established through benefactory funding from Sir Rupert Myers and the Thomson Family. The Sir Rupert Myers Scholarship commences once every 2 years at a stipend of $2,500 p.a. and is available to all students in the BE degree. The Thomson Family Scholarship commences once every 4 years at a stipend of $2,000 p.a. for students undertaking the Ceramic Engineering academic specialisation. The School also offers a number of School scholarships valued at $1,500-$2,000 depending on academic ability. Sponsors and the Scholarships awarded over the past 5 years are summarised in Table 1. Scholars are selected on the basis of written application and formal interview by panels consisting of Sponsor representatives and School academics. The Scholarships are awarded on the basis of academic performance, relevant materials experience, and interest in the discipline. All Scholars are required to maintain satisfactory academic progress throughout their academic studies and Scholar performance is reviewed at the completion of every semester. The scholarship programs provide an important contribution to education of the School's undergraduate students and comprise an important facet of the School's strong partnership with industry. The School takes this opportunity to thank its many industrial sponsors for their generous and continued support.

Industrial Training Placement Experience - Amanda Wang Biofouling is the unwanted adhesion of microbes on a surface. The Innovation Campus of the University of Wollongong and BlueScope Steel in Port Kembla collaborated to sponsor three university students to investigate the antifouling properties of a combination of polymeric colloidal dispersions with various surfactants. This research was separated into three inter-related projects. Under the supervision of Dr. Michael Higgins, my project utilised the atomic force microscope (AFM) to quantify nano-scale forces of attraction and adhesion by using functionalised hydrophilic and hydrophobic cantilevers. This aims to investigate the antifouling properties of the polymeric surfaces and relate results to their characterised surfaces. Throughout this 10 week program, I was exposed to a variety of large equipment, experimental procedures and seminars. The sponsored students were given multiple opportunities to develop presentation skills by preparing monthly progress reports and giving presentations to BlueScope Steel, as well as to academic gatherings at the Innovation Campus. I was fortunate enough to attend the 8th Annual Electromaterials Symposium, held on the Innovation Campus. Academics from across the globe met to present and share findings from their respective fields of expertise, expanding my curiosity in research being conducted in various countries. In addition to this, I was able to enter the Valentines’ Day themed poster competition, which both consolidated my understanding of the project findings, and developed useful skills in effectively conveying information in a condensed form. Industrial training over the summer of 2012-2013 has definitely sparked my interest for research. I was able to practise theory that was gained throughout the course of my undergraduate degree as well as learn to troubleshoot problems and analyse results in preparation for reports and presentations. At the conclusion of this research program, I was thrilled when my mentor informed me that the findings made from the three inter-related projects would be published and we would be recognised for this. My future career seems bright regardless of industry, as interpersonal and time management skills developed throughout this experience are applicable to all fields of expertise. My rÊsumÊ now has an additional shining sticker added to it.
Presentation Competition The Undergraduate Industrial Training Presentation evening was a great success in that it showcased our students' industrial training experiences to great effect. The quality of the posters and the 1 minute presentations was high and all students were commended for their efforts. It was particularly pleasing to see the enjoyment of everyone involved and the obvious "buzz" around the room. The industry representatives were impressed by the professionalism of the work and reiterated their support for the School's industrial training program. Congratulations to the winners: Claire Dwyer (1st prize), Thomas Sinclair (2nd prize), and Supphatuch Ukritnukun (3rd prize). Thank you also to the judges. In recognition of the high standard and effort put in by all students, Prof. Sri Bandyopadhyay kindly donated $20 UNSW Bookshop vouchers to each student. Giehard Nebre's presentation reflecting on his industrial training cadetship experiences (as far afield as Chile) rounded off the evening nicely.The function is part of the School's revised industrial training requirements and

Co-Op Program The Co-op Program is a scholarship program run with the cooperation of the University of NSW and industry to provide scholarships and industrial training for undergraduate students in various degree programs. In the School of Materials Science and Engineering, scholarships are provided by sponsors in each of the 4 academic specialisations of Ceramic Engineering, Materials Engineering, Physical Metallurgy, and Process Metallurgy. The Co-op Program is a highly visible and very effective means to attract high-quality students into our discipline. The first Co-op scholarships in Materials Science and Engineering commenced in 1989 and the success of the Coop Program in delivering benefits to scholars and sponsors in Materials Science and Engineering is demonstrated by the strong and consistent support of the Program by industry: there have been a total of 125 scholarships from 30 different industrial sponsors since 1989. Co-op graduates are highly sought by industry and those students entering the materials industry via the Co-op program usually rise to positions of leadership and management. The Co-op Program attracts the academically strongest students (typically, ATARs are greater than 99.0) who, importantly, also have good leadership, teamwork, and communication skills. For students in Materials Science and Engineering, each scholarship provides ~$16,000 per annum for 5 years, 68 weeks of structured and highly relevant industrial training with up to 4 sponsor companies, the opportunity to experience typical graduate employment, and close access to potential employers. The Program provides industrial sponsors with highly motivated, capable students to complete important and valuable industrial work. It also provides sponsors the opportunity to have direct involvement in the education and development of our School’s students, from whom they can potentially recruit their future managers and leaders. A total of 6 scholarships (Table 1) were provided by 6 industrial sponsors in 2012 (Table 2). This represents an investment by industry of approximately $100,000 for the year. Unfortunately, no new scholarships were established in 2012 and this was attributed to the continued economic downturn in the Australian manufacturing industry. One new scholarship was obtained in late 2012 for commencement in 2013. Table 1: Co-op Program in Materials Science and Engineering – 2008 to 2012 Cohort Statistics Intake Year

Scholars completed the following industrial training (IT) placements during the year: IT1 (10 weeks) by students at the end of their first year; IT2 (10 weeks) by students at the end of their second year; and IT3 (24 weeks) and IT4 (24 weeks) by students midway through their third year of study. Each IT placement was reviewed by the Academic Coordinator in the form of an interview with the scholar and sponsor representative(s). The scholar and sponsor also provided written appraisals of the placement. Each scholar gave a short presentation to industry sponsors and fellow Co-op students summarising their IT work and, importantly, the technical and professional benefit they obtained from the placement. Judging from the placement interviews, written appraisals and presentations, all placements were completed successfully and fulfilled the philosophy and objectives of the Co-op Program – for both scholars and sponsors. Industry sponsors indicated the significant quality and value of work completed by the scholars during their placements. The commitment of scholars and sponsors to the IT placements is fundamental to the success of the Co-op Program. The School thanks the sponsors for the effort they put into organising the placements as well as their training, guidance and support of scholars during the placements.

Co-op activities for the year included: welcoming function and induction ceremony for first year Co-op scholars, first year leadership camp and Co-op Working Party meeting combined with IT presentations. The Co-op program appreciates the time and effort given by Sponsors to attend Co-op functions. The academic performance of Co-op scholars in 2012 was high and significantly above that of other students, as in previous years. All scholars met the academic requirements for continuation in the Co-op Program. The online career manager system introduced by the Co-op Office in 2011 continued to be developed in 2012. This system provides a portal for scholars to maintain their current contact details, résumé (it includes a useful résumé builder), IT placement details, etc. It also provides for electronic lodgement of IT placement review forms by scholars and sponsors, as well as holding these forms as a record of placements. The career manager will be available for Scholars after they leave University as a career development tool. The School thanks all of its Co-op sponsors for their continued generous support.

Outbound Exchange Students Alan West
Holstein Wong
With the hard planning and all the days crossed off the calendar, the time had finally come to set off for exchange studies at the Royal Institute of Technology in Stockholm, Sweden. Considering the University's high standing in Engineering and Innovation and not to mention Sweden's reputation for ready-toassemble furniture, this was the obvious choice for me.
In 2012, I spent Semester 2 studying at Swansea University in Wales. All the hype about exchange is true - going on exchange was one of the best decisions I’ve made during my university life and I highly recommend it to everyone.
After a quick tour of Europe featuring frog's legs in the French Riveria, Toga Parties in Greece and a casual Bungee Jump in the Swiss Alps, I made my way to the birthplace of ABBA and Skype and where supermodels are just so common they are forced to seek employment at 7/11's. The Uni organised Sauna parties and a Swedish dinner (featuring Swedish meatballs of course) which made for an easy transition, despite having to adjust to the wacky hours of daylight.
This was my first trip to the UK, and I had an amazing time despite not knowing a single person when I arrived in Wales. The Hendrefoelan Student Village, which houses about 2000 students, became my home for four months. My eight housemates were all international students too, so we had great fun learning how to pronounce place names that had no vowels (very important if you wanted to get on the right bus) and discovering the wonders of Wind Street (seemingly innocuous but pronounced “wine” for some reason).
Then it came down to the business end of things.
The university campus is situated beside the beautiful Singleton Park and faces right onto the beach. Wales has a bad reputation for being rainy and dismal, but when the sun comes out it is a stunning place.
The University had a strong philosophy for group projects and presentations which I found to be a very effective method of teaching.
The Gower Peninsula, bordering Swansea’s western suburbs, is designated an Area of Outstanding Natural Beauty and well worth a visit.
This philosophy also meant less contact hours, which provided me plenty of time to focus on my studies... and also to plan my weekend travels, which gave me the opportunity to taste authentic Belgian waffles, share a few beers at Munich’s Oktoberfest and to go snowmobiling in Swedish Lappland.
Once you cross the cattle grid you are literally in the wild country, where animals have right of way on the roads.
By experiencing so much different culture, making friends from all corners of the globe and playing in snow like a 4-year-old, this trip became so much more than a study exchange, but a complete life changer. It opened my eyes to the world outside the G10 computer room and has built life skills, which cannot be learned until one has pushed the boundaries of their comfort zone.
Swansea also has an interesting materials science history. The copper magnates of the 19th century made their money here along the banks of the River Tawe, and the process engineer Ludwig Mond established a plant in the suburb of Clydach where he pioneered the carbonyl method for extracting and purifying nickel. I was fortunate enough to meet a process technologist who took me on a site visit (and also introduced me to Welsh folk dancing for good measure). Although I enjoyed spending time in Wales, I couldn’t pass up the opportunity to travel around the region. I had a great time exploring Ireland during the Christmas holidays - the only downside was having to go back to uni afterwards for the final exams!

Postgraduate Student Society 2012 was an exciting year for PGSOC, now in its third year since founding. PGSOC managed to hold another successful year of the School’s annual 5 minute Postgraduate Presentation Competition, won by Rama Vasudevan (now graduated). This year’s theme helped to raise the somewhat less glamourous (but no less valuable) aspect of research, with presenters focusing on issues they have encountered during their projects and the innovative and ingenious approaches used to tackle them. Helping young researchers understand that not everything will go to plan and utilizing leftfield approaches to tackle these situations is very beneficial to the school, and encourages healthy discussion about issues, which on occasion may be glossed over by students in more conventional research competitions and we are glad to have highlighted this. A number of smaller social initiatives have taken shape, with regular informal meetups and an increased level of correspondence with the postgraduate student cohort regarding issues and suggestions they have faced inside the school, leading to some simple but effective ways of improving the student spaces inside the university. In 2013, PGSOC are looking forward to hosting the Materials Science and Engineering Poster Symposium, as well as the 3rd year of the Presentation Competition, and increasing our social interactions with the student cohort with more official outings to bring together students in the school. I am also very happy to introduce three new members to the PGSOC Committee, with Lance Tang, Neil Lazo and Neamul Khansur bringing some fresh faces into the committee. I would also like to thank graduated members Alex Blagus and Sophia Wen for their contributions. We wish everyone all the best for the next year and hope it is a successful and productive one for our school’s research. Sincerely, Ronald Maran (PGSOC President)

Effect of Bias Voltage on the Microstructure and Properties of CrNbased Coatings Y. Lin, Z.H. Xie(a) and P.R. Munroe Understanding the changes in microstructure of CrN coatings under the influence of variations in processing conditions is critical to tailoring their mechanical properties for specific applications, such as, high-speed cutting tools. In this study the effects of pulsed substrate bias on both the microstructure and mechanical properties of CrN, without elevating the substrate temperature, was evaluated on coatings prepared by low frequency pulsed magnetron sputtering. High frequency pulsing bias results in a compact and dense chromium nitride coating, compared to coarse grained coating exhibiting a high density of voids in coatings prepared without the application of bias voltage (see Figure 1). The coatings prepared at a high bias voltage are also seen to be thinner, which implies a lower deposition rate. Moreover, as the bias voltage increases the structure changes from being single phase, CrN, to a two phase, CrN plus Cr2N, microstructure. This refinement in the microstructure yields a marked increase in both hardness and elastic modulus by ~342% and 92%, respectively. The fine and hard structure developed under a negative bias voltage of 80 V is also expected to possess a greater resistance against the flank and crater wear of coated cutting tools during machining operations. Increasing the bias voltage increases the energy of ion bombardment during the deposition process, which subsequently increases adatom mobility and hence results in a denser coating. Further increasing the energy of ion bombardment may generate point defects or lead to re-sputtering from the growing surface. It is nitrogen atoms that are preferentially sputtered from the growing surface due to their lighter mass, which results in a Cr-rich two phase chromium nitride film and a lower deposition rate.

Synthesis of Silicon Nitride Xiaohan Wan, Guangqing Zhang (University of Wollongong) and Oleg Ostrovski Silicon nitride is an advanced ceramic material; it has excellent high temperature properties: high strength and hardness, resistance to creep, oxidation, and thermal shock. This project studied synthesis of silicon nitride by carbothermal reduction/nitridation. Samples were prepared from silica-graphite mixtures in the form of pellets. Carbothermal reduction of silica was investigated in a fixed bed reactor at 1300-1650 째C in nitrogen at 1-11 atm pressure and in hydrogen-nitrogen mixtures at atmospheric pressure. The extent of reduction (xSiO2) of silica was defined as the fraction of oxygen removed from SiO2 by the reduction. The extent of nitridation, defined as Si3N4 yield (ySiN4), was calculated as the fraction of Si in the form of Si3N4. Similarly, the extent of carburisation, defined as SiC yield (ySiC ), was calculated as the fraction of Si in the form of SiC. Phase development in the process of carbothermal synthesis of silicon nitride is shown in Figure 1.
Figure 1: Si distribution between SiO2, Si3N4, and SiC in fumed silica reduced in the 10 vol% H2-90 vol% N2 gas mixture at 1450 째C. Gas flow rate was 1 L/min; C/SiO2 molar ratio was 4.5.
Production of Si3N4 by carbothermal reduction/nitridation has a relatively narrow temperature interval: at high temperatures, SiC has higher thermodynamic stability than Si3N4; at low temperatures, reaction is too slow to be feasible. The highest yield of silicon nitride in reduction in nitrogen at 1 atm was obtained at 1450 oC. Increase in nitrogen pressure can increase silicon nitride stability at high temperatures with a positive effect on its synthesis. Table 1 shows the elemental composition, weight loss, extent of reduction and yield of silicon nitride and silicon carbide in reduction of silica in nitrogen at 11 atm pressure. The reduction rate of SiO2 increased with increasing temperature; the highest silicon nitride yield was obtained at 1600 oC. Table 1: Carbothermal synthesis of silicon nitride in nitrogen under pressure 11 atm
It was also established that hydrogen addition to nitrogen promotes the silica conversion rate; H2 can be directly involved into the reduction or/and by forming CH4 by reacting with C. The maximum Si3N4 to SiC ratio was obtained with addition of 10 vol% H2 at 1450 째C. Higher H2 addition led to lower N2 partial pressure with a negative effect on Si3N4 formation. Silicon nitride can be decomposed to silicon and nitrogen in an inert gas atmosphere and/or under reduced pressure at temperatures above 1600 oC.

Preparation of Bismuth Ferrite (BiFeO3) Ferroelectric Thin Film by Sol-Gel Processing Peggy Zhang, Owen Standard and Nagarajan Valanoor Bismuth ferrite (BiFeO3) belongs to the class of multiferroic materials because it exhibits simultaneously ferroelectric, antiferromagnetic and piezoelectric properties. Furthermore, owing to its high ferroelectric Curie temperature (TC=820-850°C) and antiferromagnetic Neel temperature (TN=350-380°C), the multiferroic properties of bismuth ferrite are relatively stable thus making the material a promising candidate for applications in magnetic and ferroelectric devices. Commonly, such devices are in the form of thin films on substrates with the films being deposited by techniques such as chemical vapour deposition, pulsed-laser deposition, sputtering etc. However, such techniques are not amenable for commercial production owing to need for expensive, specialised equipment and the inability to coat large quantities of material. Sol-gel deposition by spin coating is a widely-used chemical deposition method for ceramic films and offers the following advantages over the other methods: low-temperature deposition, high compositional and microstructural uniformity over relatively large areas, high preparation efficiency and low cost. Collectively, these advantages make it an attractive technique for commercial production. Only limited work on sol-gel deposition of BiFeO3 films has been reported in the literature and most of this has indicated that the complex chemistry and chemical preparation route make it difficult to obtain pure, dense and defect-free thin films (Fig.1). In particular, the presence of porosity in films invariably lead to current leakage (“short-circuiting”) between upper and bottom electrodes during electrical measurement and thus renders the films useless for practical electromechanical applications. The overall objective of the present work was to develop a viable sol-gel deposition route for the fabrication of high-quality, leakage-free BiFeO3 films. A nonaqueous sol precursor system based on 2-methoxyethanol and acetic anhydride as the solvent phases with Bi and Fe nitrate as the chelating metal species was used. Extensive studies of the chemistry (using techniques such as Fourier-transform infrared spectroscopy and nuclear magnetic resonance) underlying the initial gelation behaviour of the system were completed. Formation of a continuous Bi-Fe-gel coating was dependent on the competing kinetics of solvent gelation and solvent evaporation. Gelation involving the metal nitrates and the solvent is needed to form a coherent, continuous gel layer but, for the system used in this work, this is driven by the evaporation of the solvent itself. If the solvent evaporation is too slow then this promotes crystallisation of non-stoichiometric phases within the film. If the solvent evaporation is too fast then there is insufficient time for gelation and, instead, a powdery coating is obtained. By optimisation of the heating rate, gelation temperature, and metal nitrate to organic solvent ratio, it was possible to produce a continuous gel coating of relatively high Bi and Fe concentration which, on subsequent heat-treatment, yielded a single-phase, near fully-dense, and continuous thin film of BiFeO3. An example of a film ~45 nm thick, is shown in Fig. 1. The crystallography, nanostructure, and electromechanical properties of the coatings will be examined in the next stage of the project, with the intention to produce coatings for potential commercial applications.

Numerical investigation of the dispersion in dry powder inhalers Z.B. Tong1, B. Zheng1, R.Y. Yang1, A.B. Yu1, and H.K.

Inhalation aerosols offer the distinct advantage of rapid and convenient delivery of bioactive substances to the site of action. However, present pharmaceutical dry powder inhalers (DPIs) are extremely inefficient (only 10–30% of the stated dose reaches the lungs) and have large variability of dosing. This work investigates powder dispersion mechanisms in pharmaceutical dry powder inhalers, using the commercial AerolizerŽ as a model inhaler device. A coupled CFD and DEM technique was adopted to simulate fluid flow and particles, respectively. The shear stress of turbulent flow had no visible effect on powder dispersion while the agglomerateagglomerate interactions occurred only when the agglomerates were ejected from the capsule. Multiple major impactions occurred between the agglomerates and the chamber wall, which fragmented the agglomerates into large pieces without generating many fine particles. The subsequent impactions between the fragments with the grid were identified as the key factor for the dramatic increase in FPF. The inhaler was more efficient with increasing air flow rate in terms of the FPF, but its performance decreased at higher flow rates due to increased device retention. (a)

Characterization of dilatation failure of composites using fractography Carole Autori and Alan Crosky Efficient design of structures from fibre reinforced plastic composites requires an accurate knowledge of the load at which failure will occur. Several empirical theories, based on mathematical descriptions of observed mechanical behaviour, have been developed for this purpose. While each provides good prediction for particular ranges of situations (eg, fibre orientation, stacking sequence, etc,) none is universal in application. Traditionally it has been considered that the matrix in a composite simply holds the fibres in the required orientations, however, failure is in fact initiated in the matrix when the loading direction is greater than about 10째 to the fibre direction. Thus, except over the very narrow range of orientations where the load is within 10째 of the fibre orientation, onset of failure is determined by the properties of the matrix. Recognising this, workers from Boeing have developed a physically-based theory, known as the Onset Theory, in which molecular dynamic modelling of the polymer matrix is used to predict the onset of failure. The theory considers that matrix failure occurs by either dilation or distortion. The work shown below was undertaken to evaluate the predictions of the Onswet Theory for dilation failure.

SEM images of the crack tip with the fibres parallel to the plane of section.
SEM observation provides a two dimensional understanding of the crack path, however, the failure mechanism is a three-dimensional phenomenon. Focused ion beam milling was therefore used to examine the fractographic features in the third dimension and this has provided a considerably enhanced understanding of the processes that occur.

The study has confirmed that the fractographic featured present in the specimens are consistent with dilatation failure. The observation of replicate samples suggests that these features are reproducible. Annual Report

FTIR study of curing of composites involving bi-functional epoxy and milled carbon fibre for use as modified matrix for CFRP systems Sri Bandyopadhyay, S T Cholake, G Moran (UNSW); Y Bai, R K Singh Raman, XL Zhao (Monash University); S. Rizkalla (NCSU, USA) This research focusses on the crosslinking mechanisms (FTIR peaks) of epoxy resin reinforced with 1, 2, 3, 5 and 10 wt % of cheap ball milled carbon fibre (MCF) obtained from a European supplier. FTIR spectra of virgin liquid DGEBA epoxy show two characteristic peaks at 3056 and 915cm-1 representing C – H stretching and bending vibrations in epoxy group respectively. When a crosslinking agent (cycloaliphatic polyamine, CAPA) is added to this epoxy, highly active epoxy rings (oxygen connected to two different carbon atoms, see diagram below) open up forming new bonds converting the system into heavily cross-linked rigid material. Using this mechanism, the extent of reaction can be calculated by determining the percentage opening of the epoxy group, i.e., decrease in peak 3056 and 915cm-1 [1] (Figure 1). Optimum curing time was found out using FTIR to cure liquid DGEBA into rigid solid at room temperature with the help of CAPA hardener.
Figure 1 Characteristic peaks of liquid and rigid epoxy along with EMCF 01 (1 % MCF)
Figure 2 Quantitative study of effect of different % of MCF on epoxy group reaction
Using equation 1 given below [2], it is observed that DGEBA attains maximum cross-linking (i.e., 97 and 89%) at the 915cm-1 and 3056cm-1 peaks after 8 days and remains constant after that.
A new peak at 1740cm-1 representing formation of carboxyl group is observed in EMCF composite series. The possible reason behind this is while blending the MCF with liquid epoxy resin, the secondary alcohol group present in epoxy group at 1297 cm-1 reacts with the anhydride ring of MCF leading to the formation of carboxyl group at 1740cm-1 [3]. Effect of addition of MCF on epoxy group reaction varies as MCF wt % is changed. A primary conclusion from Figure 2 data is that that above 3% MCF, the composite shows improved crosslinking due to less formation of carboxyl groups. So the concentration of MCF must be greater than 3 %. References 1.

Buckypaper/MmNi5 Composite Film for Ni/MH Batteries
Binder-free and highly conductive buckypapers made of multi-walled carbon nanotubes have been used as a substrate for MmNi5 hydrogen storage alloy electrodes (Mm= mischmetal). A good contact between the buckypaper and the MmNi5 alloy was established by magnetron sputtering. Electrochemical results show that the buckypapers can be a versatile replacement for conventional metal substrates for the anode in Ni/MH batteries. The obtained maximum discharge capacity of 276 mAh/g (Fig. 1) was significantly higher than that previously obtained on thin-film electrode with metal substrate, which was around 220 mAh/g. The high rate discharge capacity was also improved considerably. This provides a valuable platform for the realization of thin-film Ni/MH batteries. 2.
Buckypaper-based bionanosensor (BNS)
Novel bionanosensors using buckypapers as substrates have been developed, which is able to effectively detect DNA-hybridization with controlled device resistance. Modeling of the sensors using pole-zero plots in the z-plane suggests the reorientation of carbon nanotubes within the buckypaper in the presence of hybridized-DNA in the high frequency range (12–16 MHz). Our results successfully demonstrate the possible application of buckypaper as in-situ bionanosensors (Fig. 2).

Origin of Long-Range Ferromagnetic Ordering Among Metal-Organic Frameworks with Antiferromagnetic Dimeric-Cu(II) Building Units Jiabao Yi Metal-organic frameworks (MOFs) are porous network structures consisting of metal oxide clusters linked by molecular chains. This new class of materials show a number of promising applications in gas storage,1 luminescent materials,2 molecular sieves,3 drug delivery,4 and catalysis, 5 Meanwhile, many MOFs exhibit unique magnetic property due to the constitutive open-shell transition metal (TM) ions, which have been attracting much attention because of their potential applications in low density magnetic materials, molecular magnets, and magnetic molecular sensors. By both theoretical and experimental approaches, we uncover the origin of magnetic moments and long-range ferromagnetic (FM) coupling among metalorganic frameworks (MOFs) constructed with antiferromagnetic (AFM) coupled dimeric-Cu(II) building unit. It is revealed that copper vacancies are the origin of local magnetic moments which are coupled via conjugated aromatic linkers. Figure 1 shows the hysteresis loops at 5 and 20 K, indicating the Curie temperature is lower than 5 K and larger than 20 K. Susceptibility (Fig. 1b) measurement indicates that the Curie temperature of the MOF-505 is around 11 K. In order to understand the ferromagnetism mechanism, we used first principle calculations to investigate the origin of ferromagnetism. Fig. 1c shows the perfect structure of MOF-505. No spin density can be observed. However, when Cu vacancy is introduced into the structure, spin density can be observed around the Cu vacancy (Fig. 1d, 1e). Spin density can be both observed in one single or pair Cu vacancies. This work has shown that cation vacancies in MOF-505 can induce ferromagnetism, which may pave a way to explore and realize some new high Tc dimeric-Cu(II) based ferromagnetic MOFs.

High Piezoelectric coefficients in Ba(Zr0.2Ti0.8)O3-(Ba0.7Ca0.3)TiO3 Lead-free thin films Danyang Wang and Bingcheng Luo The industry is currently facing global restrictions on use of lead-based piezoelectrics because of the high toxicity of lead. Therefore, it is an urgent task to develop lead-free alternatives with piezoelectricity comparable to those of lead-based materials. Binary system (1-x)BaZr0.2Ti0.8O3xBa0.7Ca0.3TiO3 (BZT-BCT) has been recently recognized as a promising lead-free piezoelectric material with a morphotropic phase boundary (MPB) near x=0.5. This finding shed a new light on the research of lead-free piezoelectrics and great efforts thereby have been made to study the microstructural, elastic, dielectric, pyroelectric and piezoelectric properties of BZT-BCT ceramics. However, studies on BZT-BCT thin films are still insufficient. In our work, high quality BZT-BCT thin films were fabricated on La0.7Sr0.3MnO3-coated SrTiO3 single-crystalline and semiconductor silicon substrates by off-axis RF magnetron sputtering. A strong dependence of ferroelectric and piezoelectric properties on the crystallographic orientations of the thin films was observed, attributing to the relative alignment of crystallites and spontaneous polarization vector. A large effective piezoelectric coefficients d33,eff of 100Âą5 pm/V was obtained in our BZT-BCT thin films. The d33,eff values of our thin films are very much comparable to those of lead-based thin films, and are in the upper range of lead-free piezoelectric thin films reported in the literatures up to this date, suggesting that BZT-BCT is a promising candidate to replace the widely used lead-based piezoelectrics for the applications in high-performance microelectronic devices. In addition, the established orientation-property relationship in our epitaxial thin films may provide a valuable guidance on further development of textured BZT-BCT based materials.

Controlling high temperature corrosion of steels in CO2-rich gases by alloying Thuan Nguyen, Jianqiang Zhang, David J. Young Oxyfuel combustion is an emerging technology designed to reduce emission of CO2-rich gases at high temperatures in the power industry. In the oxyfuel process, coal is combusted in oxygen rather than air, resulting in a flue gas consisting mainly of CO2 and H2O. This gas is surprisingly corrosive and the selection of appropriate steels to handle these gases is challenging. Carbon dioxide and water vapor are destructive, and degrade the Fe-Cr and Fe-Cr-Ni steels used widely in heat exchangers. Modification of these steels by adding minor alloying elements (Ce, Mn and Si) is a conventional approach to improving their high temperature corrosion. Our research showed that alloying with Si significantly reduced the oxidation weight gain kinetics of a 9Cr alloy (Fig. 1). Very little weight gain was recorded when adding only 0.2wt% Si. Without any Si addition, 9Cr steel suffered severe oxidation and carburisation, forming thick multi-layered iron oxide scales and intergranular carbides within the alloy (Fig. 2a). However, with the 0.2 wt% Si addition, a very thin protective Cr2O3 oxide scale was formed together with an SiO2 layer about 20nm thick underneath the Cr2O3 scale (Fig. 2b). Internal carburisation was then suppressed.

Simulation and Modelling of Particulate Systems (SIMPAS) The research conducted at the Laboratory for Simulation and Modelling of Particulate Systems (SIMPAS), led by Aibing Yu, Federation Fellow and Scientia Professor, aims to understand and model the physics governing particulate and multiphase processing, with its application oriented to mineral/metallurgical/ material/chemical industries. Over the years SIMPAS has developed a sustained and systematic way to study particulate matter at various time and length scales including, for example, the determination of contact forces between particles at an atomic or sub-particle scale, dynamics of particles at a particle scale, and performance of an operational unit at a process equipment scale. The outcomes of Professor Yu’s research include theories, computer models and simulation techniques, and knowledge at both microscopic and macroscopic levels. Such multiscale research is critical to advancing particle science and technology, as well as process technology. Below are a few examples highlighting SIMPAS work.

SIMPAS DIRECTOR’S REPORT Much of our environment and the benefits that we derive from our surroundings are strongly influenced by the interactions of the three primary phases of matter – solids, liquids, and gases. These interactions often occur on surfaces, with the individual phases being discrete in form. Particles/powders, which can be either wet or dry and range in size from nanometers to centimeters, are one very important example of such a multiphase system. As with solids, bulk powders can withstand deformation; as with liquids, they can flow; as with gases, they exhibit compressibility. These features give rise to another state of matter – particulate matter – that is poorly understood. Particulate science and technology is a rapidly developing interdisciplinary research area with its core being the understanding of the relationships between micro- and macro-scopic properties of particulate materials. It is now emerging as a core competency of paramount importance to many sectors of our modern economy. The macroscopic behavior of a powder is controlled by the interactions between individual particles as well as interactions with any surrounding gas or liquid. Understanding the microscopic mechanisms in relation to these interaction forces is key to leading to truly interdisciplinary research into particulate matter, in which scientists and engineers correlate their findings and ensure that microscopic predictions from one discipline match macroscopic results from another. It is extremely difficult to obtain microscopic information experimentally, even with the use of advanced and expensive measuring techniques. However, this difficulty can be overcome by computer simulation and modelling. This point of view has been widely accepted among the scientists working in this area, particularly in recent years as a result of the rapid development of discrete particle simulation techniques and computer technology. The Laboratory for Simulation and Modelling of Particulate Systems (SIMPAS) is a world class, multidisciplinary research facility established and directed by Professor Aibing Yu, ARC Federation Fellow and UNSW Scientia Professor. Its research theme aims at understanding the mechanisms governing particulate packing and flow through rigorous simulation and modelling of the particle-particle and particle-fluid interactions at both microscopic and macroscopic levels, with its application oriented to mineral/metallurgy/chemical/materials industries. Its goal is to be internationally recognised through excellence in fundamental and applied research in particulate science and technology. Its mission is: • to establish a world-class interdisciplinary research team, supported by the rapidly developed computational techniques and computer technology, in the field of particulate science and technology; • to provide a forum to research scientists from various disciplines for exchanging ideas and developing collaborative research in computational particulate technology; • to promote the application of particulate science and technology, newly developed understanding and research techniques in particular, to industry; and • to contribute to the education and training of high quality postgraduates in particulate science and technology. The research in SIMPAS is developed in five inter-related areas at three levels, including the development of simulation and modelling techniques (level 1), fundamental studies of particle packing and flow, and the transport properties of static/dynamic particle systems (level 2), and industrial application (level 3), as shown in Fig. 1.

The School continues to play a major role in the Centre and is active in several of its research projects. Professors Michael Ferry and Mark Hoffman have continued with their major leadership roles in the two key research programs. The above flowchart shows Program A consisting of the six projects in Al, Mg, and Ti, and Program B consisting of two projects in Hybrid Materials and Surface Engineering. Program C involves linkage projects with various industry partners and Program D involves research associated with the European Accelerated Metallurgy project. Selected research highlights of UNSW researchers in two key projects are outlined below.
Project A4 – Lightweight Bulk Metallic Glasses
Researchers: Prof. Michael Ferry (Project Leader), Dr Kevin Laws (Project Manager), Dr Martin Xu, Dr Reza Mahjoub, Jake Cao, Karl Shamlaye, Jacky Cao, John Scicluna, Fitri Mohamad, Olga Biletska, David Miskovic, Nick Hamilton Lightweight bulk metallic glasses (BMGs) have a metastable amorphous structure and, hence, they generally exhibit attractive properties suitable for structural and mechanical applications. This major Centre project has three streams of research: Stream A aims to extend the types of BMG compositions based on a fundamental approach to alloy design of BMGs and involves investigations of their microstructure at the highest levels of sophistication; Stream B aims to generate actual devices and components for certain end-applications, and Stream C aims to generate BMG composites and components. Again, 2012 has been highly productive year for this project with one notable research outcome being the explanation of the structural origin of enhanced ductility in our Mg-based BMGs using a combination of molecular dynamics modelling and advanced high energy x-ray scattering studies at ESRF.
Project B1.1 – Hybrid Design for Exceptional Structural Performance – Low Density Structures
Researchers: Prof. Mark Hoffman (Program Leader), Dr Tania Vodenitcharova (Project Manager), Neil Lazo, Dr Emmanuel Flores-Johnson This project targets lightweight structures with optimised architecture and material selection which provide superior capabilities over their bulk counterparts. It explores foam- and trusscored laminates for their high absorption capacity, and bio-mimetic shell-based structures optimised to meet specific strength and performance requirements. Inspired by naturally occurring nacre structures, a new project stream ‘Bio-inspired composite structures’ commenced, which aims to develop a layered nacre-like structure of high impact resistance. The figure below shows: (a) nacre-like structure comprising bonded waving solid plates, and (b) FEA simulations of a projectile impacting the structure at various speeds. The ballistic performance of the composites was compared with that of bulk plates and was found to be superior in thicker-plates impacted at high velocity. This is attributed to the hierarchical structure that enables both localized energy absorption by deformation of the metallic tablet and tablet interlocking due to the waviness and inter-layered delamination which allows plastic deformation further away from the impact zone.

SMaRT DIRECTOR’S 2012 REPORT Scientia Professor Veena Sahajwalla Director of Sustainable Materials Research and Technology Centre (SMaRT@UNSW) The SMaRT Centre has broadened the environmental mantra of ‘reduce, reuse and recycle’, adding ‘re-forming’ of waste materials, demonstrating commercially viable research outcomes and promoting a wider understanding of the immense potential benefits of sustainable materials and innovative manufacturing processes. Our commercialised ‘green steel’ making process is now turning waste polymers and tyres into steel in Australian and overseas factories. Ongoing and new research programs apply a similar innovative approach to waste streams, including complex and challenging automotive waste and e-waste. We have also transformed mass agricultural wastes into novel building materials. My appointment as Commissioner on the Federal Government’s Climate Commission focuses on ‘solutions’ and represents an important public endorsement of the SMaRT Centre’s goal for leading scientific and engineering advances in the sustainability of materials and associated technologies. The singling out of ‘green steel’ by the Banksia Environmental Foundation, through its 2012 GE Eco Innovation Award for Individual Excellence, gave further prominence to our pursuit of industrial-scale innovations in sustainability while referring to our “…holistic approach to sustainable materials and processes” and achieves rare success in bridging “…the space between academia, industry, government, environmental groups and the public”. At SMaRT, waste is viewed as an opportunity, not a burden. If we reduce, reuse, recycle and reform waste as much as possible, we can meaningfully reduce pressure on the world’s natural resources, reducing both energy use and emissions. In 2012, SMaRT was granted a total of $966,000 in research funding. Funding sources were primarily from the Australian Research Council and industry partners such as OneSteel, LKAB Sweden and the Australian Coal Industry Research program. However, a new grant over three years from the Australia-India Strategic Research Fund allows us to broaden our research agenda and international links. In partnership with prestigious Indian research institutes and UNSW’s Faculty of the Built Environment, the SMaRT Centre will initiate research into the novel reprocessing of complex e-waste, that has low recycling rates due to complex mixes of metals, plastics and hazardous toxic components and which is one of the world’s fastest growing and most challenging waste problems. Informal e-waste recycling in developing countries employs crude heating methods to extract precious metals, such as gold and silver, exposing workers and communities to serious health risks and the environment to toxic dangers. The UNSW-led team aims to develop safe, small-scale processing plants to help local communities threatened by hazardous leaching from landfill, or toxic fumes, and to protect waste workers. Research continues with our key industry partner, Arrium Ltd, formerly OneSteel, into a novel recycling approach which aims to extract silicon-carbon resources from glass from automotive waste glass and plastics. International Research Collaboration included staff and students from University Malaysia Perlis; POSCO, South Korea; Saudi Basic Industries Corporation; and the University of Mines and Technology, Tarkwa, Ghana. Exchange students came from Sweden and Canada while exchange researchers from MEFOS, Sweden, worked collaboratively on SMaRT research. We continue to build international collaboration with leading research institutions and our collaborative research funding for e-waste will lead to a visit from India’s Institute of Minerals and Materials Technology.

Leading industrialist and philanthropist, Rajan Tata, visited Kensington campus to receive a Doctor of Business honoris causa and give UNSW researchers an unprecedented opportunity to discuss innovative environmental solutions with the leader of one of the world’s most influential business groups. Representing the SMaRT Centre, I outlined the potential for the application of our sustainable research in India, where environmental issues are increasingly challenging. Mr Tata’s visit followed the success of last year’s Symposium on Sustainable Materials, Processes and Technology that fostered international research collaboration and brought together innovators from around the globe and, in particular, from Australia’s neighbouring regions. 2012 offered many opportunities for me to encourage young women to consider careers in science and engineering as part of a national publicity campaign involving outstanding Australia women. As the Nokia Business Innovation Award recipient in 2011, I was able to speak about research and innovation outside familiar academic circles and contributed to various publications with broad audiences. A direct consequence of that award was an encouraging interest of women’s magazines in the life of female scientists. Senator Kim Carr, Federal Minister for Innovation, Industry, Science and Research described the SMaRT Centre as an important model for collaboration between researchers and industry, “This is where white collar meets blue collar. It is the best way to get new knowledge out of the academy and into the real world.” 2012 has seen the further consolidation and productive collaboration he envisaged across all our areas of endeavour, from research to public engagement, both locally and internationally. We owe our every success to those who have supported us in pursuing our vision. I take this opportunity to thank the inspiring people with whom I work, and our vital industry partners and supporters.
