Environmental Science & Technology Building a Magnet for Scholarship and Support

This rendering of the BEM Complex shows the Environmental Science & Technology Building with the completed Institute for Bioengineering and Biosciences in the foreground.

Contractors and construction workers are hard at work on what will be not only Georgia Tech’s largest building on campus, but also Chemical Engineering’s future home.

The Environmental Science and

Technology Building (ES&T) has become one of the cornerstone buildings on Tech’s everimproving campus, and has attracted both individual donors and corporate supporters. ES&T will be one of three state of the

art facilities included in the planned BEM complex; Biotechnology and Biomedical Engineering, Environmental Science & Technology, and Molecular and Materials Science Engineering. The 270,000 square foot building will house multi-disciplinary learning and research areas within Chemical Engineering, Environmental Engineering, Earth and Atmospheric Sciences and the Technology Development Center.

Among the most generous of alumni supporters is Mr. Thomas L. Gossage, ChE 56, who has made a $2.5 million commitment that will appropriately name the Atrium of ES&T the Thomas L. Gossage Atrium.

Professor Gary W. Poehlein Retires after 22 Years of Service to Georgia Tech Colleagues gathered in the Gordy Room of the Wardlaw Center overlooking the Georgia Tech Football Stadium on October 23, 2000 to toast and roast a dear friend and mentor, Gary W. Poehlein. A graduate of Purdue University, Dr. Poehlein received his Bachelors, Masters and Ph.D. in 1958, 1963 and 1966, respec-

tively. He moved to Atlanta from Lehigh University in July 1978 to become the Director of the School of Chemical Engineering, and also act as interim Director of the School of Materials and Science Engineering at the time the School was formed.

From July 1985 to July 1993, he served the administration and

students of Georgia Tech as Associate Vice President of Graduate Studies and Research. In 1993, he transitioned into the role of Professor in the School of Chemical Engineering, and in 1997, he left Atlanta for Washington D.C. to serve as a Program Director at the National Science Foundation. He has been there

Capital Campaign Ends on a High Note hreshold of a New Era: The Campaign for Georgia Tech officially ended on December 31, 2000. Five years, 52,720 donors, 40 Roll Outs, 52 new faculty chairs, and $711.973 million later, Georgia Tech successfully completed the largest fund raising initiative in its 115-year history. The School of Chemical Engineering played a large role in the fundraising activities, raising a total of $30.6 million, $5.6 million over the School’s $25 Million goal.

During these past five years, ChE has secured five new faculty chairs and more than $11 million in endowment funds. The accompanying illustration gives a breakdown of the funds raised during the campaign.

Campaign Fund Statistics

Never before has the School been so well positioned for financial security. The funds available for student scholarships and graduate fellowships will dramatically effect the makeup of our student populations. In addition, the resources allocated to student and school programming will continue to enhance the rankings of the school among competing ChE departments. While ChE recognizes the generosity and faith of the many alumni and corporations who supported the School during the campaign, it is critical that we continue to look for ways to fund new initiatives in the coming years.

If you would like more information on making a charitable gift to Chemical Engineering, be it a multi-year pledge, a deferred tax savings vehicle, or a stock transfer, please contact Ms. Kelsey Evans at 404-894-0987, or e-mail her at kelsey.evans@che.gatech.edu.

hen a Dublin manufacturer of recycled newsprint had trouble scaling up new flotation technology, it called on Georgia Tech for help with the $1.2 million investment. SP Newsprint, formerly Southeast Paper Manufacturing, began using a pilot version of a new technologically advanced system called the Lawson tubes separation system.

The system removes contaminants from aqueous solutions of recovered paper fiber. However, when the company tried to scale up the system from a pilot version (which processes 100 gallons per minute) to a commercial version (which processes 7,000 gallons per minute), the Lawson tubes separation system failed to meet performance standards. When no one at the company could agree on the problem or solution, Alan Lawson, vice president at the company, suggested the company consult with Georgia Tech.

Amyn Teja gave the plenary lecture entitled “The Solubility of Solids in Dense Fluids” at the XV Congreso de Termodinamica in Oxaca, Mexico in September. While in Mexico, he also visited the Mexican Institute of Petroleum in Mexico City and presented a talk on “Wax Deposition in Natural Gas Systems.” Dr. Teja also gave an invited talk at the 3rd China/USA Joint Chemical Engineering Congress held in Beijing in October, 2000. The talk was entitled “The Thermodynamics of Dilute Mixtures in the Critical Region.”

Jude Sommerfeld gave a talk this past year on “Batch Process Simulation” to the local Albany/Tallahassee Section of the American Institute of Chemical Engineers. The meeting was held at the Merck pharmaceutical manufacturing facility located in Albany, Georgia.

Paul Kohl was recently granted three new patents: Fabrication Procedure for Integrated Planar Cavities with Applications to Displays and Advances Hybrid Systems, Drabik, T., Kohl, P.A., Patent #6,141,072; Air-Gaps for Electrical Interconnections, P.A.

Lawson consulted with Georgia Tech EDI engineer Alan Barfoot of the Dublin office, who then found the best Georgia Tech expert to analyze the problem ~ Dr. Jeffery Hsieh, Director of Pulp and Paper Engineering at Georgia Tech and a professor in the School of Chemical Engineering. Lawson had only two questions for Dr. Hsieh: “Why is the system not working and can it be made to work?” Hsieh studied components of the system such as chemistry, velocity, and flow. Then he pored over performance data from the pilot to commercial scale and made recommendations and reviewed fixes with Lawson. As Lawson implemented some of Hsieh’s ideas, he provided feedback to Hsieh regarding the ongoing results.

“He had a very good idea,” Lawson said “He tried to make the pilot unit fail and perform like the commercial unit.

Instead of going forward as researchers do, his idea was to work backwards until you work out the problem. Hsieh constructed theories on why the system wasn’t working and implemented the theories on the pilot unit. This troubleshooting process quickly and inexpensively verified the problem’s true cause, one that everybody could agree on.”

Within five weeks, Dr. Hsieh was able to get the Lawson system operating. “Hsieh didn’t necessarily solve everything,” Lawson said, “but because he narrowed that focus down and came in as independent, he came up with a logical approach for us to use.”

Lawson projects that if the Lawson Separation system is fully implemented across the Dublin mill, cost savings could be significant. In addition, the technology could be licensed to others. Prior to the Lawson system ink removal capacity was limiting, and bleaching chemical consumption was very high on the mill’s number one paper machine. The company is

Chemical Engineering Welcomes Four New Faculty

T

he School is proud to announce the addition of four new faculty members: Assistant Professors Christopher Jones and Carson Meredith and Professors Jay Lee and Andreas Bommarius. Drs. Meredith and Lee are featured in this issue with in-depth articles on their backgrounds, interests and future plans. Articles spotlighting Drs. Jones and Bommarius will appear in the next newsletter.

Dr. Jay Lee Professor Jay H. Lee comes to Georgia Tech with ten years of teaching and research experience. Prior to joining ChE this fall, he was a faculty member at both Auburn University in Alabama and Purdue University in Indiana. He has held visiting appointments at E. I. Du Pont de Numours in Delaware and at Seoul National University in Korea. He obtained his B.S. degree in Chemical Engineering from the University of Washington, Seattle, in 1986, and his Ph.D. degree in Chemical Engineering from California Institute of Technology in 1991.

First at Purdue University and now at Georgia Tech, Dr. Lee is directing a research group called ISSICL (a name inspired by icicles frequently seen from his laboratory at Purdue), which stands for Integrated Sensing, System Identification, and Control Laboratory. As the name implies, his research focuses on integrating novel sensors, data-based modeling techniques, and numerical simulation/optimization techniques into a computer-based control system that can improve the efficiency and safety of chemical and biologi

cal processes and also enhance the quality and variety of products.

In academia, sensing, modeling and control have long been regarded as independent research disciplines and their integration for process optimization and control has largely been ignored. Advances in computing and communication technologies have made computer-based control and optimization of an entire process or even an entire plant a reality (integrated design of sensor, model and control algorithms has surfaced as an important challenge). Lee’s research group is one of the few that span the three areas and emphasize their integration.

integrated system design. The second is intended to breed tools and insights that are specific to particular process problems. These involve understanding the process from the viewpoint of control, tailoring existing tools, inventing new tools that do not exist and integrating them into a systematic solution.

called Model Predictive Control (MPC). MPC has already revolutionized the practice of process control, so Dr. Lee’s goal is to modernize a textbook that will educate the current and future engineers about the fundamentals of the technique.

The group is currently engaged in a number of application projects including the design and operation of a simulated moving bed system, startup of a mammalian cell reactor, particle size distribution control in a particulate system, product quality control in pulp digesters and polymer reactors, and spatial profile controls in microelectronics manufacturing systems. For details, please visit the group’s homepage: http://dot.che.gatech.edu/information/research/issicl.

His group is currently composed of seven Ph.D. students, a postdoctoral fellow, a visiting professor from Korea and a visiting student from Germany. The group is very active and has published more than 100 journal and conference papers. The group’s activities can be divided into two categories: The first is designed to engender tools and insights of a fundamental and general nature that will help

Dr. Lee has also been involved in writing a new graduate-level textbook that puts due emphasis on a new computer-based optimizing control technique

As this project draws near completion, Dr. Lee is in the midst of launching a new project intended to advance undergraduate control education. He intends to write a new textbook that embodies a more balanced treatment of selected topics.

Along with this effort, it is his belief that well-designed computer and web-based tools can contribute greatly to the students’ learning of abstruse concepts. Along with a visiting professor from Korea, Dr. Lee is currently co-developing a suite of web-based interactive simulation and visualization tools for undergraduate control education, with the intention of combining them with the new textbook. On a more general

level, Dr. Lee is a strong proponent of tighter integration of the curriculum. He sees the current curriculum as an accidental result of the historical evolution of various chemical engineering science domains.

He is interested in bringing to Georgia Tech a more goaldriven, tightly-integrated curriculum, in which the role of each topic is made clear to the students in a problem-solving context.

His effort and achievement in control research and education have brought him several honors. Notably, he was a recipient of the National Science Foundation’s Young Investigator Award in 1993 and the Alumni Research Award given by the Auburn Alumni Engineering Council in 1996.

He currently has a number of research contracts with national agencies like the National Science Foundation and Department of Energy as well as with companies like Aspen Technology, DuPont, Weyerhaeuser and Honeywell.

However, the awards he cherishes the most are the ones that past students have given him, such as the Kimberly Clark Mentoring Award that he received last fall at Purdue University.

On the personal side, Jay Lee was born in Seoul, Korea and immigrated to the U.S. during his high school years. He is currently married with two daughters and the family lives in Alpharetta. He enjoys golf, hiking and other outdoor activities and likes the climate here better than that of Purdue, but regrets that, with two little chil-

dren and a long commute, little time is left for diversions.

Rather than focusing on a single application, his research centers on the fundamentals of phase transitions, self-assembly, and stability in these materials.

In this way, discoveries tend to apply to several applications at once. Two unique approaches are used to carry out this research: combinatorial methods and computer simulations.

Dr. Carson Meredith Professor Carson Meredith joined the School of Chemical Engineering faculty in July 2000, after finishing a two-year postdoctoral position at the National Institute of Standards and Technology (NIST) Polymers Division, in Gaithersburg, Md. Prior to that, he completed his Ph.D. in Chemical Engineering at the University of Texas at Austin in 1998.

He received his Bachelors in Chemical Engineering from Georgia Tech in 1993.

Combinatorial methods were originally developed for pharmaceuticals research in the early 1990s to allow rapid and comprehensive measurements over large numbers of reactants and conditions. The goal of Dr. Meredith’s approach is to apply these techniques to characterize colloidal and thin film materials.

These highthroughput methods lead to faster development of process models and new pathways for materials processing. The key is preparation of thin film and colloid samples that contain thousands of compositions and process variables each, over an area the size of a microscope slide. He recently developed three such methods for thickness, composition and temperature variation in polymer films.

These samples, called combinatorial libraries, are then coupled with automated microscopy and spectroscopy to allow measurements over a broad range of variable combinations in orders of magnitude

Excited to return to his alma mater, he directs the Advanced Polymer Thin Film and Colloid research group. The primary goal of this research effort is fundamental thermodynamic and kinetic characterization of polymer thin film and colloid advanced materials.

The applications of these nanometer-to-micrometer scale materials include novel optical communications and data storage devices, biomedical materials, nanotechnology, sensors, as well as conventional coatings, paints, and adhesives. A common example is hard disk drive surfaces, which are coated with an approximately 2 nm thick film of fluorinated polymer to provide lubrication and protection of the magnetic

less time than with conventional methods.

This combinatorial technique was recently applied to study the stability of thin polymer coatings on silicon surfaces, a problem that is relevant to the preparation of microelectronics packaging and optical coatings.

When thin films become unstable, they begin to break up and de-wet the surface, much like rain drops beading up on a waxed car. By studying combinatorial libraries that contain about 1800 variations in temperature and thickness each, Dr. Meredith discovered a new relationship governing the kinetics of film de-wetting over a wide range of temperatures and thicknesses. The technique has also been applied to investigate phase separation of polymer mixtures and the interactions between cells and biomaterial coatings.

Under certain conditions of composition, temperature, and pressure, colloidal and nanoscale particles spontaneously arrange into ordered, crystalline arrays that have special optical properties. A common and beautiful example of these colloidal crystals is the formation of natural opals from silicate particles, noted for their rich diffraction of colors. By learning to control precisely the self-assembly of colloidal particles, engineers can build new types of advanced electronic devices and optical switches for communications.

The key, however, is learning to control the thermodynamics of self-assembly.

He uses computer simulations to investigate self-assembly Continued next page

More than 50 colleagues, many from outside the School of Chemical Engineering, gathered to bid a fond farewell to Gary and his wife, Sharon Poehlein, who attended the event with three of their four children. Dr. Poehlein hired many of the School’s faculty members during his first few years at Georgia Tech. Several of the faculty recalled their

favorite memories and first impressions of Gary Poehlein.

The recurring theme however, was the great impact that he had on the School. In his eight years as Director of the Department, he hired more than 15 faculty members, increased the graduate school’s enrollment from 10 to 100, and helped to propel the School to national recognition.

His energy and commitment were cornerstone to the Department’s success over the years.

Ron Rousseau, the current School Chair, presented Gary with a crystal vase inscribed with the Institute Seal and the following words: “In appreciation of your contributions and leadership, School of Chemical Engineering, Georgia Institute of Technology, 1978 ~ 2000.

Ron Rousseau presents Gary Poehlein with a crystal vase at his retirement celebration.

Dr. Teja recalls some favorite memories of Gary and Sharon Poehlein: . . .inviting my wife and I to “dinner” and forgetting to mention that it was a “pool party” and not a “black-tie affair” (hey, my wife and I were visitors from England, so guess what we turned up in!!!)

during the processing of colloids. With this technique, two “boxes” filled with colloidal particles are simulated on a computer. Equilibrium between the colloidal fluid and the ordered colloidal crystal is approached by exchanging particles between the boxes.

This process searches for and finds the liquid-solid phase diagram, analogous to the liquid-solid freezing of water.

Simulation describes how the phase diagram can be altered to achieve precise control over structures and provides basic thermodynamic information that can be translated into process design applications.

In his previous position at NIST, Dr. Meredith developed new techniques to create combinatorial libraries of polymer thin films. He also discovered a new phase transition for blends of biodegradable polymers. This means that using temperature, one can control how well these polymers mix, altering the mechanical and barrier properties. These biodegradable polymer mixtures are useful in tissue engineering, drug delivery and for degradable packaging.

at the graduate and undergraduate levels. He also plans to develop a new Surface Science and Chemistry course to be offered as an elective to undergraduates and graduates. This course will be taught as a team with other professors in the department.

Becoming a professor is not the only new thing in Carson Meredith’s life: on February 13, 2000, his first child, Lorraine “Kate” Meredith, was born. He resides in the Atlanta area with his wife, Jennifer, a signlanguage interpreter for the deaf. When at home, he enjoys jogging and spending time with his wife, daughter, and blackand-white Springer Spaniel (Gershwin).

He will teach chemical engineering courses that relate to his research interests. These include Numerical Methods (ChE 2120) and Thermodynamics (ChE 2110 and 3110)

A Message from the Chair A Message from the Chair

Professor Ronald W. Rousseau tions and the many brochures that are sent to our constituency.

The External Advisory Board welcomed four new members to the October meeting: Dr. Robert C. Armstrong, ChE 70, Dr. Cecil C. Chappelow, Charles (Chuck) A. Hall, ChE 85, and Mr. James P. Harris, ChE 70 (corporate affiliations listed on page 3). Dr. Richard M. Gross, Vice President of R&D, Dow Chemical Company rotated off the Board after our October meeting, but we are grateful for all that he has done on behalf of the School throughout his 12 years of service.

The School of Chemical Engineering was founded in April 1901, so this spring marks 100 years of ChE at Georgia Tech! Engineering Chemistry, as it was called back then, started with only two students and three Ph.D. faculty members.

Compared to today’s 800 students and 36 faculty members, I’d say we have done quite a bit of growing. In fact, there are not many chemical engineering programs that have been in existence as long as we have. We intend to celebrate the Centennial with a special series of seminars in the fall semester, a homecoming event in October, and other exciting initiatives. I invite you to send in your thoughts regarding other appropriate activities to mark this exciting benchmark.

The annual College of Engineering Alumni Awards Ceremony was held in October, and a number of chemical engineering alumni were honored. It was especially gratifying to have six ChE alums inducted: Thomas C. DeLoach, ChE 69, into the Hall of Fame; C. Garry Betty, ChE 79, Sandra A. Fryhofer, ChE 79 and Larry J. Bloom, ChE 72 into the Academy of Distinguished Engineering Alumni; and Jeffrey L. Brinen ChE 85, Ph.D. 89 and Cheryl A. Perkins, Chem 83, ChE 89 into the Council of Outstanding Young Alumni. I know there are additional alumni deserving of recognition. Please help us to honor them by submitting nominations to me for future awards.

As you have read on page 2, Georgia Tech completed the Capital Campaign on December 31, 2000. I am pleased to report that both the Institute and Chemical Engineering exceeded their goals, thanks to the many generous alumni, corporate partners and friends of the School.

As you can see from the cover, construction has begun on the Environmental Science and Technology (ES&T) building. We have spent many hours over the past few months going through building plans in order to maximize the space allocated for chemical engineering. I am pleased to report that we will have classroom, seminar, lab, conference and lecture hall space designated for ChE in this building.

It is a pleasure to announce that Dr. William J. Koros has accepted our offer of the Roberto C. Goizueta Chair in Chemical Engineering. Bill has been a faculty member at the University of Texas, where in addition to developing an outstanding research program in membrane science and technology, he served as chair of the Department of Chemical Engineering. He will start at Georgia Tech in fall 2001.

This fall we hired Josie Giles to be our External Communications Specialist. She has been a tremendous addition to the School, and I now wish we had hired her much sooner. She has been instrumental in redesigning the ChE website, and is also producing our newsletter, our publica-

As you may have noted from our Strategic Plan, http://www.che.gatech.edu/information-plan.htm, we wish to produce the most capable chemical engineers in the world, and to have our graduates recognized for their excellent technical, leadership, and teamwork skills. We set several goals in our pursuit of this objective, including the formulation of a 130-hour (not counting PE) curriculum with sufficient electives to provide students the flexibility to supplement their core education, broaden the knowledge and skills that sustain life-long learning, and enhance their opportunity to obtain a minor or certificate.

9

With lots of effort from the Undergraduate Curriculum Committee (chaired by Mark White) and area committees in a number of fields at the core of Chemical Engineering, we developed a curriculum that we think will meet many of our goals. The Institute Undergraduate Curriculum Committee has now approved our proposed curriculum, and it will become effective with fall 2001. Among the things it achieves are the following: • 18 hours of electives, 12 hours of technical electives, three of which must be in Chemical Engineering, and six hours of completely free electives.

• Integration of course work – faculty committees have worked on developing linkages in several areas, especially in the transport phenomena and separations sequence, the thermodynamics and physical chemistry sequence, and the process design and safety sequence.

• Greater opportunities for our undergraduates to participate in faculty-led research. This will give students a view of the frontiers of our discipline, bring them into closer contact with faculty members, and, we hope, stimulate a higher fraction to consider pursuit of advanced degrees.

Improvement of the facilities for laboratory courses is another action called for in our Strategic Plan. Under the leadership of Joe Schork and Bill Ernst, and with the assistance of Joe Polinsky and Elaine Thompson, great progress was made over the summer and into the fall semester. The process control lab was completely revamped, with about three-fourths of the hardware replaced and all of the electronics and software updated. Several new experiments, including a packed-bed absorption and CSTR, were put into the unit operations lab. Within a few weeks a new extraction column experiment will come on line.

We will continue to be guided by our Strategic Plan and encourage you to view it and related material on our web site. As in the past, I urge you to let me know if you have questions or comments on any aspect of the School’s programs…Let us hear from you!

1974 Artie Schroeder, BChE 74/MChE 76 has recently formed a new business called Energy Valley. Headquartered in Houston, Texas it brings money, marketing and management to early stage companies possessing technologies and talent of potentially extraordinary value to the energy industry. The company addresses a void created in the last several years as major energy producers and service companies have moved away from technology development in an attempt to shore-up short term profits during a period of low product prices. As prices continue to firm, Energy Valley’s technologies are expected to play a significant role in increasing energy production in a safe and environmental responsible manner.

1988 Steven R. Alexander, BChE 88/PhD ChE 92, is a Senior Production Engineer for Celanese Chemicals Europe GmbH. After graduating from

Tech, he married Christine Fullmer (Masters in Architecture, Ga. Tech 91) and went to work for Celanese (then Hoechst Celanse). They moved to Texas and now have two sons: Christopher Ray and Stefan Charles. Steven worked at the Corpus Christi Technical Center from 92 until 95 as a Development Engineer. He then started project work on an Acrylic Acid facility expansion in Clear Lake, Texas for 95 and 96 and worked on the project team for a Greenfield Acrylic Acid and Butyl Acrylate complex in Böhlen, Germany from late 96 until early 98. He transferred off this project team and worked as a Process Engineer at the Acrylic Acid expansion facility in Clear Lake for 98. In early 99, He went to Germany for the construction of the Böhlen project as a Production Engineer, which is wrapping up.

He says, “building and operating a plant in the former East Germany has been a real experience. Working with construction contractors that spoke no English and no German was very interesting. We had contractors on site from nearly every country in Europe. It’s amazing what you can accomplish with pictures, mime, and shouting. However, start-up was on time, under budget and on spec. We have spent the last year working out a few bugs and getting the German staff trained and experienced.

In Clear Lake we had the luxury of a fully trained staff.

In Germany we had to start from scratch, in a foreign language. I hope to be moving on to my next assignment in June of 2001. It will probably be back in the States, but I have no firm idea at this point what it will be or where.”

1998 Class Contribution to the 2000 AIChE National Student Design Competition

Dr. Wilber B. Ratterree of Athens, Georgia on April 26, 2000. Dr. Ratterree was retired from the University of Georgia.

As a follow up to the article “2000 AIChE National Student Design Competition� which appeared in the Summer 2000 issue, it is important to acknowledge that hard working Tech students enrolled in the ChE Plant Design course in spring of 1998 solved a preliminary version of the problem. The early version had not been written with the contest in mind; however, after the authors saw the quality of the solutions by some of the Tech students and their high level of interest in the subject, they decided that with some modifications, the problem would be ideal for the contest. The authors learned much as a result of the efforts of the Tech class. For example, for the National Contest problem we felt it necessary that the scope be reduced a slight bit, that more data on various unit operations and reactors be provided, and that driving conditions be more well defined.

1939 John Clayton Jacobs, Jr. of Brenham, Texas on May 21. Mr. Jacobs retired in 1980 as vice chairman of the board of Texas Eastern Transmission Corp. Mr. Jacobs, who graduated from Yale Law school in 1948, earlier had served as an attorney in Dallas and, before law school, as an engineer. He was a member of Omicron Delta Kappa and Alpha Chi Sigma engineering fraternities and Beta Theta Pi social fraternity.

The fact that the 1998 class had already solved a version of this problem was purposely withheld from the article for security reasons, because at the time the article was written, the National contest was taking place. The input of the students from the class of 1998 was acknowledged during the AIChE 2000 National Meeting in Los Angeles this fall, when Dr. Matthew Realff presented to the judges the solution to the problem during the session on the Contest Problem. No solutions were sent to AIChE from either the 1998 or 2000 classes at Georgia Tech.

Mr. Charles C. Rippberger of Albuquerque, New Mexico on July 20, 2000.
