Facilities at SCME High Performance Liquid Chromatography (HPLC) A Perkin Elmer Model Series 200 is located inside the facility. Deuterium and tungsten lamps are used as light sources. This model is connected to UV/Visible and fluorescence detectors. Wavelength range is 190-700 nm. High performance liquid chromatography is basically a highly improved form of column chromatography. Instead of a solvent being allowed to drip through column under gravity, it is forced through under high pressures of up to 6200psi. That makes it much faster.
Gas-Cromatograph-MassSpectrometer (Gc-Ms) GC/MS Model Clarus 500 (Perkin Elmer) is located inside the facility to analyze VOCs, petrochemicals, pharmaceuticals, and energetic materials. The gas chromatograph can be employed with a capillary column. The carrier gas usually utilized is He and its flux is controlled digitally. Once separated the analytes are detected by means of a quadrupole mass-spectrometer, equipped with an EI ion source.
Fourier Transform Infrared Spectrometer (FTIR) A Perkin Elmer Model Spectrum 100 is used for analysis. This instrument covers the wavenumber ranges 7800 cm-1 - 350 cm-1. Fourier transform infrared spectroscopy is a technique which is used to obtain an infrared spectrum of absorption, emission, and Raman scattering of a solid, liquid or gas. FTIR spectroscopy will be performed on a Perkin Elmer spectrometer with MCT or DTGS detector and KBr beam splitter for the mid-IR. Spectra can be collected with various resolutions by using scans. The sample chamber is purged by N2 during the measurements. The band positions, shape, and peak intensity decide the characteristics of functional groups.
Thermogravemetric & Differential Thermal Analyzer (TG/DTA) A Perkin Elmer Model Pyris Diamond TGA/DTA is used in our lab. This instrument works at the heating rate of 0.01oC/min to 200oC/ min. The temperature ranges from RT to 1500oC. TG/DTA refers to simultaneous application of TG & DTA to one sample in a single instrument. TG is based on the measurement of mass loss of material as a function of temperature. In thermogravimetry a continuous graph of mass change against temperature is obtained, when a substance is heated at a uniform rate or kept at constant temperature. A plot of mass change versus temperature (T) is referred to as the thermogravimetric curve (TG curve). TG curve helps in revealing the extent 9
SCME / Annual / Star Magazine of purity of analytical samples and in determining the mode of their transformations within specified range of temperature. In DTA the difference in temperature between a substance and a reference material is measured as a function of temperature. The DTA curve provides information regarding different events that have taken place as a result of heating. These events may include glass transitions, phase transitions, crystallization, melting, sublimation etc
Rheometer The REOLOGICA Rheometer is used to measure the rheology of the fluids. Rheology is concerned with the study of the behavior of real materials when subjected to an external force. These materials can be anything between a liquid like oil or water, and an elastic body, like rubber. Rheometer is used for the fluids that cannot be defined by a single value of viscosity and therefore require more parameters to be set. The REOLOGICA Rheometer is designed to be used in combination with a computer working with the instrument software.
Gel Permeation Chromatography (GPC) Gel permeation chromatography model VE-2001 is located inside the facility. GPC is a type of size exclusion chromatography (SEC) that separates analytesons on the basis of size. The technique is often used for the analysis of polymers. It is often necessary to analyze polymers both to analyze them as well as to purify the desired product. When characterizing polymers, it is important to consider the polydispersity index (PDI) as well as the molecular weight. Polymers can be characterized by a variety of definitions for molecular weight including the number average molecular weight (Mn), the weight average molecular weight (Mw), the size average molecular weight (Mv)or the viscosity molecular weight (Mv). GPC allows for the determination of PDI as well as Mv and based on other data, the Mn, Mw and Mz can be determined.
Bomb Calorimeter The Koehler K88800 Automatic Calorimeter, is located in SCME, offers a compact, integrated modular design for convenient operation. Heat of combustion is determined in this test method by burning a weighted sample in an oxygen bomb calorimeter under controlled conditions. The heat of combustion is computed from temperature observations before, during and after combustion with proper allowances for thermochemical and heat transfer corrections. Either isothermal or adiabatic calorimeter jackets can be used.
Velocity of Detonation (VOD) Meter Explomet-Fo-2000 Model is used to measure detonation velocity up to 10,000 m/s at operating temperature of 0-50 oC. Time domain reflectometry (TDR) method is used to measure the detonation velocity of an explosive product. The unit uses standard coaxial fiber optic cable that can be easily acquired. A properly conducted Velocity of Detonation test can also provide information such as: consistency of detonation, product contamination or dilution, priming efficiency, stemming/decking efficiency, detonator timing accuracy, and sympathetic detonation.

Elemental Analyzer (EA) Elemental Analyzer model EuroVector Euro EA 3000 is used for the determination of carbon, hydrogen, nitrogen, sulfur and oxygen content in organic and other types of materials. It is used for the qualitative as well as quantitative elemental analysis of the samples. EA3000 is cost effective for the lowest catalysts and gas consumption. It operates with unprecedented reliability and down time.
Electrochemical Workstation The VSP is a research grade potentiostat system in a 5-channel modular chassis. This allows the VSP to add additional capability in the way of plug-in “modules� to perform a number of analytical and deposition experiments. VSP obtained for HEC project No. 1603 is mainly being used for electrochemical deposition of thin films for CIGS and CZTS based thin film solar cells. Other applications being explored include cyclic voltametery, I-V characterization, electrophoretic deposition and polarization resistance determination.
Particle Size Analyzer (PSA) HORIBA; LA-920 is being used in surface engineering laboratory for the analysis of range of particle sizes present in given sample. PSA works on the laser beam scattering principle and it is capable of measuring size ranging from 0.02 microns to 2000 microns. Samples are analyzed in form of dilute slurry. For powders, these are dispersed in their respective dispersants to achieve very fine suspension/ dispersion to perform the analysis.
Optical Profilometer (OP) NANOVEA; PS50 is used with 300micron pen to measure the surface parameters of materials. Surface parameters are being measured as per ISO4287 standard. This equipment works on principle of optical chromatism. Thickness measurements can also be performed if substrates are partially coated so that when the scan shifts from substrate to the coating, step size measurements can give the thickness values.
Surface Area & Porosity Analyzer Micromeritics; Gemini VII 2390t uses adsorption theory for measurement of surface area and pore volume of the powdered samples. 99.999% Nitrogen and Helium gases are being used. Specific surface area from 0.01m2/g and pore volume from 4 x 10-6 cm3/g can be measured. This equipment is capable of performing single & multipoint surface area, Langmuir surface area, Total pore volume, Horvath-Kawazoe data reduction, BJH pore size distribution using adsorption as well as desorption isotherms, Dubinin reports, MP-Method reports and DFT reports.

Scanning Electron Microscope (SEM) Analytical Scanning Electron Microscope (SEM) Model No JSM-6490A JEOL JAPAN.A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning it with a focused beam of electrons. The electrons interact with electrons in the sample, producing various signals that can be detected and that contain information about the sample’s surface topography and composition. The electron beam is generally scanned in a raster scanpattern, and the beam’s position is combined with the detected signal to produce an image. SEM can achieve resolution better than 3.0 nanometer.
X-ray Fluorescence Spectrometer (XRF) An X-ray fluorescence (XRF) spectrometer is used for routine, relatively non-destructive chemical analyses of rocks, minerals, sediments and fluids. It works on wavelength-dispersive spectroscopic principles that are similar to an electron micro-probe (EMPA). However, an XRF cannot generally make analyses at the small spot sizes typical of EPMA work (2-5 microns), so it is typically used for bulk analyses of larger fractions of geological materials. The relative ease and low cast of sample preparation, and the stability and ease of use of x-ray fluorescence spectrometers make this one of the most widely used analysis of ma-jor and trace elements in rocks, minerals and sedi-ments.
X-ray Diffractometer (XRD) The STOE Theta/theta diffractometer is an instrument of outstanding versatility. It combines the advantages of the Theta/theta arrangement of X-ray tube and counter with a flexible choice of beam geometry, sample holders and other attachments. X-ray tube and counter circles are driven independently, while the sample is always kept in a horizontal position. The STOE Theta/theta diffractometer provides excellent Bragg-Brentano diffraction data of high resolution. High- and low-temperature chambers and a humidity chamber are adaptable, preferably to be used with the STOE Linear Position Sensitive Detector. Measurements at low angles and thin film attachment for parallel-beam geometry allow the study of thin films and multilayers.
Corrosion Testing Equipments Corrosion Laboratory is equipped with research grade electrochemical equipments like Gamry Framework ® G 750 Potentiostat with DC 105 and EIS 300 (USA), Cathodic Protection Apparatus (Norwood UK), Anodizing Setups with computerized interface, Analytical Weight Balance 0.0001g (Shimadzu Japan), Reference electrodes, Ph Meters. Experiments can be done with a wide range of materials and corrosive environments.

Completed No. PSF/038 Indigenous Development of Formulation of Radiation Resistant Polypropylene for Industrial Manufacture of Medical Disposable Syringes Shamshad Ahmed and M.Bilal Email: shamshad_zaki@hotmail.com Ethylene oxide (Eto, a corrosive gas) sterilization of medical disposables is being phased out in advance world due to its cancerous residue (toxicity) and low degree of assurance of sterilization originating from need to control several parameters. Eto is carcinogenic mutagenic, genotoxic and a reproductive toxin. Residue is left because the quarantine time of 10 days is not observed. There is no way toxicity of ethylene oxide and ethylene chlorohydrins (produced from chlorine of PVC based gasket and ETO) can be easily avoided and there is no monitoring practice nor equipment available to do that at least in Pakistan. Priming of dialysis circulatory tube will take time .Trauma and passage of carcinogenic substance over it is ideal for inducing cancer.

result. Radiation sterilization has been adopted instead in most advance countries due to its merit of high degree of sterilization and complete and absolute freedom from any type of toxicity. Radiation sterilized syringes using FDA approved additives (sterilized at PARAS, Lahore) have been produced from modified (medical grade resin) PP and their medical quality and performance has been exhaustively tested in Pakistan, Malaysia, Vietnam and many other countries. This process is clean, uses no chemicals and there is absolute assurance of sterilization. Only parameter to control is dose, well controlled through computer aided software. Assurance is so high there is need for a biological lab. There is no residual radiation at all nor is there any adverse influence on syringes, nor induction of radioactivity in the irradiated materials at the level of 1.25MeV.

PSF Project 147 Measurement of Dielectric Properties of Nano-ceramics (R2Si2O7, R= Er, Ho, Dy and Ferrites) Asghari Maqsood Email: maqsoodasghari@gmail.com Dielectric properties of materials are important from the application point of view. A dielectric material is typically a large band-gap material (Eg greater than 4ev) ,that exhibit a high resistivity. When the term dielectric material is used it is generally understood that material is essentially a nonconductor of electricity. An electrical insulator is a dielectric material that exhibits a high break down- field. The Funds from this project were used to establish Thermal Transport Lab at scme. Eight MS and four Ph.D’s completed their research work and three Ph.D students are using the equipment at present. More than thirty papers appeared in the ISI indexed journals. It was shown that nano particles of Er2 O3 and D- Er2Si2O7 can be used for electronic devices [ A. Bakhsh, A. Maqsood: Electronic Materials Letters 8(2012)605; S. Ameer, A. Maqsood: Solid State Communication 152 (2012) 1811]. It was also concluded from the experiments that nanoferrites are good microwave absorbers. For more detail see paper by H. Anwar, A. Maqsood: Electronic Materials Letters 9(2013)641. This graph shows the reflection loss as a function of frequency and composition, for detail see paper by Anwar and Maqsood.

HEC Project No. 1-28/HEC/HRD Establishment of a Molecular Nanotechnology Laboratory Habib Nasir Email: habibnasir@scme.nust.edu.pk Molecular nanotechnology is relatively a new field of science which is growing very fast. Most of the bottom-up synthesis approaches to nanotechnology are based on supramolecular chemistry. Supramolecular chemistry is one of the most important innovations in chemistry in the recent years. It focuses on the noncovalent bonding interactions of molecules. Unlike traditional organic synthesis, which involves the making and breaking of covalent bonds to construct a desired molecule, supramolecular chemistry utilizes far weaker and reversible noncovalent interactions, such as hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions, and/or electrostatic effects to assemble molecules into multimolecular complexes. The important concepts in supramolecular chemistry include molecular self-assembly, molecular recognition, host-guest chemistry, mechanically-interlocked molecular architectures, and dynamic covalent chemistry. The increasing control over the arrangement of atoms will create new possibilities for manufacturing nanotechnological devices such as self-healing polymers, chemical sensors, compact information storage
devices for computers, high-performance catalysts for industrial processes, and development of new pharmaceutical therapies by understanding the interactions at a drug binding site. This project aims to establish the facilities to synthesize nanomaterials/macrocyclic compounds by using the pseudo high dilution synthetic procedure. These substances will be used to study host-guest chemistry with neutral molecules, cations and anions. The inclusion complexes of toxic metal ions have important use in cleaning drinking water and industrial waste treatment. The macrocyclic guest molecules can also be used as smart nanosensors in order to specifically detect and quantify the toxic metals ions e.g. cadmium, mercury, arsenic lead, copper, iron and strontium etc. So far 4 MS students have completed their research work and 2 Ph.D students are still working using the facilities of this project. 15

Inprogress HEC (NRPU) No. 20-1564 Synthesis of Hydroxyapatite and its Products Development for Biomedical Application Mohammad Mujahid (PI), Amir Habib (Co-PI) Email: principal@scme.nust.edu.pk Any material that functions in the biomedical field and is designed for the biological system is called biomaterial. Hydroxyapatite (HA) is a form of bioceramic that is chemically similar to bones and hard tissues found in humans. Synthetic HA is biocompatible and do not cause any harm or toxicity. It is also the principal component of natural bone with a chemical formula [Ca10(PO4)6(OH)2], and occurs in hexagonal system. About 70% of the bone constitutes of hydroxyapatite with calcium-to phosphorous ratio of 1.67. Due to its excellent biocompatibility, synthetic HA it can be rapidly integrated into human body. In addition, owing to its bioactive property, HA is widely used in medicine and dentistry as a material for metallic implant coatings or for bone cavity fillings. It is believed that nano structured calcium phosphate ceramics can further improve the properties of HA including bioactivity, biocompatibility, solubility, sinterability, fracture toughness and absorption which can be tailored over wide ranges by controlling the composition, size and morphology of the powder particles. For these reasons, it is importance to develop synthesis methods for HA which are focused on the

HEC Project No. 20-1603 Fabrication, Characterization, and Testing of Copperindium-galium-(di) Selenide (CIGS) Based Thin Film Solar Cells for Power Generation Mohammad Mujahid Email: principal@scme.nust.edu.pk Pakistan is facing serious power crisis due to ever increasing demand and limitations of conventional hydroelectric power generation resources. During the summer season, the shortfall between power generation capacity and consumer requirements exceeds 6000 MW, thus leading to extensive hours of load-shedding and shutdown of power supply to major industries. On the other hand, solar energy is abundant in this region throughout the year and can be harnessed if, though not very effective yet cost-effective, photovoltaic technology is developed first in research laboratories and at an industrial scale. CIGS based thin film technology employs the use of chalcopyrite compounds of typical composition Cu(InxGa1-x)(Se2-ySy) as p-type semiconductor absorber coating. The other component thin films are: molybdenum (Mo) as back contact electrode, cadmium sulphide (CdS) as buffer layer, and intrinsic and aluminium-doped zinc oxide (ZnO:Al) as front contact transparent conducting oxide (TCO) film. In contrast with established vacuum processing based technology, we propose development of CIGS thin film solar cells and modules primarily based on solution-based processing techniques over cheap, flexible substrates such as soda-lime glass (SLG), polyimide, and metal foils. Adoption of simple, inexpensive solution-based synthesis routes such as spin coating, dip coating, doctor blading, spray pyrolysis, and electrochemical deposition using appropriate precursor solutions and pastes are expected to significantly reduce the cost of electricity produced, expressed as US dollars per peak watt ($/Wp). Using nanocrystals made through colloidal synthesis and inkjet printing process, role-torole manufacturing of modules can be explored. PV as a potential renewable technology will not only reduce load on the national power grid, remote areas can also benefit

With a global trend to have less dependence on conventional energy resources and to explore renewable energy technologies, it is need of the hour that direct conversion of sunlight into electricity (photovoltaics) is explored as a major, viable source for power generation.

Pakistan Norway Institutional Cooperation Program CO2 Capture from Natural and Flue Gases by Using Polymeric Membranes Arshad Hussain, May-Britt Hagg Email: arshad.hussain@scme.nust.edu.pk Membrane gas separation (MGS) is the pressure driven process with different industrial applications and represent only a small fraction of potential applications in refineries and chemical industries. With the serial production of commercial polymeric membranes since 1980, MGS has rapidly become a competitive separation technology. Differently from conventional separation unit operation (e.g., cryogenic distillation, absorption and adsorption processes), MGS does not require a phase change. Moreover the absence of moving parts make MGS systems particularly suited for use in remote locations where reliability is critical; in addition the small footprint makes them very attractive for remote applications such as offshore gasprocessing platforms. Up until now the commercial membranes material for gas separation has basically been polymers like poly imides, polyamides and cellulose acetates. This is still the situation, however the research on tailor made materials for specific gas applications has nearly exploded. These new materials include research on advanced polymers with ultra thin skin (membrane) layer, polymers with selective carriers, nano-composites (polymers with a dispersed inorganic phase), other types of mixed matrix materials (organic + inorganic materials), surface modified in-organic materials, or in general ion conducting materials . Pakistan is a developing country and due to its ongoing industrial growth and urbanization, there is alarming rise in CO2 emissions. Recently, Lahore, second largest city of Pakistan has been categorized as one of the most polluted city in the world by WHO. Pakistan has many natural gas reserves like Qadir pur, Swan and Sui gas fields etc. These gas reserves are huge source of natural gas which is being used as main source of fuel for domestic and industrial use. Natural gas is also being used as a fuel for vehicles and as a feed stock for process industry. A part from CH4, natural gas also contains significant

amount of CO2, depending upon the reservoir. Therefore, CO2 capture from natural gas termed as Pre combustion CO2 capture, is important to increase the fuel efficiency avoid the corrosion in natural gas pipe lines and reduce the CO2 emission. Moreover, the power generation sector (mainly using fossil fuel) along with chemical process industry, oil refineries, steel and cement industry are the huge source of CO2 emission in the atmosphere. A membrane based gas separation process offers a great potential for CO2 capture from the industrial exhaust gases (flue gases).This type of CO2 is termed as Post combustion CO2 capture. In view of above, there is a need to synthesize polymeric membrane which can capture CO2 with high permeability and selectivity. Therefore this proposed work will be focused on the development of polymeric membranes for carbon dioxide capture from natural gas and flue gas. The primary objective of this proposal is to develop the polymer membrane which will lead to an integrated, cost effective membrane based separation process which would be environment friendly and less energy intensive.

HEC (NRPU) No. 20-1326 Synthesis and Characterization of Spinel Ferrite Nanoparticles Iftikhar Hussain Gul, Asghari Maqsood Email: iftikhar.gul@scme.nust.edu.pk Spinel ferrites of Fd3m space group having the general formula of MFe2O4 (M=Co2+, Ni2+, Mn2+,Mg2+, Zn2+) is a class of hybrid functional materials which are very important for many recent technical designing of electrical, magnetic and microwave devices. They are considered hybrid as they exhibit good electrical and magnetic characteristics at one time in high frequency applications. An important advantage of ferrites is the huge compositional variability by the substitution of different cations in the parent crystal structure (cubic closed packing of tetrahedral and octahedral sub-lattices) and this variation in cation distribution impacts many physical properties of these ferrites such as increase in DC resistivity, low dielectric losses and required magnetization characteristics. Cobalt ferrite is partially inverse spinel material while nickel ferrites are materials having inverse spinel lattice with semiconducting nature and both exhibits high resistivity, along with moderate magnetization, magneto resistance and very high magneto crystalline anisotropy. These properties can be tailored by proper choice and composition of trivalent cations (Al3+, Cr3+, Gd3+, Ho3+,

and Nd3+) to replace Fe3+ in the parent lattice of cobalt ferrite caused by a structural variation in the host lattice. Not only a single cation but a combination can be incorporate into the parent ferrite structure to make a mixed ferrite system. Some of the works are available where a divalent cation substitution in cobalt and nickel ferrites enhances the electrical behavior of cobalt ferrites. Cations of Cr3+, Gd3+and Al3+ have been doped in the parent crystal structure of ferrites and structural, electrical and magnetic properties have been studied to see the influence of doping cations on electrical properties in high frequencies. Three masters and one PhD student are working under this project to synthesize different composition of spinel ferrite nanoparticles and to enhance the electrical and magnetic properties of the material for the use in very high frequency and ultra high frequency. There is a drastic change in electrical properties due to substitution of trivalent cations in the cobalt and nickel spinel ferrites. DC resistivity has been increased 1000 times as compared to parent ceramic material.

HEC (NRPU) Project No. 20-3066 Development of LCs Based Biosensor for the Detection of Environmental Pollutants and Pathogens Zakir Hussain (PI), Muhammad Shahid (Co-PI) Email: zakir.hussain@scme.nust.edu.pk
Liquid crystals (LCs) are a state of matter that has properties between those of a conventional liquid and a solid crystal. For example, an LC may flow like a liquid but its molecules are oriented in a crystal like fashion. Liquid crystals exist in various phases and these phases differ from each other regarding orientation of molecules and the amount of order present. Orientation of LC molecules is very sensitive to foreign particles and can be tuned by the nature, size and shape of foreign particles. Moreover, LCs also possess the property of optical anisotropy and may appear bright or dark under cross polarizers depending upon their orientation. These two properties when combined together form the basis of LC based sensors (an example is shown below, left hand sides of both figures (state a) is dark and right hand sides (state b) is bright). When we make an LC-lipid layer at the in-
terface by considering key-lock principle, we are able to detect the presence of any foreign substance, specifically. Liquid crystals based sensors are cheap, portable and do not require highly sophisticated instruments. In this project, we want to develop an LC based sensor for fast, selective and cost effective detection of environmental pollutants, pesticides and pathogens like bacteria (e.g. Escherichia Coli, Enterococci faecalis, Klebsiellaspp pneumonia and Staphylococcus saprophyticus). Evaluation criteria based on simplicity, sensitivity, specificity, reliability, speed, robustness, user-friendliness and costeffectiveness will be addressed. Milestones of the proposed project are to build up proof of concept (POC) for an IP portfolio, protecting the use of LC in high resolution sensing in air.

HEC Project No: 20-3052 Preparation, Characterization and Product Development of poly(L-lactic acid)/HA Nanocomposites Ahmad Nawaz Khan (PI), Mohammad Mujahid (Co.PI) Email: ahmad.nawaz@scme.nust.edu.pk
PLLA is a biodegradable thermoplastic polymer and because of its good mechanical property, biodegradability and non-toxic degradation products, it is being used for number of application from biomedical to conventional thermoplastics.
Fig. 1: Chemical Structure of Poly(L-lactic acid) (PLLA) [1].
It is known that the rate of hydrolytic degradation of PLLA is strongly affected by the degree of crystallinity. Therefore, it is well expected that the crystalline lamellar organization plays an important role for controlling the degradation rate. The study on the crystallization of PLLA is, thus, of great importance not only from academic interest but also from the engineering viewpoint. Three crystalline forms (ι-, β-, and γ-crystal) have been reported for PLLA depending on the preparation conditions. A variety of physical properties such as mechanical and electrical properties of polymorphic polymers considerably depends on the crystalline structure. As far as the biodegradable polyesters are concerned, their biodegradability is also influenced by the crystal modifications. For this reason, regulating the crystal modifications of polymorphic polymers and its impact of controlling the lamellar organization by the addition of nanofiller is an important approach to tailor the final properties of PLLA. Although PLA has modulus and tensile strength comparable to petroleum based polymers, however PLA has relatively much lower thermal and impact resistance properties. Inorganic or organic nanoparticles have been incorporated to enhance the mechanical, barrier and thermal properties of PLA. Unlike, micro-and macro-scaled particles e.g. talc, glass fiber, carbon particles etc., nanoparticles can improve material properties at much lower added quantities (1-5 wt %). The heightened interest for these nanofillers can be attributed to their ability to dramatically improve material properties of the nanocomposites structures as compared to neat polymer. Depending on the compatibility and strength of interfacial interaction between the polymer matrix and nanofiller, three different types of polymer based nanocomposites are thermodynamically achievable as shown in Fig. 2,
Fig. 2: Illustration of different types of structural formation of nanofiller in the polymer [2].
Nano powder of hydroxyapatite (HA) will be incorporated into the PLLA matrix. HA of varying aspect ratio, shape (rod or flake shape) and sizes will be dispersed in the PLLA matrix. The structure, crystallization kinetics, physical and mechanical properties as well as the biodegradability/biocompatibility of PLLA/HA nanocomposites will be investigated using x-ray diffraction, scanning electron microscope, atomic force microscope, polarized optical microscope, differential scanning calorimetry, dynamic mechanical analysis, extensometer and thermogravimetric analysis.

HEC Project No.20-2462 Production and Characterization of Graphene and its Application in Nanocomposites Noaman Ul-Haq Email: noaman@scme.nust.edu.pk The graphene offer comparable mechanical and electrical property enhancements, graphene-based materials appear to provide larger thermal conductivity enhancement as well as the advantage of improving barrier properties. Pristine graphene materials are unsuitable for intercalation by large species, such as polymer chains, because graphene as a bulk material has a pronounced tendency to agglomerate in a polymer matrix. It is likely that oxidation followed by chemical functionalization will facilitate the dispersion and stabilize graphene to prevent agglomeration. The functional groups attached to graphene can be small molecules or polymer chains. The
chemical functionalization of graphene is a particularly attractive target because it can improve the solubility and processability as well as enhance the interactions with organic polymers. We aim to exfoliate graphite into graphene and functionalize it by using different process like amination, esterification and isocyanate modification. Also the electrochemical modification of graphene will also be carried out using ionic liquids. The graphite oxides will be prepared from naturally occurring graphite. After oxidation, several chemical methods will be used to obtain soluble graphene.

Student Research Projects Titania nanostructures for Dye Sensitized Solar Cells (DSSC) Name: Sofia Javed
Supervisor: Dr. Mohammad Mujahid
Pakistan lies in a region where there is plenty of sunlight throughout the year so development of efficient solar cells would be very advantageous to meet the increasing energy demands.Among various types of solar cells dye sensitized solar cells (DSSC) possess great potential for low cost, easy fabrication, low temperature processing and several other advantages along with high efficiency. The configuration and working of DSSC is shown in figure 1. The cell consists of a photoanode made of dye infused nano-titania on ITO coated glass, a counter electrode made of Pt and an electrolyte between the two electrodes. The working involves the electron injection from the photon excited dye into the conduction band of titania which through ITO flows in the external wire. The electron deficiency of the dye is circumvented from redox electrolyte, which completes its deficiency from the
counter electrode, thus completing the cycle. The photoanode material ‘titania’ is under major research focus. Nanoparticulate powders have been successfully prepared by a novel method and characterized to be having phase purity (anatase), less than 10nm crystallite size and BET surface area of around 125 m2/g. Mesoporous thin films using these powders have also been fabricated and characterized. Vertically aligned titania nanotubes using anodic oxidation of Ti film have been produced and characterized in a recent MS thesis work. Research on 1 D nanostructures i.e. nanotubes and nanorods of titania using wet chemistry is also underway in a PhD project and presentable results are being obtained with a modified method. Some novel natural dyes are extracted and tested for their performance in DSSC in a BS project.

Development and Characterization of Elastomeric Based Sponge and Auxetic Structures for Impact Energy Absorption Applications Name: : M. Arshad Bashir Auxetic materials have a negative poisson’s ratio (NPR). They become thicker, when stretched perpendicular to the applied force. This happens due to their hinge-like structures, which flex on stretching. Auxetic materials can be a single molecule or a particular structure of macroscopic material. Such structures are expected to have mechanical properties such as high energy absorption and fracture resistance. These materials are of interest due to the possibility of enhanced mechanical properties such as shear modulus, plane strain fracture toughness and indentation resistance. Therefore, studying of these non-conventional materials is indeed important from the point of view regarding fundamental research and possible practical applications, particularly in medical, aerospace and defense industries (e.g., protective clothing, body armour, bullet-proof vest, “smart” sensors, sonar, panels etc). The method used for the manufacturing of auxetic structures contains four stages:

Fabrication of CNT-Aluminum Nanocomposite for Aerospace Applications Name: : Muhammad Mansoor
Supervisor: Dr Muhammad Shahid
The recent trends to strengthen the matrix using filler materials are rapidly transforming from macro- or micro- scale fillers to nano-scale fillers. Carbon nanotubes (CNTs), being one of the candidate materials, hold a strong promise to augment not only localized but also global physical and mechanical properties of the composite. During last decade, numerous researchers have quoted their work encompassing amelioration in mechanical and physical properties of CNT-Aluminum composites, however, in each case major limiting factors remained same i.e., dispersion and wettability of CNTs. The prime objectives of the proposed research are: • to synthesize mono-strand CNTs which may render easy dispersion in the composite • fabrication of CNT-Al composite by PM & casting routes with increased wettability of the CNTs • prototype production of CNT-Al composite • surface treatments of the CNT-Al composite (e.g. anodizing) and to study the corrosion behavior in various mediums
Various theoretical and conceptual models have proven the fact that better dispersion and increased wettability of CNTs, not only strengthens the matrix but also render unique physical properties e.g., tailorable electrical and optical characteristics. For alleviated dispersion of CNTs, an approach of CNTs synthesis would be adopted, which may yield mono-stands of CNTs with larger aspect ratios, lesser extent of entanglement and surface defects and for improvement in wetting capability, maneuvering of CNTs’ surface characteristics will be customized using functionalities, surface reactivity by fluxing in meltingcasting and process control agents in ball milling.

Membrane Module Design & Analysis for Gas Separation Name: : Muhammad Ahsan
Supervisor: Dr. Arshad Husssain
Membranes have gained an important place in process industry and are being used in a broad range of applications. The modeling of flow dynamics and concentration polarization in membrane module/channels is very useful. Computational fluid dynamics (CFD) is a very important tool and can be used to investigate the flow dynamics in different membrane modules. This research can help to optimize the design of membrane module by investigating the influence of concentration polarization on the gas flux through the membrane. Moreover, the implications of flow nature (laminar/turbulent) and its influence on the module performance would be interesting to investigate. The outcome of this research will be useful for the optimum design of membrane module. This work will be focused on the study of gas flow dynamics, concentration polarization in a membrane module by employing computational fluid dynamics. Research objectives are
• Optimization of membrane module geometry. • Development of a 2D/3D mass transfer model for gas separation by hollow fiber modules.
• Investigate the model results for desired gas concentrations.
• Investigate the CFD results for different flow conditions.
• Study the flow distribution/patterns in hollow fiber membrane modules.
• The mass transfer model will be applied for various
• • •
conditions, focusing on axial and radial diffusion/ dispersion in the tube and shell sides of the hollow fibers. The modeling results will be validated with experimental data. CFD approach will be used to predict concentration polarization in hollow fiber modules. Analysis of design/operating parameters that affect separation performance of the modules.

CO2 capture from Natural and Flue gases using Polymeric membranes Name: : Sarah Farrukh
Supervisor: Dr. Arshad Hussain
Membrane-separation technology has evolved as a rapidly growing field during the past few decades, and it has been approved economically and technically as a favorable and competent separation process compared to the other separation techniques in use because membrane technology offers numerous advantages over other technologies, including a low energy requirement, smaller footprint, low capital and operation costs, environmental friendliness and flexibility in handling at higher flow rate, pressure, and various feed compositions. Membrane gas separation, a relatively young technology, has emerged in the last 15 years to successfully compete with other wellestablished industrial gas-separation processes, such as cryogenic distillation, absorption, and pressure swing adsorption. Membrane gas separation (MGS) is the pressure driven process with different industrial applications and represent only a small fraction of potential applications in refineries and chemical industries. With the serial production of commercial polymeric membranes since 1980, MGS has rapidly become a competitive separation technology. Up until now the commercial membranes material for gas separation has basically been polymers like poly imides, polyamides and cellulose acetates. All these membranes have good permeability for carbon dioxide, but lack in selectivity or vice versa. Gas separation membranes are based on Solution-Diffusion model. These membranes are non-porous. Gas separation membranes follow the Fick’s Law of Diffusion (see in Fig 1), written in modified form as equation 1.
In the view of above, there is a need to synthesize polymeric membranes which can capture CO2 with high permeability and selectivity. The objectives of my research work are given below. • The proposed research will help in developing new polymeric membranes and establish new experimental facility to investigate membrane based gas separation processes. • Different polymeric materials will be investigated to identify the suitable material / compositions / additives for gas separation membranes. • Polymeric membranes for both; Post combustion (CO2 capture from flue gases) and Pre -combustion (CO2 capture from Natural gas) application would be developed. • The successful completion of this work will persuade the process industry to employ membrane based CO2 capture technology to reduce the CO2 emissions. The ICI Pakistan has already shown its interest in the proposed research. • The proposed research work and new experimental facility will help to train the students/researchers and impart the knowledge of membrane based gas separation process. • SCME, NUST will have a dedicated experimental facility on membrane based gas separation. The success of this research project will not only provide an excellent research facility in this scientific area but also contribute in enhancement of fuel efficiency and prevention of global warming.

Synthesis of Chiral Bidentate Ligands and Their Applications in Combinatorial Asymmetric Catalysis Name: Tariq Zaman
Supervisor: Dr. Habib Nasir
Enhanced effectiveness of pharmaceuticals and agrochemicals is the most sought-after attribute in the field of enantioselective synthesis of chiral molecules where single enantiomer (R or S) is required, for which asymmetric catalysis is an attractive way.
Â
The synthesis of enantiomerically pure compounds in traditional way is difficult, costly and time-consuming process involving the running of long columns which create a lot of waste that causes water pollution. The selectivity of products are equally depends upon the catalyst and conditions of the reaction which makes the task harder for selecting and finding new catalytic system.
Â
Present work deals with the development of five families of chiral ligands libraries for rapid recognition of the best system, by using combinatorial chemistry, during hydrogenation of ketones, a starting material and as intermediate in a number of processes. The ligands were both generated in situ and in pure form for the comparison of results and were obtained by simple condensation, providing one of the starting materials being chiral. Five families namely; bisimine, amine, aminal, imine and oxazoline were synthesized and tested in presence of Zn(II), Rh(I) and Rh(III) by using polymethylhydrosiloxane (PMHS) and diphenylsilane for hydrosilylation and aqueous media for transfer hydrogenation during synthesis of selective chiral alcohols from achiral acetophenone. Overall 1566 catalytic systems were tested and the yield and enantiomeric excesses were found by using 1H NMR and chiral chromatography respectively with more than 90% ee and 99% conversion as the best result for imine ligands. It has been proven that ligands synthesized in-situ gave comparable and almost same results to purified version with best reproducibility.

Molybdenum disilicide coating on Molybdenum substrate Name: : Fahad Zafar
Despite being a high melting metal with good mechanical properties the use of Molybdenum at high temperatures is limited due to its poor oxidation resistance above nearly 600°C.Therefore the use of Molybdenum in high temperature ranges is only possible after application of some suitable protective oxidation resistant coating. Such a coating aspires forming a self-healing protective oxide layer, thus preventing direct atmospheric contact with the substrate. Many coating have been applied onto Molybdenum alloys to provide oxidation resistance including Au, Ni, Cr, Al-Si etc. Among the various coatings applied onto Mo alloys, silicide coatings had proven outstanding for high temperatures. At temperatures above 1000°C, the formation of stable glassy silica scale accounts for the oxidation resistance of Molybdenum substrate. Such silica

Fabrication of Ultra Filtration membranes and its application for water hardness quality Name: : Adnan Alam
Modern world is facing adverse environmental problems. Removal of toxic components from industrial effluents, good quality water for domestic and industrial use, pharmaceutical industry and food industry requires efficient and low cost evaluation techniques. Use of membranes for isolation, concentration and purification has great deal of significance. Membrane technology has been widely used worldwide for separation of mixtures, isolation of desired components. Due to energy efficiency and accuracy, ease of use and environment friendly response, Membrane technology has flourished rapidly since 1960. Membrane processes like microfiltration (MF), Ultra filtration (UF), Nano filtration (NF) and Reverse osmosis (RO) have been successfully used at industrial scale for recycling, cleaning and concentration. Among these processes, Ultra filtration is significant for separation and concentration of macromolecular solutions and colloidal solutions. Molecules of similar sizes cannot be separated by UF. Ultra filtration membranes work under selective pressure. It allows the smaller solute molecules and sol-
Supervisor: Dr. Mohammad Mujahid vent molecule to pass through while retains the larger molecules. For this purpose organic polymer “Cellulose acetate� has significant effects as membrane. CA membranes in ultra filtration have valuable advantage that it performs two tasks in one step i.e. separation and concentration. Further, the performance of membrane is mainly dependent on the pore size. During phase inversion technique, the pore former play key role. It could be solid particle or solvent molecule, but its polarity must be different from the solvent, so that it has negative effect on polymer dissolution. Owing to better results than conventional methods, UF membranes were prepared and quality of water hardness was improved. In UF membrane Cellulose acetate (CA), being the matrix material, the variation in concentration of Chitosen(CS) was the key to control porosity in the membranes. Hence in the present investigation, cellulose acetate was blended with different concentration of Chitosan in formic acid and the results are studied.
SEM results shows membrane porosity is orderly increasing from sample A to F

A new class of materials which exhibit negative Poisson’s ratio is known as Auxetic Materials. These materials antithetical to conventional materials for example rubber and metals etc. get fatter when pulled and contract transversely when pushed longitudinally. Other properties of auxetic materials that have shown enhancement are indentation resistance, thermal shock resistance, acoustic damping properties and fracture toughness. Auxetic materials possess potential applications in sensors, biomedicine, auxetic fibre reinforced plastics, smart textile, bullet proof vests and helmets, and filters. Auxetic materials research has now reached the phase where a

There are as many diverse manufacturing routes, for the preparation of auxetic materials, as there are materials.

The foam was then converted into auxetic material through a procedure involving volumetric compression, heating further than the polymer’s softening temperature and then cooling at the same time as remaining under compression.

Lowering of Band Gap of Titania Thin Films by Integration of Graphene Nanosheets Name: Haroon Mahmood
Titania possesses a band gap of 3.2 eV, while work function of graphene 4.5 eV exists near LUMO of titania. The photoexcition of electrons in titania is only possible under ultraviolet radiations. In order to obtain such conversion in visible light range, band gap has to be lowered below 3.1 eV. This research work aims at lowering the band gap of titania thin films by incorporation of graphene nanosheets. Graphene was synthesized using modified Hummer’s method in which graphite flakes were oxidized using KMnO4 in an acidic solution. After washing of graphite oxide, exfoliation was carried out by sonication of graphite oxide dispersion, producing graphene oxide. Reduction of graphene oxide nanosheets was carried out by treating it with hydrazine hydrate resulting in reduced graphene oxide. Oxidation of graphite was confirmed by XRD revealing a peak at 11.8° with interplanar distance of 7.5 Å and EDS analysis showed almost complete oxygenation of carbon. AFM analysis revealed exfoliation of single layer graphene oxide nanosheets having thickness of 0.6 – 1.0 nm. FT-IR analysis confirmed reduction of graphene oxide by revealing removal of carbonyl group (C=O). Titania sol was produced using hydrolysis and condensation of titanium tetraisopropoxide in aqueous acidic
Supervisor: Dr. Amir Habib solution containing glacial acetic acid and hydrochloric acid. The TiO2-graphene composite was prepared by two routes. In one method, liquid phase dispersion of graphene oxide was added in titania sol and reduction of deposited films was done by exposing hydrazine hydrate vapors. In second method, nanoparticles of reduced graphene oxide were dispersed in titania sol and thin films were fabricated subsequently. Thin film fabrication was carried out using spin coating. Every film deposited was dried at 80°C for 5 min and annealed at 450°C for 50 min at a heating rate of 2°C min-1. TiO2-graphene films characterized using SEM, revealed homogenous dispersion of graphene nanosheets among homogenously distributed titania nanoparticles of uniform size distribution (~ 30-50 nm). Surface roughness of about 16 nm was observed by AFM topographic images. The HOMO/LUMO levels were calculated by cyclic voltammetry and subsequent band gap was calculated which came out to be as low as 2.9 eV. Ti-O-C chemical bonding between titania and graphene sheets resulted in enhanced electron transport in the obtained composite films. These results favor the use of such films in Inverted Organic PVs as electron collecting layer and active layer in normal OPVs.

Synthesis of Aluminum, Teflon & Viton (ATV) Pyrotechnic Compositions Name: Muhammad Aamer
Aluminum and Teflon based composition are widely used in IR decoy flares formulation because of their large energy output compared to other pyrotechnic mixture, low hygroscopicity, low dependence of burning rate on pressure and temperatures, and relatively high degree of safety in preparation. Viton (binder) is commonly added to AT mixture for easy processing by improving homogeneity of mixture and also protect aluminum against oxidation by moisture during storage. This work focuses on the synthesis characterization and thermal analysis of ATV composition. We have employed shock gel synthesis method using auto-clave at about 3500 kPa and 2000C with continuous stirring and continuous supply of liquid CO2. The main advantage of this procedure is that it ATV composition energetic material can be syn-

Supervisor: Dr. Habib Nasir
In the present work magnesium oxide nanoparticles were synthesized successfully by modified sonochemical method. Magnesiumnitrate hexahydrate Mg(NO3)2.6H2O and NaOH were used as the precursor materials with distilled water as a solvent. PVP was used as structure director to prevent agglomeration and control morphology of nanoparticle. Different concentrations of precursors were used to check their effect on size and morphology of particles. The Mg(OH)2 nanoparticles obtained from this method were calcined at 500 0C in order to get
MgO nanoparticles. All the samples were characterized by Fourier transform infrared spectroscopy (FTIR), UVvisible spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), AFM, BET and TGA-DTA. Results showed that particle size and surface area of MgO nanoparticles are pH sensitive. The XRD spectra indicated that the synthesized nanocrystalline MgO has a cubic structure. SEM images were accorded with the AFM and XRD data showing that the average sizes of the particles were in the range of nanometer.

Improvement in the Mechanical Properties of Rubber Composite by Doping of Nanoparticles Name: Sadaf Bashir Khan
Research on nano-composite having polymeric matrix containing nanoparticles is a new area of research in material science. Magnetic Nano-composites fascinate because of their extensive application in technologies, such as electromagnetic interference shielding (EMI), drug delivery, bioprocessing, medical diagnosis, ferrofluids, and drug targeting. For this purpose, different magnetic particles are used in combination each having its own importance and distinctive physical and chemical properties, which enhance the properties of composites. Research scholars at SCME-NUST in Thermal Transport lab have been working on the application of ferrites in technological material applications.One such work has been done by synthesizing nickel zinc ferrites at nanoscale in order to improve the mechanical properties of composites by doping of nanoparticles in polymer matrix. Different methods are used to synthesize nano particles but in this research, co-precipitation method is used to synthesize nickel zinc ferrites nanoparticles as it controls

Supervisor: Prof. Dr. Asghari Maqsood particle size, degree of agglomeration and chemical homogeneity. These nanoparticles are then functionalized by APTMS abbrivated as (3-aminopropyl)-trimethoxysilane also known as silane coupling agent. Nanoparticles are functionalized due to the following two reasons. It makes strong covalent bond between matrix and filler and improves the strength and mechanical properties of the composite. These functionalized nano composites then are dispersed in Poly dimethyl siloxane (PDMS) through ultra-sonication and mechanical stirring. SEM results shows that nanoferrites are homogenously dispersed in PDMS. PDMS is optically clear, inert, non-toxic, and non-flammable polymer. In the present research, filler loadings of same weight but various compositions are used. Composite having nickel and zinc ferrite nanoparticles in (1:1) shows the best tensile strength and good compressive strength.Using Scanning Electron Microscope, it was found that the size of nanoparticles embedded in the polymer matrix is(30 –50 nm) as shown in the following figures

Improved Carbon-Based Sorbent for CO2 Capture Name: Maha Yusuf
Carbon Capture and Storage (CCS) technology is relatively a new concept and has recently drawn great attention owing to the contribution of fossil fuel emissions to global warming and climate change. The idea behind the technology is to capture waste carbon dioxide (CO2) from large sources such as fossil fuel power plants or even the very atmosphere and store it to such sites where it will not be able to enter the atmosphere. For this purpose, advanced CO2 sorbents are being synthesized across the globe and research is very active. The use of such sorbents is not just limited to mitigating climate change but can also be used for industrial applications for example, replacing liquid amine as a CO2 capture adsorbent in
Supervisor: Prof. Dr. Habib Nasir industry. In our work, we are proposing new methods for developing an advanced carbon-based sorbent for CO2 capture, making use of nano-graphene as the base material. Nano Graphite is converted to Nano Graphene Oxide (NGOs) via a new Hummer’s method’ yielding higher The NGOoxidationisthenconverted tolevelsNGO wit framework which is then, functionalized by ethylene diamine (EDA) for increasing the carbon adsorption capacity. Characterization techniques like BET with CO2 is used for compiling CO2 capture data, XRD for determining the crystallinity of the intermediates and SEM - EDAX for elemental composition in the samples made.

Hydrogen Production by Al-H2O Reaction in Presence of Chlorides Name: Safdar Hayat
Energy plays very important role in present era of industry, society and transportation. Almost every country is facing or expecting to face an energy shortfall in near future. Pakistan having a large number of rivers and abundant water flowing across the country, a nuclear state, vast open lands for wind/solar energy and large reservoirs of coal may generate enough energy to meet its present requirements but in future Pakistan must be looking for alternative sources of clean energy. Presently large portion of energy is mainly produced by oil, gas and coal and very less portion is derived from renewable sources. Rapidly decreasing, exhaustion of fuel reservoirs and environmental concerns are major factors towards the use of renewable clean energy. The use of hydrogen to generate energy is an interesting approach because of the
42
Supervisor: Prof. Dr. Habib Nasir salient features of this gas. Metal Aluminum, not only the most abundant metal in the earth’s crust but also is a potential and promising candidate for hydrogen production from water because of its electrochemical properties. In addition, the metal consumption is identified to be an efficient, user-friendly, and harmless approach for hydrogen production. Hydrogen is often considered as clean fuel but its greenhouse clean effect mainly depends on the method of hydrogen production. If it is produced in the same conventional manner by use of coal or fossil fuel, we cannot pronounce hydrogen as clean fuel because the CO2 emission has already taken place. So the process of hydrogen production is more important and should be a clean method of production.

Glorious Graphene Mohammad Yousuf Mehmood
Batch Che 05
Smart-phones, tablets and laptops are all the rage these days, with new variants emerging every few months or sooner. Equipped with the latest hardware and cutting edge software, these machines easily outperform even the super computers of as late as a decade ago. More storage, better battery life, faster processors and most importantly a thinner package for all of that is essential for every new model that goes on sale. Behind all of this is incredible innovation and precise engineering. Those of you who have watched Apple’s or Microsoft’s keynotes probably know what I’m talking about. However we’re coming to a tipping point, that is, sooner or later this progress in speeds and increase in storage will slow down, and according to some estimates, will stop completely. Every year the computer industry manufactures smaller and smaller transistors to increase the computing power of processors (smaller transistors mean more transistors in a processor chip which in turn means more calculations can be done and faster than the previous processor). This is why Intel comes up with a faster line of processors every year (Core 2 Duo, i5, i7 etc). Similarly batteries are made more efficient by figuring out how to store more energy per area. But this can’t go on forever. After all, this process is simply squeezing more information into smaller and smaller space. Space has to run out some time. That is unless the method to store information is altered. In 2010 the Nobel Prize for Physics went to Andre Geim and Konstantin Novoselov from the University of Manchester for their “groundbreaking” experiments on the two dimensional material, graphene. Graphene is a single atom thick layer of hexagonally shaped carbon rings. Graphene seems to be the savior of the computer chip industry. Up until recently the com-
puter industry had been making computer chips out of silicon, but its capacity to evolve in to a faster processor every year is running out. Graphene, a newly discovered allotrope of carbon will be able to solve this problem, simply because its structure allows for faster transistors to be manufactured. In 2011 IBM unveiled a graphene transistor able to function at an incredible speed of 155GHz. Go home and check the speed of your computer processor and notice the difference. If that wasn’t enough, graphene is proving to be a Super, supercapacitor. Richard B. Kaner, a chemist from the California Institute of Polymers discovered that if he charged a graphene strip for just a few seconds, he could power an LED for over five minutes. This, if implemented on a large scale could mean instant charging for cell phone, tablet, laptop and even electric car batteries. Imagine running out of battery power just when you need to make a phone call and plugging in your phone for a few minutes, and being at full power again. That is achievable in the near future. Graphene has been dubbed the “Wonder Material” and rightly so. Like the discovery of any new material, the advent of graphene holds amazing new applications and inventions and promises to revolutionize the industry and usher in a new era of not just energy efficiency, but clean energy. Why? Because graphene is pure carbon, when you’re done with it as a battery or a computer chip you can recycle it without any harmful by products. It’s amazing that the same element that makes up coal makes up diamonds, the graphite in your pencil and will very soon make up the batteries and processors in the computers you use every day. Yeah you read correctly, all those things are pure carbon. 49

Engineering Conundrums #1
Powering the Biggest Dam in the World Muhammad Hassaan Munir
Batch Che 05
Hydropower has been a veritable source of electricity since Lord Armstrong engineered a 4 Kilowattsdomestic dam in Northern England in late 1878. Since Armstrong’s invention, numerous dams have sprung up around the world because of the clean and cheap electricity they generate while providing flood-management and reservoir capabilities. Not to mention, they have evolved continually – getting more complex in design and having generation capacities of thousands of Megawatts. Without doubt, the pinnacle of dam construction was attained with therecent inauguration of the Three Gorges Dam in China. Rising from the depths of the mighty Yangtze River, it is the largest dam in the world. The Three Gorges Dam rises to a colossal 60 stories and is 2 kilometers wide. This exquisite engineering feat is also the biggest concrete structure on the planet with a whopping peak generation capacity of 22,500 Megawatts, which roughly equals the amount of electricity generated by Pakistan& UAE combined! Constructed in a period of 17 years by a workforce of over 40,000, it had to deal with a plethora of problems. Including flood alarms, the exothermic effect of 27million cubic meters of concrete or dealing with shipcrossings in the busiest river in China. The project engineers passed these tests with flying colors until a bigger

problem surfaced. The Three Gorges dam has 32 generators with a single generator costing $50 million. Each of these generators is connected to a total of 48 governor pumps. These rotary pumps have to pump hydraulic oil to the heavy flood gates of the dam to control water inlet to the turbines that in turn power the generators. These pumps have to operate, without reprieve, 365-days-a-year. This calls for paramount quality and durability. So, a top pump firm, Acorax Enterprises, was called in and they had to deal with a unique phenomenon at the Three Gorges – varying outlet pressure. It is relatively easier to design components under steady pressure. During variations, however, pressure on the various components is extremely difficult to predict and handle. In addition to damaging the pump’s casing, frequent changes in pressure lead to the destruction of rotating parts of the pump
SCME / Annual / Star Magazine as well. Also centrifugal pumps, which can handle pressure changes very well, could not be used here as the liquid being pumped is viscous which would have led to decreased flow rate and foaming because of turbulence. The firm had to stick with rotary pumps and they had to design them to acclimatize to fluctuating pressure differences. After a month of hard work, they claimed to have design the perfect governor pump for the Three Gorges. A test run was conducted with a single turbine. The pump started well, project heads were impressed and then after a mere four hours of service the pump burst. Thanks to the rapid action of the onsite workers, any damage to the expensive turbines was avoided but the pumpcompany was sent packing. After this initial setback, the Three Gorges Enterprises
of the governor pumps. The pumps they installed at the Three Gorges site are the triple-screw SMH1300. These screw pumps are positive displacement pumps that displace a fluid across the spindles on the screw’s axes. A triple screw pump, as evident from the name, has three screws to it. There is a rotating central screw, which is sandwiched between two auxiliary screws. As the central screw moves, it induces counter-rotations in the other screws, i.e., the other screws move in opposite direction. This movement allows the liquid to move along the spindles of the screws with minimum turbulence while also being compressed. Rotary screw pumps are an industry mainstay when it comes to hydraulic applications and they are working seamlessly at the Three Gorges since 2004.
knocked on the door of the Germany-based, Allweiler Corporation. They managed to design pumps that took into account the water level variations in the dam reservoir and thus dealt with the fluctuations in discharge pressure
Standing on the shoulders of historic engineering, the Three Gorges Dam is the ultimate hydroelectric dam in the world. That is, until someone builds and even bigger one.
