Prior to joining MSE in July 2003 Professor Singh was a faculty member in Corrosion and Materials Engineering Group at The Institute of Paper Science and Technology (IPST) since 1996.  While in IPST Singh worked on fundamental as well as applied research projects related to the corrosion problems in the pulp and paper industry. From 1990 to 1996, he was a Senior Research Associate at Case Western Reserve University, Cleveland, Ohio, working on various materials and corrosion related research projects, including damage accumulation in metal matrix composites (MMCs), Environmental sensitive fracture of Al-alloys MMCs, and High temperature oxidation of Nb/Nb5Si3 composites. He received the Alcan International's Fellowship in 1988-90 to work on "Effects of Low Melting Point Impurities on Slow Crack Growth in Al Alloys,"  He has published over 50 papers in reputed scientific journals and conference proceedings. He is active member of NACE, TMS, TAPPI and has co-organized a number of international symposiums.

Reliable performance of the materials is very important for any industrial process and especially for the chemical process industry for the manufacture of a high quality product. Material selection is generally based on the required material properties, low initial capital investment, and minimum maintenance. Changes in the process parameters to improve products can often lead to higher corrosion susceptibilities of the plant materials. Moreover, with increase in capital cost, there is pressure to extend the life of existing plant equipment beyond its original design life. Corrosion and Materials Engineers are also playing a key role in selecting, maintaining, and modifying materials for changing needs for every industry. Corrosion Science and Engineering research includes understanding the basic mechanisms involved in material degradation in given environments and using that knowledge to develop a mitigation strategy against environment-induced failures

Carsten Sievers

Carsten Sievers
carsten.sievers@chbe.gatech.edu

Sievers’ research interests are in heterogeneous catalysis, reactor design, applied spectroscopy, and characterization and synthesis of solid materials. Combining these interests he seeks to develop processes for the production of fuels and chemicals. His research program combines fundamental and applied research.

In fundamental studies, a suite of analytical and spectroscopic techniques (e.g. IR, NMR) is used to gain knowledge on structure-reactivity relationships of heterogeneous catalysts. Moreover, surface reactions are studied on a molecular level to identify reaction pathways over different catalysts. Information obtained from these studies provides the foundation for designing innovative catalysts.

Applied studies focus specific catalytic processes. For these projects, continuously operated flow reactor systems are designed. Different catalysts are tested for reactivity, selectivity and stability and the influence of the operating conditions is investigated. Catalyst deactivation is studied in detail to develop suitable regeneration methods or to avoid deactivation entirely by improved catalyst design. Specific projects include hydrodeoxygenation of pyrolysis oils, selective hydration of polyols, conversion of sugars into lactic acid and ethylene glycol, and selective oxidation of methane.

An important goal of Sievers’ research is to enable technology for utilization of alternative resources in order to reduce the current dependence of oil. Among these biomass is a particularly promising candidate because it is renewable and can be produced CO2 neutral.

Sievers has contributed to 80 peer reviewed publications on heterogeneous catalysis in petroleum refining (isobutane/2-butene alkylation, fluid catalytic cracking, hydrotreating), alkane activation, supported ionic liquid as catalysts for fine chemical synthesis, and biomass processing.  He is Director and Past President of the Southeastern Catalysis Society, former Program Chair and Director of the ACS Division of Catalysis Technology & Engineering, former Director of the AIChE Division of Catalysis and Reaction Engineering, and Editor of Applied Catalysis A: General.

Paul S. Russo is a Professor of Materials Science and Engineering with a joint appointment in the School of Chemistry and Biochemistry at the Georgia Institute of Technology with expertise in polymer, biopolymer and particle chemistry.

His research interests are rooted in rodlike polymers, such as plant viruses, cellulose derivatives and aromatic backbone materials. Particular emphasis has been paid to molecular transport in complex fluids containing rods and to related measurement methods. Static and dynamic laser light scattering have been joined by fluorescence photobleaching recovery and pulsed field gradient NMR spectroscopy to measure diffusion in dilute and concentrated solutions, gels, and liquid crystals. Dialysis implementations of these techniques have permitted stability studies of the amyloid protein responsible for Alzheimer’s disease. Other materials of interest include organophilic polypeptides, which have been coupled to silica cores to yield hybrid particles that can carry hydrophobic payloads, such as enzymes. The same particles can also form colloidal crystals and linear arrays. Small-angle x-ray scattering plays a role in the characterization of these materials. Hydrophobic proteins are being used to template the synthesis of polymers in new and unusual shapes and to disperse oil following marine spills.
