 Research and Expertise
Heterogeneous Catalysis
 
Current studies include detailed mechanistic and kinetic investigations of the conversions of selected compounds over shape selective catalysts. The major effort at present is concentrated on the reactions of low molecular weight halocarbons as catalyzed by zeolites, specifically ZSM-5. The shape selectivity of the product formation observed will be contrasted with that obtained from unhalogenated hydrocarbons. Isotopic labeling and substituent effects are being investigated to provide mechanistic details of these important reactions. Future studies will involve the extension of these investigations to a broader range of heteroatoms containing organic compounds including phosphorus and sulfur containing molecules.
Plasma Chemistry
 
In this work, we employ plasma deposition methods to obtain controlled surface modifications for a variety of materials. The goal of this research is to provide molecular level tailoring of surfaces for specific applications. Significant success in this endeavor has been achieved through use of a variable duty cycle pulsed RF plasma technique developed in our laboratory. In particular, we have been able to demonstrate exceptional film chemistry control during plasma polymerization of a wide range of monomers. Emphasis is placed on controlling both the nature and surface density of specific functional groups introduced during the plasma treatment process. These surfaces can subsequently be treated by more conventional chemical derivatization processes to produce 3-dimensionally molecularly engineered structures. There is a wide range of potential applications for the pulsed plasma treatment processes we have developed. At present the major applications effort is devoted to improving the biocompatability of implant materials. Future studies will include work in catalysis and the development of improved membranes for separation processes

 Teaching
 
CHEM 1465-001 - Chemistry For Engineers
Summer II 5-week 2009
An introduction to important concepts and principles of chemistry with emphasis on areas considered most relevant in an engineering context. Topics include chemical stoichiometry, bonding, chemical thermodynamics, equilibria, electrochemistry, and kinetics. Engineering students may substitute the eight hour sequence CHEM 1441 and CHEM 1442 for this class, but not either CHEM 1441 or 1442 alone. Students who complete CHEM 1465 and subsequently change majors to curricula that require both CHEM 1441 and CHEM 1442 may substitute CHEM 1465  for CHEM 1441. Prerequisite: high school chemistry and MATH 1323 or concurrent enrollment.
