研究领域

Students working in my laboratory are developing new chemical analysis methods and instrumentation required to study problems which are particularly relevant to present day society. Current research efforts focus on novel applications of chromatography, Fourier transform infrared spectroscopy (FTIR), and mass spectrometry. Emphasis is placed on combining complementary analysis methods to produce "hyphenated" analytical systems. These new analytical tools have been found to be very useful in material science and forensic research. Previous applications have focused on probing surface reactions in heterogeneous catalysis, polymer structure characterizations, in particular studies of the influence of metal substrates on the accelerated degradation of paint binders, elucidation of non-oxidative ceramic sintering processes used in the microelectronics industry, and development of new approaches for recycling waste plastics that result in production of valuable hydrocarbon solvents. Our current research involves the use of a novel, custom built fast gas chromatography apparatus for rapid separation and quantification of residual solvents in pharmaceutical preparations and evaluation of new processes designed for conversion of biomass to fuels. The latter project involves studies based on the use of acid catalysts and ionic liquid solvents that can be easily recycled, resulting in a new fuel production process that is both efficient and environmentally friendly. While pursuing these research goals, we are continually striving to improve our analytical instruments and methodologies to add new capabilities to our chemical analysis toolkit.
