Materials Chemistry Team

The Materials Chemistry Team consists of three Ph.D researchers, a technician and varying numbers of Postdoctoral Fellows and Graduate Research Assistants. Our research interests are materials for solid state energy conversion applications and solid state chemical sensors for a variety applications. We are also engaged in research in the fields of oxide thin film science, ion transport in solids, gas separation membranes, fuel cell and hydrogen storage materials research and oxide materials chemistry.

The MC Team specializes in complex impedance analysis of ion transport in solids, thin deposition and characterization  of ion conducting materials, modern X-ray analysis methods including whole pattern X-ray diffraction analysis, the chemical imaging of surfaces and the measurement of thermodynamic properties of materials for energy conversion.

Our wealth of experience with polymer electrolyte membranes puts us in a unique position to apply this expertise to the development of hand-held chemical warfare agent detectors. These sensors will be valuable in remote detection systems for buildings, tunnels, laboratories, and public spaces, as well as in portable detection systems like those needed by first-responders to emergency situations. Our chemical detection system uses the MEA to foster an electron transfer reaction triggered by the presence of certain chemical agents. For more information on this area of research, click here.

Our research facilities include a high temperature chemistry laboratory, scanning electron microscopy coupled to energy dispersive X-ray analysis, gas chromatography, mass spectroscopy, electron beam evaporators, R.F. magnetron sputtering systems, ion mill, high resolution X-ray diffraction equipment, X-ray fluorescence spectroscopy, differential scanning calorimetry, thermal gravimetric analysis, solution calorimetry, AC impedance spectroscopy, DC voltammetry, and a BET surface area measurement apparatus.

Team Members: Fernando Garzon (Team Leader), Eric Brosha, Jerzy Chlistunoff, Roger Lujan, Rangachary Mukundan, Tommy Rockward, Francisco Uribe, and Calita Quesada.
