For significant and fundamental achievements in laser-based chemical measurement techniques, such as single molecule detection in liquids, and pioneering the efforts in the development of microfabricated chemical instrumentation, including the laboratory on a chip concept.
Greenbaum, the winner of the 1995 DOE Biological and Chemical Technologies Research Award, has done extensive experimental work in photosynthesis, the process by which green plants grow, and its application to renewable energy production.
For ideas and techniques which have opened new frontiers in chemical research and now play major roles in the study, understanding, and use of photoionization and photoelectron spectroscopy in studies of "hot atom" chemistry and work with multiply charged molecular ions.
For pioneering work on energy conservation, including development of energy demand models, data bases, and analyses of energy use trends, which has contributed to federal and state energy policies and programs and to demand-side planning by electric utilities.
Mazur, who led the Theoretical and Applied Cryobiology Group in the Biology Division, concentrated his research on fundamental mechanisms responsible for injury to cells during freezing and warming. This research and other basic findings were described in his review paper "Freezing of Living Cells: Mechanisms and Implications."
For theoretical research on the electronic and vibronic structures and optical properties of defects in ionic crystals, and for work at the forefront of the rapidly developing field of laser annealing of semiconductors, leading to advances in the photovoltaic conversion of solar energy.
