For significant contributions and leadership in the processing and properties of materials, particularly intermetallic alloys, which have led to his reputation as one of the world's leading scientists in these areas.
For distinguished research on the air/surface exchange of atmospheric trace gases and particles and their interactions with the Earth's biogeochemical cycles, and for pioneering developments in atmospheric sampling methodologies with special emphasis on the global mercury cycle.
For fundamental studies of the microscopic structure of magnetic materials using neutron scattering methods, and for contributing to the development of neutron polarization analysis as a productive scientific technique.
For fundamental studies in radiation physics and dosimetry, in research to link the basic physics and chemistry of biological molecules irradiated in aqueous solution, and the physicochemical characterization of chemical pollutants
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.
