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 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 application of chemical and engineering principles to the development of nuclear fuel processing; separation science and technology; and innovative biomedical and bioprocessing concepts for environmental protection, energy production and conservation, and resource recovery
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 contributions to the development of new concepts and advanced systems for power generation and conversion, through innovative designs of nuclear reactors for aircraft propulsion and space auxiliary power and concepts for thermonuclear fusion reactor power plants
