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 significant advancement of welding science and technology through original and definitive research, particularly for contributions to understanding the solidification behavior of the weld pool, phase stability microstructure-property correlations in welds, and continued leadership and outstanding service to the national and international welding research community.
For contributions to understanding plasma turbulence and the nonlinear properties of magnetohydrodynamic instabilities, especially their role in explaining the behavior of magnetically confined plasmas, and for development of new magnetic confinement concepts that overcome these limitations.
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.
