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 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.
For basic studies in the fracture of and toughening mechanisms in ceramics and ceramic composites, in the establishment of the relationships between microstructure and composition and mechanical behavior, and in the development of advanced ceramic materials.
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.
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."
