For innovative research in nuclear structure physics, particularly in areas leading to a quantitative understanding of the excitation and decay of the elementary collective modes of nuclei, and for vision and scientific and technical leadership in building the Holifield Radioactive Ion Beam Facility into a forefront laboratory for nuclear science.
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.
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.
