Researchers Discover the Cause of Irradiation-induced Instability in Materials Surfaces
April 12, 2011
A new discovery about the dynamic impact of individual energetic particles into a solid surface improves our ability to predict surface stability or instability of materials under irradiation over time. The finding may lead to the design of improved structural materials for nuclear fission and fusion power plants, which must withstand constant irradiation over decades. It may also accelerate the advent of fusion power, which does not produce radioactivity.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
