A Supra New Kind of Froth
June 6, 2008
Who would think that the froth on a morning cup of cappuccino has a lot in common with superconductors? A team of U.S. Department of Energy's Ames Laboratory physicists have found that the bubble-like arrangement of magnetic domains in superconducting lead exhibits patterns that are very similar to everyday froths like milk on a fancy coffee. The similarities between "suprafroths" and conventional froths establish suprafroths as a model system for the study of all froths.
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) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
