Zeroing In On Quantum Effects
May 28, 2010
U.S. and Chinese physicists are zeroing in on critical effects at the heart of the newest high-temperature superconductors, the family of iron-based compounds called "pnictides." Research in this week's Physical Review Letters describes a Rice University-led study that used similarly structured materials called "oxychalcogenides" to investigate the effect of expanding the distance between iron atoms in the crystal lattice.
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) 2014, its budget is $7.2 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
