Nanotube Flickering Reveals Single-Molecule Rendezvous
June 7, 2007
In this week's issue of the journal Science, French and U.S. researchers describe a new technique that allowed them to zoom in and observe quantum quasiparticles called excitons on individual carbon nanotubes. The team, which was led by Rice University chemist Bruce Weisman and University of Bordeaux physicist Laurent Cognet, found that each exciton travels about 90 nanometers and visits around 10,000 carbon atoms during its 100-trillionth-of-a-second lifespan.
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.
