When A Good Nanoparticle Goes Bad

NSF News  Mon, 11/10/2008 - 11:00

Clues found in nanoparticles may help solve global energy challenge.

Researchers at Cornell University recently made a major breakthrough when they invented a method to test and demonstrate a long-held hypothesis that some very, very small metal particles work much better than others in various chemical processes such as converting chemical energy to electricity in fuel cells or reducing automobile pollution.

(Cornell University Communications) A field of fuel dreams: Cornell bioenergy plant experts are learning which field grasses are the best candidates for "dedicated energy" crops in the Northeast, considering the region's climate and soil conditions.


 

Researchers show how to 'stamp' nanodevices with rubber molds

EurekAlert! - Chemistry, Physics and Materials Sciences  Tue, 10/21/2008 - 23:00

(Cornell University Communications) By manipulating the way tiny droplets of fluid dry, Cornell researchers have created an innovative way to make and pattern nanoscale wires and other devices that ordinarily can be made only with expensive lithographic tools.

The process is guided by molds that "stamp" the desired structures.

(Cornell University Communications) Could a computer model help stabilize the tuna population? Can we compute how to transition to ethanol fuel without jeopardizing food production?Those and other questions will be tackled by computer scientists, applied mathematicians, economists, biologists and environmental scientists affiliated with Cornell University's new Institute for Computational Sustainability, being launched with a $10 million grant from the National Science Foundation.

Scientists at Brookhaven Lab, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors — the temperature at which these materials carry electrical current with no resistance — cannot simply be elevated by increasing the electrons’ binding energy.


 

Free articles get read but don't generate more citations

EurekAlert! - Mathematics and Statistics  Wed, 07/30/2008 - 23:00

(Cornell University Communications) When academic articles are "open access" or free online, they get read more often, but they don't -- going against conventional wisdom -- get cited more often in academic literature, finds a new Cornell study.
