Rutgers physicist elected to American Academy of Arts and Sciences
29-04-2013
Rutgers University physicist Karin Rabe has been elected to membership in the American Academy of Arts and Sciences, one of the nation's most prestigious honorary societies and a leading center for independent policy research. Rabe is a professor II in the Department of Physics and Astronomy ...
Researchers pinpoint how trees play role in smog production
29-04-2013
After years of scientific uncertainty and speculation, researchers at the University of North Carolina at Chapel Hill show exactly how trees help create one of society's predominant environmental and health concerns: air pollution. It has long been known that trees produce and emit isoprene, ...
Vaterite: Crystal within a crystal helps resolve an old puzzle
29-04-2013
With the help of a solitary sea squirt, scientists have resolved the longstanding puzzle of the crystal structure of vaterite, an enigmatic geologic mineral and biomineral. A form of calcium carbonate, vaterite can be found in Portland cement. Its quick transformation into other more stable ...
Keeping beverages cool in summer
It's not just the heat, it's the humidity
29-04-2013
In spring a person's thoughts turn to important matters, like how best to keep your drink cold on a hot day. Though this quest is probably as old as civilization, University of Washington climate scientists have provided new insight. It turns out that in sultry weather condensation on the ...
Nanowires grown on graphene have surprising structure
26-04-2013
When a team of University of Illinois engineers set out to grow nanowires of a compound semiconductor on top of a sheet of graphene, they did not expect to discover a new paradigm of epitaxy. The self-assembled wires have a core of one composition and an outer layer of another, a desired ...
X-ray analysis could boost legumes, thus reducing fertilizer pollution
26-04-2013
The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with ...
Secret of the crystal's corners
New nanowire structure has potential to increase semiconductor applications
25-04-2013
New research led by University of Cincinnati physics professors Howard Jackson and Leigh Smith could contribute to better ways of harnessing solar energy, more effective air quality sensors or even stronger security measures against biological weapons such as anthrax. And it all starts with ...
New material approach should increase solar cell efficiency
25-04-2013
“When designing next generation solar energy conversion systems, we must first develop ways to more efficiently utilize the solar spectrum,” explained Lane Martin, whose research group has done just that. “This is a fundamentally new way of approaching these matters,” said Martin, who is an ...
New solar-cell coating could boost efficiency
22-04-2013
Throughout decades of research on solar cells, one formula has been considered an absolute limit to the efficiency of such devices in converting sunlight into electricity: Called the Shockley-Queisser efficiency limit, it posits that the ultimate conversion efficiency can never exceed 34 ...
Super-nanotubes: 'Remarkable' spray-on coating combines carbon nanotubes with ceramic
19-04-2013
Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light. Coatings that absorb as much of the energy ...
