Researchers from the Eindhoven University of Technology and the University of Ulm have made the first high-resolution 3D images of the inside of a polymer solar cell. This gives them important new insights in the nanoscale structure of polymer solar cells and its effect on the performance. The findings were published online in Nature Materials on Sunday 13 September.
Berkeley, CA - In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S.
Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own.
COLUMBIA, Mo. -- The Lost Orphan Mine below the Grand Canyon hasn't produced uranium since the 1960s, but radioactive residue still contaminates the area.
MADISON -- Music is one of the surest ways to influence human emotions; most people unconsciously recognize and respond to music that is happy, sad, fearful or mellow. But psychologists who have tried to trace the evolutionary roots of these responses usually hit a dead end. Nonhuman primates scarcely respond to human music, and instead prefer silence.
A new method for "recycling" hydrogen-containing fuel materials could open the door to economically viable hydrogen-based vehicles.
Barcelona, Spain, 30 August: Several large observational data sets have convincingly shown that there is no overall safety issue with drug eluting stents (DES) vs. bare metal stents (BMS). In fact, most registry studies suggest a lower risk of death or myocardial infarction with drug eluting stents.
Barcelona, Spain, 31 August: Drug-eluting stents (DES), which slowly release medication to inhibit the build-up of scar tissue, have proved very successful in preventing restenosis (renarrowing) of stented coronary arteries. However, several studies have shown persistent risk of blood clot formation inside DES over a longer time period after implantation than observed with bare metal stents.
PROVIDENCE, R.I. [Brown University] -- Carbon nanotubes hold many exciting possibilities, some of them in the realm of the human nervous system. Recent research has shown that carbon nanotubes may help regrow nerve tissue or ferry drugs used to repair damaged neurons associated with disorders such as epilepsy, Parkinson's disease and perhaps even paralysis.
The century-old challenge of transporting acetylene may have been solved in principle by a team of scientists working at the National Institute of Standards and Technology (NIST). A NIST research team has figured out* why a recently discovered material can safely store at low pressure up to 100 times as much of the volatile chemical as can be done with conventional methods.
The sandwich recipe recently concocted by scientists working at the National Institute of Standards and Technology (NIST) may prove tasty for computer chip designers, who have long had an appetite for molecule-sized electronic components -- but no clear way to satisfy it until now.
Using thin films of silk as templates, researchers have incorporated inorganic nanoparticles that join with the silk to form strong and flexible composite structures that have unusual optical and mechanical properties.
WASHINGTON, Aug. 17, 2009 -- Scientists have copied the natural glue secreted by a tiny sea creature called the sandcastle worm in an effort to develop a long-sought medical adhesive needed to repair bones shattered in battlefield injuries, car crashes and other accidents. They reported on the adhesive here today at the 238th National Meeting of the American Chemical Society (ACS).
PITTSBURGH -- Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from mines to spacecrafts.
WASHINGTON, Aug. 16, 2009 -- The American Chemical Society's (ACS) 238th National Meeting here will be the site of a rare "thought experiment" intended to focus the creative genius of hundreds of scientists on solutions to one of the 21st Century's most daunting problems: Finding sustainable new sources of energy. The exercise will use a computer game format in the Walter E.
