Researchers from the Institute of High Performance Computing of A*STAR, Singapore, in collaboration with co-workers from CSIRO Materials Science and Engineering, Australia, have now revealed how metallic nanostructures can enhance light absorption - even in very thin silicon films - and thus increase the performance of thin-film solar cells.
With the passage of a molecule through the labyrinth of a chemical system being so critical to catalysis and other important chemical processes, computer simulations are frequently used to model potential molecule/labyrinth interactions. In the past, such simulations have been expensive and time-consuming to carry out, but now researchers have developed a new algorithm that should make future simulations easier and faster to compute, and yield much more accurate results.
Prof. Thomas Elsaesser vom Max-Born-Institut fuer Nichtlineare Optik und Kurzzeitspektroskopie in Berlin erhaelt vom Europaeischen Forschungsrat (ERC) einen 'Advanced Grant' in Hoehe von 2,49 Millionen Euro. Ziel des ausgezeichneten Forschungsprojekts ist die Aufklaerung extrem schneller Prozesse, die die Eigenschaften von Wasserstoffbruecken in molekularen Systemen bestimmen.
Microelectronic chips used to take pressure readings are very delicate. A new technology has been developed that makes pressure sensors more robust, enabling them to continue operating normally at temperatures up to 250 degrees Celsius.
A new intelligent system has been developed to help identify terrorists carrying explosives. Sensitive electronic noses capture the smell of the explosives; the system processes the acquired data, correlates it with individuals' movements - and ultimately tracks down the suspects.
A team of researchers in California and Massachusetts has developed a 'cocktail' of different nanometer-sized particles that work in concert within the bloodstream to locate, adhere to and kill cancerous tumors.
One of the most important catalysts in the modern chemical industry is a troublemaker. The building blocks of zeolite ZSM-5 crystals, which are a sort of Swiss cheese with molecular size holes, are not joined together perfectly. The materials that have to pass through the crystals therefore often get stuck and don't react well. A researcher has discovered the deviations in the miniscule but indispensable particles.
Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo.
n the current issue of Science, Stuart Lindsay, director of Arizona State University's Center for Single Molecule Biophysics at the Biodesign Institute, along with his colleagues, demonstrates the potential of a method in which a single-stranded ribbon of DNA is threaded through a carbon nanotube, producing voltage spikes that provide information about the passage of DNA bases as they pass through the tube - a process known as translocation.
Federal research dollars will help South Dakota State University scientists build a first-of-its-kind microscope that could ultimately help scientists at SDSU and elsewhere develop better solar cells for converting sunlight to electricity.
