Scientists of the Fraunhofer IPMS succeeded in fabricating a large solar cell module (80 x 20 square centimeters) based on organic solar cells, which will be presented for the first time at the EU PVSEC 2010.
Just as cilia lining the lungs help keep passages clear by moving particles along the tips of the tiny hair-structures, man-made miniscule bristles known as nano-brushes can help reduce friction along surfaces at the molecular level, among other things. In their latest series of experiments, Duke University engineers have developed a novel approach to synthesize these nano-brushes, which could improve their versatility in the future.
As an early career scientist, Max Fontus wondered how successful researchers repeatedly make discoveries worth publishing. Collaborating with a Princeton engineering professor this summer, he realized that working with scientists from other fields of research results in a cross-pollination of ideas that lays the foundation for great progress in science.
Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary to use other molecules as messengers.
The Pittcon Program Committee is pleased to announce that Dr.Chad A. Mirkin, Professor of Chemistry, Northwestern University, Evanston, Illinois, will deliver the Pittcon 2011 Plenary Lecture, 'Polyvalent DNA Architectures: New Modalities For Intracellular Gene Regulation and Detection' on Sunday, March 13, 2011, at 4:30 p.m., in the Sidney Marcus Auditorium, Georgia World Congress Center, Atlanta, Georgia.
A rheological technique, used by researchers at National Nanotechnology Center (NANOTEC) in Thailand has revealed the instability of y-oryzanol-loaded solid lipid nanoparticles er 60 days storage at three different temperatures of 4, 25, and 40C.
A team of scientists at Rutgers University has found a material in which an electric field can control the overall magnetic properties of the material. If the magnetoelectric effect discovered by the Rutgers group can be extended to higher temperatures, it could be useful for manipulating small-scale magnetic bits in ultra high-density data storage.
New Jersey Institute of Technology (NJIT) researchers were awarded 15 new U.S. patents this past year, increasing the total number of issued patents for NJIT to 97. More than 150 applications are in process.
Nanoscale simulations and theoretical research performed at the Department of Energy's Oak Ridge National Laboratory are bringing scientists closer to realizing graphene's potential in electronic applications.
The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers have now discovered how to control this effect in nanoscale semiconductors called quantum dots, enabling the development of incredibly tiny new products.
In einem interdisziplinaeren Projekt ist es Wissenschaftlern des KIT gelungen, eine neue Erscheinungsform von optischen Resonatoren zu schaffen: Mikrokelche. Diese Polymerstrukturen sind durch ihre Form und ihre glatte Oberflaeche besonders effiziente Quellen fuer Laserlicht. Zudem haben sie das Potenzial kleinste Bio-Molekuele, Viren oder Gefahrstoffe nachzuweisen.
