Es gibt noch grosse Wissenslücken im Hinblick auf das Verhalten und den Verbleib von Nanomaterialien in der Umwelt. Das Umweltbundesamt (UBA) adressierte diese Problematik und untersuchte in einem durch das Bundesumweltministerium finanzierten Vorhaben wie sich nano-Titandioxid in simulierten Kläranlagen und Böden verhält.
Researchers have developed a new method for the detailed study of the interaction between pharmaceuticals and their target proteins. The pharmaceutical industry has already taken notice of the new infrared spectroscopy technique.
Svetlana Kilina, Ph.D., assistant professor of chemistry and biochemistry at North Dakota State University, Fargo, has received a $750,000 five-year award from the U.S. Department of Energy Office of Science Early Career Research Program. Funding will be used to conduct research outlined in Dr. Kilina's proposal titled "Modeling of Photoexcited Process at Interfaces of Functionalized Quantum Dots".
Researchers from North Carolina State University have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.
Researchers at Argonne National Laboratory's Center for Nanoscale Materials have observed a stable body-centred tetragonal phase in silver nanoparticles with fivefold twinning even at ambient conditions.
Nanoparticles synthesized from noble metals such as ruthenium, rhodium, palladium, silver (Ag), osmium, iridium, platinum, and gold (Au) are attracting increased attention by researchers around the world looking for advances in such fields as biomedicine and catalysts.
By measuring the unique properties of light on the scale of a single atom, researchers from Duke University and Imperial College, London, believe that they have characterized the limits of the ability of metals to be used in devices that rely on the enhancement of light.
Researchers have learned how to mass produce tiny mechanical devices that could help cell phone users avoid the nuisance of dropped calls and slow downloads. The devices are designed to ease congestion over the airwaves to improve the performance of cell phones and other portable devices.
NIST Center for Nanoscale Science and Technology researchers Gregg Gallatin and Andrew Berglund (now at Quantifind in Palo Alto, CA) have determined the optimum path in which to scan a laser beam in order to track a fluorescing nanoparticle as the particle moves inside a fluid or gas in two or three dimensions.
In a new position paper, BEUC outlines which elements such a definition should contain in order to effectively protect consumers from unknown hazards that may be related to cosmetic products which use new nanomaterials.
The imaging of cellular events in high resolution is the dream of many life scientists. A European consortium initiated a collective effort to push the current limits of high-resolution imaging techniques for the study of biological systems.
