Engineers at the University of California, Berkeley, have shown that it is possible to reduce the minimum voltage necessary to store charge in a capacitor, an achievement that could reduce the power draw and heat generation of today's electronics.
A new $13-million National Science Foundation center based at the University of Michigan will develop high-tech materials that manipulate light in new ways. The research could enable advances such as invisibility cloaks, nanoscale lasers, high-efficiency lighting, and quantum computers.
By demonstrating for the first time a 40Gbit/s optical modulator in silicon with a record extinction ratio of 10dB (the power difference between the 1 and 0 data levels), members of the HELIOS Project accomplished one of the key project goals needed to build and optimize the entire supply chain for fabricating complex functional silicon- photonics devices from design to the process level.
Inspired by the Nobel Prize-winning research on the mechanical exfoliation of graphene using 'scotch tape', researchers have now devised a method for the separation of semiconducting and metallic CNTs without damaging them.
New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.
The U.S. Department of Energy's Advanced Research Projects Agency - Energy (ARPA-E) Director, Arun Majumdar, announced yesterday that the Agency will hold its third annual ARPA-E Energy Innovation Summit from February 27 - 29, 2012 at the Gaylord Convention Center just outside Washington, D.C
The National Science Foundation (NSF) yestertoday announced awards for three Materials Interdisciplinary Research Teams (MIRT) and nine Centers of Excellence in Materials Research and Innovation, also known as Materials Research Science and Engineering Centers (MRSEC). The awards resulted from the 2011 Materials Research Centers and Teams competition (solicitation NSF 10-568).
Welche Wege Nanopartikel im Organismus nehmen und was das fuer Folgen hat, erforschen seit drei Jahren Wissenschaftler in Deutschland unter Leitung der Uni Duisburg-Essen. Nun liegen erste Ergebnisse vor, die sie vom 11. bis 15. September bei einer internationalen Konferenz am Campus Essen diskutieren wollen: "International Conference on Biological Responses to Nanoscale Particles".
An expedition through the fast-paced microscopic world of atoms reveals electrons that spin at enormous speeds and the gigantic forces that act on them. Monitoring the ultrafast motion of these electrons requires ultrashort flashes of light. However, in order to control them, the structure of these light flashes, or light pulses, needs to be tamed as well. This type of control over light pulses has now been achieved, for the first time.
