Wissenschaftler der Uni Goettingen beschaeftigen sich in einem neuen Projekt mit der Erforschung von Spinwellencomputern. Das Rechnen mit Spinwellen koennte in Zukunft eine schnellere parallele Datenverarbeitung in Mikroprozessoren ermoeglichen.
New information from the National Institute of Standards and Technology (NIST) about how layered switching devices for novel computer memory systems work may now allow these structures to come to market sooner, helping bring about faster, lower-powered computers.
Researchers have developed a "soft template infiltration" technique for fabricating free-standing piezoelectrically active ferroelectric nanotubes and other nanostructures from PZT - a material that is attractive because of its large piezoelectric response.
Electronics and electrics on or in paper is being used for security, safety, crime prevention, brand enhancement and merchandising. Cost, weight or bulk are a problem, so conventional electronics in paper products is being replaced with printed electronics.
Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries for controlling band gaps.
Faster, smaller and more energy-efficient - that is what computers of the future should be like. A new phenomenon stands to make a major contribution in this direction: It needs 100,000 times less current than existing technologies, and the number of atoms needed for a data bit could diminish significantly.
As an initial step towards the development of the WHO/NANOH Guidelines, WHO prepared a draft background document proposing content and focus of the Guidelines. This background document will be used by the Guideline Development Group to identify key questions to be addressed by the Guidelines.
Wissenschaftler haben mit Experimenten erstmals das dynamische Verhalten korrelierter einzelner Atome in Festkoerpern simuliert. Es gelang ihnen, Atome in sogenannten optischen Gittern aufzureihen und deren dynamisches Verhalten zu beobachten, das durch das komplexe Zusammenspiel mit anderen Atomen bestimmt ist.
There's nothing ordinary about the materials being designed in the Stupp Laboratory at Northwestern University. Many of the futuristic fibers, films, gels, coatings and putty-like substances have led to important advances in areas of research such as regenerative medicine and energy technologies.
A new document from DECHEMA and VCI offers a summary of papers and work which have already been completed together with the results obtained, as well as a summary of the on-going activities and expected results. Here, the main focus of our considerations is on Germany, with a wider outlook on papers and results at European level.
