New analyses of more than 4,000 scientific studies have concluded that a family of "miracle materials" called MOFs have a bright future in products and technologies - ranging from the fuel tanks in hydrogen-powered cars to muting the effects of the greenhouse gas carbon dioxide - that are critical for solving some of the greatest global challenges of the 21st century.
Never get stranded with a dead cell phone again. A promising new nanotechnology called Power Felt, a thermoelectric device that converts body heat into an electrical current, soon could create enough juice to make another call simply by touching it.
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.
