The smaller the components in electronic circuits, the more interference-prone they are. If the components are too densely packed, they can interfere with one another. A near-field scanner can accurately detect weak fields and help to protect bank cards against fraud.
The European Parliament's environment committee this week adopted a report by Swedish Green MEP Carl Schlyter which calls for tighter controls on nanotechnology, including the application of the 'no data, no market' principle contained in the REACH Directive.
By controlling the collective spin state of highly mobile electrons in semiconductors, researchers in the Materials Sciences Division (MSD) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have taken a major step forward in the technology of spintronics.
Two Arizona State University faculty members - Erik Fisher, Ph.D., assistant research professor, Center for Nanotechnology in Society, and David H. Guston, Ph.D., director of CNS-ASU - have been awarded a three-year, $540,000 grant from the National Science Foundation.
By developing a process in which a chemical 'sleeve' tightly wraps itself around the nanotube, scientists managed to not only create a smooth new surface on the nanotube but also to 'clean' its underlying exterior of defects in a way that has never been accomplished before.
In a finding that may help speed the production of ultra-clean fuel cell vehicles powered by hydrogen, scientists in Michigan are reporting development of a sponge-like nanomaterial with a record-high surface area for holding gases.
