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.
Ultimately, the technique, based on manipulating parahydrogen, the fuel of the space shuttle, is expected to allow doctors to learn far more about a patient's condition from an MRI scan at lower cost while increasing the range of medical conditions that can be examined.
The power of magnetism may address a major problem facing bioengineers as they try to create new tissue -- getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish that growth.
