The researchers, from the College's Department of Materials Science and Engineering, report that the MXene titanium carbide can be dissolved in water to create an ink or paint. The exceptional conductivity of the material enables it to transmit and direct radio waves, even when it's applied in a very thin coating. "We found that even transparent antennas with thicknesses of tens of nanometers were able to communicate efficiently," said Asia Sarycheva, a doctoral candidate in the A.J. Drexel Nanomaterials Institute and Materials Science and Engineering Department. "By increasing the thickness up to 8 microns, the performance of MXene antenna achieved...

New Energy Technologies, Inc. (OTCBB: NENE), developer of MotionPower™ technologies for generating sustainable electricity from the kinetic energy of moving vehicles and SolarWindow™ technologies capable of generating electricity on see-thru glass windows, today announced that researchers have developed a novel, patent-pending process for ‘spraying’ solar cells and their related components onto glass – a technical achievement recently presented in AZoNano’s (peer-reviewed, Journal of Nanotechnology Online; Dec. 20, 2009), “Nanotechnology Thought Leaders” series. “The ability to spray solar coatings directly onto glass follows on the heels of our recent breakthrough which replaced visibility-blocking metal with environmentally-friendly see-thru compounds, and marks...

GERMAN sex educators plan to launch a spray-on condom tailor-made for all sizes. Jan Vinzenz Krause from the Institute for Condom Consultancy, a Singen-based practice that offers advice on condom use, said today the product aimed to help people enjoy better and safer sex lives. "We're trying to develop the perfect condom for men that's suited to every size of penis," he said. "We're very serious." Mr Krause's team (spraykondom.de) is developing a type of spray can into which the man inserts his penis first. At the push of a button it is then coated in a rubber condom. "It...
