Funktionalisiertes Graphen leistet wenig Widerstand

Graphen ist an sich ein hervorragender elektrischer Leiter. Doch muss nutzbares Graphen ueber Kontakte elektrisch an die Umgebung angebunden sein - das kann sich nachteilig auf die Leitfaehigkeit auswirken. Ein Team von der Uni Duisburg-Essen hat nun erstmals nanometergenau den Widerstand an den Kontaktstellen gemessen.

Carbon nanotube device converts light energy to power implants

A device based on carbon nanotubes wrapped with polymer sheets can effectively convert laser light into thermal energy and subsequently to electricity. The converter is flexible and extremely compact, and can be manipulated by using a laser that functions in the wavelength range that can be transmitted through living tissue.

Researchers demonstrate earthquake friction effect at the nanoscale

Earthquakes are some of the most daunting natural disasters that scientists try to analyze. Though the earth's major fault lines are well known, there is little scientists can do to predict when an earthquake will occur or how strong it will be. And, though earthquakes involve millions of tons of rock, a team of University of Pennsylvania and Brown University researchers has helped discover an aspect of friction on the nanoscale that may lead to a better understanding of the disasters.
