Silicon microcantilevers modified with a three-dimensional layer of vertical titanium dioxide nanotubes can be used in micromechanical sensors with optical signal detection to detect low levels of explosives.
Led by Professor Wang Enge at Peking University (PKU) and Professor Wang Feng at the University of California, Berkeley, a joint research team recently reported their major progress on an atlas of carbon nanotube optical transitions.
Wenn Elektronen die Energie zum ueberwinden einer Energiebarriere nicht haben, "tunneln" sie einfach durch diese Barriere hindurch. Forscher koennen den Zeitpunkt des Austritts aus der Barriere zum ersten Mal exakt bestimmen und schlussfolgern daraus: Die Zeit, die das Elektron fuer das Tunneln braucht, ist gleich Null.
Kansas State University researchers have come closer to solving an old challenge of producing graphene quantum dots of controlled shape and size at large densities, which could revolutionize electronics and optoelectronics.
Joshua Zide, assistant professor of materials science and engineering at the University of Delaware, has spent nearly a decade engineering nanomaterials using a technique called molecular beam epitaxy (MBE).
The Bay Area Photovoltaic Consortium (BAPVC) - an industry-supported program led by Stanford University and the University of California-Berkeley - has announced its first research grants aimed at making utility-scale solar power cost-competitive by the end of the decade.
To treat cancer, scientists and clinicians have to kill cancer cells while minimally harming the healthy tissues surrounding them. However, because cancer cells are derived from healthy cells, targeting only the cancer cells is exceedingly difficult.
Researchers at AIST have developed a very high-performance multilayered photoelectrode for hydrogen production by water electrolysis using an oxide semiconductor photoelectrode. In the reaction to convert solar energy into hydrogen energy, a solar energy conversion efficiency of 1.35 % has been achieved in a carbonate electrolyte by stacking two photoelectrodes.
The growing concerns on environmental damage and health impact from volatile organic compound (VOC) have initiated Thai researchers to look at ways to treating air pollutant such as benzene, toluene, ethylbenzene and xylene (BTEX) under visible light.
This signature initiative, "Nanotechnology Knowledge Infrastructure: Enabling National Leadership in Sustainable Design", will provide a community-based, solutions-oriented knowledge infrastructure to accelerate nanotechnology discovery and innovation.
