Physicists at Harvard University have, for the first time, tracked individual atoms in a gas cooled to extreme temperatures as the particles reorganized into a crystal, a process driven by quantum mechanics.
Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on semiconductor nanocrystals, or quantum dots, led by chemist Xiaoyang Zhu at The University of Texas at Austin.
Als Eroeffnungsveranstaltung des Landesexzellenzclusters Nanospintronics findet vom 16. bis 18. Juni 2010 im Hotel Vierjahreszeiten in Hamburg das Europaeische Symposium Nanospintronics mit 150 internationalen und nationalen Wissenschaftlern statt, die ueber neueste Erkenntnisse und Innovationen auf dem Gebiet der Nano-Spintronik diskutieren werden.
The Citizen Alliance on the ChallEnges of Nanotechnologies (CACEN) (in French 'Alliance Citoyenne sur les Enjeux des Nanotechnologies': ACEN) has just opened a new website nano.acen-cacen.org where citizens can find and share information, questions, and analyses about societal issues raised by nanotechnologies.
The Technology Strategy Board and EPSRC led cross-Research Council programme on nanotechnology are working closely together to stimulate the development and commercialisation of exciting new ideas in next generation solar energy harvesting.
Im Regionalforum Materialographie Saar haben sich jetzt Firmen, die Werkstoffe pruefen und ihre Qualitaet ueberwachen, mit der universitaeren Forschung vernetzt. Auf Initiative von Frank Muecklich, Professor fuer Funktionswerkstoffe der Universitaet des Saarlandes und Direktor des Steinbeis-Zentrums fuer Materialforschung (MECS), werden sich Metallographen, Werkstoffpruefer, Techniker und Ingenieure kuenftig regelmaessig ueber neue Verfahren austauschen.
Physicists at the University of Sydney have brought silicon chips closer to performing all-optical computing and information processing that could overcome the speed limitations intrinsic to electronics, with the first report published of an on-chip all-optical temporal integrator.
Scientists can now peer into the inner workings of catalyst nanoparticles 3,000 times smaller than a human hair within nanoseconds. The findings point the way toward future work that could greatly improve catalyst efficiency in a variety of processes that are crucial to the world's energy security, such as petroleum catalysis and catalyst-based nanomaterial growth for next-generation rechargeable batteries
With hands-on experiences in childhood and adolescence having sparked so many science careers, scientists in Canada are describing a quick, simple, safe, and inexpensive way for kids to participate in making microfluidic devices.
Researchers at Rensselaer Polytechnic Institute have developed a new, ultra-simple method for making layers of gold that measure only billionths of a meter thick. The process, which requires no sophisticated equipment and works on nearly any surface including silicon wafers, could have important implications for nanoelectronics and semiconductor manufacturing.
TU/e researchers want to develop solar cells with an efficiency of over 65 percent by means of nanotechnology. In Southern Europe and North Africa these new solar cells can generate a substantial portion of the European demand for electricity. The Dutch government reserves EUR 1.2 million for the research.
For the very first time, a team of researchers in Germany has introduced quantum dots in fully epitaxial nitride laser structures without the need for hybrid systems - effectively eliminating the cumbersome method of combining different materials from epitaxy and evaporation.
