Researchers were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighbouring QD. A single electron "surfs" thus from one quantum dot to the next like a fish on a wave. Such manipulation of a single electron will in the future also enable the combination of considerably more complex quantum bits instead of classical bits.
A study published by researchers at the RIKEN Advanced Science Institute (ASI) has shed first-ever light on a class of heterometallic molecular structures whose unique features point the way to breakthroughs in the development of lightweight fuel cell technology.
Recent theoretical work conducted at the NIST Center for Nanoscale Science and Technology explains the surprisingly small effect of macroscale phase segregation on the overall efficiency of blended organic photovoltaic materials by showing that electrons can effectively burrow through a skin layer to get to the device's cathode.
The U.S. Department of Energy's Brookhaven National Laboratory and Nanofactory Instruments, AB, a Swedish company that develops and markets scanning probe microscopy instrumentation, have received the 2011 Microscopy Today Innovation Award.
A new 'smart' window system has the unprecedented ability to inexpensively change from summer to winter modes, darkening to save air conditioning costs on scorching days and returning to crystal clarity in the winter to capture free heat from the sun, scientists are reporting.
In the framework of the Polish Presidency of the EU Council 2011, the European Commission Joint Research Centre and EASAC (the European Academies Science Advisory Council) jointly organise this event in Brussels, including the launch of the report "Impact of engineered nanomaterials on human health: considerations on benefit-risk assessment".
As part of IBM Research's newly extended global Summer intern program, eight undergraduate students from Rensselaer Polytechnic Institute (RPI), Union College, and University of Notre Dame, joined IBM Research Zurich in Switzerland for two months.
The technology yielding flexible solar cells with an 18.7% world record efficiency developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, has now been published in Nature Materials.
IDTechEx, the organiser of the World's largest global series of Printed Electronics events will hold its European show in Berlin, Germany on April 3-4. The focus, as at all IDTechEx events, is to address the needs and experiences of adopters of the technology.
New hybrid carbon material, which combines both graphene and SWNTs, Graphene Nanoribbons encapsulated into Single-Walled Carbon Nanotubes (GNR@SWNTs) have been discovered by researchers from Aalto University (Finland) and Umea University.
Researchers used a combination of four techniques to make the first detailed images of nitrogen-doped graphene film. They showed that individual nitrogen atoms had taken the places of carbon atoms in the two-dimensional sheet; that about half of the extra electron contributed by each nitrogen atom was distributed throughout the graphene lattice; and that this changed the electronic structure of the graphene sheet only within a short distance - about the width of two carbon atoms - from the dopant atoms.
With the aim of continuing to promote industrial innovation based on state-of-the-art technologies, CSEM has opened a new innovation center in Muttenz, with the support of the Canton of Basel-Landschaft. The polytronics development center is involved in the mass production of organic electronics.
As part of the research programmes, CRANN will assist Merck Millipore to further develop the nanostructures of their products' artificial membranes, that are widely used for medical and diagnostic devices, and to deliver new products with improved membrane performances.
