Nanoscale simulations and theoretical research performed at the Department of Energy's Oak Ridge National Laboratory are bringing scientists closer to realizing graphene's potential in electronic applications.
A collaboration between CNM's Electronic & Magnetic Materials & Devices Group and Argonne's Energy Systems Division has led to an entirely new way to fabricate both two- and three-dimensional functional nanomaterials.
Harnessing darkness for practical use, researchers at the National Institute of Standards and Technology have developed a laser power detector coated with the world's darkest material -- a forest of carbon nanotubes that reflects almost no light across the visible and part of the infrared spectrum.
A team of researchers from the U.S. and France report the development of a micro-supercapacitor with remarkable properties. The paper will be published in the premier scientific journal Nature Nanotechnology online on August 15.
Scientists at Tohoku University in Japan have recorded data at a density of 4 trillion bits per square inch, which is a world record for the experimental "ferroelectric" data storage method. As described the journal Applied Physics Letters, which is published by the American Institute of Physics, this density is about eight times the density of today's most advanced magnetic hard-disk drives.
As the fastest growing energy technology in the world, solar energy continues to account for more and more of the world`s energy supply. Currently, most commercial photovoltaic power comes from bulk semiconductor materials. But in the past few years, scientists have been investigating how semiconductor nanostructures can increase the efficiency of solar cells and the newer field of solar fuels.
A little wax and soap can help build electrodes for cheaper lithium ion batteries, according to a study in August 11 issue of Nano Letters. The one-step method will allow battery developers to explore lower-priced alternatives to the lithium ion-metal oxide batteries currently on the market.
Out of sight is not out of mind for a group of Hong Kong researchers who have demonstrated that burying a layer of silver nanoparticles improves the performance of their organic electronic devices without requiring complex processing. Their findings in a report published in the journal Applied Physics Letters, which is published by the American Institute of Physics (AIP).
