Researchers have demonstrated a new low energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries and grain interiors in cadmium telluride (CdTe) solar cells. Their results suggest that controlling material properties near the grain boundaries could provide a path for increasing the efficiency of such solar cells.
If silicon is squeezed, this affects the freedom of movement of the electrons in this material. This can promote or restrict the flow of electrical current. Compare it to a garden hose. When you stand on it, less water comes out. But strangely enough, the flow of electrons in silicon actually increases when the material is compressed.
Cyber and nanotechnologies took full focus for 26 of the Partnership for Peace Consortium's Emerging Security Challenges Working Group during a two-day workshop hosted at the Swedish National Defense College in Stockholm November 20-22.
Thailand is willing to tell it all at the Seed and Need Seminar on January 31 during nanotech 2014 at Tokyo Big Sight, Tokyo, Japan. The title of the presentation is 'Nanotechnology Development in Thailand'.
Researchers have been working on the optimization of the third-generation sequencing technique based on nanopore. They found that long chain DNA with low salt concentration is more conducive to the nanopore sequencing process.
From Sept. 15 to Dec. 22, the 2014 Cornell Council for the Arts (CCA) Biennial, 'Intimate Cosmologies: The Aesthetics of Scale in an Age of Nanotechnology', will feature several events and principal projects by faculty and student investigators and guest artists.
Researchers used a unique optical metamaterial with a refractive index of zero to generate 'phase mismatch-free nonlinear light', meaning the generated light waves move through the material gaining strength in all directions. This phase mismatch-free quality holds promise for quantum computing and networking, and future light sources based on nonlinear optics - the phenomena that occur when interactions with light modify a material's properties.
Scientists from NIST and Sandia National Laboratories have added something new to a family of engineered, high-tech materials called metal-organic frameworks: the ability to conduct electricity. Conductive MOFs have the potential for use in a variety of applications including sensors for detecting gases and toxic substances.
Research scientists at the U.S. Naval Research Laboratory (NRL) Electronics Science and Technology Division in collaboration with researchers at University at Buffalo-The State University of New York (SUNY) demonstrate the possibility for new optical devices using graphene for communications, imaging and signal processing.
A revolutionary instrument that will expedite the discovery of new, artificial forms of matter with unprecedented electronic and magnetic properties will be funded by a $4.13 million gift from the Gordon and Betty Moore Foundation.
Researchers have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. This development will have future implications in the guided delivery of oil and effective blockage of oil spreading.
