Flexible thin film solar cells that can be produced by roll-to-roll manufacturing are a highly promising route to cheap solar electricity. Now scientists from Empa, the Swiss Federal Laboratories for Materials Science and Technology, have made significant progress in paving the way for the industrialization of flexible, light-weight and low-cost cadmium telluride (CdTe) solar cells on metal foils. They succeeded in increasing their efficiency from below eight to 11.5 percent by doping the cells with copper.
The Minnesota Partnership for Biotechnology and Medical Genomics announced four research projects selected for funding from the 2013 Discovery Transformation Grant Program. Together, the selected researchers were awarded a total of $2 million to support their work in diabetes research.
The new electron beam writer housed in the Nano3 cleanroom facility at the Qualcomm Institute is important for electrical engineering professor Shadi Dayeh's two major areas of research. He is developing next-generation, nanoscale transistors for integrated electronics; and he is developing neural probes that have the capacity to extract electrical signals from individual brain cells and transmit the information to a prosthetic device or computer.
Researchers at the University of Rochester have measured for the first time light emitted by photoluminescence from a nanodiamond levitating in free space. They describe how they used a laser to trap nanodiamonds in space, and - using another laser - caused the diamonds to emit light at given frequencies.
Computer simulations have revealed how the electrical conductivity of many materials increases with a strong electrical field in a universal way. This development could have significant implications for practical systems in electrochemistry, biochemistry, electrical engineering and beyond.
Georgia Tech researchers want to put your signature up in lights. Using thousands of nanowires, the researchers have developed a sensor device that converts mechanical pressure - from a signature or a fingerprint - directly into light signals that can be captured and processed optically.
Nano-archimedes is a Technology Computer Aided Design tool (TCAD) for the simulation of electron transport in nanometer scale semiconductor devices (nanodevices). It is based on the Wigner equation, a convenient reformulation of the Schrödinger equation in terms of a phase-space, which allows the application of stochastic particles methods and the extension towards mixed state kinetic descriptions such as the Wigner-Boltzmann equation.
Researchers have figured out how to synthesize nanomaterials with stainless steel-like interfaces. Their discovery may change how the form and structure of nanomaterials are manipulated, particularly those used for gas storage, heterogeneous catalysis and lithium-ion batteries.
A team of chemists in SU's College of Arts and Scientists has used a temperature-sensitive polymer to regulate DNA interactions in both a DNA-mediated assembly system and a DNA-encoded drug-delivery system.
With its ever-escalating pursuit of high efficiency and low cost, the electronics industry prizes understanding specific behaviors of polymers. Now there's help in appreciating the polymer mystique related to the emerging field of molecular conduction in which films of charge-transporting large molecules and polymers are used within electronic devices.
