Article in the journal 'Applied Physics Letters' shows how to boost performance for commonly used devices The mineral molybdenum disulfide (MoS2), which, when solid, behaves in many ways like grease, has semiconducting properties that make it a promising alternative to silicon or graphene in electronic devices. It also strongly absorbs visible light, and so it has been widely employed in light-sensing photodetectors, which are used in a wide range of technologies, such as environmental...

First-ever Bridge Between Optomechanics And Microfluidics Built By Researchers
2013-06-07 11:52:38

University of Illinois at Urbana-Champaign Ever been to a whispering gallery–a quiet, circular space underneath an old cathedral dome that captures and amplifies sounds as quiet as a whisper? Researchers at the University of Illinois at Urbana-Champaign are applying similar principles in the development optomechanical sensors that will help unlock vibrational secrets of chemical and biological samples at the nanoscale. "Optomechanics is an area of research in which extremely...

Tiny Bubbles In Your Metallic Glass May Be Sign Of Trouble
2013-06-06 14:36:18

Johns Hopkins University Bubbles in a champagne glass may add a festive fizz to the drink, but microscopic bubbles that form in a material called metallic glass can signal serious trouble. In this normally high-strength material, bubbles may indicate that a brittle breakdown is in progress. That´s why Johns Hopkins researchers used computer simulations to study how these bubbles form and expand when a piece of metallic glass is pulled outward by negative pressure, such as the...

Invisibility Cloak For Thermal Flow Constructed By Researchers
2013-05-08 15:09:27

Karlsruhe Institute of Technology By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. The results are presented in the Physical Review Letters journal. “For the thermal invisibility cloak, both materials...

Navy Develops High Impact, High Integrity Polymer

U.S. Naval Research Laboratory U.S. Naval Research Laboratory Chemistry Division scientists have developed a second generation, cost-effective polyetheretherketone (PEEK)-like phthalonitrile-resin demonstrating superior high temperature and flammability properties for use in numerous marine, aerospace, and domestic applications. The resin can be used to make composite components by established industrial methods such as resin transfer molding (RTM), resin infusion molding (RIM),...

A new process for growing forests of manganese dioxide nanorods may lead to the next generation of high-performance capacitors. As an energy-storage material for batteries and capacitors, manganese dioxide has a lot going for it: it´s cheap, environmentally friendly and abundant. However, chemical capacitors made with manganese dioxide have lacked the power of the typical carbon-based physical capacitor. Michigan Technological University scientist Dennis Desheng Meng theorized that...

Wyss Institute for Biologically Inspired Engineering at Harvard [ Watch the Video Adaptive Material Demonstration ] Tunable material system designed by Harvard team is easily adaptable for diverse applications in fuel transport, textiles, optical systems, and more Imagine a tent that blocks light on a dry and sunny day, and becomes transparent and water-repellent on a dim, rainy day. Or highly precise, self-adjusting contact lenses that also clean themselves. Or pipelines that can...

Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell. Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted a great deal of attention among materials scientists in the last few years. A research team at the Vienna University of Technology, together with colleagues from the USA...

A new way of making crystalline silicon, developed by U-M researchers, could make this crucial ingredient of computers and solar cells much cheaper and greener. Silicon dioxide, or sand, makes up about 40 percent of the earth's crust, but the industrial method for converting sand into crystalline silicon is expensive and has a major environmental impact due to the extreme processing conditions. "The crystalline silicon in modern electronics is currently made through a series of...
