UH collaboration with Universite de Montreal published in Nature Communications A new theoretical model developed by professors at the University of Houston (UH) and Université de Montréal may hold the key to methods for developing better materials for solar cells. Eric Bittner, a John and Rebecca Moores Professor of Chemistry and Physics in UH's College of Natural Sciences and Mathematics, and Carlos Silva, an associate professor at the Université de Montréal and Canada Research...

Tunable electrical behavior not previously realized in conventional devices As electronics approach the atomic scale, researchers are increasingly successful at developing atomically thin, virtually two-dimensional materials that could usher in the next generation of computing. Integrating these materials to create necessary circuits, however, has remained a challenge. Northwestern University researchers have now taken a significant step toward fabricating complex nanoscale electronics....

Alan McStravick for redOrbit.com - Your Universe Online In 2004, the pure carbon material known as graphene was isolated by two University of Manchester Nobel Laureates, Andre Geim and Professor Kostya Novoselov, quickly leading to the discovery of a whole new family of one-atom-thick materials. Now researchers from the University of Manchester and National University of Singapore have shown that by building multi-layered heterostructures of graphene in a three-dimensional stack,...

“When designing next generation solar energy conversion systems, we must first develop ways to more efficiently utilize the solar spectrum,” explained Lane Martin, whose research group has done just that. “This is a fundamentally new way of approaching these matters,” said Martin, who is an assistant professor of materials science and engineering (MatSE) at Illinois. “From these materials we can imagine carbon-neutral energy production of clean-burning fuels,...

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...

Berkeley Lab Researchers Discover Why Pure Quantum Dots and Nanorods Shine Brighter To the lengthy list of serendipitous discoveries — gravity, penicillin, the New World — add this: Scientists with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment. Better still, they´ve also discovered how to correct the problem. A...

Dr. Ariando of the National University of Singapore discovered a collective electronic state not seen before in the bulk of either 2 individual insulating oxides, thus demonstrating that electrons at their interface can now exhibit ferromagnetism In many ionic materials, including the oxides, surfaces created along specific directions can become electrically charged. By the same token, such electronic charging, or 'polarization', can also occur at the interface of two connecting materials....

While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus"”a new way to create nanowires that produce light similar to that from light-emitting diodes (LEDs). These "nano-LEDs" may one day have their light-emission abilities put to work serving miniature devices such as nanogenerators or lab-on-a-chip systems.Nanowires typically are "grown" by the controlled deposition of...

A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. The research team, using only chemical reactants, transformed semiconducting nanowires into a variety of useful, nanoscale materials including nanoscale metal strips with periodic stripes and semiconducting patterns,...
