U of Toronto Discovery of New Catalyst Promises Cheaper, Greener Drugs
Mar 29, 2012 09:47 AM E
A chemistry team at the University of Toronto has discovered environmentally-friendly iron-based nanoparticle catalysts that work as well as the expensive, toxic, metal-based catalysts that are currently in wide use by the drug, fragrance and food industry.

Getting to the Moon on Drops of Fuel
Mar 29, 2012 09:34 AM E
The first prototype of a new, ultra-compact motor that will allow small satellites to journey beyond Earth's orbit is just making its way out of the EPFL laboratories where it was built. The goal of the micro motor: to drastically reduce the cost of space exploration.

UCSB Physicists Mix 2 Lasers to Create Light at Many Frequencies
Mar 28, 2012 14:00 PM E
A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors. By aiming high- and low-frequency laser beams at a semiconductor, the researchers caused electrons to be ripped from their cores, accelerated, and then smashed back into the cores they left behind. This recollision produced multiple frequencies of light simultaneously.
Video Reveals Wave Character of Particles
Nature: Video Reveals Wave Character of Particles
Mar 28, 2012 11:17 AM E
Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of everyday's world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, an international team of researchers has recorded the interference process of individual molecules.

Researchers Discover a New Path for Light Through Metal
Mar 27, 2012 12:58 PM E
Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light that can direct and manipulate optical signals on the nanoscale. Titanium nitride's addition to the short list of surface-plasmon-support...

A New Dimension for Solar Energy
Mar 27, 2012 06:35 AM E
Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.

More Energy Efficient Transistors through Quantum Tunneling
Mar 26, 2012 15:35 PM E
Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level.

The Lithium Battery as a Source of Hope
Mar 23, 2012 13:53 PM E
The future belongs to electric vehicles - the experts are convinced of this. But there are a few challenges to overcome before quietly whirring electric cars can completely replace the combustion engine. One such challenge is the power supply: batteries have to be safe, reliable and reasonably priced. Promising developments in this area include lithium cells, which offer the highest energy density.
