Flowing structures in soft crystals

August 8, 2011 6:34 am | News | Comments

A liquid does not have to be a disordered bunch of particles. A team of researchers at Vienna University of Technology and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids. Under mechanical strain, particle clusters in liquids can spontaneously form strings and alter the properties of the liquid.

Researchers strive to increase awareness of forgotten essential nutrient

August 8, 2011 6:14 am | by Andrea Hill | News | Comments

Choline, a nutrient found in foods such as egg yolks, liver and soybeans, does not appear to be high on anyone’s list of eating priorities, say University of Alberta researchers. But it’s crucial to a number of biological functions, and the liver doesn’t naturally produce enough to deliver the full benefits.

Nanoscale secret to stronger alloys

August 8, 2011 5:44 am | News | Comments

As long ago as the Wright Brothers' first airplane engine, metallurgists were using nanoparticles to make strong aluminum alloys. Researchers at Lawrence Berkeley National Laboratory have now solved the mystery of one of the most promising alloys ever for strength, hardness, lightness, and resistance to corrosion and heat, one that includes core-shell nanoparticles all nearly the same size.

Findings about nature of electrons could advance optoelectronics

August 5, 2011 8:01 am | News | Comments

Using a newly developed type of spectroscopy, researchers in Germany have for the first time shown that electrons in a semiconductor are best described as a cloud with a size of a few nanometers. The cloud size is determined by the interaction of the electron with vibrations in the crystal lattice.

Unexpected delay detected at ultrafast speed

August 5, 2011 7:56 am | News | Comments

Molecules that suddenly transform into new structures when stimulated by photons or electrons play key roles in many chemical and biological processes. But their inner workings remain mysterious because the charge-transfer dynamics happen too quickly for detection by typical instruments. A new ultrafast laser spectroscopy method deeveloped at RIKEN in Japan is able to track these changes, uncovering a remarkable phenomenon.
