First controllable 2D nanopatterns imaged by Sandia researchers
Coffee beans spilled upon a table form no pattern, they’re  a mess, their distribution dictated by the laws of chance. The same was generally believed true of atoms deposited upon a substrate. Now, the first vision of a peaceable kingdom in which deposited atoms form orderly, controllable 2-D nanopatterns has been observed by researchers at the Department of Energy’s Sandia National Laboratories.
Chemical switches control light
Novel molecular alignments offer promise for designing wires, gates and light-harvesting arrays. Chemists at Washington University in St Louis, North Carolina State University and the University of California, Riverside all in the US, have found a new design for molecular electronic switches and have identified the key process that determines their efficiency

Scientists drive solar cells forward
Self-assembling photovoltaics could lead the way to harnessing the Sun's rays cheaply and efficiently. Schmidt-Mende and colleagues from the UK-based Cambridge University and Germany's Max-Planck Institute of Polymer Research have created a cheap organic photovoltaic cell that converts up to 34 ?f incident light into electricity.

New bar coding system helps decode drug delivery
Purdue University chemists have developed a way to "bar code" individual compounds, making it quick, easy and economical to identify the most biologically active ones among thousands of candidates in the drug-screening process.

Fluorescent molecules that detect metal pollutants in water, waste
A team of Brigham Young University researchers has created molecules that glow in presence of certain pollutants, paving the way for an early warming system that can alert regulators to the contamination of drinking water and waste streams.
