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

Lithography
Unmasked
Making a single silicon chip can require as many as 30 masks costing more than a
million dollars. Researchers pursue a cheaper way of designing and fabricating computer
chips.

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.
