Single-atom transistor is 'perfect'

In a remarkable feat of micro-engineering, UNSW physicists have created a working transistor consisting of a single atom placed precisely in a silicon crystal.

New tool for analyzing solar-cell materials

To make a silicon solar cell, you start with a slice of highly purified silicon crystal, and then process it through several stages involving gradual heating and cooling. But figuring out the tradeoffs involved in selecting ...

All set and ready to glow

A new technique that paves the way for manufacturing affordable LED light bulbs is to be exploited in the UK, in a deal that researchers say could have a dramatic impact on carbon emissions.

New biosensor is based on a nanowire crystal array

(PhysOrg.com) -- A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which ...

Team develops method for creating 3D photonic crystals

Dutch researchers at the University of Twente's MESA+ research institute, together with ASML, TNO (the Netherlands Organisation for Applied Scientific Research) and TU/e (Eindhoven University of Technology) have developed ...

Two pairs of specs in one: Touch of finger changes prescription

If you're over 45 and wear glasses, you've probably got more than one pair. Or you're using bifocals or progressive lenses. As most people get older, their eyes have more trouble focusing on objects that are close, which ...
