Toward better electronics: Researchers develop new way to oxidize promising graphene
Feb 19 2012 09:33 PM
Many experts think graphene could change the face of electronics -- especially if the scientific community can overcome a major challenge intrinsic to the material. Oxidation could be the answer.
Physicists create working transistor consisting of a single atom
Feb 19 2012 09:32 PM
In a remarkable feat of micro-engineering, physicists have created a working transistor consisting of a single atom placed precisely in a silicon crystal. The tiny electronic device uses as its active compon...
New 'soft' motor made from artificial muscles
Feb 15 2012 10:53 PM
The electrostatic motor, used more than 200 years ago by Benjamin Franklin to rotisserie a turkey, is making a comeback in a promising new design for motors that is light, soft, and operates without external...
In new mass-production technique, robotic insects spring to life
Feb 15 2012 10:53 PM
A new technique inspired by elegant pop-up books and origami will soon allow clones of robotic insects to be mass-produced by the sheet. Devised by engineers, the ingenious layering and folding process enabl...
Nanotechnology may lead to more energy-efficient electronics
Feb 14 2012 05:07 PM
Carbon nanotubes and graphene consist of just a couple of layers of carbon atoms, but they are lighter than aluminium, stronger than steel and can bend like spring-coils. Physicists have been studying the un...

For disaster debris arriving from Japan, radiation least of the concerns
Ieri, 08:37 PM
Later this year debris from the earthquake and tsunami that devastated Japan should begin to wash up on US shores -- and one question many have asked is whether that will pose a radiation risk. The simple an...
