Graphene spintronics: Studies show promise

News: Nanotechnology    January 31, 2011
If you’ve had any contact with the concept of ‘digital devices’ (as in theory of, not the use of) you’ve heard it explained like ‘switches’ (i.e. gates) that are either ON or OFF, zeroes or ones – the binary code – that sort of thing. Information is stored or processed based on a sequence of [...]

Graphene finds mass appeal

Impact: Nanotechnology    October 25, 2010
Thanks to the 2010 Nobel Prize for physics, graphene is a hot topic. That doesn’t mean it’s a household word. Graphene is not like pencil lead, which most people know is graphite. (That may hold for another generation or two, pencils are disappearing into tiny niches.) Yet graphene is graphite. Same stuff, pure carbon, just [...]

Ultimate sensitivity: Nanosenors

News: Sensor Technology    March 23, 2010
Everything electronic gets smaller, including sensors. Sensors are the devices that gauge your car’s tire pressure. They feel your fingers pinching an iPhone screen. They’re everywhere in modern technology, and soon they will be ultrasensitive and all but invisible – as nanosensors. There are many companies and academic laboratories working on the incorporation of nanotechnology [...]

For real: A new way to produce electricity

News: Energy Storage    March 8, 2010
It’s not every day that a new way to produce electricity is discovered…although it does seem there is a multitude of approaches. This one involves carbon nanotubes, those jacks-of-all-trades in the nanotech business, nanometer sized tubes of pure carbon. (In this case, think of them as ‘wires’ one-hundred thousandth of the thickness of human hair.) [...]
