Touchscreens Made of Carbon – Nanotechnology

Press Release 27.01.2011

Touchscreens are in – although the technology still has its price. The little screens contain rare and expensive elements. This is the reason why researchers at Fraunhofer are coming up with an alternative display made of low-priced renewable raw materials available all over the world. The researchers are presenting touchscreens that contain carbon nanotubes at the nano tech 2011 fair in Tokyo (Hall 5, Stand E-18-11) from February 16-18.

Just touching it slightly with the tips of your fingers is enough. You can effortlessly write, navigate, open menu windows or rotate images on touchscreens. Within fractions of a second your touch is translated into control commands that a computer understands...

Buckminsterfullerene – buckyball – New Google logo 25 years of Buckminsterfullerene

Buckminsterfullerene - buckyball

A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube. Spherical fullerenes are also called buckyballs, and cylindrical ones are called carbon nanotubes or buckytubes. Fullerenes are similar in structure to graphite, which is composed of stacked graphene sheets of linked hexagonal rings; but they may also contain pentagonal (or sometimes heptagonal) rings.

Buckminsterfullerene - buckyball

The first fullerene to be discovered, and the family’s namesake, was buckminsterfullerene (C60), prepared in 1985 by Richard Smalley, Robert Curl, James Heath, Sean O’Brien, and Harold Kroto at Rice University. The name was an homage to Richard Buckminster Fuller, whose geodesic domes it resembles.

Fullerenes have since been found to occur (if rarely) in nature.[1]
