Graphene sensors detect HIV DNA

Leiden and Jülich researchers discovered an elegant and simple approach to improve the sensitivity of graphene biosensors. These so-called 'next generation graphene electronic biochemical sensor devices' are able to detect ...

Turning a pinch of salt into an electrical switch

A team of scientists from the University of Liverpool, University College London and the University of Zaragoza in Spain has discovered a way to induce and control a fundamental electrical switching behaviour on the nano-scale.

Taming 'wild' electrons in graphene

Graphene - a one-atom-thick layer of the stuff in pencils - is a better conductor than copper and is very promising for electronic devices, but with one catch: Electrons that move through it can't be stopped.

Nanotube fiber antennas as capable as copper

Fibers made of carbon nanotubes configured as wireless antennas can be as good as copper antennas but 20 times lighter, according to Rice University researchers. The antennas may offer practical advantages for aerospace applications ...

Low-cost battery from waste graphite

Lithium ion batteries are flammable and the price of the raw material is rising. Are there alternatives? Yes: Empa and ETH Zürich researchers have discovered promising approaches as to how we might produce batteries out ...
