Scientists spy unstable semiconductors

Scientists from Cardiff University have, for the first time, spotted previously unseen "instabilities" on the surface of a common compound semiconductor material.

Catch-22 in graphene based molecular devices resolved

The conductivity of Graphene has made it a target for many researchers seeking to exploit it to create molecular scale devices and now a research team jointly led by University of Warwick and EMPA have found a way past a ...

'MasSpec Pen' for accurate cancer detection during surgery

A major challenge for cancer surgeons is to determine exactly where a tumor starts and where it ends. Removing too much tissue can impair normal functions, but not taking enough can mean the disease could recur. The "MasSpec ...

Making a transparent flexible material of silk and nanotubes

The silk fibers produced by Bombyx mori, the domestic silkworm, has been prized for millennia as a strong yet lightweight and luxurious material. Although synthetic polymers like nylon and polyester are less costly, they ...

Ionic decision-maker capable of self-learning

A NIMS research group has invented an ionic device, termed an ionic decision-maker, capable of quickly making its own decisions based on previous experience using changes in ionic/molecular concentrations. The group then ...

The future of electronics is chemical

We can't cram any more processing power into silicon-based computer chips. But a paper published in Nature overnight reveals how we can make electronic devices 10 times smaller, and use molecules to build electronic circuits ...

Graphene offers new functionalities in molecular electronics

An international team of researchers led by the National Physical Laboratory (NPL) and the University of Bern has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene. ...

Researchers build a single-molecule diode

Researchers of the University of Barcelona have led a project to create a diode out of a 1 nm-sized single molecule with high rectification ratios. Diodes, commonly used in in everyday electronic devices, allow current to ...
