Smart multi-layered magnetic material acts as an electric switch

02-Mar-2017

The nanometric-size islands of magnetic metal sporadically spread between vacuum gaps display unique conductive properties under a magnetic field. In a recent study published in EPJ Plus, Anatoliy Chornous from Sumy State University in Ukraine and colleagues found that the vacuum gaps impede the ...

Scientists build bacteria-powered battery on single sheet of paper

23-Dec-2016

Instead of ordering batteries by the pack, we might get them by the ream in the future. Researchers at Binghamton University, State University of New York have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics. The manufacturing technique reduces ...

Researcher finds gold - and other metals

Gold sensor is latest in a series of metal-detecting biosensors

22-Feb-2016

Instead of a pan and a pick ax, prospectors of the future might seek gold with a hand-held biosensor that uses a component of DNA to detect traces of the element in water. The gold sensor is the latest in a series of metal-detecting biosensors under development by Rebecca Lai, an associate ...

Towards graphene biosensors

30-Jun-2015

For the first time, a team of scientists has succeeded in precisely measuring and controlling the thickness of an organic compound that has been bound to a graphene layer. This might enable graphene to be used as a sensitive detector for biological molecules in the future. Pure carbon occurs in ...
