Towards graphene biosensors

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 bi...

Why do hospital germs bind more strongly to certain surfaces than to others?

A team of physicists has shown why hospital germs adhere strongly to surfaces from which water simply rolls off, but bind so poorly to surfaces that are easily wetted by water. These results from studies in both experimental and theoretical ...

Future batteries: Lithium-sulfur with a graphene wrapper

What do you get when you wrap a thin sheet of the "wonder material" graphene around a novel multifunctional sulfur electrode that combines an energy storage unit and electron/ion transfer networks? An extremely promising electrode structure...
<b>Polariton interactions: Light matters</b>

Polariton interactions: Light matters

Why do two-dimensional exciton-polaritons interact? The answer is found to lie in the 'light-like' characteristics of these quasiparticles. This is important for future applications using polaritons in atomically-thin semiconductors, such as...
