Slow 'hot electrons' could improve solar cell efficiency

Photons with energy higher than the 'band gap' of the semiconductor absorbing them give rise to what are known as hot electrons. Scientists have now found a material in which these hot electrons retain their high energy levels for much longer.

Researchers measure single atoms in a graphene 'petri-dish'

Researchers have shown that graphene and boron nitride can be combined to create a perfect nano petri-dish. Liquid samples inside the dish can be imaged with single atom sensitivity and it is also possible to measure their elemental composition at the nanometre length scale.

Protein handshake on the nanoscale

A new study shows that it is possible to create hybrid protein nanofibers composed of two plasma proteins using a facile self-assembly approach supported by ethanol-induced protein denaturation.
