Single-atom tractor beams power chemical catalysis

By trapping light into tiny gaps only a few atoms wide, a team from the NanoPhotonics Center at the Cavendish Laboratory at the University of Cambridge has magnified optical forces a thousand-fold, strong enough to force ...

'Hot' graphene reveals migration of carbon atoms

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on ...

This light-powered catalyst mimics photosynthesis

By mimicking photosynthesis, the light-driven process that plants use to produce sugars, MIT researchers have designed a new type of photocatalyst that can absorb light and use it to drive a variety of chemical reactions.

Igniting plasmas in liquids

Physicists of Ruhr-Universit├Ąt Bochum (RUB) have taken spectacular pictures that allow the ignition process of plasma under water to be viewed and tracked in real time. Dr. Katharina Grosse has provided the first data sets ...

Molecular switch enables photomechanical jumping of polymers

Jumping movement is commonly observed in nature, including for mammals, insects and the other land creatures; this fluid motion aims for rapid mobility, a faster arrival time at a destination over large obstacles and rough ...
