Tuning graphene film so it sheds water

Researchers have figured out how to create a freestanding film of graphene oxide and alter its surface roughness so that it either causes water to bead up and run off or causes it to spread out in a thin layer.

Exotic phases on an atom chip

The realization of topological insulators with cold atoms is extremely attractive, as it would offer an ideal quantum spin Hall effect within a laboratory. In an article recently published, an international team lay out such an experiment.

UV-transparent coating for image sensors

Image sensors as used in cell phones are partially color-blind. This is because of their coating, which prevents UV light from passing through. CMOS chips have as a result not been suitable for spectroscopy up to now. A new production process makes the coating transparent - and the sensors suitable for special applications.
