Graphene could form basis for frictionless coatings

The discovery that graphene produces almost no friction when dragged across a gold surface suggests that it could be used as a frictionless coating.

Scientists have shown that carbon films can allow microchips to house their own power sources.

By studying metallic glasses under extreme pressures, scientists have uncovered rules that could help in the development of new varieties.

A material made of buckyballs and potassium ions becomes superconducting at -170°C when irradiated with pulses of infrared light.

Micromanipulator based on graphene and polymers mimics the extraordinary ability of gecko's feet to grip any surface and self-clean.

Scientists have uncovered evidence of electronic nematicity as a universal feature in cuprate high-temperature superconductors.

Tetrahedral cages made from DNA can be used to arrange nanoparticles in a way that mimics the crystalline structure of diamond.

For the first time, scientists have observed 'polar vortices', which could be the electrical cousins of magnetic skyrmions, in a ferroelectric material.

Efficient vertical charge transport in semiconducting polymers can be achieved by controlling the orientation of the polymer chains.

For the first time, scientists have produced three-dimensional covalent organic frameworks by weaving them from helical organic threads.

Scientists have worked out the precise arrangement of nitrogen and carbon atoms that allow nitrogen-doped carbon to act as a fuel cell catalyst.

The electrical properties of a new thin-film material can be switched between metallic and semiconducting simply by applying a small voltage.

Lithium-ion battery cathodes made from novel metal particles don't develop a crusty coating that can degrade the battery's performance.
