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.

Self-cleaning gecko feet inspire micromanipulator

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

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

A new technique can create nearly two-dimensional nanosheets from compounds that do not naturally form such thin materials.

New CVD growth process can produce high quality wafers of single crystal graphene fast.

Patterning chemical arrays that attract water on a surface that repels water offers a novel way to control the spread of frost.

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

Researchers have used magnetic fields to control the semiconductor properties of topological insulator nanoribbons.

Scientists have engineered the transition point of vanadium dioxide, allowing them to control the temperature at which the transition occurs.

Scientists have developed a novel method, termed bubble-pen lithography, that uses microbubbles to inscribe nanoparticles onto a surface.
