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.

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.

The first known statistical theory for determining the toughness of polycrystalline graphene has revealed that it's strong but not very tough.

Scientists have produced clean interfaces between materials with different crystal structures by making a bridge between them.

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

A novel hybrid polymer combines a covalent compartment that provides the skeleton with a supramolecular compartment that can wear away.

A new theory can predict exactly how much light is transmitted through a material, given its thickness and degree of stretch.

Oxygen molecules scattered within layers of otherwise pristine graphene affect how the layers interact with each other under strain.

Scientists have developed computer models of hybrid materials that combine graphene with nanotubes made from either carbon or boron nitride.
