On the nanoscale, adding fluorine to graphene had been reported to vastly increase the friction experienced when sliding against the material. Through a combination of physical experiments and atomistic simulations, researchers have discovered the mechanism behind this surprising finding, which could help researchers better design and control the surface properties of new materials.

Using an 'electric prism', scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways. Since water is such a fundamental molecule in the universe, the recent study may impact a multitude of research areas ranging from biology to astrophysics.

Researchers developed a new method to selectively dope graphene molecules with nitrogen atoms. By seamlessly stringing together doped and undoped graphene pieces, they were able to form heterojunctions in the nanoribbons, thereby fulfilling a basic requirement for electronic current to flow in only one direction when voltage is applied - the first step towards a graphene transistor.

A new route to making graphene has been discovered that could make it easier to ramp up to industrial scale. Graphene, which has super strength and the ability to conduct heat and electricity better than any other known material, has potential industrial uses that include flexible electronic displays, high-speed computing, stronger wind-turbine blades, and more-efficient solar cells, among other uses now under development.
