Graphene 'onion rings' have delicious potential

Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.

A quantum simulator for magnetic materials

Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. An important ...

Physicists find right (and left) solution for on-chip optics

(Phys.org) —A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize specific kinds ...

Scientists spin photons to send light in one direction

(Phys.org) —Researchers at King's College London have achieved previously unseen levels of control over the travelling direction of electromagnetic waves in waveguides. Their ground-breaking results could have far-reaching ...

Nanofibers clean sulfur from fuel

(Phys.org)—Sulfur compounds in petroleum fuels have met their nano-structured match. University of Illinois researchers developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels much more effectively ...

James' bond: A graphene / nanotube hybrid

(Phys.org)—A seamless graphene/nanotube hybrid created at Rice University may be the best electrode interface material possible for many energy storage and electronics applications.

New type of 'space weathering' observed on asteroid Vesta

The surface of the giant asteroid Vesta is weathering in a way that appears to be completely different from any other asteroid yet visited, according to new data recorded by NASA's Dawn spacecraft. This new type of space ...
