Graphene isn't the only Lego in the materials-science toy box

You may have heard of graphene, a sheet of pure carbon, one atom thick, that's all the rage in materials-science circles, and getting plenty of media hype as well. Reports have trumpeted graphene as an ultra-thin, super-strong, ...

Radio frequency 'harvesting' tech unveiled in UK

An energy harvesting technology that its developers say will be able to turn ambient radio frequency waves into usable electricity to charge low power devices was unveiled in London on Wednesday.

Spiraling laser pulses could change the nature of graphene

A new study predicts that researchers could use spiraling pulses of laser light to change the nature of graphene, turning it from a metal into an insulator and giving it other peculiar properties that might be used to encode ...

Determining the quantum geometry of a crystal

Geometrical phases occur in many places in nature. One of the simplest examples is the Foucault pendulum: a tall pendulum free to swing in any vertical plane. Due to the earth rotation, the actual plane of swing rotates relative ...
