ORNL superconducting wire yields unprecedented performance

(Phys.org) —The ability to control nanoscale imperfections in superconducting wires results in materials with unparalleled and customized performance, according to a new study from the Department of Energy's Oak Ridge National ...

Three layers of graphene reveals a new kind of magnet

Metals have a large density of electrons and to be able to see the wave nature of electrons one has to make metallic wires that are only a few atoms wide. However, in graphene - one atom thick graphite—the density of electrons ...

Nature still sets standard for nanoscience revolution

(PhysOrg.com) -- By striving for control and perfection in everything from computer chips to commercial jets, scientists and engineers actually exclude a fundamental force that allows nature to outperform even their best ...

Metamaterial built from gears

A specifically designed collection of gears is soft on one end and rigid on the other. These robust properties hold even in the event of manufacturing imperfections. This emerging research may lead to new ways of designing ...

Making quantum cryptography truly secure

Quantum key distribution (QKD) is an advanced tool for secure computer-based interactions, providing confidential communication between two remote parties by enabling them to construct a shared secret key during the course ...

'Cleaning' boosts solar cell efficiency

Energy losses in nanowire solar cell can be significantly reduced by 'cleaning' the surface of the cells with a special etching method. This has been shown by researchers at Eindhoven University of Technology (TU/e), Delft ...

Scientists find unusual electrons that go with the flow

On a quest to discover new states of matter, a team of Princeton University scientists has found that electrons on the surface of specific materials act like miniature superheroes, relentlessly dodging the cliff-like obstacles ...
