Metal surface can repel electric charges

(Phys.org)—Metals are known for being good electrical conductors. Due to this property, a stationary electric point charge placed outside a metal will cause the electrons in the metal to redistribute in such a way that ...

Material turns 'schizophrenic' on way to superconductivity

(Phys.org) —Rice University physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a material that becomes "schizophrenic"—simultaneously exhibiting the ...

Pair claim they have turned hydrogen to metal

(PhysOrg.com) -- Many have tried, but none have succeeded. For at least a hundred years, scientists looking at hydrogen have scratched their chins when musing over the fact that it, as an alkali metal, by all rights should ...

Researchers make graphene hybrid

Rice University researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.

Magnetism drives metals to insulators in new experiment

Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal ...

To conduct, or to insulate? That is the question

A new study has discovered mysterious behaviour of a material that acts like an insulator in certain measurements, but simultaneously acts like a conductor in others. In an insulator, electrons are largely stuck in one place, ...

From metal to insulator and back again

New work from Carnegie's Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.

Using E-petals for making stretchable metal conductors

The research beat goes on in stretchable electronics. Scientists work on solutions for ultraflexible, stretchable, and wearable electronics and pursue advanced materials toward that end. Dr. Peter Harrop, chairman of market ...
