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 ...

Graphene's 'quantum leap' takes electronics a step closer

(PhysOrg.com) -- Writing in the journal Nature Physics, the academics, who discovered the world's thinnest material at The University of Manchester in 2004, have revealed more about its electronic properties.

A light-powered catalyst could be key for hydrogen economy

Rice University researchers have engineered a key light-activated nanomaterial for the hydrogen economy. Using only inexpensive raw materials, a team from Rice's Laboratory for Nanophotonics, Syzygy Plasmonics Inc. and Princeton ...

Researchers add porous envelope to aluminum plasmonics

When Rice University chemist and engineer Hossein Robatjazi set out to marry a molecular sieve called MOF to a plasmonic aluminum nanoparticle two years ago, he never imagined the key would be the same process nature uses ...

Study shows how to get sprayed metal coatings to stick

When bonding two pieces of metal, either the metals must melt a bit where they meet or some molten metal must be introduced between the pieces. A solid bond then forms when the metal solidifies again. But researchers at MIT ...

Exceptionally strong and lightweight new metal created

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ...

Physicists create tabletop antimatter 'gun'

(Phys.org) —An international team of physicists working at the University of Michigan has succeeded in building a tabletop antimatter "gun" capable of spewing short bursts of positrons. In their paper published in the journal ...
