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 ...

Hot electrons do the impossible in catalytic chemistry

(Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts ...

Controlling streams of liquid metal at room temperature

Researchers from North Carolina State University have demonstrated a technique that allows them to produce streams of liquid metal at room temperature. By applying a low voltage to the liquid metal, the researchers were able ...

Gas storage method could help next-generation clean energy vehicles

A research team led by Northwestern University has designed and synthesized new materials with ultrahigh porosity and surface area for the storage of hydrogen and methane for fuel cell-powered vehicles. These gases are attractive ...

Semimetals are high conductors

Researchers in China and at UC Davis have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room ...

1 + 1 does not equal 2 for graphene-like 2-D materials

Physicists from the University of Sheffield have discovered that when two atomically thin graphene-like materials are placed on top of each other their properties change, and a material with novel hybrid properties emerges, ...
