THE discussion at the York meeting of the British Association on the electric supra-conductivity of metals was opened by a reference to the classical experiments of Dewar and Fleming 1 made in 1893 on ...

When the free electrons absorb heat energy, they move much faster. As they move through the metal, free electrons crash into metal ions. This process is very much faster than conduction caused by just ...

The prospect of electronics at the nanoscale may be even more promising with the first observation of metallic conductance in ferroelectric nanodomains. The prospect of electronics at the nanoscale ...

RICHLAND, Wash.—A common carbon compound is enabling remarkable performance enhancements when mixed in just the right proportion with copper to make electrical wires. It’s a phenomenon that defies ...

A new experiment offers the cleanest proof yet for magnetism-driven transitions of metals to insulators. Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying ...

Technical ceramics are used in many applications where traditional materials such as steel or plastic are ineffective or unsuitable. For many of these applications, extreme hardness, wear resistance, ...

Conduction occurs in solids. Metals are good conductors. Non-metals and gases are usually poor conductors. Poor conductors are called insulators. Heat energy is conducted from the hot end of an object ...

A common carbon compound is enabling remarkable performance enhancements when mixed in just the right proportion with copper to make electrical wires. It’s a phenomenon that defies conventional wisdom ...

An illustration of two domains (blue and orange) divided by a domain wall (white area) in a material. The magnetic order is designated with organized arrows (electron spins) while the colors represent ...
