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 ...

Defying conventional scientific knowledge about electrical conductivity, the addition of a common carbon compound to copper to make electrical wires results in significant performance enhancements, ...

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 ...

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 ...

Researchers at the Pacific Northwest National Laboratory (PNNL) are working to increase the conductivity of aluminum, making it economically competitive with copper. In the scientists’ view, this work ...

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 ...

The quest to make metallic hydrogen has been long and arduous. Victory has been declared several times, and sometimes retracted. Scientists predicted hydrogen’s metallic state—which could be useful as ...

The particles of liquids are further apart than solids. This means that most liquids are poor conductors of heat because the frequency of collisions is reduced. The particles of gases are even further ...
