Scientific debate has been hot lately about whether microbial nanowires, the specialized electrical pili of the mud-dwelling anaerobic bacterium Geobacter sulfurreducens, truly possess metallic-like ...

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, ...

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 ...

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 ...

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 ...

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, ...

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 ...
