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 ...

It is generally known that most metals conduct electricity. This is because some of the electrons in a so-called conduction band move unhindered through the crystalline lattice. This type of ...

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 ...

Engineers have flipped the picture of the standard polymer insulator, by fabricating thin polymer films that conduct heat -- an ability normally associated with metals. In experiments, they found the ...
