Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional ...

When your winter jacket slows heat escaping your body or the cardboard sleeve on your coffee keeps heat from reaching your ...

Normally metals and insulators sit at opposite ends of a spectrum of conductivity, but researchers have discovered a material that can switch between those states freely, even at room temperature. The ...

University of Cambridge researchers have discovered that a material already known for its peculiar electrical properties appears to behave as both a conductor and an insulator at the same time. This ...

Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely ...

An optical analogue of a topological insulator has been created by physicists based in Israel and Germany. Consisting of an array of helical waveguides, light cannot propagate between waveguides in ...

Metals are compounds that are capable of conducting the flow of electrons that make up an electric current. Other materials, called insulators, are not capable of conducting an electric current. At ...

An essential requirement for ensuring worker safety when performing live work with transmission composite insulators (also called polymer or nonceramic insulators) is ...

More than a century after the cable-style “Mickey Mouse” insulator was introduced, a Chicago-area lineman has introduced a new take on the vintage porcelain insulators. “Linemen love the Mickey Mouse ...
