Over the years, Hendrix has maintained that porcelain insulators (and porcelain spacers) should not be used with covered conductor. This is due to the dielectric incompatibility between the two ...

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 ...

Despite significant capital investment by electric utilities in recent years, energy infrastructure across the U.S. received only a C-minus rating in the latest report card from the American Society of ...

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 study takes a new approach to answer a long-standing mystery about insulator-to-metal transitions. Looking only at their subatomic particles, most materials can be placed into one of two ...

Diamond is an effective electrical insulator, but that might not always be the case according to a new study from MIT and Nanyang Technological University (NTU) Singapore. The team has calculated that ...

Fine tuning: a new theoretical framework for controlling a system’s properties using laser beams has been developed. (Courtesy: iStock/Swillklitch) Laser light could turn a normally insulating ...

BUFFALO, N.Y. — Looking only at their subatomic particles, most materials can be placed into one of two categories. Metals — like copper and iron — have free-flowing electrons that allow them to ...
