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 ...

Researchers have assiduously studied the relationship between insulators and conductors. The international team has extensively tested layered hexagonal boron nitride (h-BN) – an insulating ...

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

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 ...

Introduction Electricity powers many of the devices you use every day. Those devices are made up of circuits, ranging from very simple (such as a lamp with a single lightbulb) to very complex (such as ...

The need to integrate renewable energy resources, and prepare for increased demand for power as electrification takes hold in transportation and other sectors, creates challenges for an aging grid.

More efficient computers and other devices often begin with new materials. One promising option is vanadium dioxide, which rapidly transforms from an insulator to a conductor in femtoseconds.
