A semiconducting material that performed a quantum "flip" from a conductor to an insulator above room temperature has been developed at the University of Michigan. It potentially brings the world ...

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 ...

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 ...

An Australian-led study has found unusual insulating behavior in a new atomically-thin material—and the ability to switch it on and off. Materials that feature strong interactions between electrons ...

Teach children about conductors and insulators with this bright, engaging and easy-to-read electricity anchor chart and science poster. Designed for learners aged 7–11, this printable resource ...
