MADISON, WI—University of Wisconsin–Madison researchers have made a material that can transition from an electricity-transmitting metal to a nonconducting insulating material without changing its ...

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 ...

(Nanowerk Spotlight) Polymers are ideal for energy storage for transportation due to their light weight, scalability, low-cost manufacturing, and high dielectric strength. Dielectrics are materials ...

Porcelain insulators have long been integral to electrical power systems, valued for their high dielectric strength, durability and reliability under challenging environmental conditions. Their ...

Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

Researchers are analyzing new materials for electrical insulation, or packaging, that can remove heat more effectively compared to today's insulation, amid a need to redesign our electrical ...

2D semiconductors (such as graphene) could revolutionize electronics: They can be used to produce extremely small transistors. However, in order to make a transistor, insulators are required too. So ...

In a surprising discovery, Princeton physicists have observed an unexpected quantum behavior in an insulator made from a material called tungsten ditelluride. This phenomenon, known as quantum ...

They don’t call graphene a “wonder material” for nothing – it’s ultra-thin, ultra-strong, and has some weird electrical properties. MIT researchers previously found a particularly strange pattern ...

Conductors are materials that allow electric current to flow with minimal resistance and are essential for transmitting power and electrical signals in electronic devices. Most metals are good ...
