Electrical insulation materials play a pivotal role in ensuring the safety, efficiency, and longevity of electrical systems.

It hardly conducts any electricity at all, so we can say it’s an electrical insulator. Inside the plastic, all the electrons are tightly bound to the atoms, so the charges cannot move very far ...

Researchers have highlighted that good thermoelectric materials are those that conduct electricity well on the one hand, but ...

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 ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Air is an exceptionally good electrical insulator. To get electricity to easily flow through something, you either need electrons that are not directly tied to any atom or molecule (so-called ...

One thing that has eluded scientists, though, is exactly how a bolt of lightning is initiated. Air is an exceptionally good electrical insulator. To get electricity to easily flow through something, ...
