Metal end fittings are selected from a wide range of available standards ... giving a long internal creepage path that is free from moisture. Although standard insulator designs are available, it is ...

Experiment has now proved the existence of the predicted three-dimensional 'topological insulator' in the semiconducting alloy Bi 1−x Sb x. One of the triumphs of quantum mechanics in the ...

For electricity to flow, you need a conductor. That plastic bottle, that’s an insulator, they don’t let electricity pass through. No, not that either, wood’s an insulator too. We’ve got to ...
