The International Association of Heat and Frost Insulators and Allied Workers (AWIU or Insulators) is a trade union in the United States and Canada, founded in 1903.It is affiliated with the AFL–CIO and the Canadian Labour Congress and the North America's Building Trades Unions.
2D Topological insulators were first realized in system containing HgTe quantum wells sandwiched between cadmium telluride in 2007.. The first 3D topological insulator to be realized experimentally was Bi 1 − x Sb x.
Victor Insulators, Inc. based in Victor, New York (founded 1893 by Fred M. Locke) is the oldest insulator company in North America. They originally made glass insulators for electrical lines.
Strain insulators on high-voltage power lines. A strain insulator is an electrical insulator that is designed to work in mechanical tension (strain), to withstand the pull of a suspended electrical wire or cable.
Insulator may refer to: . Insulator (electricity), a substance that resists electricity Pin insulator, a device that isolates a wire from a physical support such as a pin on a utility pole
Analogous to Mott insulators we also have to consider superexchange in charge-transfer insulators. One contribution is similar to the Mott case: the hopping of a d electron from one transition metal site to another and then back the same way.
A notable precursor to the Indiana AFL–CIO was the Indiana Federation of Labor. The organization was founded on September 9, 1885; 139 years ago () as the Indiana Federation of Trade and Labour Unions and was, at a point, the oldest operation state federation of labor.
