Understanding friction, the unavoidable enemy

For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and assembly lines.

Transforming common insulators into superior superconductors

Superconductors are a limited group of materials which conduct electricity with zero resistance at lower than certain temperatures (TCs) peculiar to each material. Once zero resistance is achieved, the loss of electric energy ...
