3Superconducting magnetic energy storage — (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. A typical SMES system includes… …
4Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
5food preservation — Any method by which food is protected against spoilage by oxidation, bacteria, molds, and microorganisms. Traditional methods include dehydration, smoking, salting, controlled fermentation (including pickling), and candying; certain spices have… …
