81Fermi surface — In condensed matter physics, the Fermi surface is an abstract boundary useful for predicting the thermal, electrical, magnetic, and optical properties of metals, semimetals, and doped semiconductors. The shape of the Fermi surface is derived from …
82Isobaric speakers — The Isobaric or isobarik loudspeaker construction technique was originally introduced by Harry F. Olson in the early 1950s. It is derived from the term Isobaric, which is of Greek origin: Iso meaning constant and Baric meaning pressure . It… …
83Nuclear magnetic resonance spectroscopy — A 900MHz NMR instrument with a 21.2 T magnet at HWB NMR, Birmingham, UK Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei… …
84Polarization — ( Brit. polarisation) is a property of waves that describes the orientation of their oscillations. For transverse waves, it describes the orientation of the oscillations in the plane perpendicular to the wave s direction of travel. Longitudinal… …
85Magnetic susceptibility — In electromagnetism, the magnetic susceptibility χm (latin: susceptibilis “receptiveness”) is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. A related… …
86Inductrack — is a completely passive, fail safe magnetic levitation system, using only unpowered loops of wire in the track and permanent magnets (arranged into Halbach arrays) on the vehicle to achieve magnetic levitation. The track can be in one of two… …
87Maglev (transport) — MAGLEV, or magnetic levitation, is a system of transportation that suspends, guides and (usually) propels vehicles, predominantly trains, using magnetic forces. This method has the potential to be faster, quieter and smoother than wheeled mass… …
88vacuum technology — Introduction all processes and physical measurements carried out under conditions of below normal atmospheric pressure. A process or physical measurement is generally performed in a vacuum for one of the following reasons: (1) to remove the …
89reaction — 1. The response of a muscle or other living tissue or organism to a stimulus. 2. The color change effected in litmus and certain other organic pigments by contact with substances such as acids or alkalies; also the property that such substances… …
