Zone melting (or zone refining, or floating-zone method, or floating-zone technique) is a group of similar methods of purifying crystals, in which a narrow region of a crystal is melted, and this molten zone is moved through the crystal. The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified ...
Area code 212 is one of the original North American area codes assigned by AT&T in 1947, originally serving all five boroughs of New York City.Area codes were assigned based on the volume of traffic and the speed of dialing the code on a rotary electromechanical dial phone, so that the higher the volume of traffic, the less time it took to dial the area code.
Float-zone silicon is very pure silicon obtained by vertical zone melting. The process was developed at Bell Labs by Henry Theuerer in 1955 as a modification of a method developed by William Gardner Pfann for germanium. In the vertical configuration molten silicon has sufficient surface tension to keep the charge from separating.
The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. [1] Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."
Laser-heated pedestal growth (LHPG) or laser floating zone (LFZ) is a crystal growth technique. A narrow region of a crystal is melted with a powerful CO2 or YAG laser. The laser and hence the floating zone, is moved along the crystal. The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind it.

Link - An alternative name (alias) which links to a canonical zone. Link † - A standard Link (as above). The dagger symbol (†) signifies that the zone was canonical in a previous version of the database. Historical data for such zones is still preserved in the source code, but it is not included when compiling the database with standard ...
