Advanced Materials

Advanced Materials is a weekly peer-reviewed scientific journal covering materials science. It includes Communications, Reviews, and Feature Articles on topics in chemistry, physics, nanotechnology, ceramics, metallurgy, and biomaterials.

History

The journal was founded in 1988 as a supplement in the general chemistry journal Angewandte Chemie and remained in that journal for the first 18 months of its existence. The Founding Editor was Peter Goelitz (the Editor of Angewandte Chemie). The current editor-in-chief is Peter Gregory. The editorial office is in Weinheim, Germany.

Originally published 12 issues per year (monthly), the journal switched to 15 issues in 1997, 18 issues in 1998, and 24 issues (biweekly) in 2000; in 2009, the journal saw further expansion and became to publish weekly, with 48 issues per year.

Frequent topics covered by the journal also include liquid crystals, semiconductors, superconductors, optics, lasers, sensors, mesoporous materials, shape memory alloys, light-emitting materials, magnetic materials, thin films, and colloids.

GE Aviation

GE Aviation, a subsidiary of General Electric, is headquartered in Evendale, Ohio, outside Cincinnati. GE Aviation is among the top aircraft engine suppliers, and offers engines for the majority of commercial aircraft. GE Aviation is part of the General Electric conglomerate, which is one of the world's largest corporations. The division operated under the name of General Electric Aircraft Engines (GEAE) until September 2005.

GE Aviation's main competitors in the engine market are Rolls-Royce and Pratt & Whitney. GE operates a joint venture with Snecma of France, CFM International.

History

Early efforts

General Electric had a long history in steam turbine work, dating back to the 1900s. In 1903 they hired Sanford Alexander Moss, who, in time, started the development of turbosuperchargers at GE. This led to a series of record-breaking flights over the next ten years. At first the role of high-altitude flight was limited, but in the years immediately prior to WWII they became standard equipment on practically all military aircraft. GE was a world leader in this technology; most other firms concentrated on the mechanically simpler supercharger driven by the engine itself, while GE had spent considerable effort developing the exhaust driven turbo system that offered higher performance.
