Operation Catalyst
Catalysis () is the increase in rate of a chemical reaction due to an added substance known as a catalyst (). Catalysts are not consumed by the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are important factors in reaction rate. Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process of regenerating the catalyst. The rate increase occurs because the catalyst allows the reaction to occur by an alternative mechanism which may be much faster than the noncatalyzed mechanism. However the noncatalyzed mechanism does remain possible, so that the total rate (catalyzed plus noncatalyzed) can only increase in the presence of the catalyst and never decrease. Catalysis may be classified as either homogeneous, whose components are dispersed in the same phase (usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aermacchi MB-326
The Aermacchi or Macchi MB-326 is a light military jet trainer designed and produced by the Italian aircraft manufacter Aermacchi. It is one of the most commercially successful aircraft of its type, being bought by more than 10 countries and produced under licence in Australia, Brazil and South Africa. The MB-326 was developed during a period when "all-through" jet training was considered by many air forces to be the most cost-effective model for training of military pilots. Accordingly, Aermacchi designed it as a single type of aircraft that could readily perform both elementary and advanced training right through to a near combat-ready standard. After it was proposed during the 1950s, the Italian Air Force (AMI) quickly became interested in the MB-326, and an initial contract to produce three prototypes was issued following a competition. Several design refinements were made prior to the AMI, giving its official approval of the project during 1956. On 10 December 1957, the fir ...
