Note: In the Gold Book, [1] the terms “active center” and “active site” are defined with reference to heterogeneous catalysis and the term “reactive site” is used within the definition of chain polymerization.
Similarly to what is witnessed in conventional reactive sputter deposition process, HiPIMS has also been used to attain oxide or nitride-based films on several substrates, as is seen in the list below. However, as it is characteristic of these methods, the performance of such depositions has significant hysteresis and need to be carefully ...
A reactive center, also called a propagating center, in chemistry is a particular location, usually an atom, within a chemical compound that is the likely center of a ...
In this equation, P is the polymer while x represents degree of polymerization, * means active center of chain-growth polymerization, M is the monomer which will react with active center, and L may be a low-molar-mass by-product obtained during chain propagation. For most chain-growth polymerizations, there is no by-product L formed.
During initiation, an active center is created from which a polymer chain is generated. Not all monomers are susceptible to all types of initiators. Radical initiation works best on the carbon–carbon double bond of vinyl monomers and the carbon–oxygen double bond in aldehydes and ketones. [1] Initiation has two steps.
The original formulation of functional reactive programming can be found in the ICFP 97 paper Functional Reactive Animation by Conal Elliott and Paul Hudak. [1] FRP has taken many forms since its introduction in 1997. One axis of diversity is discrete vs. continuous semantics. Another axis is how FRP systems can be changed dynamically. [2]
Fujitec Co., Ltd. (フジテック株式会社, Fujitekku Kabushiki-gaisha) is a Japanese elevator manufacturer. Fujitec was founded by late Honorary Chairman, Mr. Shotaro Uchiyama in February 1948 for the purpose of research and development, manufacturing, sales, installation and maintenance of elevators, escalators and travellators.
To investigate these materials, she creates lab-based experiments that can characterize materials properties at ultra high temperatures, flow rates and in the presence of reactive gases. Characterization involves spectroscopy, microscopy and chemical analysis (e.g. thermochemical properties and changes in weight).
