Ian Horrocks,Peter F. Patel-Schneidermolecular addition five membered carbocycles and heterocycles. By non-Kolbe electrolysis carboxylic acids can be converted into ethers, acetals, olefins or acetamides. Rearrangements and fragmentations lead to stereospecifically substituted cyclopentanoids and one- or four-carbon ring extensions.作者: 猛擊 時(shí)間: 2025-3-22 06:45

Electronically conducting polymers,ochemical research results from their unusual charging/discharging properties. In addition, electropolymerization is a challenging method of preparing these materials. Therefore, main topics treated are electropolymerization, the structure, and the charge storage mechanism of conducting polymers. An作者: Heterodoxy 時(shí)間: 2025-3-24 06:29
Chemically modified electrodes, with emphasis on the more recent methods of electrochemical polymerization and on new ion exchanging materials. Surface derivatized electrodes are not treated in detail. The catalysis of electrochemical reactions is treated from the view of theory and of practical application.

Using Artificial Boundaries in the Game of Go, close off an area. This paper describes a new general framework for finding boundaries in a way such that existing local search methods can be used. Furthermore, by using a revised local UCT search method, it is shown experimentally that this framework increases performance on local Go problems wit作者: SHRIK 時(shí)間: 2025-3-25 16:05 作者: 未完成 時(shí)間: 2025-3-25 22:54
