With contributions from Barbara Bain, in Dacie and Lewis Practical Haematology (Tenth Edition), 2006 Equipment and Reagents A vertical gel electrophoresis tank with appropriate plates, combs, and spacers. A slab gel dryer with vacuum pump. 40% (w/v) acrylamide solution. Caution: Acrylamide is ...
Lewis acidic centersOxygen vacancyThe physico-chemical properties of primary alcohol conversion catalysts SnO 2, CeO 2 and tin dioxide modified with rhodium, cerium or both, are presented. The synthesis of pure SnO 2 was performed with the Okazaky method. Admixturing with rhodium was made by ...

(e) An example of a suitable blowing agent for the production of cellular moldings is water, which reacts with isocyanate groups to form carbon dioxide. The water can be employed here in pure form or in chemically or physically bound form, for example in the form of tert.-butanol, as wa...
233 Although the catalyst allowed fast conversions, high selectivity for amines and alcohols with various structures in an Ar atmosphere in o-xylene, the base (NaOH) and Lewis acidic (CaCl2) cocatalysts were required. Additionally, the catalyst still has a stable catalytic activity after two ...
In the formation of this adduct, the Lewis acidity plays an important role, with the interaction between the catalyst and the oxidant being an acid–base interaction. [45] When we compare the acid sites and the amount of these sites in the catalyst, it is possible to conclude that the ...
