Composite catalysts involving acidic or basic zeolites and gamma-aluminum oxide or silicon dioxide-aluminum oxide and their application to cracking and reforming. (Volumes I and II).The performance of catalysts involving zeolite composite catalysts on catalytic cracking and reforming is examined ...
The transduction is due the formation of and acidic/basic substance as the result of the reaction catalysed by a suitable enzyme immobilised on the PSi surface. Amperometric/voltammetric PSi-based biosensors, instead, measure the current intensity produced by the action of a redox r...
Salt and saw dust is added to infuse air into the product so that it can be broken into pieces easily. The product obtained is first washed with strong acid followed by strong base to remove basic and acidic impurities respectively. Finally, it is washed with water. ...
The evolution of scientific understanding — the Cd behavior in soil and in plant is discussed for the first time. Our analysis evidences that the research on Si-Cd interactions in the soil–plant system has quickened only in recent years, although basic interactions between silicic acid and Cd...
Titanium dioxide is extremely chemically stable and is an acidic amphoteric oxide. It does not react with other elements and compounds at room temperature, and has no effect on oxygen,nitrogen, hydrogen sulfide, carbon dioxide . It is insoluble in water, fat, insolu...
(Guhaet al., 2010; Donget al., 2012). In addition, silicon is Complementary Metal-Oxide-Semiconductor (CMOS) compatible which allows making hybrid circuit which allows combining electronics andoptics(Orcuttet al., 2012; Kitaet al., 2018) as shown inFig. 1(c). However, silicon is a ...
Silicon Dioxide Nanopowder(chemical formula: SiO2) is an acidic oxide, and the corresponding hydrate is silicic acid (H2SiO3). Silica is the most important compound of silicon. The natural silica present on the earth accounts for about 12% of the mass of the...

The company is committed to the R & D, production and service of refractories used in metallurgy, electric power, nonferrous metals, building materials, chemical industry and other industries. Its products cover 198 kinds of materials and 2369 varieties in th...
For instance, several contradictory reports on electrochemical properties, electrocatalytic activity and biological properties of graphene and graphene oxide (GO) were ultimately understood to be the result of metallic impurities or acidic residues7,8,16,17,18,19,20. Such inconsistency prevents the ...
