Mild oxidation catalysts are used to product a wide range industrial chemicals from hydrocarbons, whereas deep oxidation catalysts yield CO2 and are becomi... S Hansen,J Otamiri,JO Bovin,... - 《Nature》 被引量: 72发表: 1988年 Uptake of NO Gas by YBa2Cu3Oy A large quantity (2.5–3 ...
Broadly, the content of oxygen-containing functional groups increases with the activation temperature, but the high-temperature activation in CO2 reduces the number of oxygen-containing functional groups on the surface of carbon materials [55]. Physical activation has the advantages of a simple ...
Diffusion-controlled reaction of O2•- with NO• radicals produces the potent oxidant peroxynitrous acid (ONOOH) [13], [14], which is in equilibrium with its anion form (ONOO-) at physiological pH values (this mixture is designated ONOOH from hereon, as the acid form is the more ...
Although it is known that both H 2O and CO 2 reduce the catalytic activity of CaO, the kinetics of NO formation catalysed by CaO are often obtained without the presence of H 2O or CO 2. In this work, the catalytic activity for NH 3 oxidation with three types of calcined limestone was...
The binding energies of oxygen, CO, NO, and of the oxidation products CO2and NO2are all markedly enhanced on Ptxcompared to Pt(111), and they trend toward the Pt(111) levels as cluster size increases. Because of the strong interaction of both the reactants and products with the Ptx...
The Nuclear Import of RCC1 Requires a Specific Nuclear Localization Sequence Receptor, Karyopherin α3/Qip The alsSD operon required for acetoin formation is strongly induced in the presence of organic acids; however, no acetoin formation was observed. The ... B Talcott,MS Moore - 《Journal of...
Oxy-fuel combustion is the most effective technology in CO2 emission control.The mercury speciation in oxy-combustion flue gas,especially the influence of high content H2 O and CO2 on the chemical reactions among the flue gas oxidative components(SO3,SO2,NO,NO2,HCl,O2,CO),as well as the in...

(KO level) of metagenome and metatranscriptome libraries (B). In boxplots, boxes are defined by the upper and lower interquartile; the median is represented as a horizontal line within the boxes; whiskers extend to the most extreme data point which is no more than 1.5 times the inter...
reported the chemoselective sulfur oxygenation of various phosphoroamidates, thionophosphates, and thiophosphates using perfluorinated oxaziridine 80 (Equation 6; Table 7) <1995T7981>. Treatment of sulfide 126 with 1 equiv of oxaziridine 80 gave the corresponding sulfoxide in >98% yield, and with ...
