Oxides correlated

The classical kinetic resolution of racemic substrate precursors allows only access to a theoretical 50% yield of the chiral ladone product, while the antipodal starting material remains unchanged in enantiomerically pure form. The regioseledivity for the enzymatic oxidation correlates to the chemical readion with preferred and exclusive migration of the more nucleophilic center (usually the higher substituted a-carbon). The majority of cydoketone converting BVMOs (in particular CHMOAdneto)...

Exhaled nitric oxide was used as the marker of airway inflammation after patients who had asthma were found to have increased levels of exhaled nitric oxide and nitric oxide synthase expression [17]. Exhaled nitric oxide correlated with a response to steroid, defined as change in pulmonary function testing, asthma symptoms, and BHR [18]. Patients who have symptoms of asthma who respond to steroids have higher exhaled nitric oxide than those who do not, implying inadequate anti-inflammatory treatment. The cutoff of exhaled nitric oxide for steroid response was determined to be approximately 48 parts per billion in one study [18], but no standards are widely used.

It has been demonstrated that the Brunaver, Emmett and Teller (BET) specific surface area of magnesium oxide correlates well with its thickening activity, while for magnesium hydroxide particle size correlates with thickening activity (Casey et al., 1989). 

It is clear that the most active catalysts for oxidation of olefins to CO 2 are composed of transition elements that form readily reducible oxides. Correlation with heats of formation or, better, with heats of removal of a differential amount of oxygen in the operating state, appears at present to offer more promise for rationalization of activities than correlations with d electron configurations or with semiconductor properties. 

It is of interest to link ki to the rate of hydrogen peroxide decomposition. As shown in Figure 17.5, for a constant pH, the rate of oxidation correlates well with the rate of H2O2 decomposition. This observation is consistent with the idea of the presence of two channels for oxidation involving oxygen, and hydrogen peroxide as the second electron acceptor. The total rate of methyl viologen oxidation is the sum of the reaction rates in these two channels ... 

Fuger (1985,1992) has summarized the experimental enthalpies of complexation of hexavalent actinide oxides with alkali-metal and alkaline-earth oxides in terms of the basicities of the alkali-metal and alkaline-earth oxides. Using Smith s (1987) acid-base oxide correlations (section 4.1.1), Morss and Williams (1992) placed these enthalpies on a quantitative scale to derive oxide acidity for UOj. 

As can be seen in Table 11.1, noble metals Pt, Pd, and Rh are the most usable catalysts in calorimetric gas sensors designed. It was established that of all the catalysts known they have the highest activity with respect to oxidation of combustible gases (see Fig. 11.2) and provide acceptable operation temperatures. Morooka and coworkers (Morooka and Ozaki 1966 Morooka et al. 1967) showed that activity for a model reaction, propylene oxidation, correlates with the strength of the metal-oxygen (M-0) bond. Because an LEL sensor must oxidize all ambient hydrocarbon species, the highest activity catalysts hold the most promise for the application. Therefore, the choice of palladium and platinum and sometimes rhodium for application in combustion gas sensors is natural (Miller 2001). This explains why the automobile exhaust system is treated with platinum or palladium compounds and is called a catalytic converter.
