Alcohol intake or nonalcoholic molecules can increase the levels of CYP3A and CYP2B, although the degree of their elevation is lower than that of CYP2E1 (Johansson et al., 1988; Niemelä et al., 2000). Since CYP3A is responsible for the metabolism of many drugs, it is likely that meta...
the degree of double bond which can be correlated to the reduced oxidation stability of the fuel and so, the fuel instability is directly proportional to the number of double bonds. Generally, the polyunsaturated fatty acids (C18:2, linoleic acid; C18:3 linolenic acid) are most susceptible to...

One must calculate the ratios to assess the oxidation type, as explained in the beginning of this article under Definition Of Fast Oxidation.Degrees of fast oxidation. A rough method to assess the degree of fast oxidation is to use the following criteria:...
The C/H ratio reflects the degree of dehydrogenation and carbonization at high temperatures. The particle size reflects the degree of surface growth. However, the C/H ratio of individual particles is difficult to obtain. In addition, it is not possible to determine the maturity from the ...
Naguib et al. [1] reported the first MXene (Ti3C2Tx) in 2011 by etching Al-based Ti3AlC2MAX in a strong hydrofluoric (HF) acid. The wet etching environment removed the aluminum layers and caused the surface of the MXene sheets to be terminated with functional groups such as =O, –...
Similarly, at constant concentrations of reactants and at other conditions constant, t-butyl alcohol was varied from 0% to 40% (V/V) in the reaction medium. As for ionic strength, changing dielectric constant of the medium had no significant effect on the reaction rate. 3.5. Influence of ...
2. The oxidation process of claim 1 wherein said Oppenauer reaction is carried out with a molar ratio of furfural to allyl alcohol in the range of 3:1 to 1:2. 3. The oxidation process of claim 1 wherein said allyl alcohol is disubstituted with aliphatic groups. ...
In a process for oxidizing a hydrocarbon to a corresponding hydroperoxide, alcohol, ketone, carboxylic acid or dicarboxylic acid, the hydrocarbon is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide of the general formula (I): ...
11.The method of claim 1, wherein the contacting occurs in the presence of a biphasic solvent system comprising a phase transfer catalyst comprising at least one alcohol. 12.12-14. (canceled) 15.The method of claim 1, wherein the pH of the composition is maintained between about 4.0 and ...
