The enzyme activity of alcohol dehydrogenases 4W6Z and 1MG5 demonstrated good agreement with the calculated a-carbon atomic partial charges of the substrates. The correlation coefficients were found to be more than 0.8 (n = 9) for both the oxidation and reduction reactions. The stereo structure of cinnamylalcohol dehydrogenase (ELI3-2) was constructed modification in 1PIW (cinnamyl alcohol dehy...

Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

Attempts to obtain experimental values for the kinetic parameters of phenanthridine oxidation by guinea pig or rabbit liver aldehyde oxidase using common spectrophotometric methods have not been successful due to a lower limit of detection. In the present study, a new spectrofluorimetric assay in combination with a multivariate calibration method for enzymatic kinetic study of aldehyde oxidase ...

Commercially available gases contain residual impurities leading to a background oxygen partial pressure of typically several 10 bar, independent of temperature. This oxygen partial pressure is inappropriate for the growth of some single crystals where the desired oxidation state possesses a narrow stability field. Equilibrium thermodynamic calculations allow the determination of dynamic atmosp...

Thermal oxidation process of silicon carbide (SiC) has been studied by performing in-situ spectroscopic ellipsometry. In our previous work, we, for the first time, found that the growth rates of SiC(0001̄) C-face at oxidation thicknesses less than around 20 nm are much higher than those given by the Deal-Grove (D-G) model. In this report, we show that such a growth rate enhancement occurs also i...

Partial oxidation of alcohols is a topic of great interest in the field of gold catalysis. In this work, we provide evidence that the partial oxidation of allyl alcohol to its corresponding aldehyde, acrolein, over oxygen-precovered gold surfaces occurs via multiple reaction pathways. Utilizing temperature-programmed desorption (TPD) with isotopically labeled water and oxygen species, reactive ...

This paper describes experiments on the effect of the oxidation-reduction state of the respiratory carriers in fragments of mitochondria on three partial or intermediate reactions of the oxidative phosphorylation mechanism which occur in the absence of net electron transport, namely the adenosine 5’-triphosphateinorganic Pa2 exchange reaction (I), the ATPase and dinitrophenol-stimulated ATPase ...

Operando 5D X-ray diffraction imaging reveals complex heterogeneities across multiple length scales in a catalytic reactor for the partial oxidation of methane reaction.
