The current study focuses on the photocatalytic oxidation of benzyl alcohol in acetonitrile under air bubbling conditions comparing titania-based materials, Cu–MOF, and Cu–MOF–NH2 as semiconductor photocatalysts. catalysts were characterized by XRD, N2 adsorption–desorption isotherm, FTIR, Raman spectroscopy, TEM. conversion reached ~100% after exposing four prepared to a 125 W mercury lamp for...

Irradiation with ultrasound (US) and use of an enzyme (E) as pretreatment techniques were carried out to treat a complex effluent (distillery wastewater). These two techniques have been used alone as well as in combination and the efficacy of these techniques was tested by subjecting the effluent to subsequent aerobic biological oxidation (AO). When used alone, US exposure for 30 min and 2 h yi...

conclusions according to the results of the present study, aerobic exercise at moderate intensity and proper time can be considered as a special treatment to prevent diabetes complications and related disorders, particularly obesity. objectives this study aimed to determine whether in patients with type 2 diabetes, substrate oxidation and energy expenditure were affected by the type of intensit...

The purpose of our study was to investigate whether the Trp64Arg polymorphism in beta3-AR gene and the -3826A/G polymorphism in the UCP1 gene were associated with the reduction in energy expenditure and fat oxidation both in resting and aerobic exercise in Japanese. Eighty-six nonobese young healthy Japanese were recruited. Energy expenditure was measured using indirect calorimetry. The subject...

Metal organic frameworks (MOFs) are porous crystalline solids whose constituted by metal ions/nodes with rigid linkers leading to the formation of materials having high surface area and pore volume. One unique features MOFs is presence coordinatively unsaturated sites in their lattice that can act as Lewis acid promoting transformations, including aerobic oxidation reactions various substrates ...

well faceted cuo nanoparticles, were synthesized by thermal-assisted dissociation method at reflux temperature in a short period of time. a possible mechanism for synthesis of such highly pure and stable nanoparticles is tentatively proposed by ft-ir study. the large surface area and rich exposed active sites are expected to endow such nanoparticles with excellent performances in catalysis as d...

Hummingbirds and nectarivorous bats in flight display some of the highest rates of aerobic metabolism among vertebrates. Analysis of the pathway of oxygen, i.e., the “oxygen transport cascade”, reveals the concerted upregulation of capacities for O2 flux from the external environment, through the respiratory and cardiovascular systems, into muscle mitochondria. Pathways for aerobic energy metab...

Horseradish peroxidase has been shown to catalyze the oxidation of veratryl alcohol (3,4-dimethoxybenzyl alcohol) and benzyl alcohol to the respective aldehydes in the presence of reduced glutathione, MnC12, and an organic acid metal chelator such as lactate. The oxidation is most likely the result of hydrogen abstraction from the benzylic carbon of the substrate alcohol leading to eventual dis...
