Quantitative determination of the number of active surface sites and the turnover frequencies for methanol oxidation over metal oxide catalysts: I. Fundamentals of the methanol chemisorption technique and application to monolayer supported molybdenum oxide catalysts
(Elsevier Science, 2000-11)
A detailed study of the methanol chemisorption and oxidation processes on oxide surfaces allowed the development of a method to quantify the number of surface active sites (Ns) of metal oxide catalysts. In situ infrared ...
Influence of metallic oxides on ethanol oxidation
(Elsevier, 2014-05-27)
An improvement in ethanol oxidation electrocatalysis is possible with multifunctional Ptbased combinations. Thus, the addition to Pt of Sn, Ir or Ni enhances the ethanol oxidation reaction (EO) and shifts the onset oxidation ...
Antioxidative mechanisms protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage
(Wiley, 2010-12)
The aim of this investigation was to determine whether the antioxidant defences protect resistant strains of Staphylococcus aureus against ciprofloxacin oxidative damage. Reactive oxygen species (ROS) were determined by ...
Peroxidase activity in Malpighian tubules of Triatoma infestans Klug
(Faculty Press, 1998-01-01)
Benzidine and diamino benzidine (DAB) oxidation, typically performed by peroxidases, was demonstrated by light and electron microscopy in peroxisomes, mitochondria and membranous structures which occurred in close contact ...

Nitric oxide and membrane lipid peroxidation in photosynthetic and non-photosynthetic organisms after oxidative stress exposure
(Frontiers, 2013-08)
Oxidative damage to lipids was characterized in terms of the nature of the oxidant, the type of lipid, and the severity of the oxidation (Simontacchi et al., 2011). Even though malondialdehyde detection with the thiobarbituric ...
Characterization of anodic growth and dissolution of antimony oxide films
(Elsevier Science Sa, 2009-07)
The anodic growth, morphology and stability of antimony oxide films grown in buffered phosphate electrolytes has been characterized by electrochemical methods, in situ ellipsometry and atomic force microscopy. The anodic ...
Nitric oxide and metals toxicity
(Research Singpost, 2007)
Numerous studies, focusing on the effects of environmental pollutants such as metals of industrial use, appear to affect intracellular homeostasis, particularly cadmium, arsenic mercury, nickel, chromium, manganese, copper, ...
