Quantitative Determination of the Number of Surface Active Sites and the Turnover Frequencies for Methanol Oxidation over Metal Oxide Catalysts: Application to Bulk Metal Molybdates and Pure Metal Oxide Catalysts
(Academic Press Inc Elsevier Science, 2001-09-23)
The present work investigates the number and nature of the surface active sites and the catalytic activity of bulk metal molybdates and bulk metal oxides on methanol selective oxidation. Bulk metal molybdates were synthesized ...
Oxidation of chalcopyrite by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans in shake flasks
(Elsevier B.V., 2002-12-02)
Chalcopyrite oxidation was evaluated with two acidophilic thiobacilli that are important in bioleaching processes. Acidithiobacillus thiooxidans in pure culture did not oxidize CuFeS2 but oxidized externally added S in the ...
Thermal treatments of precursors of molybdenum and vanadium oxides and the formed MoxVyOz phases active in the oxydehydration of glycerol
(2017-02-25)
This paper presents an in situ study of the crystallographic phases formed during the thermal treatment of precursors of vanadium and molybdenum oxides, measured under synchrotron X-ray diffraction. The interest in the ...
Ilex paraguariensis supplementation may be an effective nutritional approach to modulate oxidative stress during perimenopause
(2017-04-01)
Perimenopause is a period in a woman's life that precedes menopause and is characterized by hormonal changes that result in increased oxidative stress. Since oxidative stress is associated with age-related diseases and ...
Chemical evolution in the asteraceae. the oxidation - Reduction mechanism and production of secondary metabolites
(2006-01-01)
This work describes the application of partial least squares (PLS) regression to variables that represent the oxidation data of several types of secondary metabolite isolated from the family Asteraceae. The oxidation states ...
Chemical evolution in the Asteraceae. The Oxidation-Reduction mechanism and production of secondary metabolites
(Natural Products Inc, 2006-01-01)
This work describes the application of partial least squares (PLS) regression to variables that represent the oxidation data of several types of secondary metabolite isolated from the family Asteraceae. The oxidation states ...
Quantitative determination of the number of surface active sites and the turnover frequency for methanol oxidation over bulk metal vanadates
(Elsevier Science, 2003-02)
The present work investigates the number and nature of the surface active sites, selectivity and turnover frequency towards methanol selective oxidation of a series of bulk metal vanadates. The catalysts were synthesized ...
Leishmaniasis causes oxidative stress and alteration of oxidative metabolism and viability of neutrophils in dogs
(2013-09-30)
The aim of the present study was to test the hypothesis that oxidative stress and alteration of oxidative metabolism and apoptosis of neutrophils in dogs vary with the stage of leishmaniasis and to determine the contribution ...
