Quantification of active sites for the determination of methanol oxidation turn-over frequencies using methanol chemisorption and in situ infrared techniques. 1: Supported metal oxide catalysts
(American Chemical Society, 2001-10)
Methanol oxidation over metal oxide catalysts is industrially important for the production of formaldehyde, but knowledge about the intrinsic catalysis taking place is often obscured by a lack of knowledge as to the number ...
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 ...
Transition metal oxides in the electrocatalytic oxidation of methanol and ethanol on noble metal nanoparticles
(2017-08-01)
In this contribution, we briefly describe the papers published over the past two years regarding the effects of transition metal oxides, utilized either as supports or as co-catalysts, on the electrochemical oxidation of ...
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, ...
Development of an electrochemical sensor based on nanostructured hausmannite-type manganese oxide for detection of sodium ions
(2013-03-25)
The preparation and electrochemical characterization of hausmannite-type manganese oxide to use as a sensing material for sodium ion is described. This paper reports a new via synthetic to obtain of the hausmannite-type ...

Time course and mechanism of brain oxidative stress and damage for redox active and inactive transition metals overload
(Instituto de Histología y Embriología, 2016-04)
The objective of this work was to study the in vivo time course of biochemical processes of oxidative damage in the brain of Sprague-Dawley rats that received an acute overload of the redox active metals iron (Fe) and ...
Characterization of the anodic growth and dissolution of oxide films on valve metals
(Elsevier Science Inc, 2008-03)
Chemical dissolution processes coupled to anodic oxide growth taking place by a "high-field" conduction mechanism, are considered. The equation for the steady-state current density obtained during potentiodynamic polarization ...
