Hydrogen Evolution Reaction on Nanostructures Electrodes—a Scenario on Stepped Silver Surfaces
(Springer New York LLC, 2017-11)
We have investigated the scenario for the hydrogen evolution reaction at stepped silver surfaces in acid solutions at high overpotentials using a simple kinetic model. Two independent types of sites, at the steps and at ...
Kinetics of the hydrogen oxidation reaction on nanostructured rhodium electrodes in alkaline solution
(Elsevier Science, 2015-06)
The hydrogen oxidation reaction was studied on a nanostructured rhodium electrode at different rotation rates in alkaline solution. The electrode was prepared via sputtering on a glassy carbon disc support and it was ...
Butia Yatay coconut oil: Process development for biodiesel production and kinetics of esterification with ethanol
The aim of this work is to study biodiesel production using Butia Yatay coconut oil. This oil has acid values between 109 and 140 mg KOH/g, and phosphorus content in the order of 600 ppm. A three-step degumming pre-treatment ...
Thermogravimetric studies of the decomposition kinetics of four different Hevea rubber clones using Ozawa's approach
Thermal degradation of natural rubber extracted from four different rubber clones of the Hevea brasiliensis species was investigated by thermogravimetry using Ozawa's approach to assess the kinetic parameters of the ...
Modeling a new fixed-time batch approach for Mo(VI) determination

Characterization and kinetic study of a nanostructured rhodium electrode for the hydrogen oxidation reaction
The hydrogen oxidation reaction was studied on a nanostructured rhodium electrode at different rotation rates. The electrode was prepared via sputtering on a glassy carbon disc support and it was characterized by X-ray ...
Suicide nucleophilic attack: Reactions of benzohydroxamate anion with bis(2,4-dinitrophenyl) phosphate
(Chemical Equation Presented) The reaction between the benzohydroxamate anion (BHO-) and bis(2,4-dinitrophenyl)phosphate (BDNPP) has been examined kinetically, and the products were characterized by mass and NMR spectroscopy. ...
Martensite decomposition in Cu-Al-Mn-Ag alloys
(Elsevier B.V., 2014-12-05)
The influence of Mn and Ag additions on the isothermal kinetics of martensite decomposition in the Cu-9wt.%Al alloy was studied using X-ray diffractometry (XRD), scanning electron microscopy (SEM), energy dispersive X-ray ...
