Nickel hydroxide films in contact with an electroactive solution. A study employing electrochemical impedance measurements
(AIRCC Publishing Corporation, 2016-02)
The deactivation of nickel hydroxide films after prolonged storage times without use was studied. This study was carried out in the context of the Rotating Disc Electrode Voltammetry (RDEV) and<br />Electrochemical Impedance ...
A Study of the Charge Transport Process at Nickel Hydroxide-Gold Modified Electrodes employing Rotating Disc Electrode Voltammetry and Ac Impedance Measurements
(Scienctific Online, 2014-02)
The aim of the present work was study how the charge-transport process of a nickel hydroxide film electrochemically synthesized on a gold substrate is modified when the electrode is stored without use for long time. It was ...
First-principles investigation of Li ion diffusion in Li2FeSiO4
(2013)
We have studied the Li-ion migration and the electrochemical performance of Li2FeSiO4 in the monoclinic crystal structure with P21 symmetry and the related delithiated system LiFeSiO4. For this purpose, the framework of ...

Lithium transport investigation in LixFeSiO4: a promising cathode material
(2013)
In this paper we investigate lithium mobility in both Li2FeSiO4 and its half-lithiated state LiFeSiO4 considering an orthorhombic crystal structure. We find that the calculated activation energy of Li+ ions hopping between ...
Cd(II) biosorption using Lessonia kelps
(Elsevier, 2011)
Lessonia kelps (L. trabeculata and L. nigrescens) have been successfully used for the recovery of Cd(II) from near neutral solutions. The biomass was pre-treated with calcium chloride for stabilization of alginate-based ...
The oxygen reduction reaction in solid oxide fuel cells: From kinetic parameters measurements to electrode design
(IOP Publishing, 2020-10)
The research and development of new Solid Oxide Fuel Cell cathode materials is an area of intense activity. The kinetic coefficients describing the O2-reduction mechanism are the O-ion diffusion (Dchem) and the O-surface ...
