Chemical diffusion (D) and surface exchange (k) coefficients for SrFeO3-delta were measured using an electrochemical cell combined with electrochemical impedance spectroscopy (EIS) and potential step technique (PS) in the temperature range of 850-915°C. A ...
The invention describes a method for electrochem. producing the peroxodisulfuric acid and peroxodisulfates by electrochem. oxidn. of sulfuric acid. The process was carried using on an anode which, preferably, was not completely prepolarized and which was c ...

This work deals with the modelling of electrochemical reactors with bipolar electrodes. We give a numerical model which enables us to compute electrical current and potential distributions in an electrochemical cell of any type of geometry in two and three ...
A consortium was created to investigate electroceramic materials that show ionic or mixed ionic-electronic conduction (MIEC), for application as oxygen separation membranes and in solid oxide fuel cells (SOFC, electrolytes and cathodes). The focus is on de ...
The cathodic properties are discussed of a ZrO2 layer formed on Zr by thermal treatment and by anodic oxidn. The electrosynthesis of ammonium peroxydisulfate (2SO42- .dblarw. S2O82- + 2e-) for which the cathodic redn. of persulfate to sulfate is the undesi ...
This paper describes the selective recovery of heavy metals from a chloride contg. soln. The goal is to recover each heavy metal with high purity and yield by electrodeposition. The soln. contains four different heavy metals (Zn, Pb, Cu and Cd), high amts. ...
Electrochemistry can bring important contributions to current applications, such as organic synthesis or wastewater treatment. In an environmental context, electrochemical processes are interesting substitutes to the conventional wastewater treatment techn ...
A series of novel, surface-active, inorganometallic complexes of osmium were synthesized and then characterized (using electrochemical techniques) as electron transfer mediators for glucose oxidase (EC 1.1.3.4, GOD) from Aspergillus niger. The mediators co ...
