A photolytic system comprised of a darkened halfcell and an illuminated halfcell in which oxidation and reduction reactions are made to occur. These halfcells are joined by an electrically conductive element and an ion conducting junction for electron tran ...
The influence of potassium on the formation of surface vanadia species on V/Ti oxide catalysts contg. from 0.2 to 5 monolayers of vanadia (K/V at. surface ratio ?1) has been investigated by temp. programmed redn. in hydrogen and by FT-Raman spectroscopy un ...
A dry sorption system for F removal from kiln flue gases using CaCO3 (limestone) produces flue gases with a residual F content of =21 days in the reactor. The flue gases are taken from the kiln firing process a ...
The chem. redn. of anthraquinone(I) has at least 2 disadvantages on the industrial scale; therefore, an electrochem. method was developed. The electrochem. redn. of I is done in a 2-compartment cell using concd. H2SO4 (15-17 mol/dm3) as the electrolyte at ...
Electrolysis cell with a bipolar electrode is described. The bipolar electrode in this electrolytic cell comprises a substrate coated with doped diamond electroconductive film. [on SciFinder (R)] ...

Abstract: A short overview of recent work on electroceramic materials relevant to methane-fueled SOFC systems is given. Various fuel feed options are considered, such as pure methane, biogas, and the addition of reforming agents. The principle and implemen ...
Secondary fly ash, resulting from thermal treatment processes, leads to a highly concd. chloride soln. with Cu, Pb, Cd and Zn as main heavy metals when dissolved in water. The selective electrodeposition of these heavy metals was studied. The goal was to r ...
oarse 8YSZ powders destined for plasma spray deposition were obtained from three different suppliers (Hochrhein, Magnesium Elektron, Unitec). Their ionic conductivities were measured by impedance spectroscopy on pellets prepared by vacuum hot pressing. Den ...
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 perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
