DSA type electrodes (IrOx/Ti) were prepd. by induction heating technique which allows a rapid decompn. of the precursor under anaerobic conditions. With this type of electrode, an activation process is obsd. in cyclic voltammetry which can be related to th ...
Cyclic voltammetry for the ferri-ferrocyanide redox couple was used to study the Ti/SnO2-Sb2O5 electrode prepd. by spray-pyrolysis under different conditions. Increasing the prepn. temp. and the duration of coating deposition results in a decrease of ip an ...
The morphol. examn. and the structural anal. of DSA-O2 electrodes [IrO2-Ta2O5 (70:30 mol%) coating] show that at moderate firing temp. (about 550 Deg), sepn. of phases occurs with the formation of agglomerates of IrO2 crystals and amorphous Ta2O5. At highe ...
The electrochem. behavior of some model org. compds. on boron-doped synthetic diamond thin film electrodes, obtained by HF-CVD on p-Si substrate was investigated. Only reactions involving simple electron transfer like hydroquinone/benzoquinone are active i ...
B-doped diamond films were deposited by large-area hot filament chem. vapor deposition (HFCVD) on Si and different industrial electrode materials, such as Ti, Zr, Nb, Ta, W, and graphite, with areas up to 50 * 60 cm2. B-doping levels ranging from 50 to sev ...
The objectives of this study were to validate new experimental techniques used to measure the log P of protonated drugs, and to investigate the inter- and intramolecular forces influencing the partitioning behavior of β-blockers in isotropic biphasic solve ...
The service life of SnO2-Sb2O5 coated anodes prepd. by the spray pyrolysis technique using Ti or Ti/IrO2 substrate, was studied under galvanostatic conditions (100 mA cm-2 in 1M H2SO4 at 25 Deg). The presence of an IrO2 interlayer between the Ti substrate ...
Oxygen and hydrogen peroxide electroredn. on La0.6Ca0.4CoO3 perovskite electrodes was studied in alk. media. Rotating disk electrodes were built using pure powders of the oxide to avoid any side reactions on the catalyst support, e.g. carbon. For O2 redn., ...
