The aim of this work was to develop a microchamber system for performing electrophysiological measurements on epithelial surface on culture membranes in the mm2 range. This miniaturised system permits the use of small quantities of epithelial cells, which ...
A wide range of applications in neurotechnological research rely on planar microelectrode arrays (MEA) but the disadvantage of these systems is the low density of electrodes caused by the problem of wiring a great number of electrodes. In turn this results ...
This paper addresses the problem of time-dependent dielectric breakdown of Pb(Zr,Ti)O-3 (PZT) thin films. It is shown by using constant-current breakdown measurements, that for PZT film capacitors with Pt and SrRuO3 (SRO) electrodes the breakdown onset is ...
A newly designed thin-layer STM (TLSTM) technique is presented based on a microfabricated probe combining an electrolytic STM probe with an annular iridium oxide microelectrode operating as a potential-controlled generator or scavenger of H+. This TLSTM co ...
Polycrystalline aluminum nitride thin films were deposited onto platinum, aluminum, and titanium electrodes by reactive magnetron sputtering in the pulsed direct current mode. The films exhibited all a columnar microstructure and a c-axis texture. The buil ...
The Boron-Doped Diamond (BDD) electrode is a new electrode material with high stability, even at high anodic potential. Furthermore BDD is not prone to fouling. Due to these properties, BDD can provide new opportunities in electrochem. synthesis of org. an ...
The electrocombustion technique has recently been proposed to oxidize nonbiodegradable org. pollutants such as chlorophenol. The authors considered two different types of electrode material: boron doped diamond (BDD) and lead dioxide electrodeposited on Ti ...
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 ...

On-chip cell handling and analysis is given more and more interest, as new cytometry devices can be realised or efficiently combined and integrated. The developed sensor presents several improvements compared to other integrated flow cytometers. It is aime ...
The mechanism of the oxygen redn. reaction (orr) was studied in alk. media at La0.6Ca0.4CoO3-activated carbon electrodes in a channel flow cell (CFC). The electrodes were made by depositing a mixt. of the perovskite (La0.6Ca0.4CoO3) powder as the catalyst, ...
