The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...
The electrochem. oxidn. of EDTA was studied at boron-doped diamond (BDD) electrodes. Cyclic voltammetry in the potential region of water stability showed that EDTA is oxidized in an irreversible 2-electron-transfer mechanism. No fouling phenomena were noti ...
Organic light emitting devices (OLED) are among the most promising future technologies for the manufacture of flat and inexpensive displays. Although OLEDs provide already much higher brightness as compared to liquid crystals devices (LCD), they have a maj ...
We propose a model to determine the influence of different cell properties, such as size, membrane capacitance and cytoplasm conductivity, on the impedance spectrum as measured in a microfabricated cytometer. A dielectric sphere of equivalent complex permi ...
Copper wires each one containing a pseudo-spin valve of Co/Cu/Co were produced by electrodeposition inside nanoporous polycarbonate membranes. These wires have a diameter of 40 nm and a length of 6000 nm of which only 50 nm relates to the spin valve. In or ...
In their article, ‘‘AC frequency characteristics of coplanar impedance sensors as design parameters’’, Hong et al.1 present an analytical model for the calculation of the resistance between two electrodes in a microchannel. However, their measurements fit ...
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 ...
The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective oxidn. occurs ...
The electro-combustion of water sol. polymeric contaminants such as polyacrylates (PA) in aq. acid soln. using a B-doped diamond anode was studied by bulk electrolysis in 1 mol/dm3 HClO4 under galvanostatic conditions in a wide range of PA concns. and curr ...
Electrode effects are known for more than 150 years. These effects, with undesirable consequences in industrial aluminium electrolysis, can be used to micro-machine glass with Spark Assisted Chemical Engraving (SACE). In this paper, a novel approach for th ...
