Bubble evolution on a vertical electrode under extreme current densities

Christos Comninellis, Hannes Bleuler, Rolf Wüthrich

Under gas evolution, the current voltage characteristics of an electrochemical cell are strongly affected by the presence of growing bubbles. At high current densities, the evolution of the bubbles becomes the rate limiting step of the electrochemical proc ...

Redox Properties of Self-Assembled Gold Nanoclusters

Hubert Girault, Bin Su

The redox properties of a monolayer of alkanethiolate-protected gold nanoclusters (MPCs) constructed on a gold slide electrode was studied in 1,2-dichloroethane (DCE) electrolyte solutions. The influence of the electrostatic interaction between attached MP ...

Electrochemical incineration of chloranilic acid using Ti/IrO2, Pb/PbO2 and Si/BDD electrodes

Christos Comninellis

The electrochem. oxidn. of chloranilic acid (CAA) was studied in acidic media at Pb/PbO2, B-doped diamond (Si/BDD) and Ti/IrO2 electrodes by bulk electrolysis expts. under galvanostatic control. The obtained results have clearly shown that the electrode ma ...

Development of an electroless post-processing technique for depositing gold as electrode material on CMOS devices

Nico de Rooij, Peter Van der Wal

The limited electrode density and thus, the limited spatial resolution of substrate-integrated microelectrodes arrays (MEAs) used in in-vitro electrophysiology are currently considered as the main constraints of this technique. By taking advantage of the c ...

Relation between potential and catalytic activity of rhodium in propylene combustion

Christos Comninellis, György Foti, Ivan Bolzonella

The relation between the catalyst potential and the catalytic performance has been investigated in the gas-phase combustion of propylene with oxygen over rhodium catalysts at 375 DegC. The rhodium catalyst, deposited on yttria-stabilized zirconia (YSZ) sol ...

Promotion électrochimique des catalyseurs à base de rhodium et d'iridium

Justyna Eaves

In this thesis, the electrochemical promotion of lr and Rh based catalysts was studied for the complete combustion of ethylene and propylene. The study was performed by using two types of electrocatalytical cells: a classical, pellet type cell and a tubula ...

Effects of electrical leakage currents on MEMS reliability and performance

Herbert Shea, Shan Jin

Electrostatically driven MEMS devices commonly operate with electric fields as high at 108 V/m applied across the dielectric between electrodes. Even with the best mechanical design, the electrical design of these devices has a large impact both on perform ...
