Electrochemical and photoelectrochemical investigation of new carboxylatobipyridine(bis-bipyridine)ruthenium(II) complexes for dye-sensitized TiO2 electrodes

Ulf Anders Hagfeldt

Methods for the prepn. and purifn. of new carboxylated 2,2'-bipyridine ligands, two of which contain the new anchoring functionality malonate, and a reliable method for the synthesis of the corresponding Ru(bpy)2(L)2 complexes are described. Their s ...

Electrochemical promotion of ruthenium oxide catalysts for the gas phase combustion of ethylene

Christos Comninellis

In this paper the electrochem. promotion of RuO2 catalyst was studied for the oxidn. of C2H4 to CO2 and H2O. The reaction rate can be increased of up to a factor of 115 by anodic polarization. A kinetic model for the simulation of the open circuit reaction ...

Conducting barriers for direct contact of PZT thin films on reactive substrates

Nava Setter, Paul Muralt, Thomas Maeder

Several bottom electrode systems for ferroelectric thin film deposition onto reactive substrates or reactive metal films have been investigated with respect to chemical barrier properties and contact resistivity. Such electrode systems should not deteriora ...

Grain boundary segregation under neutron irradiation in dilute alloys

Irradiation-induced segregation mechanisms are classified into solute-point-defect complex type and inverse Kirkendall type. For solutes that have a strong interaction with interstitials in a dilute alloy, the complex effect plays an important part in the ...

Electrochemical promotion of ruthenium oxide catalysts for the gas phase combustion of ethylene

Christos Comninellis

The electrochem. promotion of RuO2 catalyst films, deposed onto yttria stabilized zirconia solid electrolyte (YSZ), was studied for the gas phase combustion of ethylene. Two order of magnitude increase in the reaction rate was obtained during anodic polari ...

Conducting barrier electrodes for direct contact of PZT thin films on tungsten

Nava Setter, Paul Muralt, Thomas Maeder

Two W protection schemes for direct-contact bottom electrodes for PZT thin films, namely RuO2/Cr and RuO2/Ru, were compared with respect to protective performance and contact resistance up to 800 degrees C annealing temperature in oxygen. Cr clearly offers ...
