Chemical and electrochemical promotion of supported rhodium catalyst

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 possible role of hydroxylation in the detoxification of atrazine in mature vetiver (Chrysopogon zizanioides nash) grown in hydroponics

Jean-Paul Schwitzguebel, Sylvie Vullioud-Marcacci

The resistance mechanism of vetiver (Chrysopogon zizanioides) to atrazine was investigated to evaluate its potential for phytoremediation of environment contaminated with the herbicide. Plants known to metabolise atrazinerely on hydroxylation mediated by b ...

Rational design of organo-ruthenium anticancer compounds

Ursula Röthlisberger, Ivano Tavernelli, Christian Gossens

Organometallic ruthenium(II)-arene complexes are currently attracting increasing interest as anticancer compds. with the potential to overcome drawbacks of traditional drugs like cisplatin with respect to resistance, selectivity, and toxicity. Rational des ...

Dynamic photoelectrochemistry at porphyrin-sensitised liquid/liquid interfaces

Nicolas Eugster

The interface between two immiscible electrolyte solutions provides a well-defined framework for fundamental studies of heterogeneous charge transfer processes. Recent developments in experimental methodology have allowed addressing the kinetics of electro ...

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 ...

Nonuniform radio-frequency plasma potential due to edge asymmetry in large-area radio-frequency reactors

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Juliette Ballutaud

In small area capacitive reactors, the rf and dc components of the plasma potential can be assumed to be uniform over all the plasma bulk because of the low plasma resistivity. In large area reactors, however, the rf plasma potential can vary over a long r ...

Methods and apparatus for patterning a surface

Jeffrey Alan Hubbell

The present invention provides methods and apparatus for locally patterning surfaces. In one such method, an oxidizable thioether is adsorbed onto a conductive surface 10. The surface is then contacted with a fluid medium M. A conducting stamp 12 is then b ...

Electrochemical investigation of ion implanted p-Si

The present work investigates the possibility of selective electrochemical metal deposition on ion implanted p-Si. The idea is that defects introduced into the substrate by ion implantation make it more susceptible to electrochemical reactions compared to ...
