Micromechanical Properties of Periodic Nanoporous Alumina

The structure of anodized nanoporous alumina is described as a closely-packed hexagonal arrangement of monodispersed nanopores, of which size and interval can be controlled by changing the anodization conditions. Nanoporous alumina thin films with highly o ...

Analysis of thin film cracking and buckling on compliant substrate by fragmentation test

Yves Leterrier

Application of coating fragmentation test for determination of coating properties is considered. A probabilistic model of coating fragmentation under uniaxial tensile loading is applied for coating and interface property identification of thin brittle coat ...

Electrochemical incineration of chloromethylphyenoxy herbicides in acid medium by anodic oxidation with boron-doped diamond electrodes

Christos Comninellis, Béatrice Marselli Fuerer, Pierre-Alain Michaud

The electrochemical degradation of saturated solutions of herbicides 4-chloro-2-methylphenoxyacetic acid, 2-(4-chlorophenoxy)-2-methylpropionic acid and 2-(4-chloro-2-methylphenoxy)propionic acid in 1 M HClO4 on a boron-doped diamond (BDD) thin film anode ...

Heterogeneous oligonucleotide-hybridization assay based on hot electron-induced eletrochemiluminescence of a rhodamine label at oxide-coated aluminium and silicon electrodes

Nico de Rooij

This paper describes a heterogeneous oligonucleotide-hybridization assay based on hot electron-induced electrochemiluminescence (HECL) of a rhodamine label. Thin oxide-film coated aluminum and silicon electrodes were modified with an aminosilane layer and ...

Electrochemical synthesis and magnetic properties of CoFe2O4 nanowire arrays

Jean-Philippe Ansermet

We report the preparation and magnetic properties of Co2FeO4nanowires grown by electrodeposition inside the pores of anodic aluminum oxide (AAO). The synthesis requires two successive steps: the electrodeposition of fairly amorphous Fe-Co oxides or hydroxi ...

Anisotropic nanoporous coating

Heinrich Hofmann, Laurent-Dominique Piveteau

Porous coating production, e.g. for medical implant, involves depositing first mono-layer(s) of temporary particles on surface, depositing coating(s) on particles, eliminating temporary particles forming pores, and coating fixation step NOVELTY - Producing ...

Simulation of SOFC stack and repeat elements including interconnect degradation and anode reoxidation risk

Daniel Favrat, Jan Van Herle, Diego Larrain

Reliability of SOFC stacks is a complex and key issue. This paper presents a simulation study including some degradation processes, namely, interconnect degradation and the anode reoxidation potential. Quantification for these phenomena has been included i ...

Electrochemical promotion of ethylene oxidation over Rh catalyst thin films sputtered on YSZ and TiO2/YSZ supports

Christos Comninellis, György Foti

The effect of electrochem. promotion of catalysis or nonfaradaic electrochem. modification of catalytic activity or electropromotion was studied for the model reaction of ethylene oxidn. on sputter-coated Rh films. The thin (40 nm) Rh films were deposited ...

Chemical and electrochemical promotion of supported rhodium catalyst

Olena Baranova

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 ...

Partial release and detachment of microfabricated metal and polymer structures by anodic metal dissolution

Philippe Renaud, Arnaud Bertsch, Stefan Metz

The large majority of microelectromechanical systems (MEMS) are fabricated on silicon, glass or Pyrex substrates by manufacturing techniques, which originated from the semiconductors industry. However, their final application often requires removal of the ...
