Effect of electrode potential on the tribocorrosion of tungsten

Michel Declercq, Didier Bouvet, Stefano Mischler, Jelena Stojadinovic

The tribocorrosion behavior of tungsten sliding against an alumina ball was evaluated in sulfuric acid under applied electrode potential. Surface chemistry of worn and unworn surfaces was evaluated using XPS and AES. Quasi-potentiostatic polarization curve ...

Combining diamond electrodes with GaN heterostructures for harsh environment ISFETs

Nicolas Grandjean, Jean-François Carlin

Electrochemistry and biochemistry have always been ideal applications for diamond due to its chemical inertness and stability, sensitivity and biocompatibility. Several diamond ChemFET concepts have been proposed to date, however further improvements are s ...

Functional Electrospray Emitters

Hubert Girault, Michel Prudent

Electrospray ionisation (ESI) is a soft technique used in mass spectrometry (MS) analysis able to introduce a wide variety of analytes in the gas phase. Briefly, it consists in the application of a high- voltage to a solution to spray it through a small or ...

Electrodeposition and Characterization of Bismuth Telluride Nanowires

Simon Granville

In this work, we report thermoelectric measurements on electroplated bismuth telluride nanowires. Porous polycarbonate membranes, obtained by ion-track irradiation lithography, were chosen as electroplating templates. Bismuth telluride nanowires were achie ...

High Molar Extinction Coefficient Ruthenium Sensitizers for Thin Film Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Jun Ho Yum

We present two sensitizers, Ru(4,4'-dicarboxyvinyl)-2,2'-bipyridine)(4,4'-dinonyl-2,2'-bipyridine)(NCS)(2) (K9) and Ru(4,4'-dicarboxy(phenylethenyl)-2,2'-bipyridine)(4,4'-dinonyl-2,2'-bipyridine)(NCS)(2) (K23), which were synthesized and characterized by a ...

Fabrication of metallic nanoparticles by electrochemical discharges

Hannes Bleuler, Ashwin Lal

A method for the fabrication of metallic nanoparticles in large quantities by electrochemical discharges is presented. In an aqueous electrolyte, large current density (similar to 1 A/mm(2) at similar to 20 V) leads to the formation of a 'gas film' around ...

Electrochemical aspects of display technology based on nanostructured titanium dioxide with attached viologen chromophores

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt

Progress in recent years in the field of electrochromic displays based on viologen modified high-surface area TiO2 electrodes (Vio2+/TiO2) has moved the technol. towards commercialization. Viologen mols. (Vio2+), derivatized with phosphonic acid attachment ...

Conductive supports for combined AFM–SECM on biological membranes

Nico de Rooij, Terunobu Akiyama

Four different conductive supports are analysed regarding their suitability for combined atomic force and scanning electrochemical microscopy (AFM-SECM) on biological membranes. Highly oriented pyrolytic graphite (HOPG), MoS 2, template stripped gold, and ...

Second harmonic generation response by gold nanoparticles at the polarized water/2-octanone interface: from dispersed to aggregated particles

Hubert Girault, Pierre-François Marie Brevet

Gold nanoparticles with a diameter of approximately 20 nm have been observed at the polarized water/2-octanone interface by the nonlinear optical technique of second harmonic generation. Electric field induced adsorption of the gold particles at this liqui ...

Electrochemiluminescent hybridization chip with electric field mismatch discrimination

Nico de Rooij

This paper describes a heterogeneous DNA-hybridization assay based on electrochemiluminescence (ECL) detection on gold electrodes. Short, 15-mer oligonucleotides were conjugated with a synthesized electrochemiluminescent label, bis(2,2′-bipyridine)-5-isoth ...
