Excimer laser crystallization of amorphous silicon on metallic substrate

An attempt has been made to achieve the crystallization of silicon thin film on metallic foils by long pulse duration excimer laser processing. Amorphous silicon thin films (100 nm) were deposited by radiofrequency magnetron sputtering on a commercial meta ...

Synthesis and Characterization of High-Photoactivity Electrodeposited Cu2O solar absorber by photoelectrochemistry and ultrafast spectroscopy

Michael Graetzel, Jacques-Edouard Moser, Adriana Paracchino, Jan Cornelius Brauer

2012

Iridium dioxide electrodes form part of the dimensionally stable anodes (DSA®) and this electrode material is widely used in many industrial processes namely water electrolysis, metal electro-winning, cathodic protection and electro-organic synthesis due t ...

Rapid chromium quantification in solid oxide fuel cell cathodes

Jan Van Herle, Josef Andreas Schuler, Pietro Tanasini

The detection and quantification of small quantities of Cr in (La,Sr)MnO3/Y–ZrO2 solid oxide fuel cell (SOFC) cathodes by energy-dispersive X-ray spectroscopy (EDXS) is not straightforward as Cr X-ray emission lines overlap with La/Mn and O lines. This wor ...

Direct and mediated electrochemical oxidation of ammonia on boron-doped diamond electrode

Christos Comninellis, Agnieszka Kapalka

Direct (non-mediated) electrochemical oxidation of ammonia on boron-doped diamond (BDD) electrode proceeds mainly at high pH (>8) via free ammonia (NH3) oxidation. To enhance ammonia oxidation on BDD at low pH (

Nickel-Zirconia Anode Degradation and Triple Phase Boundary Quantification from Microstructural Analysis

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes

Microstructural evolution of anode supported solid oxide fuel cells (SOFC) during medium-term stack testing has been characterized by scanning electron microscopy (SEM). Low acceleration voltage SEM imaging is used to separate the three anode phases (nicke ...

On-line Electrogeneration of Copper-Peptide Complexes in Microspray Mass Spectrometry

Hubert Girault, Michel Prudent

The interaction of copper ions with peptides was investigated by electrospray mass spectrometry. Two electrospray micro-emitters were compared, the first one with a platinum electrode using a copper(II) electrolyte solution containing a peptide sample, and ...

Methods for functionalization of microsized polystyrene beads with titania nanoparticles for cathodic electrophoretic deposition

Stefano Mischler, Johann Michler

Functionalization of colloidal particles based on the use of polyelectrolytes and heterocoagulation was combined with electrophoretic deposition (EPD), with the aim of depositing titania-polystyrene (TiO2-PS) composite particles on Ti6A14V substrates. The ...
