Thermally-activated flow in nominally binary Al-Mg alloys

William Curtin

The temperature-dependent flow behavior in nominally binary Al-Mg alloys measured recently (Jobba etal., 2015; Niewczas et al., 2015) is interpreted in the context of a parameter-free solute strengthening model. The recent measurements show consistently hi ...

The Role of Bromide in Oxidative Water Treatment

Michèle Bernadette Heeb

Bromide (Br-) levels in fresh waters range from a few ¿gL-1 to several mgL-1. In seawater its concentration is about 67 mgL-1. The goal of this thesis is to assess the fate of bromide during oxidative water treatment and to explore its influence on these t ...

Electrochemical Reduction of CO2 Catalyzed by Metal Oxides

Yeonji Oh

A rapidly growing population and industrialization have caused the exploitation of natural resources in keeping with fossil fuels shortage. Due to the combustion of fossil fuels, the concentration of CO2 in the earth's atmosphere, which is a potent greenho ...

A Simple Liquid-Liquid Biphasic System for Hydrogen Peroxide Generation

Hubert Girault, Gunther Wittstock

Although electron transfer reactions at liquid liquid interfaces have been thoroughly studied in the presence of deliberately added potential determining ions or phase transfer catalysts, little is known about these reactions in the absence of the above sp ...

Description of the capacity degradation mechanism in LaNi5-based alloy electrodes

Andreas Züttel, Philippe Mauron, Mariana Spodaryk, Marco Roman Holzer

The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...

Study of the Redox Properties of Singlet and Triplet Tris(2,2 '-bipyridine)ruthenium(II) ([Ru(bpy)(3)](2+)) in Aqueous Solution by Full Quantum and Mixed Quantum/Classical Molecular Dynamics Simulations

Ursula Röthlisberger, Ivano Tavernelli, Polydefkis Diamantis, Jérôme Florian Gonthier

The oxidation of ground-state (singlet) and triplet Ru(bpy)(3) were studied by full quantum-mechanical (QM) and mixed quantum/classical (QM/MM) molecular dynamics simulations. Both approaches provide reliable results for the redox potentials of the t ...

Heat transfer modeling in integrated photoelectrochemical hydrogen generators using concentrated irradiation

Sophia Haussener, Saurabh Yuvraj Tembhurne, Mikaël Dumortier

The direct conversion of solar energy and water into a storable fuel via integrated photoelectrochemical (PEC) devices is investigated. Particularly, the proposed device uses concentrated solar irradiation in order to minimize the amount of rare and expens ...

Tribocorrosion of Pulsed Plasma-Nitrided CoCrMo Implant Alloy

Stefano Mischler

In the present study, a forged CoCrMo (ISO 5832-12) has been subjected to pulsed plasma treatment in a N-2/H-2 atmosphere at low temperatures (below 500 A degrees C). This treatment resulted in the formation of a layer composed by dispersed chromium nitrid ...
