A quasi-Delphi study on technological barriers to the uptake of hydrogen as a fuel for transport applications : production, storage and fuel cell drivetrain considerations

The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community c ...

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 ...

Dissociation of Water on Anatase TiO2 Nanoparticles: the Role of Undercoordinated Ti Atoms at Edges

Michel Posternak, Alfonso Baldereschi

We show with DFT calculations that hydroxyl formation on anatase TiO2 from dissociation of water molecules is strongly enhanced by a nanostructured state of the oxide, involving the occurrence of complexes consisting of undercoordinated 4-fold Ti-2-fold O ...

Desulfinylation of Prop-2-enesulfinic Acid: Experimental Results and Mechanistic Theoretical Analysis

Pierre Vogel, Dean Markovic

The potential energy surfaces of the desulfinylation of prop-2-enesulfinic acid (13) in CH2Cl2 solution at -15 degrees C have been explored by quantum calculations and analyzed with kinetic data obtained for the reaction in absence or presence of additives ...

Release kinetics of volatiles from smectite clay minerals

Pascal Clausen

The focus of this thesis was on the mechanisms of release of volatile molecules from smectite clay minerals. The weight loss was monitored by thermogravimetry, differential calorimetry, and mass spectrometry under isothermal conditions and under ramp tempe ...

A combined QM/MM and Classical Molecular Dynamics Study of [Ru(bpy)3]2+ in Water

Ursula Röthlisberger, Ivano Tavernelli, Marc-Etienne Moret

The solvation of the Ru(bPy)(3) (bpy = 2,2'-bipyridyl) cation was studied by molecular dynamics simulations, using both a hybrid QM/MM Car-Parrinello scheme and a classical force field. The trajectory analysis reveals that the first solvation sphere ...

Water adsorption on a sodium smectite clay surface: an ab initio study

John Christopher Plummer, Pascal Clausen

Using calculations based on density-functional theory, we explore the configurations that water molecules (2,3,4;6) assume on the surface a sodium 2:1 smectite clay with isomorphic substitutions both on octahedral and tetrahedral sheets. The hydrophilicity ...

Studies of blob formation, propagation and transport mechanisms in basic experimental plasmas (TORPEX and CSDX)

Ambrogio Fasoli, Ivo Furno, Benoît Labit, Christian Gabriel Theiler, Stefan Müller

The findings of previous blob studies in the interchange-dominated regime of TORPEX helium (Müller et al 2007 Phys. Plasmas 14 110704) and hydrogen plasmas (Furno et al 2008 Phys. Rev. Lett. 100 055004) are summarized and compared. The onset of blobs is s ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Microfabricated solid oxide fuel cells

Samuel Rey-Mermet

Micro-fabricated solid oxide fuel cells (µSOFCs) are finding an increasing interest as potential power sources for portable devices such as MP3 players or laptops. The aim of this work was to fabricate a µSOFC demonstrator that works at 500°C and is fuelle ...
