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

Acetate production from lactose by Clostridium thermolacticum and hydrogen-scavenging microorganisms in continuous culture - Effect of hydrogen partial pressure

Jean-Paul Schwitzguebel, Christophe Collet

The effect of the addition of hydrogen-consuming microorganisms on the metabolism of Clostridium thermolacticum was studied. By growing this bacterium in continuous culture at 58 degrees C, on 29 mmol lactose l(-1) (10 g l(-1)) in the feed, with the H-2-co ...

Ammonia as a fuel in solid oxide fuel cells

Jan Van Herle

The use of ammonia as a source of hydrogen for fuel cells has received little attention until now. Ammonia offers several advantages over hydrogen as a fuel and is produced commercially in massive quantities and as a biogas. This paper describes the result ...

Determination of hydrogen concentration in ionic liquids and the effect (or lack of) on rates of hydrogenation

Paul Joseph Dyson, Gabor Laurenczy

The solubility of hydrogen and the corresponding Henry coefficients for 11 ionic liquids have been determined in situ at 100 atm H-2 pressure and are much lower than expected; attempts to correlate the solubility of hydrogen in the ionic liquids with the r ...

Structural dynamics in quantum solids. II. Real-time probing of the electronic bubble formation in solid hydrogens

Majed Chergui, Franco Vigliotti, Luigi Bonacina

The ultrafast dynamics of electronic bubble formation upon excitation of the A(3ss) Rydberg state of NO trapped in solid H2 and D2 was studied by femtosecond pump-probe spectroscopy. The evolution of the spherical bubble is followed in real time by a probe ...

Ultrafast Structural dynamics in solid hydrogens: A model for condensed phase quantum systems

Majed Chergui, Franco Vigliotti, Luigi Bonacina

Structural dynamics in solid hydrogens is impulsively triggered by femtosecond excitation of the lowest Rydberg state of the NO impurity. The resulting charge redistribution induces a local radial deformation of the medium ("bubble" formation) around the ...

Structural dynamics in quantum solids. I. Steady-state spectroscopy of the electronic bubble in solid hydrogens

Majed Chergui, Franco Vigliotti

The structural changes due to formation of electronic bubbles in solid D2 are studied by fluorescence, fluorescence-excitation, and fluorescence-depletion spectroscopy of the lowest Rydberg state, A 2S+(3ss), of the NO impurity. The A X band is strongly bl ...

Alternative anode materials for methane oxidation in solid oxide fuel cells

Joseph Sfeir

Fuel Cells are electrochemical devices that are able to directly convert chemical energy to electrical energy, without any Carnot limitation. Hence, their energy efficiencies are relatively high. Among the various types of fuel cells, solid oxide fuel cell ...

Dynamics of electronic "bubble" formation in solid hydrogen

Majed Chergui, Franco Vigliotti, Marcia Portella Oberli

Excitation of the A(3ss) Rydberg state of NO trapped in an H2 crystal leads to the electronic bubble formation around the NO impurity, resulting in an increase of 0.9 .ANG. of the ground state cage radius. Its dynamics was followed in real-time by femtosec ...

Dynamics of Electronic "Bubble" Formation in Solid Hydrogen: A Classical Model Calculation based on Fluid Dynamics

Majed Chergui, Franco Vigliotti

A model based on fluid dynamics is proposed, which describes the dynamics of a photoinduced spherical deformation in solid hydrogen. The dynamics is driven by femtosecond excitation of the lowest A(3ss) Rydberg state of NO trapped in an H2 crystal, leading ...
