Registration of long-range surface plasmon resonance by angle-scanning feedback and its implementation for optical hydrogen sensing

An optical technique devised for the detection of the ultrasharp angular resonance of long-range surface plasmons (LRSPs) is described. The LRSPs propagate along an 8 nm-thick palladium (Pd) film deposited on a one- dimensional photonic crystal structure a ...

Hydrogen production from formic acid

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25 DEG C). ...

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

Homogeneous catalytic decomposition of formic acid for high pressure hydrogen generation

Céline Fellay

The main obstacles in the widespread use of hydrogen as energetic alternative to fossil fuels are storage problems intrinsically linked to its extremely light and explosive nature. Since no ideal storage systems currently exist, reversible fixation of hydr ...

Comment on « Angular distributions of H-induced HD and D2 desorptions from the Si(100) surfaces » [J. Chem. Phys. 124, 054715 (2006)]

Régis Bisson

In their article, Inanaga et al. have presented an angular distribution for the desorption of hydrogen molecules induced by hydrogen atoms impinging on a hydrogenated Si(100) surface and compared the measurement with classical trajectory calculations based ...

Hydrogen Sensors based on Nanoscaled Discontinuities in Palladium

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena, Thomas Kiefer, Arnaud Salette

In this project we develop hydrogen sensors based on nanoscaled discontinuities (nanogaps) in palladium (Pb). These nanogaps reversibly close and open upon hydrogen/air cycling due to an increased lattice constant in the hydrated state. Therewith, an elect ...

Non-thermal plasma catalytic reactor for hydrogen production by direct decomposition of H2S

Albert Renken, Lioubov Kiwi

Hydrogen production by non-thermal plasma (NTP) assisted direct decomposition of hydrogen sulfide was carried out in a novel dielectric barrier discharge (DBD) reactor with the inner electrode made of sintered metal fibers (SMF) also functioning as catalys ...

Pulse plating of Ni-W alloys from model electrolytes

Dieter Landolt

Pulse plating of nickel-tungsten alloys has been studied from two citrate ammonia based model electrolytes containing either an excess of nickel or an excess of tungsten. The alloy composition and current efficiency were determined for pulse periods rangin ...

The impact of Co and Ni speciation on methanogenesis in sulfidic media - Biouptake versus metal dissolution

Graciela Gonzalez Gil

The speciation of the trace nutrients Co(II) and Ni(II) in sulfide containing media can control the methanogenic activity of Methanosarcina sp., which is of importance for the optimisation of anaerobic treatment of wastewater containing methanol. To obtain ...
