Hydrogen storage in the carbon dioxide/formic acid system, using homogeneous iron(II)-phosphine catalysts in aqueous solution
The valorization of carbon dioxide and its transformation into useful chemicals is essential as mankind consumes more and more fossil fuels, thus producing equivalent wastes. The storage of hydrogen, a promising energy carrier, is also of great interest in ...
EPFL2018Additive free, room temperature direct homogeneous catalytic carbon dioxide hydrogenation in aqueous solution using an iron(II) phosphine catalyst
Gabor Laurenczy, Mickael Montandon-Clerc
The negative consequences of the global warming require an important reduction of CO2 emission; and the valorization of the carbon dioxide, its transformation into useful chemicals is essential. We present here our studies on the direct CO2 hydrogenation r ...
2018Impact of CO2 injection on the hydro-mechanical behaviour of a clay-rich caprock
Lyesse Laloui, Valentina Favero
The safe storage of CO2 in deep reservoir units requires an efficient sealing of the overlaying caprock. The acidic environment caused by the dissolution of CO2 into the pore fluid can induce changes in the microstructure of the material over the long term ...
2018Efficiency improvement of an all-vanadium redox flow battery by harvesting low-grade heat
Hubert Girault, Alberto Battistel, Christopher Raymond Dennison, Danick Reynard
Redox flow batteries (RFBs) are rugged systems, which can withstand several thousand cycles and last many years. However, they suffer from low energy density, low power density, and low efficiency. Integrating a Thermally Regenerative Electrochemical Cycle ...
2018Chemical shifts in molecular solids by machine learning
David Lyndon Emsley, Michele Ceriotti, Albert Hofstetter, Félix Benedito Clément Musil, Sandip De, Federico Maria Paruzzo
Due to their strong dependence on local atonic environments, NMR chemical shifts are among the most powerful tools for strucutre elucidation of powdered solids or amorphous materials. Unfortunately, using them for structure determination depends on the abi ...
2018Elevated Concentrations of 4-Bromobiphenyl and 1,3,5-Tribromobenzene Found in Deep Water of Lake Geneva Based on GCxGC-ENCI-TOFMS and GCxGC-mu ECD
Jeremy Samuel Arey, Saer Samanipour, Petros Dimitriou Christidis, Deedar Nabi
We quantified the concentrations of two little-studied brominated pollutants, 1,3,5-tribromobenzene (TBB) and 4-bromobiphenyl (4BBP), in the deep water column and sediments of Lake Geneva. We found aqueous concentrations of 625 +/- 68 pg L-1 for TBB and 66 ...
Amer Chemical Soc2017Passive sampling for monitoring organic contaminants in aquatic systems
Dominique Grandjean, Sylvain Coudret, Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer
Passive sampling has been shown to be a good alternative to grab sampling. Because of the in-situ accumulation in samplers, limits of quantitation are low enough to measure organic pollutants in water. In addition, integrative passive samplers enable to se ...
2017Positional Variance in NMR Crystallography
David Lyndon Emsley, Albert Hofstetter
We propose a method to quantify positional uncertainties in crystal structures determined by chemical-shift-based NMR crystallography. The method combines molecular dynamics simulations and density functional theory calculations with experimental and compu ...
American Chemical Society2017Solid oxide fuel cell anode degradation by the effect of hydrogen chloride in stack and single cell environments
Jan Van Herle, Christian Ludwig, Stefan Diethelm, Hossein Madi, Davide Papurello
The poisoning effect by hydrogen chloride (HCl) on state-of-the-art Ni anode-supported solid oxide fuel cells (SOFCs) at 750 degrees C is evaluated in either hydrogen or syngas fuel. Experiments are performed on single cells and short stacks and HCl concen ...
2016Hyperpolarized 6Li as a probe for hemoglobin oxygenation level
Rolf Gruetter, Mor-Miri Mishkovsky, Arnaud Comment, Ruud van Heeswijk, Riccardo Balzan
Hyperpolarization by dissolution dynamic nuclear polarization (DNP) is a versatile technique to dramatically enhance the nuclear magnetic resonance (NMR) signal intensity of insensitive long-T1 nuclear spins such as 6 Li. The 6 Li longitudinal relaxation o ...
