Copper lattice tension boosts full-cell CO electrolysis to multi-carbon olefins and oxygenates

Electrocatalytic upgrading of CO to value-added multi-carbon (C2+) compounds is a promising approach to efficient carbon utilization. However, current full-cell systems have low energy conversion effi-ciencies under practical conditions due to the requirem ...

A mixture model to take into account diluted gas in liquid flow: applications to aluminium electrolysis

Emile Tryphon Pierre Soutter

Aluminium is a metal sought in the industry because of its various physical properties. It is produced by an electrolysis reduction process in large cells. In these cells, a large electric current goes through the electrolytic bath and the liquid aluminium ...

Flow pattern observations and flow pattern map for adiabatic two-phase flow of carbon dioxide in vertical upward and downward direction

Jürg Alexander Schiffmann, Rémi Revellin, David Schmid

A test facility to investigate flow pattern transitions of vertical two-phase flow of CO2 has been built within the scope of the high-luminosity detector upgrades at the European Organization for Nuclear Research (CERN). Adiabatic flow pattern observations ...

Grafting of Alkali Metals on Fumed Silica for the Catalytic Dehydrogenation of Methanol to Formaldehyde

Oliver Kröcher, Alimohammad Bahmanpour, Christophe Jean Baranowski

Water free, non-oxidative catalytic dehydrogenation of methanol to formaldehyde is an important process for the formation of anhydrous, molecular formaldehyde (FA). Sodium or sodium-containing salts were shown to catalyze the reaction, but their reaction m ...

Doping of epitaxial graphene by direct incorporation of nickel adatoms

Gianluca Prandini, Virginia Carnevali

Direct incorporation of Ni adatoms during graphene growth on Ni( 111) is evidenced by scanning tunneling microscopy. The structure and energetics of the observed defects is thoroughly characterized at the atomic level on the basis of density functional the ...

Guest dynamics in methane hydrates and hydrogen hydrates under high pressure

Umbertoluca Ranieri

Hydrates of gas are non-stoichiometric inclusion compounds constituted of water and gas. Therein, the water molecules are hydrogen-bonded and form three-dimensional crystalline networks incorporating different kinds of polar or nonpolar guest gas molecules ...

Full-scale evaluation of methane production under oxic conditions in a mesotrophic lake

Sabine Flury McGinnis

Oxic lake surface waters are frequently oversaturated with methane (CH4). The contribution to the global CH4 cycle is significant, thus leading to an increasing number of studies and stimulating debates. Here we show, using a mass balance, on a temperate, ...

Architectural design scenarios with building-integrated photovoltaic solutions in renovation processes: Case study in Neuchâtel (Switzerland)

Emmanuel Rey, Sophie Lufkin, Sergi Aguacil Moreno

In view of the importance of urban renewal processes, building-integrated photovoltaic (BIPV) systems can potentially provide a crucial response to the energy turnaround challenges. Functioning both as envelope material and electricity generator, they can ...

Chemical Equilibria in Formic Acid/Amine-CO2 Cycles under Isochoric Conditions using a Ruthenium(II) 1,2-Bis(diphenylphosphino)ethane Catalyst

Gabor Laurenczy, Katerina Stefania Sordakis

The equilibrium position in formic acid/amine–CO2 systems has been examined as a function of pressure and tem- perature under isochoric conditions. The homogeneous ruthe- nium(II)-1,2-bis(diphenylphosphino)ethane catalyst was active in both reactions, that ...
