The Effect of Free-Atmosphere Stratification on Boundary-Layer Flow and Power Output from Very Large Wind Farms

Fernando Porté Agel, Mahdi Abkar

Large-eddy simulation is used to study the influence of free-atmosphere stratification on the structure of atmospheric boundary-layer flow inside and above very large wind farms, as well as the power extracted by the wind turbines. In the simulations, tuni ...

Luminescence studies on photostimulable phosphor CsBr:Eu2+

Giovanni Dietler, Serguei Sekatski, Kanat Dukenbayev

Photostimulable phosphor CsBr:Eu2+ is prepared through a solid-state reaction. The effect of annealing atmosphere on photoluminescence and photostimulated luminescence was investigated. Optimum luminescence intensity was obtained when samples were prepared ...

Ruthenium-catalyzed Atom Transfer Radical Addition Reactions

Kay Severin

Certain ruthenium complexes are potent catalysts for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions, in particular if they are used in conjunction with reducing agents such as magnesium. This short overview summarizes recent develop ...

Hydrogen evolution at polarised liquid/liquid interfaces catalyzed by molybdenum disulfide

Hubert Girault, Xile Hu, Heron Vrubel, Peiyu Ge, Imren Hatay

Molybdenum disulfide microparticles in suspension in an aqueous acidic solution adsorb at the interface with an organic electrolyte solution containing the reducing agent, decamethylferrocene, to catalyse hydrogen evolution. This catalytic process has been ...

Sequential ATRA-Reductive Cyclopropanation Reactions with a Ruthenium Catalyst in the Presence of Manganese

Kay Severin, Charlotte Buron

Atom-transfer radical addition (ATRA) reactions of ethyl trichloroacetate, dichloromalononitrile, or diethyl 2,2-dichloromalonate with olefins followed by dechlorination have provided functionalized cyclopropanes in one step. The RuIII complex [Cp*RuCl2(PP ...

The electro-deoxidation of dense titanium dioxide precursors in molten calcium chloride giving a new reaction pathway

Duncan Thomas Lindsay Alexander

A new study is presented on the electro-deoxidation of porous TiO2 precursors in molten calcium chlo- ride electrolytes. It is shown that by reducing precursor open porosity from standard values of ≥25% to ∼11–12%, such that there is insufficient free volu ...

Detection of hydrogen peroxide produced at a liquid/liquid interface using scanning electrochemical microscopy

Hubert Girault, Fernando Cortes Salazar, Bin Su, Raheleh Partovi Nia

Scanning electrochemical microscopy (SECM) was used to monitor in situ hydrogen peroxide (H2O2) produced at a polarized water/1,2-dichloroethane (DCE) interface. The water/DCE interface was formed between a DCE droplet containing decamethylferrocene (DMFc) ...

Comparative dissolution kinetics of biogenic and chemogenic uraninite under oxidizing conditions in the presence of carbonate

Rizlan Bernier-Latmani, Harish Veeramani, Jonathan Sharp

The long-term stability of biogenic uraninite with respect to oxidative dissolution is pivotal to the success of in situ bioreduction strategies for the subsurface remediation of uranium legacies. Batch and flow-through dissolution experiments were conduct ...

H2O2 generation by decamethylferrocene at a liquid | liquid interface

Hubert Girault, Anne-Clémence Corminboeuf, Michel Prudent, Bin Su, Mohamad Hojeij, Raheleh Partovi Nia, Zdenek Samec

Hydrogen peroxide generation at a liquid|liquid interface occurs with a yield of 20 % with respect to the concentration of reducing agent (decamethylferrocene). The liquid|liquid interface supplies electrons from the reducing agent and protons from the aqu ...

Fabrication of gold nano- and microstructures in ionic liquids - A remarkable anion effect

Paul Joseph Dyson, Zhaofu Fei

Au nano- and microstructures such as polyhedral crystals, large single-cryst. nanoplates, hollow trapeziform crystals, holey polyhedra, and dendrites were produced via microwave heating of HAuCl4·4H2O in a variety of ionic liqs. (ILs) in the absence of cap ...
