The Jones–Ray Effect Is Not Caused by Surface-Active Impurities

Sylvie Roke, Halil Ibrahim Okur, Eric Tyrode

Pure aqueous electrolyte solutions display a minimum in surface tension at concentrations of 2 ± 1 mM. This effect has been a source of controversy since it was first reported by Jones and Ray in the 1930s. The Jones–Ray effect has frequently been dismisse ...

Characterisation of neutron generators and monitoring detectors for the in-vessel calibration of JET

Olivier Sauter, Ambrogio Fasoli, Basil Duval, Stefano Coda, Martinus Gijs, Jonathan Graves, Yves Martin, Duccio Testa, Patrick Blanchard, Bruno Emanuel Ferreira De Sousa Correia, Alessandro Pau, Pierre-Thomas Paul Brun, Cristian Sommariva, Henri Weisen, Richard Pitts, Sun Hee Kim, Yann Camenen, Jan Horacek, Javier García Hernández, Marco Wischmeier, Mikhail Maslov, Nicola Vianello, Miguel Fernández Ruiz, Federico Nespoli, Antonio José Pereira de Figueiredo, Liang Yao, Yao Zhou, David Pfefferlé, Dalziel Joseph Wilson, Robin Humphry-Baker, Davide Galassi, José Pedro Rebelo Ferreira Marques, Ana Francisca Leal Silva Soares, Jonathan Marc Philippe Faustin, Daniel Scott Alessi, Arnout Lodewijk M Beckers, Julio Rodriguez, Hamish William Patten, Jonnathan Cesar Hidalgo Acosta, , , , , , , , ,

Not if, but when? Simulating the impact of timing the nuclear phase-out in Switzerland

Matthias Finger, Reinier Verhoog, Paul Adrianus Van Baal

Swiss electricity companies are faced with uncertainty with regards to the future operation of nuclear power plants in the country. After Fukushima in 2011, the government decided on a gradual phase-out, but only provided a tentative planning. Hence, no ne ...

Titanium carbide-carbon porous nanocomposite materials for radioactive ion beam production : processing, sintering and isotope release properties

João Pedro Fernandes Pinto Ramos

The Isotope Separator OnLine (ISOL) technique is used at the ISOLDE - Isotope Separator OnLine DEvice facility at CERN, to produce radioactive ion beams for physics research. At CERN protons are accelerated to 1.4 GeV and made to collide with one of two ta ...

Signatures of asymmetry in neutron spectra and images predicted by three-dimensional radiation hydrodynamics simulations of indirect drive implosions

Fabian Manke

We present the results of 3D simulations of indirect drive inertial confinement fusion capsules driven by the "high-foot" radiation pulse on the National Ignition Facility. The results are post-processed using a semi-deterministic ray tracing model to gene ...

Nickel-catalyzed Hydrosilylation of Alkenes and Transition-Metal-Free Intermolecular α-C-H Amination of Ethers

Ivan Buslov

Transition-metal-catalyzed hydrosilylation of olefins is one of the most important methods for the preparation of organosilicon compounds, which have broad applications in both synthetic and material chemistry. For decades, precious metals, principally pla ...

Development of Adsorbents for Selective Volatile Organic Compounds Removal from Diluted Gas Streams

Guillaume Bastien Baur

Contamination of the environment by anthropogenic volatile organic compounds (VOC) became of major concern during the last decades. Present in gas streams of many industrial exhausts, they are harmful and detrimental for both human health and environment e ...

Ferrocene-Based Tetradentate Schiff Bases as Supporting Ligands in Uranium Chemistry

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

Uranyl(VI), uranyl(V), and uranium(IV) complexes supported by ferrocene-based tetradentate Schiff-base ligands were synthesized, and their solid-state and solution structures were determined. The redox properties of all complexes were investigated by cycli ...

Mechanical work makes important contributions to surface chemistry at steps

William Curtin, Michael Frederick Francis

The effect of mechanical strain on the binding energy of adsorbates to late transition metals is believed to be entirely controlled by electronic factors, with tensile stress inducing stronger binding. Here we show, via computation, that mechanical strain ...

Probing nuclear rates with Planck and BICEP2

Julien Lesgourgues

Big-bang nucleosynthesis (BBN) relates key cosmological parameters to the primordial abundance of light elements. In this paper, we point out that the recent observations of cosmic microwave background anisotropies by the Planck satellite and by the BICEP2 ...

Electrochemical assessment of water|ionic liquid biphasic systems towards cesium extraction from nuclear waste

Thomas James Stockmann, Zhifeng Ding

A room temperature ionic liquid (IL) composed of a quaternary alkylphosphonium (trihexyltetradecylphosphonium, P66614(+)) and tetrakis(pentafluorophenyl) borate anion (TB) was employed within a water| P66614TB (w|P66614TB or w|IL) biphasic system to evalua ...
