Electrochemical Stability of Imidazolium Based Ionic Liquids Containing Cyano Groups in the Anion: A Cyclic Voltammetry, XPS and DFT Study

Paul Joseph Dyson, Zhaofu Fei, Alexander Wokaun

The electrochemical stability of ionic liquids based on the 1-ethyl-3-methyl imidazolium EMIM cation and three different anions, dicyanoamide (N(CN)(2)), tricyanomethanide (C(CN)(3)) and tetracyanoborate (B(CN)(4)), has been investigate ...

Cr-poisoning in (La,Sr)(Co,Fe)O-3 cathodes after 10,000 h SOFC stack testing

Jan Van Herle, Aïcha Hessler-Wyser, Zacharie Wuillemin, Josef Andreas Schuler

After 10,000 h solid oxide fuel cell (SOFC) stack operation, the Cr-poisoning situation in (La0.6Sr0.4) (Co0.2Fe0.8)O-3 (LSCF)-based cathode material is depicted in this work. Systematic Cr profiling by energy-dispersive X-ray spectroscopy (EDS), from post ...

Effective hydrogen diffusion coefficient for solidifying aluminium alloys

Michel Rappaz, Ludger Weber, Milan Felberbaum

An effective hydrogen diffusion coefficient has been calculated for two solidifying Al - 4.5 wt.% Cu and Al - 10 wt.% Cu alloys as a function of the volume fraction of solid. For this purpose, in situ X-ray tomography was performed on these alloys. For eac ...

VHDL-AMS Model of an Electrochemical Cell to Design VLSI Bio-Chips

Giovanni De Micheli, Sandro Carrara, Yusuf Leblebici, Alain Vachoux, Marialaura Beltrandi

This paper presents a new VHDL-AMS behavioral model of an electrochemical cell suitable for the design of VLSI bio-chips. Existing models are mainly equivalent circuit macromodels using electrical primitives, which hardly fit the actual behavior of biosens ...

Evaluation of Gibbs Energy of Dioxouranium Transfer at an Electrified Liquid vertical bar Liquid Interface Supported on a Microhole

Hubert Girault, Astrid Johana Olaya Avendano, Manuel Alejandro Méndez Agudelo, Thomas James Stockmann, Zhifeng Ding

Herein is reported the determination of the Gibbs energy of dioxouranium (UO22+) transfer across an interface between two immiscible electrolytic solutions (ITIES), water and 1,2-dichloroethane, that was supported at a 25 mu m diameter microhole, by means ...

Photomodulated Voltammetry of Iodide/Triiodide Redox Electrolytes and Its Relevance to Dye-Sensitized Solar Cells

Ulf Anders Hagfeldt

Photo-modulated voltammetry was used to det. the redox potentials of the diiodide radical (I2-·) in H2O, MeCN, and 3-methoxypropionitrile. Iodide/triiodide redox electrolytes were exposed to modulated blue light, resulting in I2-· generation. Using transpa ...

Performance of SOFC stacks under partial internal reforming of methane

Jan Van Herle, Stefan Diethelm

Solid Oxide Fuel Cell systems (SOFC) are developed for their electrical efficiency and versatility. Versatility stems from their tolerance towards CO and CH4, which allows for the use of various reformed fuels. Efficiency results from the direct conversion ...

Synaptic Mechanisms Underlying Sparse Coding of Active Touch

Carl Petersen, Sylvain Crochet, Yves Emile Alfred Kremer, James Poulet

Sensory information is actively gathered by animals, but the synaptic mechanisms driving neuronal circuit function during active sensory processing are poorly understood. Here, we investigated the synaptically driven membrane potential dynamics during acti ...

Nernst effect in the cuprate superconductor YBa_{2}Cu_{3}O_{y}: Broken rotational and translational symmetries

Johan Juul Chang

The Nernst coefficient of the cuprate superconductor YBa2Cu 3Oy was recently shown to become strongly anisotropic within the basal plane when cooled below the pseudogap temperature T, revealing that the pseudogap phase breaks the fourfold rotational symmet ...

Cell-Permeable Ln(III) Chelate-Functionalized InP Quantum Dots As Multimodal Imaging Agents

Marinella Mazzanti

Quantum dots (QDs) are ideal scaffolds for the development of multimodal imaging agents, but their application in clinical diagnostics is limited by the toxicity of classical CdSe QDs. A new bimodal MRI/optical nanosized contrast agent with high gadolinium ...
