Thermal control of ionic transport and fluid flow in nanofluidic channels

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

In this work, we report a nanofluidic gating mechanism that uses the thermal effect for modulating the ionic transport inside nanofluidic channels. The control of the ionic transport inside a nanochannel is demonstrated using electrical conductivity. A the ...

Al2O3/W hetero-structured nanopore membranes: From native to tunable nanofluidic diodes

Jürgen Brugger, Philippe Renaud, Arnaud Bertsch, Fabien Patrick Wildhaber, Songmei Wu

We present here Al2O3/W hetero-structured nanopore membranes which function as native and electrical field tunable nanofluidic diodes. A typical membrane is 100×100 μm2 in size with pore density of ∼ 20/μm2. The nanopores are 26 nm in diameter and 400 nm i ...

An analysis of the optimal band gaps of light absorbers in integrated tandem photoelectrochemical water-splitting systems

Sophia Haussener

The solar-to-hydrogen (STH) efficiency limits, along with the maximum efficiency values and the corresponding optimal band gap combinations, have been evaluated for various combinations of light absorbers arranged in a tandem configuration in realistic, op ...

Statistical Analysis of Ion Mobility Spectrometry. II. Adaptively Biased Methods and Shape Correlations

Yury Tsybin

Following a recent effort [J. Am. Soc. Mass Spectrom. 23, 386-396 (2012)], we continue to explore computational methodologies for generating molecular conformations to support collisional cross sections suggested by ion mobility measurements. Here, adaptiv ...

Ion current rectification and rectification inversion in conical nanopores: a perm-selective view

Hubert Girault, Fernando Cortes Salazar, Dmitry Momotenko

Ionic transport in charged conical nanopores is known to give rise to ion current rectification. The present study shows that the rectification direction can be inverted when using electrolyte solutions at very low ionic strengths. To elucidate these pheno ...

Nd-Nickelate Solid Oxide Fuel Cell Cathode Sensitivity to Cr and Si Contamination

Jan Van Herle, Aïcha Hessler-Wyser, Josef Andreas Schuler, Henning Lübbe

The stability of Nd-nickelate, considered as an alternative solid oxide fuel cell (SOFC) cathode material, was evaluated in this work on its tolerance towards contaminants. Symmetrical cells with Nd1.95NiO4+δ (NNO) electrodes on gadolinia-doped ceria elect ...

External control of anodic dissolution mechanism of 100Cr6 in nitrate/chloride mixed electrolytes

Andreas Stephan Lesch, Gunther Wittstock

The anodic dissolution of 100Cr6 steel in neutral electrolytes containing sodium chloride and sodium nitrate was investigated potentiodynamically and galvanodynamically with a rotating disc electrode at room temperature. The total concentration of the mixe ...

Polymeric Ionic Liquids: Comparison of Polycations and Polyanions

Jutta Christine Wandrey

The achievement of high ionic conductivity in new "polymeric ionic liquids" (PILs) is of great interest as it refers to the solid state electrolytes and their applications in electrochemistry. Four ionic monomers, including two new ones, namely N-[(2-metha ...

Gel-free IEF in a membrane-sealed multicompartment cell for proteome prefractionation

Hubert Girault, Hoang-Trang Lam

A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
