Local Study on Hydrogen and Hydrogen Gas Bubble Formation on a Platinum Electrode

Hubert Girault, Andreas Stephan Lesch, Alberto Battistel, Christopher Raymond Dennison

This work investigates the effect of current density on the hydrogen gas bubble formation during electrolysis on a platinum electrode. Local detection of bubble evolution was performed electrochemically by using a hydrogen-collecting microelectrode placed ...

Rational design of ionic compounds for electrocatalytic reduction of carbon dioxide

Dmitry Vasilyev

Electrochemical reduction of carbon dioxide is one of the plausible approaches towards renewable energy carriers. When coupled with electricity, which can be provided by sustainable technologies, it becomes a method of high importance with potential value ...

3D multi-layer probe for application in neuroprosthetics

Diego Ghezzi, Marta Jole Ildelfonsa Airaghi Leccardi, Vivien Gaillet, Bastien Duckert

In neuroprosthetics, prostheses with higher and denser electrodes are needed to obtain both more precise recordings and targeted stimulations. The main limit is the routing of the active sites to the electronic control unit. A solution is to place electrod ...

Oxidatively Electrodeposited Thin-Film Transition Metal (Oxy)hydroxides as Oxygen Evolution Catalysts

Xile Hu, Laurent Liardet, Carlos Gilberto Morales Guio

The electrolysis of water to produce hydrogen and oxygen is a simple and attractive approach to store renewable energies in the form of chemical fuels. The oxygen evolution reaction (OER) is a complex four-electron process that constitutes the most energy- ...

Research Update: Platinum-elastomer mesocomposite as neural electrode coating

Stéphanie Lacour, Grégoire Courtine, Ivan Rusev Minev, Nikolaus Wenger

Platinum is electrochemically stable and biocompatible, and remains the preferred material for the fabrication of implantable neural electrodes. In a foil or film format, platinum is mechanically stiff compared to interfaced biological tissue. We report a ...

Multiwalled Carbon-Nanotube-Functionalized Microelectrode Arrays Fabricated by Microcontact Printing: Platform for Studying Chemical and Electrical Neuronal Signaling

Michele Giugliano, Luca Gambazzi

A facile method is proposed for the deposition of multiwalled carbon nanotube (MWCNT) layers onto microelectrode arrays by means of a microcontact printing technique, leading to the fabrication of MEAs characterized by well defined electrical and morpholog ...

Organic Redox Couples and Organic Counter Electrode for Efficient Organic Dye-Sensitized Solar Cells

Ulf Anders Hagfeldt

Org. thiolate/disulfide redox couples were synthesized and were studied systematically in dye-sensitized solar cells (DSCs) from an org. dye (TH305). Photophys., photoelectrochem., and photovoltaic measurements were performed to get insights into the effec ...

Solid electrochemical mass spectrometry (SEMS) for investigation of supported metal catalysts under high vacuum

Christos Comninellis, Wolfgang Harbich, Cyril Falgairette, Chun Xia

A new experimental set-up, coupling electrochemistry and mass spectroscopic techniques, for the investigation of a solid electrochemical cell under high vacuum conditions (HV) is presented. Two configurations are realized allowing the investigation of both ...
