'Green' Cr(iii)-glycine electrolyte for the production of FeCrNi coatings: electrodeposition mechanisms and role of by-products in terms of coating composition and microstructure

Stefano Mischler, Johann Michler, Enrico Bertero

The electrodeposition of stainless steel-like FeCrNi alloys for miniaturised devices is appealing as it would allow combining excellent material properties (e.g. corrosion resistance, hardness, biocompatibility) at low-cost. However, conventional baths oft ...

On-Site Purification of Copper-Contaminated Vanadium Electrolytes by using a Vanadium Redox Flow Battery

Hubert Girault, Heron Vrubel, Alberto Battistel, Christopher Raymond Dennison, Danick Reynard

Corrosion of carbon-based electrodes and bipolar plates is a major hurdle and can be a cause of failure in commercial vanadium redox flow batteries (VRFBs). Carbon corrosion was found to occur in a commercial VRFB (10 kW/40 kWh), whereby cracks through bip ...

Effect of the electrochemical characteristics of titanium on the adsorption kinetics of albumin

Anna Neus Igual Muñoz

An electrochemical quartz crystal microbalance (EQCM) was used to examine the electrochemical behaviour of pure titanium in phosphate buffered saline (PBS) and PBS-containing bovine serum albumin (BSA) solutions, and the associated adsorption characteristi ...

Tribological response of multilayered gold nickel coating deposited on fine turned surfaces

Stefano Mischler, Valentine Agnès Madeleine Magnin

Gold coating are widely used in industry due to their corrosion resistance, electrical conductivity and low contact resistance. However, friction and wear can limit their functionality and lifetime. This study addresses the degradation of a commercial fine ...

Chopped-Anodic-Phase Charge Balancing Method for Electrical Stimulation

Alexandre Schmid, Reza Ranjandish

Providing safety of stimulation is a critical requirement in the design of biomedical electrical stimulators. Charge balancing circuits are required to guarantee safety of electrical stimulators. Chopped-anodic-phase (CAP) is one of the methods used for ch ...

Semi-analytical modelling of linear scan voltammetric responses for soluble-insoluble system: The case of metal deposition

Hubert Girault, Imene Atek, Pekka Eero Peljo, Sunny Isaïe Maye

The absence of general theoretical models describing linear sweep voltammetry (LSV) or cyclic voltammetry (CV) responses for soluble-insoluble systems such as one-step electrodeposition reactions under quasi-reversible condition makes it difficult to extra ...
