Effect of Al2Cu precipitates size and mass transport on the polarisation behaviour of age-hardened Al-Si-Cu-Mg alloys in 0.05 M NaCl

The electrochemical behaviour of age-hardened Al-Si-Cu-Mg alloys was investigated in a 0.05 M NaCl solution under controlled mass transport conditions using a rotating disk electrode. This work aimed at getting better understanding of the effect of the all ...

Electrochemical Windows of Room-Temperature Ionic Liquids from Molecular Dynamics and Density Functional Theory Calculations

Nicola Marzari, Yihan Wu, Oliviero Andreussi

We investigated the cathodic and anodic limits of six room-temperature ionic liquids (ILs) formed from a combination of two common cations, 1-butyl-3-methylimidazolium (BMIM) and N,N-propylmethylpyrrolidinium (P13), and three common anions, PF6, BF4, and b ...

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 ...

A Novel Multi-Working Electrode Potentiostat for Electrochemical Detection of Metabolites

Giovanni De Micheli, Sandro Carrara, Cristina Boero, Michele Daniel Torre, Daniela De Venuto

A novel single-chip and multiplexed read-out circuit for multi-electrode electrochemical sensors, in standard 0.18 μm UMC CMOS technology, is presented. The circuit is a part of a fully-integrated biochip (in design) for the detection of multiple metabolit ...

Fountain pen for scanning electrochemical microscopy

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar, Dmitry Momotenko, Gunther Wittstock

A fountain pen probe has been developed to extend the scope of scanning electrochemical microscopy (SECM) experiments to dry surfaces. The fountain pen is fabricated by UV-photoablation of a polyethylene terephthalate (PET) film and consists on one side of ...

A surface locking instability for atomic intercalation into a solid electrode

William Curtin

By introducing a coupling between internal stresses and activation energy for diffusion in the classical theory of diffusion induced stresses, a class of nonconventional solutions has been found for atomic intercalation into a solid electrode, indicative o ...

Tribocorrosion behaviour of overlay welded Ni-Cr 625 alloy in sulphuric and nitric acids: Electrochemical and chemical effects

Stefano Mischler

The tribocorrosion behaviour of overlay welded Ni-Cr 625 alloy sliding against alumina in 0.5 M H2SO4 and 0.5 M HNO3 solutions under potentiostatic conditions was investigated. The passivation of the samples in the two electrolytes at different potentials ...

Ammonia oxidation to nitrogen mediated by electrogenerated active chlorine on Ti/PtOx-IrO2

Christos Comninellis, Agnieszka Kapalka, Nina-Luisa Michels

The electrochemical oxidation of ammonia (NH3 and/or NH4+) in the presence of chloride was investigated on a Ti/PtOx-IrO2 electrode. It was shown that ammonia is effectively removed from solution via electrogenerated active chlorine. Based on mass balances ...

A cell-electrode interface noise model for high-density microelectrode arrays

Alexandre Schmid, Yusuf Leblebici, Neil Joye

A cell-electrode interface noise model is developed which is dedicated to enable the co-simulation of the cell-electrode electrical characteristics, along with the electronics of novel CMOS-based MEA. The electrode noise is investigated for Pt and Pt black ...
