Supercapacitive Admittance Tomoscopy

Hubert Girault, Jean-Pierre Abid

A sensor for measuring adsorption on a substrate has been designed including a contactless detection scheme, called supercapacitive admittance tomoscopy (SCAT). The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side ...

Adsorption and photoreactivity of CdSe nanoparticles at liquid|liquid interfaces

Hubert Girault, Bin Su, Jean-Pierre Abid, Nicolas Eugster

The voltage induced assembly and photoreactivity of cadmium selenide (CdSe) nanoparticles protected by mercaptosuccinic acid are studied at the polarisable interface between water and 1,2-dichloroethane electrolyte solutions. Cyclic voltammograms and admit ...

Self-assembled organic monolayers on gold nanoparticles: A study by sum-frequency generation combined with UV-vis spectroscopy

Hubert Girault, Jean-Pierre Abid

We use sum-frequency generation spectroscopy (SFG) in the infrared 2800–3000 cm−1 spectral range and UV–vis spectroscopy (transmission) in the 450–650 nm spectral range in order to characterize vibrational and electronic properties of various interfaces co ...

Size-Selective Separation of Gold Nanoparticles using Isoelectric Focusing Electrophoresis (IEF)

Hubert Girault, Christophe Roussel, Jean-Pierre Abid

Isoelectric focusing in a polyacrylamide pH gradient gel is used to analyze the size distribution of gold nanoparticles synthesized by a chemical route with mercaptosuccinic acid as a ligand. The isoelectric point of the nanoparticles is shown to be size d ...
