Breaking boundaries in Electrochemistry: Unveiling a new dimensionless number to tackle convective transfer effect on the voltamperometric answer

Autor: Guillaume Hopsort, Cheikhou Kane, Fabien Chauvet, Laure Latapie, Theodore Tzedakis

Publikováno v: Electrochemistry Communications, Vol 163, Iss , Pp 107706- (2024)

This study introduces the Theokane number (Tk) as a groundbreaking dimensionless number in Electrochemistry. Tk enables the determination of the operating state of an electrochemical (EC) system—indicating whether it is in a transient state (charac

Crossover between Re-Nucleation and Dendritic Growth in Electrodeposition without Supporting Electrolyte

Autor: Fabien Chauvet, Théo Tzedakis, Chams Kharbachi

Publikováno v: Journal of The Electrochemical Society
Journal of The Electrochemical Society, Electrochemical Society, 2021, 168 (7), pp.072507. ⟨10.1149/1945-7111/ac15bb⟩

This work focuses on the microstructure of metallic deposits formed by galvanostatic electrodeposition inside a Hele-Shaw cell without both supporting electrolyte and flow. For a low applied current density j, the deposit grows under the form of rami

ssDNA degradation along capillary electrophoresis process using a Tris buffer

Autor: Audrey Ric, Varravaddheay Ong-Meang, Nathalie Martins-Froment, Véréna Poinsot, Laurent Paquereau, François Couderc, Audrey Boutonnet, Vincent Ecochard, Frédéric Ginot, Fabien Chauvet

Publikováno v: ELECTROPHORESIS. 38:1624-1631

Tris-Acetate buffer is currently used in the selection and the characterization of ssDNA by capillary electrophoresis (CE). By applying high voltage, the migration of ionic species into the capillary generates a current that induces water electrolysi
