Operando analysis of the electrosynthesis of Ag2O nanocubes by scanning electrochemical microscopy

Autor: Mathias Miranda Vieira, Jean-François Lemineur, Jérôme Médard, Catherine Combellas, Frédéric Kanoufi, Jean-Marc Noël

Publikováno v: Electrochemistry Communications, Vol 124, Iss , Pp 106950- (2021)

The strategy proposed herein employs the scanning electrochemical microscope in generation/ collection mode to clarify the mechanism involved in the electrosynthesis of metal oxide nanoparticles, NPs. It offers simultaneously both generation of the p

Approximate solutions of the transcendental equation for the square quantum wells by finding the real root of the cubic equation

Autor: Jean-Marc Noël, Luc Lévesque

Publikováno v: Canadian Journal of Physics.

The energy eigenvalues E n in finite square quantum wells (SQW) cannot be found using an analytic expression. As a result, numerical methods are normally used to find the eigenvalues from a transcendental equation. In this report, it will be shown th

Fuelling electrocatalysis at single nanoparticle by ion flow in a nanoconfined electrolyte layer

Autor: Louis Godeffroy, Viacheslav Shkirskiy, Jean-Marc Noël, Jean-François Lemineur, Frederic Kanoufi

Publikováno v: Faraday Discussions.

We explore the possibility of coupling the transport of ions and water in a nanochannel with the chemical transformation of a reactant at an individual catalytic nanoparticle (NP). Such configuration...

Highly Reactive Diazenyl Radical Species Evidenced during Aryldiazonium Electroreduction

Autor: Laure Pichereau, Laure Fillaud, Nikolaos Kostopoulos, Emmanuel Maisonhaute, Thomas Cauchy, Magali Allain, Jean-Marc Noël, Christelle Gautier, Tony Breton

Publikováno v: The journal of physical chemistry letters.

We report the experimental reassessment of the widely admitted concerted reduction mechanism for diazonium electroreduction. Ultrafast cyclic voltammetry was exploited to demonstrate the existence of a stepwise pathway, and real-time spectroelectroch

Bridging the Gap between Single Nanoparticle Imaging and Global Electrochemical Response by Correlative Microscopy Assisted By Machine Vision

Autor: Louis Godeffroy, Jean‐François Lemineur, Viacheslav Shkirskiy, Mathias Miranda Vieira, Jean‐Marc Noël, Frédéric Kanoufi

Publikováno v: Small methods. 6(9)

The nanostructuration of an electrochemical interface dictates its micro- and macroscopic behavior. It is generally highly complex and often evolves under operating conditions. Electrochemistry at these nanostructurations can be imaged both operando
