Abstract

The novel use of the scanning electrochemical microscope to follow the compression of a monolayer of monodisperse silver thiol-capped nanoparticles on a Langmuir trough is presented. The result reveals that the transition from an insulating to conductive behavior with compression can be followed.

Abstract

An investigation on the kinetics of heterogeneous electron transfer (ET) as a function of driving force at the interface between two immiscible electrolyte solutions using scanning electrochemical microscopy (SECM) is presented. The study concluded that at high driving force, experimental rate constants decreased with increasing overpotential, deviating from predictions based on Butler-Volmer kinetics.
