Redox Levels through Constant Fermi-Level ab Initio Molecular Dynamics

We develop a method to determine redox levels of half reactions through the use of ab initio molecular dynamics evolving at constant Fermi energy. This scheme models the effect of an electrode by controlling the charge transfer between the single-particle ...

Electrovariable gold nanoparticle films at liquid–liquid interfaces: from redox electrocatalysis to Marangoni-shutters

Hubert Girault, Pekka Eero Peljo, Evgeny Smirnov, Grégoire Clément Gschwend

Control over the physical properties of nanoparticle assemblies at a liquid–liquid interface is a key technological advancement to realize the dream of smart electrovariable nanosystems. Electrified interfaces, such as the interface between two immiscible ...

Contact potentials, Fermi level equilibration and surface charging

Hubert Girault, Pekka Eero Peljo

This paper focuses on contact electrification from thermodynamic equilibration of the electron electrochemical potentials of two conductors upon contact. The contact potential difference generated in bimetallic macro- and nanosystems, the Fermi level after ...

Charge distribution and Fermi level in bimetallic nanoparticles

Pekka Eero Peljo

Upon metal-metal contact, a transfer of electrons will occur between the metals until the Fermi levels in both phases are equal, resulting in a net charge difference across the metal-metal interface. Here, we have examined this contact electrification in b ...

High energy density MnO4– / MnO42– redox couple for alkaline redox flow batteries

Hubert Girault, Pekka Eero Peljo, Alejandro Nicolás Colli

The MnO4–/MnO42– redox couple has a positive redox potential, high electrochemical reversibility and high solubility, up to 3.62 M at room temperature. Careful optimization of the electrolyte composition and the potential limits eliminates the side reactio ...

Surface Plasmon Resonance of Nanoparticles and Applications in Imaging

Pierre Robert Maurice Millien

In this paper we provide a mathematical framework for localized plasmon resonance of nanoparticles. Using layer potential techniques associated with the full Maxwell equations, we derive small-volume expansions for the electromagnetic fields, which are uni ...

Direct observation of charge separation on Au localized surface plasmons

Giulia Tagliabue, Mercedes Hannelore Rittmann-Frank, Fabio Giacomo Santomauro

Plasmonic nano-structures of d(10) metals are suggested to be the future of photo-voltaics and photo-catalysis under solar irradiation, thanks to their large light absorption cross-section, versatility, and stability. We investigated the impact of continuo ...

Regeneration and recombination kinetics in cobalt polypyridine based dye-sensitized solar cells, explained using Marcus theory

Michael Graetzel, Mohammad Khaja Nazeeruddin, Ulf Anders Hagfeldt

Regeneration and recombination kinetics was investigated for dye-sensitized solar cells (DSCs) using a series of different cobalt polypyridine redox couples, with redox potentials ranging between 0.34 and 1.20 V vs. NHE. Marcus theory was applied to explai ...

LSPR properties of metal nanoparticles adsorbed at a liquid–liquid interface

Hubert Girault, Pingping Fang

Unlike the solid–air and solid–liquid interfaces, the optical properties of metal nanoparticles adsorbed at the liquid–liquid interface have not been theoretically exploited to date. In this work, the three dimensional finite difference time domain (3D-FDT ...
