Two dimensional diffusion-controlled triplet–triplet annihilation kinetics
Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Grégoire Clément Gschwend, Morgan Kazmierczak
Diffusion controlled chemical reactions are usually observed in three dimensionalmedia. In contrast, planar bimolecular reactions taking place between reagents adsorbed at a soft interface are two-dimensional and therefore cannot be studied within the same ...
2019Optical Second Harmonic Generation in Plasmonic Nanostructures: From Fundamental Principles to Advanced Applications
Olivier Martin, Pierre-François Marie Brevet, Jérémy Butet
Plasmonics has emerged as an important research field in nanoscience and nanotechnology. Recently, significant attention has been devoted to the observation and the understanding of nonlinear optical processes in plasmonic nanostructures, giving rise to th ...
American Chemical Society2015Gold Metal Liquid-Like Droplets
Hubert Girault, Pierre-François Marie Brevet, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Dmitry Momotenko, Evgeny Smirnov
Simple methods to self-assemble coatings and films encompassing nanoparticles are highly desirable in many practical scenarios, yet scarcely any examples of simple, robust approaches to coat macroscopic droplets with continuous, thick (multilayer), reflect ...
Amer Chemical Soc2014Ultrafast Population Dynamics of Surface-Active Dyes during Electrochemically Controlled Ion Transfer across a Liquid|Liquid Interface
Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Evgeny Smirnov
We present for the first time experimental measurements on the ultrafast population dynamics of the model surface-active dye methyl orange (MO) during its ion transfer across the water|1,2-dichloroethane interface by using time-resolved surface second harm ...
Amer Chemical Soc2014Universal scaling of plasmon coupling in metal nanostructures: Checking the validity for higher plasmonic modes using second harmonic generation
Olivier Martin, Pierre-François Marie Brevet, Jérémy Butet
The universal scaling of plasmon coupling in metallic nanostructures is now a well-established feature. However, if the interaction between dipolar plasmon modes has been intensively studied, this is not the case of the coupling between higher order ones. ...
Amer Physical Soc2013Interfacial Self-Assembly of Water-Soluble Cationic Porphyrins for the Reduction of Oxygen to Water
Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet
Meet at the border: Assembly of the water-soluble cobalt tetrakis(N-methylpyridinium-4-yl)porphyrin [CoTMPyP]4+ at soft interfaces is enhanced and stabilized by its interfacial interaction with the lipophilic anion (C6F5)4B−. The supramolecular structure t ...
2012Self-Assembled Molecular Rafts at Liquid|Liquid Interfaces for Four-Electron Oxygen Reduction
Hubert Girault, Jiri Vanicek, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet, Tomas Zimmermann
The self-assembly of the oppositely charged watersoluble porphyrins, cobalt tetramethylpyridinium porphyrin (CoTMPyP4+) and cobalt tetrasulphonatophenyl porphyrin (CoTPPS4−), at the interface with an organic solvent to form molecular “rafts”, provides an e ...
2012Controlled Reversible Adsorption of Core-Shell Metallic Nanoparticles at the Polarized Water/1,2-Dichloroethane Interface Investigated by Optical Second-Harmonic Generation
Hubert Girault, Christophe Bauer, Pierre-François Marie Brevet, Jean-Pierre Abid
We report the observation of the reversible adsorption of core-shell gold-silver nanoparticles at the polarized water/1,2-dichloroethane interface using the nonlinear optical technique of surface second-harmonic generation. This study unambiguously demonst ...
2007Second harmonic generation response by gold nanoparticles at the polarized water/2-octanone interface: from dispersed to aggregated particles
Hubert Girault, Pierre-François Marie Brevet
Gold nanoparticles with a diameter of approximately 20 nm have been observed at the polarized water/2-octanone interface by the nonlinear optical technique of second harmonic generation. Electric field induced adsorption of the gold particles at this liqui ...
2007Hyper-Rayleigh scattering of gold nanorods and their relationship with linear assemblies of gold nanospheres
Hubert Girault, Pierre-François Marie Brevet, Jean-Pierre Abid
The surface plasmon enhanced hyper-Rayleigh scattering light collected from an aqueous solution of gold nanorods is reported. A non negligible part of the signal is attributed to a photoluminescence background attributed to the electron–hole recombination ...
