The Prevailing Role of Hotspots in Plasmon-Enhanced Sum-Frequency Generation Spectroscopy

Laetitia Dalstein, Christophe Humbert, Maroua Ben Haddada, Souhir Boujday, Grégory Barbillon, Bertrand Busson

The plasmonic amplification of nonlinear vibrational sum frequency spectroscopy (SFG) at the surfaces of gold nanoparticles is systematically investigated by tuning the incident visible wavelength. The SFG spectra of dodecanethiol-coated gold nanoparticles chemically deposited on silicon are…

Silane Layers on Silicon Surfaces: Mechanism of Interaction, Stability, and Influence on Protein Adsorption

Nesrine Aissaoui, Latifa Bergaoui, Jessem Landoulsi, Jean-François Lambert, Souhir Boujday

In this work the mechanism of (3-aminopropyl)triethoxysilane (APTES) interaction with silicon surfaces is investigated at the molecular level. We studied the influence of experimental parameters such as time, temperature, and concentration on the quality of the APTES layer in terms of chemical…

Identification of a Ubiquinone-Ubiquinol Quinhydrone Complex in Bacterial Photosynthetic Membranes and Isolated Reaction Centers by Time-Resolved Infrared Spectroscopy

Alberto Mezzetti, Jean-Francois Paul, Winfried Leibl

Ubiquinone redox chemistry is of fundamental importance in biochemistry, notably in bioenergetics. The bi-electronic reduction of ubiquinone to ubiquinol has been widely studied, including by Fourier transform infrared (FTIR) difference spectroscopy, in several systems. In this paper, we have…

The Formation of Gold Clusters Supported on Mesoporous Silica Material Surfaces: A Molecular Picture

A. Wojtaszek, I. Sobczak, M. Ziolek, Frederik Tielens

The interaction of gold particles with a silica surface is investigated using a combination of theor. and exptl. techniques. It is found that the physisorption strength of gold on silica decreases with increasing chloride concn. at the surface, with increasing cluster size, and with decreasing…

Mechanistic Study of Cast and 3D-Printed Stainless Steel Electropolishing in Acid Media and Deep Eutectic Solvents

Chloé Rotty, Marie-Laure Doche, Audrey Mandroyan, Vincent Vivier, Jean-Yves Hihn

The mechanistic analysis of the electropolishing procedure of stainless steel (SS) was revisited using electrochemical impedance spectroscopy. Firstly, the control of the dissolution reaction by diffusion was confirmed with the linear dependence of the limiting current density as a function of the…
