Electronic structure investigation of biphenylene films

R. Totani, C. Grazioli, Tiantian Zhang, I. Bidermane, J. Lüder, M. de Simone, M. Coreno, B. Brena, L. Lozzi, C. Puglia

Photoelectron Spectroscopy (PS) and Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy have been used to investigate the occupied and empty density of states of biphenylene films of different thicknesses, deposited onto a Cu(111) crystal. The obtained results have been compared to…

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…

Evidence of Pd segregation and stabilization at edges of AuPd nano-clusters in the presence of CO: A combined DFT and DRIFTS study

Beien Zhu, Gode Thrimurthulu, Laurent Delannoy, Catherine Louis, Christine Mottet, Jerome Creuze, Bernard Legrand, Hazar Guesmi

Combined Density Functional Theory (DFT) calculations and Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) were performed to study the distribution of Pd atoms in bimetallic AuPd nanoparticles in the presence of adsorbed CO. Compared to vacuum condition, the results showed…

True Circular Dichroism in Optically Active Achiral Metasurfaces and Its Relation to Chiral Near-Fields

Mathieu Nicolas, Per Magnus Walmsness, Jayeeta Amboli, Lu Zhang, Guillaume Demesy, Nicolas Bonod, Souhir Boujday, Morten Kildemo, Bruno Gallas

Optically active achiral metasurfaces offer a promising way to detect chiral molecules based on chiroptic methods. The combination of plasmonic enhanced circular dichroism and reversible optical activity would boost the sensitivity and provide enantiomerselective surfaces while using a single…

Elaboration de catalyseurs hétérogènes en milieu liquide ionique : nanoparticules métalliques (Au et Au-Pd) supportées sur dioxyde de titane, Heterogeneous catalysts preparation in ionic liquid media : titania-supported metallic nanoparticles (Au and Au-Pd)

Camella Oumahi

Ces travaux portent sur l'élaboration de catalyseurs hétérogènes en milieu liquide ionique (LI). Ces sels liquides à température ambiante permettent d'ajuster les propriétés du solvant suivant la composition chimique du LI mis en jeu (sels d'imidazolium ou Deep Eutectic Solvent à…, This work deals with the elaboration of heterogeneous catalysts in ionic liquids (ILs). These salts, liquid at room temperature, were chosen because they permit to adjust the solvent properties depending on their chemical composition (imidazolium salts or Deep Eutectic Solvent based on choline…

Chiral self-assemblies of amino-acid molecules: D- and L-methionine on Au(111) surface

Ahmed Naitabdi, Vincent Humblot

Spontaneous self-assembly into chiral well-ordered two-dimensional molecular film at room temperature has been evidenced using the scanning tunneling microscopy for the growth of two enantiomerically pure L- and D-methionine on Au(111) surface. From the x-ray photoelectron spectroscopy measurements…

Potential Role of Inorganic Confined Environments in Prebiotic Phosphorylation

Avinash Vicholous Dass, Maguy Jaber, André Brack, Frédéric Foucher, Terence P Kee, Thomas Georgelin, Frances Westall

A concise outlook on the potential role of confinement in phosphorylation and phosphate condensation pertaining to prebiotic chemistry is presented. Inorganic confinement is a relatively uncharted domain in studies concerning prebiotic chemistry, and even more so in terms of experimentation.…
