Thermodynamic brønsted basicity of clean MgO surfaces determined by their deprotonation ability: Role of Mg2+–O2 pairs

Céline Chizallet, Marie Laurence Bailly, Guylène Costentin, Hélène Lauron-Pernot, Jean Marc Krafft, Philippe Bazin, Jacques Saussey, Michel Che

The deprotonation ability of clean (i.e., carbonate- and hydroxyl-free) MgO surfaces of various morphologies towards protic molecules, such as propyne and methanol, is evaluated by following the adsorption modes and amount of dissociated species by FTIR. Photoluminescence is used to identify the…

1H MAS NMR study of the coordination of hydroxyl groups generated upon adsorption of H2O and CD3OH on clean MgO surfaces

Céline Chizallet, Guylène Costentin, Hélène Lauron-Pernot, Jocelyne Maquet, Michel Che

The coordination of OH groups on MgO has been characterized by 1H MAS NMR after appropriate pre-treatment conditions to obtain surfaces free from carbonates and with a controlled degree of hydroxylation. On MgO-sol–gel sample treated at 1023 K under flowing nitrogen, hydroxylated with water and…

Sorption of Cu(II) onto vineyard soils: macroscopic and spectroscopic investigations

Eric Marceau, Lorenzo Stievano

The sorption of Cu on five vineyard soils was examined via macroscopic and spectroscopic investigations. The composition of the soils was previously determined using X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). X-ray absorption spectroscopy (XAS) was employed to determine the…

A DNA biosensor based on peptide nucleic acids on gold surfaces

Eva Mateo-Marti, C. Briones, Claire-Marie Pradier, Jose A. Martin-Gago

We present a DNA biosensor based on self assembled monolayers (SAMs) of thiol-derivatized Peptide nucleic acid (PNA) chains adsorbed on gold surfaces for recognizing complementary ssDNA. PNA molecules tend to realign their molecular axes parallel to the surface normal and form SAMs on gold surfaces…

Revealing the Band Structure of FAPI Quantum Dot Film and Its Interfaces with Electron and Hole Transport Layer Using Time Resolved Photoemission

Dylan Amelot, Prachi Rastogi, Bertille Martinez, Charlie Gréboval, Clément Livache, Francesco Andrea Bresciani, Junling Qu, Audrey Chu, Mayank Goyal, Sang-Soo Chee, Nicolas Casaretto, Xiang Zhen Xu, Christophe Méthivier, Hervé Cruguel, Abdelkarim Ouerghi, Angshuman Nag, Mathieu G Silly, Nadine Witkowski, Emmanuel Lhuillier

Lead halide perovskite nanocrystals have attracted attention in the field of nanocrystal-based light-emitting diode and solar cells, because their devices showed high performances in only a few years. Among them, CsPbI3 is a promising candidate for solar cell design in spite of a too wide band gap…

Atomic Scale Observation of the Structural Dynamics of Supported Gold Nanocatalysts under 1,3‐Butadiene by in situ Environmental Transmission Electron Microscopy

Abdallah Nassereddine, Laurent Delannoy, Christian Ricolleau, Catherine Louis, Alloyeau D., Guillaume Wang, Qing Wang, Hazar Guesmi, Jaysen Nelayah

Supported gold catalysts have been reported to exhibit exceptional selectivity towards the desirable product, an alkene, in chemoselective hydrogenation of highly unsaturated alkynes and alkadienes. However, insights on the interactions between the gold nanoparticles and the 1,3‐butadiene…
