New Insights into Radical Mechanisms in Natural Drying Oils: Paint Binders as Reactors for Nanoparticle Formation

Laurence de Viguerie, Yongjie Yang, Fabrice Morlet-Savary, Jacques Lalevée, Sandra Casale, Christine Péchoux, Maguy Jaber, Gilles Patriarche

Understanding radical processes in drying oils is essential for both heritage science and materials chemistry, as these reactions govern film formation and long-term stability in historical paintings. In this study, we investigate radical mechanisms in linseed oil, a traditional paint binder. Gold…

Reactive Processing of Polyethylene with Azidotriazine: From Modified Thermoplastics to Injection Moldable Covalent Adaptable Networks

Huidi Sun, Thomas Vialon, Clément Guibert, Sandra Casale, Renaud Nicolaÿ, Nathan van Zee

The increasing consumption of polyethylene (PE) is an important concern for society because the rate of PE recycling remains low compared to the scale of PE production. There is thus great interest in strategies for revalorizing PE waste. In this context, our group recently reported an approach for…

High‐Resolution Corrosion Fingerprinting of Alloy Libraries via Microdroplet Spectroelectrochemistry

Ekaterina Kurchavova, Oumaïma Gharbi, Mireille Turmine, Vincent Vivier

A rapid and reliable methodology for assessing localized corrosion is essential for the early-stage of advanced alloy systems. Here, we present an ionic-liquid-based microdroplet electrochemical platform that overcomes the time limitations of conventional aqueous droplets by using nonvolatile…

Mesoporous materials from zeolite seeds as supports for nickel-tungsten sulfide active phases: Part 2. Catalytic properties for deep hydrodesulfurization reactions

Juliette Blanchard, Shuangqin Zeng, Michèle Breysse, Yahua Shib, Xintian Su, Hong Nie, Dadong Li

The properties of nickel-tungsten sulfide supported on MCM-41 aluminosilicate materials assembled from beta-zeolite seeds ([beta]-MCM-41) were examined in the conversion of 4,6-dimethyldibenzothiophene (4,6-DMDBT) pure or in mixture with dimethyldisulfide, carbazole and tetralin. As reported in the…

Evolution of nickel speciation from aqueous solution to the surface of Ni/SiO2: effect of the number of chelating ligands in [Ni(en)x(H2O)6-2x]2+

Michel Che, Eric Marceau, Ke Qiang Sun

The evolution of nickel speciation during the successive preparation steps of Ni–SiO2 catalysts is studied by UV-Vis-NIR, FT-IR, DTG, TPR and TEM. The study focuses on the effect of the number of chelating ligands in the precursor complexes [Ni(en)x(H2O)(6 2x)]2+ (en = ethylenediamine, x = 1, 2, 3…

Evidence for emission and transfer of energy from excited edge sites of MgO smokes by photoluminescence experiments.

Romain Hacquart, Jean-Marc Krafft, Guylène Costentin, Jacques Jupille

New features are observed in photoluminescence spectra of MgO smokes produced in controlled conditions, an experiment inspired by previous measurements on cleaved MgO(100). Upon photoexcitation at 5.17–5.45 eV, most luminescence spectra observed can be decomposed into two bands, peaking at 3.82–3.…

The synthesis and characterization of a series of mixed W-Zr polynuclear Lindqvist-type complexes, deriving from hexatungstate [W6O19]2-, are described in this work. This family of compounds is built from {W5O18Zr}2- moieties as shown by the X-ray structures of the monomeric [W5O18Zr(H2O)3-n(DMSO)n…
