Cellulose fibers modification through metal-free click chemistry for the elaboration of versatile functional surfaces

Alex Meye Biyogo, Louise Hespel, Vincent Humblot, Laurent Lebrun, François Estour

In the present work, a novel and versatile way was developed to functionalize cellulose fibers from wipes under heterogeneous conditions. The technic was based on metal-free click chemistry to avoid the persistence of any metal traces on cellulose. First, cellulose fibers were covalently pre-…

Cation Migration and Structural Deformations upon Dehydration of Nickel-Exchanged NaY Zeolite: A Combined Neutron Diffraction and Monte Carlo Study

Wilfried Louisfrema, Jean-Louis Paillaud, Florence Porcher, Elsa Perrin, Thomas Onfroy, Pascale Massiani, Anne Boutin, Benjamin Rotenberg

Combining neutron diffraction and classical molecular simulations, we describe the cation migration and associated structural changes taking place in a Ni-exchanged NaY faujasite zeolite upon stepwise dehydration from room temperature up to 400 °C. The cation redistribution between sites and the…

The state of BEA zeolite supported nickel catalysts in CO2 methanation reaction

Wojciech Gac, Witold Zawadzki, Grzegorz Słowik, Marcin Kuśmierz, Stanislaw Dzwigaj

Two model nickel catalysts for CO2 methanation reaction were prepared by the impregnation method using unmodified and dealuminated BEA-type zeolite supports, denoted NiHAlBEA and NiSiBEA. Transmission electron microscopy (TEM) and X-ray diffraction studies evidenced formation of metallic nickel…

Unraveling the Direct Decomposition of NO x over Keggin Heteropolyacids and Their Deactivation Using a Combination of Gas-IR/MS and In Situ DRIFT Spectroscopy

Josefine Schnee, Laurent Delannoy, Guylène Costentin, Cyril Thomas

Keggin heteropolyacids (HPAs) have been known to be efficient NOx absorbers for many years, and to decompose a significant fraction of the NOx species pre-absorbed at 100-150 °C into harmless N2 and O2 upon rapid heating to 450 °C. However, this capability of Keggin HPAs to directly decompose NOx…

Generation of pits on CoCrFeMnNi high entropy alloy: an electrochemical impedance study of a single event

Yaojun Hou, Oumaïma Gharbi, Kevin Ogle, Fan Sun, Mireille Turmine, Vincent Vivier

In this study, a single pit was successfully generated on the surface of a CoCrFeMnNi alloy using a home-made device consisting of an electrochemical work station coupled with a microflow-cell. The three-dimensional morphology of the single pit was observed by optical microscopy, revealing that the…

Optimizing the immobilization of gold nanoparticles on functionalized silicon surfaces: amine- vs thiol-terminated silane

Maroua Ben Haddada, Juliette Blanchard, Sandra Casale, Jean-Marc Krafft, Anne Vallée, Christophe Méthivier, Souhir Boujday

Immobilization of gold nanoparticles on planar surfaces is of great interest to many scientific communities; chemists, physicists, biologists, and the various communities working at the interfaces between these disciplines. Controlling the immobilization step, especially nanoparticles dispersion…

Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…
