Exploring the Reactivity of Framework Vanadium, Niobium, and Tantalum Sites in Zeolitic Materials Using DFT Reactivity Descriptors

Frederik Tielens

The acid-base properties of zeolites with group 5 transition metal framework sites are investigated, and a first step into the understanding of their acid/base and redox properties is undertaken using DFT reactivity descriptors. It is evidenced, using socialite as model system, that zeolites with…

Cation distributions on CoAl2O4 and Co2AlO4 spinels: pressure and temperature effects

R. Franco, Frederik Tielens, M. Calatayud, J. M. Recio

Structural, energetic and thermodynamic properties of CoAl2O4 and Co2AlO4 spinels are investigated using the density functional theory formalism. Thermal effects are incorporated by means of a non-empirical quasi-harmonic Debye-like model that allows us to study the influence of temperature on the…

Glycine Interaction with Geminal and Vicinal Silanols

D. Costa, Frederik Tielens, L. Stievano, J-F. Lambert

A periodic DFT study of the adsorption of glycine on an amorphous silica surface is presented. It is shown that glycine adsorbs via a specific interaction with the geminal silanols. Geminal silanols are the most reactive sites for glycine adsorption and the adsorption on these sites is irreversible…

Atomic level characterization and sulfur resistance of unsupported W2C during dibenzothiophene hydrodesulfurization. Classical kinetic simulation of the reaction

Marek Lewandowski, Agnieszka Szymanska-Kolasa, Céline Sayag, Patricia Beaunier, Gérald Djéga-Mariadassou

The stability of unsupported W2C tungsten carbide and its sulfur resistance during hydrodesulfurization (HDS) of dibenzothiophene (DBT) are a specificity of W2C. This material was characterized by X-ray diffraction, specific surface area measurements, HRTEM associated with EDS, lattice images,…

Bio-inspired calcium phosphate mineralization through enzymatic approach, Minéralisation de phosphate de calcium d'inspiration biologique par approche enzymatique

Jihye Lee

Biomineralization of calcium phosphate (CaP) is the process by which some organism builds hard mineralized tissues, such as bone, enamel and calcified cartilage. This process is regulated through various physicochemical factors and biochemical reactions, involving particularly matrix vesicles (MVs…, La biominéralisation du phosphate de calcium (CaP) est le processus par lequel un organisme construit des tissus minéralisés durs, tels que l'os, l'émail et le cartilage calcifié. Ce processus est régulé par divers facteurs physico-chimiques et réactions biochimiques, impliquant en…

Self-Assembly of Fatty Acids on Hydroxylated Al Surface and Effects of Their Stability on Wettability and Nanoscale Organization

Irma Liascukiene, Marie Steffenhagen, Svajus J. Asadauskas, Jean-François Lambert, Jessem Landoulsi

The self-assembly of fatty acids (FA) on the surfaces of inorganic materials is a relevant way to control their wetting properties. While the mechanism of adsorption on model flat substrate is well described in the literature, interfacial processes remain poorly documented on nanostructured…

Influence of synthesis parameters of SBA-15 supported palladium catalysts for methane combustion and simultaneous NOx reduction

Maya Boutros, María Elena Gálvez, Thomas Onfroy, Patrick da Costa

Several synthesis routes were followed to prepare ordered mesoporous silica, SBA-15, and alumino-silica, Al–SBA-15, supported palladium catalysts. Synthesis method as well as the nature of precursor used in the preparation of these catalysts strongly determined their physico-chemical features which…
