Etude du front de minéralisation du tissu osseux et des modèles biomimétiques associés, Study of the mineralization front in bone tissue and in biomimetic models

Marc Robin

Les travaux réalisés ont pour but de répondre à deux questions : comment le collagène s'organise-t-il dans l'os mature ? Comment la phase minérale de l'os se forme-t-elle et quel est l'effet de son environnement sur sa formation ? Nous avons étudié d'un point de vue…, This work aims to understand: How is reached the plywood architecture in bone? How is bone apatite formed and what is the effect of the environment on apatite formation? Thus, histological bone thin sections were investigated focusing on the interface between the osteoid and mature bone tissues.…

Probing the in-air growth of large area of 3D functional structures into a 2D supramolecular nanoporous network

Romain Brisse, Dominique Guianvarc’h, Christelle Mansuy, Sandrine Sagan, David Kreher, Lydia Sosa-Vargas, Lydia Hamitouche, Vincent Humblot, Imad Arfaoui, Vanessa Labet, Céline Paris, Christophe Petit, André-Jean Attias

Surface-confined host–guest chemistry at the air/solid interface is used for trapping a functionalized 3D Zn–phthalocyanine complex into a 2D porous supramolecular template allowing the large area functionalization of an sp2-hybridized carbon-based substrate as evidenced by STM, resonance Raman…

Should W Surface Density of WOx-ZrO2 Catalysts Be Calculated With Respect To the Specific Surface Area of the Sample or That of ZrO2 Only?

Cyril Thomas

On the basis of the critical analysis of the NOx-TPD data obtained on WOx-ZrO2 samples [Law, H. Y.; Blanchard, J.; Carrier, X.; Thomas, C. J. Phys. Chem. C 2010, 114, 9731], this work provides convincing arguments for the first time upon which calculation of W surface density should be done by…

Electrospray ionization: an efficient approach to deposit polymetallic molecular switches onto gold surfaces

Amina Benchohra, Christophe Méthivier, Jessem Landoulsi, David Kreher, Rodrigue Lescouëzec

Electrospray ionization (EI) deposition is proven efficient in obtaining monolayers of a polymetallic charge transfer complex onto gold surfaces. The molecule's integrity is monitored by PM-IRRAS and XPS. This approach broadens the perspective of molecular magnetic switches' deposition,…

Unraveling the Mechanisms of Hypertrophy-Induced Matrix Mineralization and Modifications in Articular Chondrocytes

Ilhem Lilia Jaabar, Brittany Foley, Alberto Mezzetti, Françoise Pillier, Francis Berenbaum, Jessem Landoulsi, Xavier Houard

Chondrocyte hypertrophic differentiation is a main event leading to articular cartilage degradation in osteoarthritis. It is associated with matrix remodeling and mineralization, the dynamics of which is not well characterized during chondrocyte hypertrophic differentiation in articular cartilage.…

Polyol Process Coupled to Cold Plasma as a New and Efficient Nanohydride Processing Method: Nano-Ni 2 H as a Case Study

Sonia Haj-Khlifa, Sophie Nowak, Patricia Beaunier, Patricia de Rango, Michaël Redolfi, Souad Ammar-Merah

An alternative route for metal hydrogenation has been investigated: cold plasma hydrogen implantation on polyol-made transition metal nanoparticles. This treatment applied to a challenging system, Ni-H, induces a reordering of the metal lattice, and superstructure lines have been observed by both…

Evidence for Rh electron-deficient atoms (Rhdelta+) as the catalytic species for CO oxidation when supported on Ce0.68Zr0.32O2: a combined N2-FTIR, benzene hydrogenation and kinetic study

Céline Fontaine-Gautrelet, Jean-Marc Krafft, Gérald Djéga-Mariadassou, Cyril Thomas

The characterization of two low-loaded Rh(wt%)/Ce0.68Zr0.32O2 samples (Rh(0.29)/CZ and Rh(0.32)/CZ) was performed via N2-FTIR and benzene hydrogenation before being investigated for CO oxidation activity and kinetics. N2-FTIR allows characterization of both RhΔ+ (νN2 = 2295 cm-1) and Rh0 (νN2 =…
