Investigation of an Allergen Adsorption on Amine- and Acid-Terminated Thiol Layers: Influence on Their Affinity to Specific Antibodies

P. Thebault, Souhir Boujday, Helene Senechal, Claire-Marie Pradier

This work describes the controlled immobilization of a recognized allergen, beta-lactoglobulin, onto gold transducers with the aim of optimizing the elaboration of a biosensor directed against allergen-produced antibodies. This protein was immobilized on both amine- and acid-terminated thiol self-…

Acidic Osteoid Templates the Plywood Structure of Bone Tissue

Marc Robin, Chakib Djediat, Arnaud Bardouil, Niki Baccile, Camille Chareyron, Ivo Zizak, Peter Fratzl, Mohamed Selmane, Bernard Haye, Isabelle Genois, Jean‐marc Krafft, Guylène Costentin, Thierry Azaïs, Franck Artzner, Marie‐madeleine Giraud-Guille, Paul Zaslansky, Nadine Nassif

Bone is created by osteoblasts that secrete osteoid after which an ordered texture emerges, followed by mineralization. Plywood geometries are a hallmark of many trabecular and cortical bones, yet the origin of this texturing in vivo has never been shown. Nevertheless, extensive in vitro work…

Increasing the efficiency of magnetic heterogeneous Fenton catalysts with a simple halogen visible lamp

Nassira Ferroudj, Delphine Talbot, Aude Michel, Anne Davidson, Sébastien Abramson

The effect of a simple visible halogen lamp was studied in the Fenton-type oxidation of three model aqueous pollutants differing in their structure and electrostatic charge, methylorange (MO), methylene blue (MB) and paranitrophenol (PNP), using maghemite nanoparticles (γ-Fe 2 O 3 NP), or maghemite…

Halide Ligands to Release Strain in Cadmium Chalcogenide Nanoplatelets and Achieve High Brightness

Marion Dufour, Junling Qu, Charlie Gréboval, Christophe Méthivier, Emmanuel Lhuillier, Sandrine Ithurria

Zinc blende II-VI semiconductor nanoplatelets (NPLs) are defined at the atomic scale along the thickness of the nanoparticle and are initially capped with carboxylates on the top and bottom [001] facets. These ligands are exchanged on CdSe NPLs with halides that act as X-L-type ligands. These CdSe…

The Acidity of Zeolites: Concepts, Measurements and Relation to Catalysis: A Review on Experimental and Theoretical Methods for the Study of Zeolite Acidity

E.G. Derouane, Jacques C. Vedrine, Ramos R. Pinto, P.M. Borges, L. Costa, M. A. N. D. A. Lemos, F. Lemos, Ramôa Ribeiro

In this article, we considered all aspects of acidity (nature of acid sites, strength, density, etc.) in solid catalysts and in zeolites in particular. After reminding the definition of acidity in liquid and solid acids, we emphasized acidity characterization by the most used physical techniques,…

Integrated stopped-flow device for the study of porous materials using hyperpolarized $^{129}$Xe NMR

Jing Li, Estelle Léonce, Corentin Coutellier, Céline Boutin, Kévin Chighine, Charles Rivron, Anne Davidson, Patrick Berthault

A simple, low-cost, and efficient device is proposed for the study of porous materials via NMR using small gas probes. Mainly built through additive manufacturing and being equipped with a radiofrequency solenoid microcoil, it only requires tiny quantities of sample and/or gas and is particularly…

Deciphering pathological remodelling of the human cartilage extracellular matrix in osteoarthritis at the supramolecular level

Ilhem Lilia Jaabar, Pauline Cornette, Antoine Miche, Kristell Wanherdrick, Vincent Dupres, François-Paul Ehkirch, Adeline Cambon Binder, Francis Berenbaum, Xavier Houard, Jessem Landoulsi

Osteoarthritis induces a combination of chemical, structural and nanomechanical changes to collagen fibrils and aggrecan aggregates, the main building blocks of cartilage ECM, that may be mimicked by specific enzymatic reactions.

Photochemistry of organic molecules in the Solar System: experimental studies outside the International Space Station. The cases of glycine, and nucleobases

E. Palumbo

Solar UV radiation is a major source of energy for initiating chemical evolution towards complex organic structures, but it can also photo-dissociate even the most complex molecules. Thus, solar UV can erase the organic traces of past life at the surface of planets, such as Mars, destroy organic…

Biominéralisation intracellulaire par des cyanobactéries : du modèle aux cellules, Intracellular biomineralization by cyanobacteria : from model to cells

Nithavong Cam

Cette thèse vise à avancer dans la compréhension de la formation récemment découverte de carbonates amorphes intracellulaires par des cyanobactéries. Des synthèses abiotiques ont permis de produire des carbonates similaires aux inclusions intracellulaires en termes de morphologie, structure et…, In this thesis we study the recently discovered formation of intracellular amorphous carbonates by cyanobacteria. Abiotic syntheses produced carbonates with a morphology, structure and composition similar as intracellular inclusions. The intracellular chemical conditions in the cyanobacteria can be…

Fatty Acid Monolayers on Randomly Nanostructured Inorganic Surfaces: Interplay of Wettability, Chemistry, and Topography

Mathieu Beauvais, Irma Liascukiene, Alain Jonas, Jessem Landoulsi

Understanding the wetting properties of chemically modified inorganic surfaces with random nanoscale topographies is of fundamental importance for diverse applications. This issue has hitherto continuously been the subject of considerable controversies. Herein, we report a thorough investigation of…
