Preparation of Highly Anisotropic Cobalt Ferrite/Silica Microellipsoids Using an External Magnetic Field

Sébastien Abramson, Vincent Dupuis, Sophie Neveu, Patricia Beaunier, David Montero

Magnetic cobalt ferrite/silica microparticles having both an original morphology and an anisotropic nanostructure are synthesized through the use of an external magnetic field and nanoparticles characterized by a high magnetic anisotropy. The association of these two factors implies that the ESE (…

Oxidation of gold metal particles supported on TiO2: an FTIR study by means of low-temperature CO adsorption

Hr. Klimev, Katia Fajerwerg, K. Chakarova, L. Delannoy, C. Louis, K. Hadjiivanov

Two Au/TiO2 samples with different gold loadings (0.7 and 4.0 wt.% Au) were prepared by deposition-precipitation with urea and calcined at 673 K. TEM revealed gold particles of 3.2 and 3.9 nm for the 0.7 and 4.0 wt.% samples, respectively. The samples were subjected to different red-ox treatments…

Factors impacting protein adsorption on layer-by-layer assembled stimuli-responsive thin films

A. Osypova, C.-A. Fustin, C.-M. Pradier, Jessem Landoulsi, S. Demoustier-Champagne

Studying the stimuli-response of polyelectrolyte multilayers (PEMs) towards protein adsorption requires coping with the multiplicity of factors influencing interfacial processes. In this study, we report the design of a nanostructured stimuli-responsive coating based on the sequential layer-by…

Ethylene production from diluted bioethanol solutions

Ilenia Rossetti, Matteo Compagnoni, Giorgia de Guido, Laura A. Pellegrini, Gianguido Ramis, Stanislaw Dzwigaj

Ethylene production by ethanol dehydration has been investigated over a set of zeolites with BEA structure in acidic form (HAlBEA). The effect on Ni addition (up to 0.03 g/g (3 mass%)) is explored as a means to improve ethylene selectivity limiting the formation of heavier byproducts. The reaction…

Low-energy electron induced resonant loss of aromaticity: consequences on cross-linking in terphenylthiol SAMs

L. Amiaud, J. Houplin, M. Bourdier, V. Humblot, R. Azria, C.-M. Pradier, A. Lafosse

Aromatic self-assembled monolayers (SAMs) can be used as negative tone electron resists in functional surface lithographic fabrication. A dense and resistant molecular network is obtained under electron irradiation through the formation of a cross-linked network. The elementary processes and…

Investigation of the interface in silica-encapsulated liposomes by combining solid state NMR and first principles calculations.

Nicolas Folliet, Claire Roiland, Sylvie Bégu, Anne Aubert, Tzonka Mineva, Annick Goursot, Kaliaperumal Selvaraj, Luminita Duma, Frederik Tielens, Francesco Mauri, Guillaume Laurent, Christian Bonhomme, Christel Gervais, Florence Babonneau, Thierry Azaïs

In the context of nanomedicine, liposils (liposomes and silica) have a strong potential for drug storage and release schemes: such materials combine the intrinsic properties of liposome (encapsulation) and silica (increased rigidity, protective coating, pH degradability). In this work, an original…

Dual Thermo- and pH-Responsive N -Cyanomethylacrylamide-Based Nano-Objects Prepared by RAFT-Mediated Aqueous Polymerization-Induced Self-Assembly

Nicolas Audureau, Fanny Coumes, Jean-Michel Guigner, Clément Guibert, François Stoffelbach, Jutta Rieger

We report the straightforward synthesis of dual stimuli-responsive nano-objects using a RAFT-mediated polymerization-induced self-assembly (PISA) process in water. The key to complex and tunable responsiveness was the copolymerization of N-cyanomethylacrylamide, providing UCST-type polymers, with a…

Silane Layers on Silicon Surfaces: Mechanism of Interaction, Stability, and Influence on Protein Adsorption

Nesrine Aissaoui, Latifa Bergaoui, Jessem Landoulsi, Jean-François Lambert, Souhir Boujday

In this work the mechanism of (3-aminopropyl)triethoxysilane (APTES) interaction with silicon surfaces is investigated at the molecular level. We studied the influence of experimental parameters such as time, temperature, and concentration on the quality of the APTES layer in terms of chemical…
