Design of Mixed PEO/PAA Brushes with Switchable Properties Toward Protein Adsorption

M.F. Delacroix, G.L. Huet, T. Conard, S. Demoustier-Champagne, Filip E. Du Prez, Jessem Landoulsi, C.C. Dupont-Gillain

Adsorption of proteins at interfaces is an ubiquitous phenomenon of prime importance. Layers of poly(ethylene oxide) (PEO) are widely used to repel proteins. Conversely, proteins were shown to adsorb deeply into brushes of poly(acrylic acid) (PAA), and their subsequent partial release could be…

On the relationship between the basicity of a surface and its ability to catalyze transesterification in liquid and gas phases: the case of MgO

Damien Cornu, Hazar Guesmi, Guillaume Laugel, Jean-Marc Krafft, Hélène Lauron-Pernot

Gas or liquid phase transesterification reactions are used in the field of biomass valorization to transform some platform molecules into valuable products. Basic heterogeneous catalysts are often claimed for these applications but the role of basicity in the reaction mechanism depending on the…

TOOTHMIMIC : enzyme-assisted mineralization for the design of biomimetic enamel, TOOTHMIMIC : minéralisation assistée par enzyme pour la conception d'émail biomimétique

Brittany Foley

Biomineralization is the intricately-regulated process by which living organisms form hierarchically ordered mineralized materials. In the human body, the hard tissues are formed of calcium phosphate mineral composites with unique architectures that provide unparalleledmaterial properties. While…, La biominéralisation est le processus complexe par lequel les organismes vivants forment des matériaux minéralisés hiérarchiquement organisés. Dans le corps humain, les tissus durs sont formés de composites minéraux de phosphate de calcium avec des architectures uniques qui fournissent des…

Mesoporous nickel-alumina catalysts derived from MIL-53(Al) metal-organic framework: A new promising path for synthesizing CO2 methanation catalysts

Leila Karam, Maria C Bacariza, José M Lopes, Carlos Henriques, Julien Reboul, Nissrine El Hassan, Pascale Massiani

A new synthesis route for the preparation of highly efficient and stable porous Ni-based alumina catalysts for CO2 methanation is presented. It is based on the use of MIL-53(Al), an Al-containing metal-organic framework (MOF) with high surface area, as sacrificial support. A series of Ni-Al2O3…

Surface plasmon resonance biosensors incorporating gold nanoparticles.

Erin Bedford, Jolanda Spadavecchia, Claire-Marie Pradier, Frank Gu

SPR biosensing is increasingly popular for the detection of a multitude of biomolecules. It offers label-free detection and study of proteins, nucleic acids, and other biomolecules in real time. A recent trend involves incorporation of AuNPs, either within the sensing surface itself or as signal…

Bioconjugated gold nanorods to enhance the sensitivity of FT-SPR-based biosensors

Jolanda Spadavecchia, Sandra Casale, Souhir Boujday, Claire-Marie Pradier

n this paper, we report a feasible solvent-free approach for the synthesis and self-assembling of gold nanorods after bioconjugation to antibodies; scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images revealed a remarkable shape and size narrow distribution, as well…

New insights into the development of Brønsted acidity of niobic acid

Vanessa Lebarbier, Marwan Houalla, Thomas Onfroy

The development of Brønsted acidity and the relationship between acidity, catalytic performance and structure of niobium oxide were investigated for a series of samples prepared by calcination of niobic acid at temperatures between 423 and 823 K. All solids were active for propan-2-ol dehydration.…

Characterization of mesoporous alumina prepared by surface alumination of SBA-15

Manuel Baca, Emmanuel de La Rochefoucauld, Emmanuelle Ambroise, Jean-Marc Krafft, Redouane Hajjar, Pascal P. Man, Xavier Carrier, Juliette Blanchard

Mesoporous aluminas of controlled pore sizes were synthesized by multiple grafting of Al isopropoxide in organic solvents on mesoporous silica SBA-15. These materials were characterized by N2 physisorption, TEM, XRD, 27Al NMR and their surface chemical properties were probed by DRIFT, cumene…

ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…
