Study of calixarenes thin films as chemical sensors for the detection of explosives

P. Montmeat, F. Veignal, C. Methivier, C.M. Pradier, L. Hairault

Calix(n)arenes (n = 4, 6, 8) are used as sensitive coatings for Quartz Crystal Microbalance (QCM)-based chemical sensors, and specially for the detection of dinitrotoluene as a model explosive molecule. Calix(n)arenes complex organic architectures were deposited by spray on gold-coated wafer…

Redox-Triggered Control of Cell Adhesion and Deadhesion on Poly(lysine)- g -poly(ethylene oxide) Adlayers

Louise Hespel, Julien Dupré de Baubigny, Pierre Lalanne, Simon de Beco, Mathieu Coppey, Catherine Villard, Vincent Humblot, Emmanuelle Marie, Christophe Tribet

Spontaneous adsorption of poly(lysine)-g-poly(ethyleneglycol) comb-like copolymers (PLL-g-PEG) is a versatile mean to coat substrates with polymer layers that resist cell adhesion. We prepared redox cleavable PLL-g-PEG to switch adhesion on demand. Redox sensitivity was obtained by introducing…

Surface Chirality of Gly-Pro Dipeptide Adsorbed on a Cu(110) Surface

Hervé Cruguel, Christophe Méthivier, Claire-Marie Pradier, Vincent Humblot

The adsorption of chiral Gly-Pro dipeptide on Cu(110) has been characterized by combining in situ polarization modulation infrared reflection absorption spectroscopy (PM-RAIRS) and X-ray photoelectron spectroscopy (XPS). The chemical state of the dipeptide, and its anchoring points and adsorption…

Enzymatic Approach in Calcium Phosphate Biomineralization: A Contribution to Reconcile the Physicochemical with the Physiological View

Clément Guibert, Jessem Landoulsi

Biomineralization is the process by which organisms produce hard inorganic matter from soft tissues with outstanding control of mineral deposition in time and space. For this purpose, organisms deploy a sophisticated “toolkit” that has resulted in significant evolutionary innovations, for which…

Steam reforming of alpha-methylnaphthalene as a model tar compound over olivine and olivine supported nickel

Rudy Michel, Agata Lamacz, Andrzej Krzton, Gérald Djéga-Mariadassou, Philippe Burg, Claire Courson, Rene Gruber

At high temperature, biomass steam gasification generates tars and more particularly Polycyclic Aromatic Hydrocarbons (PAHs). To assess the ability of olivine-based catalyst to eliminate the tars by steam reforming, alpha-methylnaphthalene (MNP) was chosen as model compound. The Ni/olivine has…

Kinetic Model of Energy Transfer Processes Between Low-Coordinated Ions on MgO by Photoluminescence Decay Measurements

Céline Chizallet, Guylène Costentin, Jean-Marc Krafft, Hélène Pernot, Michel Che

Photoluminescence decay studies of emitting species on MgO nanocubes at room temperature provide evidence of three sur- face species characterized by an excitation and emission wave- length couple {l exc ;l em }.Species A corresponds to {l exc =240 nm; l em =380 nm},whereas the couple {l exc =280…
