Tuning the load in gold and magnetic nanoparticles in nanogels through their design for enhanced dual magneto-photo-thermia

Esther Cazares-Cortes, Claire Wilhelm, Jose Efrain Perez, Ana Espinosa, Sandra Casale, Aude Michel, Ali Abou-Hassan, Christine Ménager

We describe a novel synthesis allowing to enhance the load in magnetic nanoparticles and gold nanorods in nanogels. Two different structures, simple cores and core-shells were synthesized and their heating properties upon alternating magnetic field or laser exposure are compared. Remarkably, the…

Light-induced infrared difference spectroscopy on three different forms of orange carotenoid protein: focus on carotenoid vibrations

Silvia Leccese, Adjélé Wilson, Diana Kirilovsky, Riccardo Spezia, Claude Jolivalt, Alberto Mezzetti

Orange carotenoid protein (OCP) is a photoactive carotenoprotein involved in photoprotection of cyanobacteria, which uses a keto-catorenoid as a chromophore. When it absorbs blue-green light, it converts from an inactive OCPO orange form to an activated OCPR red form, the latter being able to bind…

Nanosized Layered TOT Magnesium-Silicates: Equilibrium Morphologies and Surface Speciation, a Computational and Experimental Study

Hervé Toulhoat, Longfei Lin, Dalil Brouri, Jean-Marc Krafft, Yannick Millot, Guillaume Laugel, Hélène Lauron-Pernot

The morphology, surface speciation, NMR, and IR spectroscopic properties of nanosized layered magnesium silicate isostructural to talc at equilibrium in an aqueous environment were computed from first principles. The theoretical predictions were successfully compared with experimental results…

Impact of Collagen Crosslinking on Dislocated Human Shoulder Capsules—Effect on Structural and Mechanical Properties

Pauline Cornette, Ilhem Jaabar, Vincent Dupres, Jean-David Werthel, Francis Berenbaum, Xavier Houard, Jessem Landoulsi, Geoffroy Nourissat

Classical treatments of shoulder instability are associated with recurrence. To determine whether the modification of the capsule properties may be an alternative procedure, the effect of crosslinking treatment on the structure and mechanical properties of diseased human shoulder capsules was…

Halide-free CO 2 cycloaddition onto styrene oxide catalysed by first row transition-metal derivatives of polyoxotungstates

Jingjing Ren, Franck Launay, Richard Villanneau, Anna Proust

Quaternary ammonium salts of metal derivatives of polyoxometalates [XW11O39M(H2O)]n- (X = P, Si; M = Cr, Mn, Co, Ni, Zn) were successfully tested instead of quaternary ammonium halides as catalysts in the cycloaddition of CO2 to styrene oxide. Remarkably, they gave very satisfactory yields of…

Laccase production from sucrose by recombinant Yarrowia lipolytica and its application to decolorization of environmental pollutant dyes

Farshad Darvishi, Marzieh Moradi, Claude Jolivalt, Catherine Madzak

Laccases are used in decolorization and biodegradation of synthetic dyes, bioremediation of industrial waste-waters and delignification of lignocellulosic compounds. The aims of the present study were the optimization of a recombinant laccase production in Yarrowia lipolytica yeast using sucrose as…

Vanadium-Substituted Phosphomolybdic Acids for the Aerobic Cleavage of Lignin Models-Mechanistic Aspect and Extension to Lignin

Louay Al-Hussaini, Franck Launay, Elena Galvez

This work deals with the aerobic oxidative cleavage of CC and CO bonds catalyzed by the Keggin-type phosphovanadomolybdic acid (H 6 [PMo 9 V 3 O 40 ], noted H 6 PV 3). The latter was synthesized by an adapted hydrothermal procedure classically used for lower vanadium content and was tested as a…
