EIS investigations of the oxygen reduction reaction at the cathode of an enzymatic biofuel cell

Achraft Blout, Florence Billon, Hubert Perrot, Claude Jolivalt, Alain Pailleret

Enzymatic biofuel cells (EBCs) have been extensively studied over the last ten years in view of their application as implantable devices [1,2] as they have been shown indeed to reach the power required for small electronic devices. In EBCs, redox reactions occurring at the cathode and the anode are…

Improvement of the Catalytic Performances of SBA‐15 in the Formylation of Aniline upon the Introduction of Template‐Free Nano‐Faujasite in Its Synthesis Gel

Karima Baghdad, Mohammed Abdelkrim Hasnaoui, Franck Launay

Faujasite nanoparticles with average size of 10–40 nm were obtained without any organic structure directing agents (Green synthesis), then used as precursors for the synthesis of NaY/SBA-15 composites. Two types of composites were obtained with meso/micro porosity (C1 and C2).The inorganic salt,…

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…

CO 2 methanation over LDH derived NiMgAl and NiMgAlFe oxides: Improving activity at lower temperatures via an ultrasound-assisted preparation

Michel Obeid, Christophe Poupin, Madona Labaki, Samer Aouad, Sharad Gupta, Haingomalala Lucette Tidahy, Aida Younis, Ferdaous Ben Romdhane, Eric Gaigneaux, Josefine Schnee, Edmond Abi-Aad, François Delattre

Within the idea to catalyze CO 2 methanation NiMgAl and NiMgAlFe oxides were synthesized by the layered double hydroxide route using co-precipitation and ultrasound-assisted co-precipitation. MgAl and MgAlFe oxides-supported Ni materials prepared by the impregnation method were used as references.…

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…

Revealing the Interplay between Adsorbed Molecular Layers and Gold Nanoparticles by Linear and Nonlinear Optical Properties

Laetitia Dalstein, Maroua Ben Haddada, Grégory Barbillon, Christophe Humbert, Abderrahmane Tadjeddine, Souhir Boujday, Bertrand Busson

Gold nanoparticles (AuNPs) chemically grafted on substrates are widely used as sensors due to their plasmonic properties. The efficiency and robustness of such sensors strongly depend on the molecular sublayer structure, which influences the distribution of AuNPs, and therefore the plasmonic…
