Nano-engineered hierarchical porous silicas for enhanced catalytic efficiency in the liquid phase

Abdelali Zaki, M. Wastiaux, Sandra Casale, Alexandre Mussi, Jean-François Dhenin, Christine Lancelot, Jean-Philippe Dacquin, Pascal Granger

By tailoring the pore properties (size, morphology and orientation) of hierarchical catalysts, we show experimentally the importance of active phase accessibility on catalytic efficiency. This finding likely contributes to a better rationalisation of the structure sensitivity of the nitrite…

Design of plasmonic nanoparticles and their use for biotoxin immunosensing, Conception de nanoparticules plasmoniques et leur utilisation pour l'immunodétection d’une biotoxine

Lu Zhang

Staphylococcal enterotoxin A (SEA) produced by some Staphylococcus aureus strains is a major cause of food poising and especially represents the second cause of foodborne diseases in France. Plasmonic nanoparticles with unique optical properties are widely applied as transducers in biosensing…, L'entérotoxine A du staphylocoque (SEA) produite par certaines souches de Staphylococcus aureus est une cause majeure d'intoxication alimentaire et représente la deuxième cause de maladies d'origine alimentaire en France. Les nanoparticules (NPs) plasmoniques aux propriétés optiques…

Oxidation of laccase for improved cathode biofuel cells performances

Meihui Zheng, Sophie Griveau, Christine Dupont-Gillain, Michel J Genet, Claude Jolivalt

Graphite rods were modified by substituted aryldiazonium salts allowing subsequent laccase immobilisation and direct electron transfer at the cathode. Two covalent enzyme immobilisation methods were performed with carboxy and amino substituted grafted groups, either via the formation of an amide…

Erratum to: Surface functionalization by covalent immobilization of an innovative carvacrol derivative to avoid fungal biofilm formation

Aïcha Gharbi, Thibaut Legigan, Vincent Humblot, Sébastien Papot, Christine Imbert, Jean-Marc Berjeaud

Carvacrol, an aromatic terpenic compound, known to be antimicrobial was grafted onto gold surfaces via two strategies based on newly-synthesized cross-linkers involving either an ester bond which can be cleaved by microbial esterases, or a covalent ether link. Surface functionalizations were…

To be born is not enough: the key role of innovative start-ups

Alessandra Colombelli, Jackie Krafft, Marco Vivarelli

This paper investigates the reasons why entry per se is not necessarily good and the evidence showing that innovative start-ups survive longer than their non-innovative counterparts. In this framework, our own empirical analysis shows that greater survival is achieved when start-ups engage…

“Nanocasting”: using SBA-15 silicas as hard templates to obtain monodispersed superparamagnetic gamma-Fe2O3 nanoparticles

Anne Davidson, Emilie Delahaye, Virginie Escax, Nissrine El Hassan, Renata Aquino, Vincent Dupuis, Regine Perzynski, Yuri Raikher

This work describes the use of mesoporous SBA-15 silicas as hard templates, for the size-controlled synthesis of oxides nanoparticles, the pores acting as nanoscale reactors. This fundamental work is mainly aimed at understanding unresolved issues concerning the occurrence and size dependence of…

Chemically and Physically Pretreated Straw in Moderate Conditions: Poor Correlation between Biogas Production and Commonly Used Biomass Characterization

Shruthi Meenakshisundaram, Vincenzo Calcagno, Claire Ceballos, Antoine Fayeulle, Estelle Léonard, Virginie Herledan, Jean-Marc Krafft, Yannick Millot, Xiaojun Liu, Claude Jolivalt, André Pauss

Straw is a substantial agricultural by-product for biogas production. Hydrolysis of straw is found to be a rate-limiting step during its anaerobic digestion and could be enhanced by pretreatment. In this paper, the effect of various combinations of particle size reduction, autoclaving, and low-…

Factors impacting the aggregation/agglomeration and photocatalytic activity of highly crystalline spheroid- and rod-shaped TiO 2 nanoparticles in aqueous solutions

Thomas Degabriel, Elodie Colaço, Rute F Domingos, Karim El Kirat, Dalil Brouri, Sandra Casale, Jessem Landoulsi, Jolanda Spadavecchia

We investigate the characteristics, fate and photocatalytic activity of spheroid- and rod-shaped TiO2 nano-crystals in aqueous solutions to better understand their behaviour in media of biological and environmental interest. For this purpose, the potential of a solvothermal method in synthesizing…

Enzyme-assisted mineralization of calcium phosphate: exploring confinement for the design of highly crystalline nano-objects

E. Colaço, D. Lefèvre, E. Maisonhaute, D. Brouri, C. Guibert, C. Dupont-Gillain, Karim El Kirat, S. Demoustier-Champagne, J. Landoulsi

In hard tissues of vertebrates, calcium phosphate (CaP) biomineralization is a fascinating process that combines specific physicochemical and biochemical reactions, resulting in the formation of extracellular matrices with elegant nanoarchitectures. Although several “biomimetic” strategies have…
