Impact of nontronite on the evolution of organic molecules at the surface of Mars

Patrice Coll, Olivier Poch, Maguy Jaber, Jean-François Lambert, Thomas Georgelin, Cyril Szopa, Fabien Stalport

Several evidences suggest that early Mars offered favorable conditions for long-term sustaining water. As a consequence, we can assume that in those days, endogenous chemical processes, or even primitive life, may have produced organic matter on Mars. Moreover, exogenous delivery from small bodies…

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…

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…

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-…

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…

Silk foams with metallic nanoparticles as scaffolds for soft tissue regeneration

Claire de Lartigue, Cristina Belda Marín, Vincent Fitzpatrick, Antonella Esposito, Sandra Casale, Jessem Landoulsi, Erwan Guénin, Christophe Egles

Tissue regeneration can be achieved by providing endogenous cells with a biomaterial scaffold that supports their adhesion and proliferation, as well as the synthesis and deposition of an extracellular matrix (ECM). In this work, silk fibroin protein foams were formed by lyophilization to generate…
