Palladium Nanowires Synthesized in Hexagonal Mesophases: Application in Ethanol Electrooxidation

Faygal Ksar, Geetarani Surendran, Laurence Ramos, Bineta Keita, Louis Nadjo, Eric Prouzet, Patricia Beaunier, Agnes Hagege, Fabrice Audonnet, Hynd Remita

Palladium nanowires (of length a few tens of nanometers) are synthesized in a hexagonal mesophase formed by a quaternary system (Pd-doped water, surfactant, cosurfactant, and oil) by electron beam irradiation. The mesophases can be doped by high concentrations of palladium (0.1 M) without any…

A New Antibacterial N -Halamine Coating Based on Polydopamine

Nadia Nazi, Vincent Humblot, Catherine Debiemme

To prevent the formation of biofilms on material surfaces, the latter must have antibacterial properties. The aim of this study is to investigate the synthesis and the antibacterial effect of a new N-halamine coating based on polydopamine (PDA). The benefits of this coating are multiple, notably…

Catalytic Pyrolysis of Plastics over Maghemite-Impregnated Mesocellular Foam using Induction Heating

Luing Wong Syie, Sabino Armenise, B. Nyakuma Bemgba, Soon Ng Pang, Hau Lee Chia, Anna Bogush, Franck Launay, Evgeny Rebrov, Marta Munoz

Pyrolysis is a key technology that converts unrecyclable end-of-life plastics into value-added products. Nevertheless, the high energy consumption during plastic pyrolysis limits the economic feasibility of a scaled-up process. Development of an energy-efficient plastic pyrolysis process is…

Boronic species as promising inhibitors of the Staphylococcus aureus NorA efflux pump: Study of 6-substituted pyridine-3-boronic acid derivatives

Fanny Fontaine, Arnaud Héquet, Anne-Sophie Voisin-Chiret, Alexandre Bouillon, Aurélien Lesnard, Thierry Cresteil, Claude Jolivalt, Sylvain Rault

In response to the extensive use of antibiotics, bacteria have evolved numerous mechanisms of defense against antimicrobial agents. Among them, extrusion of the antimicrobial agents outside the bacterial cell through efflux pumps is a major cause of concern. At first limited to one or few…

Dégradation chimique et mécanique de l'alumine en phase aqueuse : mécanisme et inhibition en conditions ambiantes et hydrothermales, Chemical and mechanical degradation of alumina in aqueous phase : mechanism and inhibition in ambient and hydrothermal conditions

Jane Abi Aad

L'alumine, utilisée comme support de catalyseurs pour la réaction de Fischer-Tropsch ou pour la conversion de la biomasse, se transforme partiellement en présence d'eau en phases (oxy)hydroxydes à l'origine de fines qui posent problème dans la mise en ¿uvre de procédés en réacteurs…, Alumina, used as a catalyst support for the Fischer-Tropsch reaction or for the conversion of biomass, partially transforms in presence of water into (oxy)hydroxides phases. The formation of the latter leads to the production of fine particles that may cause plugging problems in the implementation…

Orange Carotenoid Protein in Mesoporous Silica: A New System towards the Development of Colorimetric and Fluorescent Sensors for pH and Temperature

Silvia Leccese, Andrea Calcinoni, Adjélé Wilson, Diana Kirilovsky, Donatella Carbonera, Thomas Onfroy, Claude Jolivalt, Alberto Mezzetti

Orange carotenoid protein (OCP) is a photochromic carotenoprotein involved in the photoprotection of cyanobacteria. It is activated by blue-green light to a red form OCPR capable of dissipating the excess of energy of the cyanobacterial photosynthetic light-harvesting systems. Activation to OCPR…

Design of Advanced Functional Materials Using Nanoporous Single‐Site Photocatalysts

Kohsuke Mori, Xufang Qian, Yasutaka Kuwahara, Yu Horiuchi, Takashi Kamegawa, Yixin Zhao, Catherine Louis, Hiromi Yamashita

Nanoporous silica solids can offer opportunities for hosting photocatalytic components such as various tetra-coordinated transition metal ions to form systems referred to as “single-site photocatalysts”. Under UV/visible-light irradiation, they form charge transfer excited states, which exhibit a…
