Dual Thermo- and pH-Responsive N -Cyanomethylacrylamide-Based Nano-Objects Prepared by RAFT-Mediated Aqueous Polymerization-Induced Self-Assembly

Nicolas Audureau, Fanny Coumes, Jean-Michel Guigner, Clément Guibert, François Stoffelbach, Jutta Rieger

We report the straightforward synthesis of dual stimuli-responsive nano-objects using a RAFT-mediated polymerization-induced self-assembly (PISA) process in water. The key to complex and tunable responsiveness was the copolymerization of N-cyanomethylacrylamide, providing UCST-type polymers, with a…

Light-adapted charge-separated state of photosystem II: structural and functional dynamics of the closed reaction center

Melinda Magyar, Alberto Mezzetti, Parveen Akhtar, Qingjun Zhu, Yanan Xiao, Guangye Han, Stefano Santabarbara, Jian-Ren Shen, Petar Lambrev, Győző Garab, Gábor Sipka

Photosystem II (PSII) uses solar energy to oxidize water and delivers electrons for life on Earth. The photochemical reaction center of PSII is known to possess two stationary states. In the open state (PSIIO), the absorption of a single photon triggers electron-transfer steps, which convert PSII…

Deciphering pathological remodelling of the human cartilage extracellular matrix in osteoarthritis at the supramolecular level

Ilhem Lilia Jaabar, Pauline Cornette, Antoine Miche, Kristell Wanherdrick, Vincent Dupres, François-Paul Ehkirch, Adeline Cambon Binder, Francis Berenbaum, Xavier Houard, Jessem Landoulsi

Osteoarthritis induces a combination of chemical, structural and nanomechanical changes to collagen fibrils and aggrecan aggregates, the main building blocks of cartilage ECM, that may be mimicked by specific enzymatic reactions.

Progress on electrochemical and photoelectrochemical urea and ammonia conversion from urine for sustainable wastewater treatment

Sophia Akkari, Carlos M. Sánchez-Sánchez, Guillaume Hopsort, Karine Groenen Serrano, Karine Loubière, Théodore Tzedakis, Raihana Benyahia, Lamia Rebiai, Stéphane Bastide, Christine Cachet-Vivier, Vincent Vivier, Melissa Lopez-Viveros, Sam Azimi

The valorization of urine through the electro-oxidation of urea offers a promising alternative for industrial wastewater treatment plants. This operation, implemented at room temperature, allows, in addition to the depolluting action, the generation of hydrogen at the cathode. Using inexpensive…

Catalytic activity and thermostability of enzymes immobilized on silanized surface: Influence of the crosslinking agent

Nesrine Aissaoui, Jessem Landoulsi, Latifa Bergaoui, Souhir Boujday, Jean-François Lambert

In this work, we investigate the influence of crosslinkers on the operational and heat stability of immobilized enzymes on a silanized silicon surface. To this end, glucose-6-phosphate dehydrogenase (G6PDH), a model multimeric enzyme, was attached through bifunctional crosslinkers able to bind…

Hydrodesulfurization of 4,6-Dimethyldibenzothiophene and the Diesel Oil Fraction on NiMo Catalysts Supported over Proton-Exchanged AlMCM-41 and TiMCM-41 Extrudates

Karolina Jaroszewska, Marek Lewandowski, Kinga Góra-Marek, Jolanta Grzechowiak, Gérald Djéga-Mariadassou

NiMo catalysts supported on mesoporous MCM-41 type materials shaped with binder were tested for activity in the hydrodesulfurization of 4,6-dimethyldibenzothiophene (4,6-DMDBT) and the diesel fuel fraction (0.92 wt% of sulfur). The aim of the investigation was to evaluate the effect of ion exchange…

Electrochemical deposition of ZnO thin films in aprotic ionic liquids: Effect of the cationic alkyl-chain-length

Rita Khalil, Mirella Azar, Ibrahim Bou Malham, Mireille Turmine, Vincent Vivier

Zinc oxide (ZnO) is a semiconductor with various physicochemical properties allowing its use in a wide range of technological applications. The aim of this work is to study nanocrystalline ZnO thin-film deposited using zinc salt which is dissolved in pure ionic liquids (ILs). The latter play a dual…
