Bioactive peptides grafted silicone dressings: A simple and specific method

Coline Pinese, Said Jebors, Pierre-Emmanuel Stoebner, Vincent Humblot, Pascal Verdié, Léa Causse, Xavier Garric, Hubert Taillades, Jean Martinez, Ahmad Mehdi, Gilles Subra

The need for bioactive dressings increases with the population aging and the prevalence of chronic diseases. In contrast, there are very few dressings on the market which are designed to display a chosen bioactivity. In this context, we investigated the surface-functionalization of silicone wound…

Nanosized Layered TOT Magnesium-Silicates: Equilibrium Morphologies and Surface Speciation, a Computational and Experimental Study

Hervé Toulhoat, Longfei Lin, Dalil Brouri, Jean-Marc Krafft, Yannick Millot, Guillaume Laugel, Hélène Lauron-Pernot

The morphology, surface speciation, NMR, and IR spectroscopic properties of nanosized layered magnesium silicate isostructural to talc at equilibrium in an aqueous environment were computed from first principles. The theoretical predictions were successfully compared with experimental results…

Nanostructured Nickel Aluminate as a Key Intermediate for the Production of Highly Dispersed and Stable Nickel Nanoparticles Supported within Mesoporous Alumina for Dry Reforming of Methane

Leila Karam, Julien Reboul, Nissrine El Hassan, Jaysen Nelayah, Pascale Massiani

Two routes of preparation of mesoporous Ni-alumina materials favoring the intermediate formation of nanostructured nickel-aluminate are presented. The first one involves an aluminum containing MOF precursor used as sacrificial template to deposit nickel while the second is based on a one-pot…

Electrodeposition and soft oxidation of nickel‑iron hydroxides: An efficient two-step approach for the synthesis of highly active and stable iron-rich NiFe-LDHs with controlled Ni/Fe composition for oxygen evolution reaction

Yakoub Smati, Divino Salvador Ramírez-Rico, Antoine Miche, Jean-Marc Krafft, David Montero, Mireille Turmine, Vincent Vivier, Julien Reboul, Juliette Blanchard

Nickel‑iron layered double hydroxides (NiFe-LDHs) are promising low-cost and active electrocatalysts for the alkaline oxygen evolution reaction (OER), yet conventional synthesis methods face two key limitations: (i) poor control over the Ni/Fe atomic ratio and (ii) difficulty in producing active,…

Oscillatory Behavior of Pd-Au Catalysts in Toluene Total Oxidation

Tarek Barakat, Joanna Rooke, Dayan Chlala, Renaud Cousin, Jean-François Lamonier, Jean-Marc Giraudon, Sandra Casale, Pascale Massiani, Bao-Lian Su, Stéphane Siffert

In this work, the activity of bimetallic Pd-Au doped hierarchically structured titania catalysts has been investigated in the total oxidation of toluene. In earlier works, doping titania with group Vb metal oxides ensured an increased catalytic performance in the elimination of VOC molecules. A…

Coupling morphological evolution and multiphase transport to Decipher degradation in PEM water electrolyzers

Youssef Kharchouf, Loïc Assaud, Mireille Turmine, Vincent Vivier

In this work, we present a multiphase numerical model for the corrosion degradation of proton exchange membrane water electrolyzers. The numerical framework comprises two main components, a geometry tracking component and a performance evaluation component. The geometry tracking is based on the…

Enzyme Immobilization on Silane-Modified Surface through Short Linkers: Fate of Interfacial Phases and Impact on Catalytic Activity

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

We investigated the mechanism of enzyme immobilization on silanized surfaces through coupling agents (cross-linkers) in order to understand the role of these molecules on interfacial processes and their effect on catalytic activity. To this end, we used a model multimeric enzyme (G6PDH) and several…
