Clicked BODIPY‐Fullerene‐Peptide Assemblies: Studies of Electron Transfer Processes in Self‐Assembled Monolayers on Gold Surfaces

Jad Rabah, Houssein Nasrallah, Karen Wright, Isabelle Gérard, Hélène Fensterbank, Thi Tuyet Van Bui, Jérôme Marrot, Thu-Trang Tran, Anam Fatima, Minh-Huong Ha-Thi, Rachel Méallet, Gotard Burdzinski, Gilles Clavier, Souhir Boujday, Hubert Cachet, Catherine Debiemme-Chouvy, Emmanuel Maisonhaute, Anne Vallée, Emmanuel Allard

Two BODIPY‐C60‐peptide assemblies were synthesized by CuAAC reactions of BODIPY‐C60 dyads and a helical peptide functionalized with a terminal alkyne group and an azide group, respectively. The helical peptide within these assemblies was functionalized at its other end by a disulfide group,…

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…

A simple way to graft a bioactive polymer – Polystyrene sodium sulfonate on silicone surfaces

Mylan Lam, Vivien Moris, Vincent Humblot, Veronique Migonney, Céline Falentin-Daudre

Silicone-based materials are largely used in plenty of fields, especially in the biomedical field as implantable devices for surgery purposes. However, due to recent issues, the safety of the material has been reconsidered. In this work, we aim to graft a bioactive polymer on silicone breast…

NOx-TPD as a Tool to Estimate the Accessible Zirconia Surface of ZrO2-Containing Materials

Hiu Ying Law, Juliette Blanchard, Xavier Carrier, Cyril Thomas

NOx adsorption-desorption experiments were carried out on a series of W-free and W-containing ZrO2 samples. To the best of our knowledge, this study establishes for the first time NOx-TPD (temperature-programmed desorption of NOx) as a reliable method to estimate the accessible ZrO2 surface of…

Tough thiourethane thermoplastics for fused filament fabrication

Gregory Ellson, Xavier Carrier, Jamie Walton, Samsuddin Faisal Mahmood, Kejia Yang, Joshua Salazar, Walter Voit

Fused filament fabrication (FFF) is the most common form of additive manufacturing. Most FFF materials are variants of commercially available engineering plastics. Their performance when printed can widely vary, thus there is an increasing volume of research on alternative materials with thermal…

Oxidation and Surface Segregation Behavior of a Pt–Pd–Rh Alloy Catalyst

Paul A. J. Bagot, Karen Kruska, Daniel Haley, Xavier Carrier, Eric Marceau, Michael. P. Moody, George D. W. Smith

Platinum gauze catalysts are used extensively in the production of nitricacid from ammonia, where they are subject to harsh operating conditions combiningelevated temperatures and oxidizing environments. These cause significant loss of metalspecies as volatile oxides. How different metallic species…

Optimization of Synthesis Conditions of Ni/SBA-15 Catalysts: Confined Nanoparticles and Improved Stability in Dry Reforming of Methane

Nissrine El Hassan, Marie-Nour Kaydouh, Nissrine El, Anne Davidson, Pascale Massiani

Despite its economic and environmental advantages, the dry reforming of methane using supported Ni-based catalysts remains challenging due to problems of metal particle sintering and carbon deposition, which lead to loss in catalytic activity. In this study, different silica supports, containing 5…
