Optimization and Antibacterial Response of N-Halamine Coatings Based on Polydopamine

Nadia Nazi, Adeline Marguier, Catherine Debiemme-Chouvy, Vincent Humblot

RessouDue to the ability of microorganisms to first adhere to a material surface and then to lead to the formation of a biofilm, it is essential to develop surfaces that have antimicrobial properties. It is well known that N-halamine coatings allow us to prevent or minimize such phenomena. In the…

A Graftable Quaternary Ammonium Biocidal Polymer Reduces Biofilm Formation and Ensures Biocompatibility of Medical Devices

Houssam Bouloussa, Azzam Saleh‐mghir, Claire Valotteau, Chahrazad Cherifi, Narjès Hafsia, Martine Cohen‐solal, Charles Court, Anne‐claude Crémieux, Vincent Humblot

A quaternized polyvinylpyridine (Q‐PVP) polymer methanolic solution synthesized in a single step is used to covalently graft titanium surfaces. Q‐PVP is quaternized with varying N+/N ratios. 1 cm2 pure titanium plates are polished and activated. Treated samples are grafted by spin coating or dip‐…

Modelling of a Lean NOx-Trap system with NO/NO2 differentiation and sulfur poisoning

Alexis Manigrasso, Pierre Darcy, Patrick da Costa

One of the challenges in the automotive industry is to develop new vehicles and new technologies with minimal costs. In this context, modeling becomes an important tool for the design of future technologies by reducing the number of tests needed to develop a new exhaust system. With the emergence…

Surface‐Dependent Activation of Model α‐Al2O3‐Supported P‐Doped Hydrotreating Catalysts Prepared by Spin Coating

Ricardo Garcia de Castro, Jérémy Bertrand, Baptiste Rigaud, Elodie Devers, Mathieu Digne, Anne‐félicie Lamic-Humblot, Gerhard Pirngruber, Xavier Carrier

Requirements for improved catalytic formulations is continuously driving research in hydrotreating (HDT) catalysis for biomass upgrading and heteroatom removal for cleaner fuels. The present work proposes a surface-science approach for the understanding of the genesis of the active (sulfide) phase…

Electrochemical and spectroscopic evidences of corrosion inhibition of bronze by a triazole derivative

Ahmed Dermaj, Najat Hajjaji, Suzanne Joiret, Kamal Rahmouni, Abdellah Srhiri, Hisasi Takenouti, Vincent Vivier

The electrochemical behavior of the bronze (Cu–8Sn in wt%) was investigated in 3% NaCl aqueous solution, in presence and in absence of a corrosion inhibitor, the 3-phenyl-1,2,4-triazole-5-thione (PTS). The inhibiting effect of the PTS was evidenced for concentrations higher than 1 mM for the…

Modifying protein adsorption by layers of glutathione pre-adsorbed on Au(111).

Anne Vallée, Vincent Humblot, Christophe Méthivier, Paul Dumas, Claire-Marie Pradier

Molecular interaction with metal surfaces raises fundamental questions regarding their binding tendency, their dispersion on the surface, as well as their conformation which may change their biological properties; addressing these questions, and being able to tune protein interactions, is of…

Identification and Location of Iron Species in Fe/SBA-15 Catalysts: Interest for Catalytic Fenton Reactions

Cécile Cornu, Jean-Luc Bonardet, Sandra Casale, Anne Davidson, Sebastien Abramson, Gilles André, Florence Porchet, Ivana Grcic, Vesna Tomasic, Dinko Vujevic

We have used a single SBA-15 silica batch (mesopore diameter of 7.1 nm) and the two-solvent impregnation technique with either pentane or cyclohexane to prepare model samples in which an initial aqueous solution of salt precursor (iron nitrate or iron chloride) is deposited mainly inside silica…

How does CO capture process on microporous NaY zeolites? A FTIR and DFT combined study

Olivier Cairon, Hazar Guesmi

Reliable experimental IR and theoretical approaches, both investigating CO adsorption on NaY faujasites, are supporting that CO capture occurs through the completion of the vacant coordination of Na+ cations located in the accessible SII sites. As a result, carbonyl adsorbed species are formed by…

New ammonium surfactant-stabilized rhodium(0) colloidal suspensions: influence of novel counter-anions on physico-chemical and catalytic properties.

Elodie Bile Guyonnet, Rita Sassine, Audrey Denicourt-Nowicki, Franck Launay, Alain Roucoux

Novel anionic species, such as hydrogen carbonate (HCO(3)(−)), fluoride (F(−)), triflate (CF(3)SO(3)(−)), tetrafluoroborate (BF(4)(−)) and chloride (Cl(−)) were investigated as new partners of water soluble N,N-dimethyl-N-cetyl-N-(2-hydroxyethyl) ammonium salts, used as a protective agent of…
