Modification des propriétés de surface d'un polypropylène en vue de l'immobilisation de biomolécules aux propriétés antibactériennes, Modification of surface properties of polypropylene for immobilization of antibacterial biomolecules

Simon Léoment

Depuis la nuit des temps, l’homme a fabriqué et utilisé des produits cosmétiques. De la Gaule à l’Egypte, en passant par l’Empire Romain et la Grèce antique, les hommes et les femmes s’appliquaient sur le visage et le corps des produits naturels ou transformés (huiles, poudres, mixtures, laits, etc…, Since the dawn of time, man has manufactured and used cosmetic products. From Gaul to Egypt, passing through the Roman Empire and ancient Greece, men and women applied to the face and body of natural or processed products (oils, powders, mixtures, milks, etc.) in order to embellish oneself, to heal…

Using planktonic microorganisms to supply the unpurified multi-copper oxidases laccase and copper efflux oxidases at a biofuel cell cathode

Sabine Sane, Katrin Richter, Stefanie Rubenwolf, Nina Joan Matschke, Claude Jolival, Catherine Madzak, Roland Zengerle, Johannes Gescher, Sven Kerzenmacher

The feasibility to apply crude culture supernatants that contain the multicopper oxidases laccase or copper efflux oxidase (CueO) as oxygen reducing catalysts in a biofuel cell cathode is shown. As enzyme-secreting recombinant planktonic microorganisms, the yeast Yarrowia lipolytica and the…

Phase selective synthesis of nickel silicide nanocrystals in molten salts for electrocatalysis of the oxygen evolution reaction

Ram Kumar, Mounib Bahri, Yang Song, Francisco Gonell, Cyril Thomas, Ovidiu Ersen, Clément Sanchez, Christel Laberty-Robert, David Portehault

We report phase selective synthesis of intermetallic nickel silicide nanocrystals in inorganic molten salts. NiSi and Ni2Si nanocrystals are obtained by reacting a nickel (II) salt and sodium silicide Na4Si4 in the molten LiI-KI inorganic eutectic salt mixture. We report that nickel silicide…

A Rotaxane Scaffold Bearing Multiple Redox Centers: Synthesis, Surface Modification and Electrochemical Properties

Marie Steffenhagen, Alina Latus, Thi Minh Nguyet Trinh, Iwona Nierengarten, Ivan T. Lucas, Suzanne Joiret, Jessem Landoulsi, Béatrice Delavaux-Nicot, Jean-François Nierengarten, Emmanuel Maisonhaute

A rotaxane scaffold incorporating two dithiolane anchoring units for the modification of gold surfaces has been functionalized with multiple copies of a redox unit, namely ferrocene. Surface modification has been first assessed at the single molecule level by atomic force microscopy (AFM) and…

Controlling the Nanocontact Nature and the Mechanical Properties of a Silica Nanoparticle Assembly

J. Avice, C. Boscher, G. Vaudel, G. Brotons, V. Juvé, M. Edely, C. Methivier, Vitali Goussev, P. Belleville, H. Piombini, P. Ruello

Elaborating advanced nanomaterials based on the assembly of nanoparticles (NPs) is a versatile route for targeting and tuning a wide variety of properties like optical, magnetic, and electrical properties or sensing. This route usually employs a so-called soft chemistry which has the advantage of…

Polarizable QM/Classical Approaches for the Modeling of Solvation Effects on UV–Vis and Fluorescence Spectra: An Integrated Strategy

Daniele Loco, Natalia Gelfand, Sandro Jurinovich, Stefano Protti, Alberto Mezzetti, Benedetta Mennucci

Hybrid methods combining quantum chemistry and classical models are largely used to describe solvent effects in absorption and emission processes of solvated chromophores. Here we compare three different formulations of these hybrid approaches, using a continuum, an atomistic, or a mixed…

Comparing the mechanism of urea and ammonia electro-oxidation reactions on Ni-based catalysts

Sophia Akkari, Carlos M Sánchez-Sánchez, Vincent Vivier

In recent decades, special attention has been paid to the electrochemical oxidation of organic compounds, such as urea (H2NCONH2) from urine, in order to avoid their natural degradation into detrimental products, as well as to produce energy by using fuel cells [1]. Its presence in sewages and its…

Potential Role of Inorganic Confined Environments in Prebiotic Phosphorylation

Avinash Vicholous Dass, Maguy Jaber, André Brack, Frédéric Foucher, Terence P Kee, Thomas Georgelin, Frances Westall

A concise outlook on the potential role of confinement in phosphorylation and phosphate condensation pertaining to prebiotic chemistry is presented. Inorganic confinement is a relatively uncharted domain in studies concerning prebiotic chemistry, and even more so in terms of experimentation.…
