  • Multispecies Biofilm Development of Marine Bacteria Implies Complex Relationships Through Competition and Synergy and Modification of Matrix Components
    16 April 2019

    Guillonneau, R.; Baraquet, C.; Bazire, A.; Molmeret, M. Front. Microbiol. 2018, 9. https://doi.org/10.3389/fmicb.2018.01960
    Abstract : Microbial communities composition is largely shaped by interspecies competition or cooperation in most environments. Ecosystems are made of various dynamic microhabitats where microbial communities interact with each other establishing metabolically interdependent relationships. Very limited information is available on multispecies biofilms and their (…)

  • Screening of bromotyramine analogues as antifouling compounds against marine bacteria
    30 May 2017

    Andjouh, S.; Blache, Y. Screening of Bromotyramine Analogues as Antifouling Compounds against Marine Bacteria. Biofouling 2016, 32 (8), 871–881 Abstract :
    Rapid and efficient synthesis of 23 analogues inspired by bromotyramine derivatives, marine natural products, by means of CuSO4-catalysed [3+2] alkyne–azide cycloaddition is described. The final target was then assayed for anti-biofilm activity against three Gram-negative marine bacteria, Pseudoalteromonas ulvae (TC14), (…)

  • Multiscale investigation of the effect of sizing chemistry on the adhesion and interfacial properties of glass fiber-reinforced epoxy composites
    27 September 2022

    S. Assengone Otogo Be, A. Fahs, L. Belec, S. Belkessam, G. Louarn, J.-F. Chailan, Polymer Composites, 2022, 1-13. https://doi.org/10.1002/pc.27064
    Abstract
    The objective of the present work is to understand how the main constituents of sizing modify the interfacial strength, the mechanical properties of epoxy composites as well as their durability. In this study, two model interphases between E-glass fibers and epoxy resin were designed and studied in terms of adhesion and mechanical (…)

  • An ABAQUS™ plug-in for the geometry generation of Representative Volume Elements with randomly distributed fibers and interphases
    31 January 2019

    [Riaño, L.; Joliff, Y. An Abaqus™ Plug-in for the Geometry Generation of Representative Volume Elements with Randomly Distributed Fibers and Interphases. Composite Structures 2019, 209, 644–651. >https://doi.org/10.1016/j.compstruct.2018.10.096]
    Abstract : This paper proposes a plug-in called RVE for composites for the commercial software ABAQUS™. This tool generates 2D as well as 3D multi-fiber microstructure geometries for unidirectional composites with random distributions. Its (…)

  • Comparative effects of humid tropical weathering and artificial ageing on a model composite properties from nano- to macro-scale
    2 November 2015, by webmaster

    Belec, L.; Nguyen, T. H.; Nguyen, D. L.; Chailan, J. F. Composites Part A: Applied Science and Manufacturing 2015, 68, 235–241
    Abstract :
    The effects of humid tropical conditions and artificial ageing tests on a UD glass-fibre/epoxy composite are compared at different scales. A modified network of 500 nm width around each fibre is identified by AFM force measurements. The evolution of this interphase is correlated to the composite embrittlement observed in transverse bending tests (…)

  • Hydrolyzable Additive-Based Silicone Elastomers: A New Approach for Antifouling Coatings
    5 March 2020

    Gevaux, L.; Lejars, M.; Margaillan, A.; Briand, J.-F.; Bunet, R.; Bressy, C. Hydrolyzable Additive-Based Silicone Elastomers: A New Approach for Antifouling Coatings. Polymers 2019, 11 (2), 305
    Abstract : Fouling Release Coatings are marine antifouling coatings based on silicone elastomers. Contrary to commonly used biocide-based antifouling coatings, they do not release biocides into the marine environment, however, they suffer from poor antifouling efficacy during idle periods. To (…)
