Analyse descriptive quantitative et modélisation numérique de la microstructure de composite SMC moule par un procédé de compression industriel

Laura Oter Carbonell2018-12-12theses.fr (ABES)

Compression moulding of SMC is a processing technology for reactive polymers reinforced with chopped fibres in a composite material. It involves both the flow and deformation of the raw material to transform it into its final shape, thanks of heat and pressure applied to a matched metal moulds mounted under press. The…

Nanodefects Formed under Electron Irradiation in Aluminum

Camille Jacquelin2018-12-12theses.fr (ABES)

Sous irradiation, les flux de particules (neutrons, ions, électrons) créent des défauts ponctuels (lacunes et interstitiels) qui génèrent des défauts étendus (boucles de dislocation, cavités) responsables de la fragilisation des matériaux. L'aluminium est un matériau de faible masse et de faible énergie seuil de dépla…

Study of the adhesion phenomenon in the Pacific oyster larvae Crassostrea gigas at the pediveliger stage.

Valentin Foulon2018-12-12theses.fr (ABES)

Les huîtres présentent un cycle de vie en deux phases : les larves pélagiques s’adhérent avant de se métamorphoser pour une vie benthique.L’adhésion larvaire se fait au stade pédivéligère par sécrétion d’un bioadhésif produit par un organe spécialisé : le pied. Bien que l’huître Crassostrea gigas soit un organisme d’i…

Effects of Molecular Size on Diffusion and Desorption of Hindered Phenols in Low Density Polyethylene (LDPE)

Kenneth Möller、Thomas Gevert2018-12-12OpenAlex

The use of polymers in buildings as integrated components, e.g. barrier layers, is widespread. To protect polymers from degradation various additives are added. To fulfil their objectives properly the additives have to be mobile to some extent. However, too high a mobility leads to losses. Five hindered phenol antioxi…

High reflection from a one-dimensional array of graphene nanoribbons

Nathan Zhao、Zhexin Zhao、Ian Williamson 等 6 位作者2018-12-12arXiv (Cornell University)

We show that up to 90% reflectivity can be achieved by using guided plasmonic resonances in a one-dimensional periodic array of plasmonic nanoribbon. In general, to achieve strong reflection from a guided resonance system requires one to operate in the strongly over-coupled regime where the radiative decay rate domina…
