    • Thermal Aging Effect on Mechanical Properties of Polyurethane 
      Article dans une revue avec comité de lecture
      FARZANEH, Sedigheh; ABDALLAH-ELHIRTSI, Sofiane; ESMAEILLOU, Bardia; NONY, Fabien; BARON, A; ccTCHARKHTCHI, Abbas (Taylor & Francis, 2014)
      This study concerns the effect of thermal aging on mechanical properties of polyurethane. Polyurethane samples were exposed at 85° and 120°C under inert atmosphere. Mechanical tests were carried out on these samples the ...
    • Molecular dynamics in electrospun amorphous plasticized polylactide fibers 
      Article dans une revue avec comité de lecture
      MONNIER, Xavier; DELPOUVE, Nicolas; BASSON, N; GUINAULT, Alain; DOMENEK, Sandra; SAITER, A; MALLON, P.E; DARGENT, Eric (Elsevier, 2015)
      The molecular dynamics in the amorphous phase of electrospun fibers of polylactide (PLA) has been investigated using the cooperative rearranging region concept. An unusual and significant increase of the cooperativity ...
    • Influence of thermal diffusion and shear-thinning during the leveling of nanoimprinted patterns in a polystyrene thin film 
      Article dans une revue avec comité de lecture
      TEYSSEDRE, Hubert; LANDIS, Stefan; GILORMINI, Pierre; ccREGNIER, Gilles (Springer Verlag, 2015)
      When capillary forces prevail, the leveling of the free surface of a fluid film is a natural phenomenon that has already found applicative interest either with brushmarks for paint coatings or for rheology on polymeric ...
    • Microstructure and Texture of Al2SixSn (x = 0, 4, 8 mass%) Alloys Processed by Equal Channel Angular Pressing 
      Article dans une revue avec comité de lecture
      GONZALEZ, Gonzalo; ccBRAHAM, Chedly; LEBRUN, Jean-Lou; CHASTEL, Yvan; SEILER, Wilfrid; FIGUEROA, Ignacio A. (Nihon Kinzoku Gakkai, 2012)
      The influence of Sn on the microstructure, microstrain and grain morphology in Al–2Si–xSn samples processed by ECAP is reported and discussed. The pseudo-binary Al–xSn alloys (where x = 0, 4, 8 mass%) were produced by ...
    • Problem of elastic anisotropy and stacking faults in stress analysis using multireflection grazing-incidence X-ray diffraction 
      Article dans une revue avec comité de lecture
      MARCISZKO, Marianna; BACZMANSKI, Andrzej; MIROSŁAW, Wrobel; SEILER, Wilfrid; WRONSKI, Sebastian; WAWSZCZAK, Roman; ccBRAHAM, Chedly (International Union of Crystallography, 2015)
      Multireflection grazing-incidence X-ray diffraction (MGIXD) was used to determine the stress- and strain-free lattice parameter in the surface layer of mechanically treated (polished and ground) tungsten and austenitic ...
    • Effect of crystallization on barrier properties of formulated polylactide 
      Article dans une revue avec comité de lecture
      COURGNEAU, Cécile; DOMENEK, Sandra; LEBOSSÉ, Régis; GUINAULT, Alain; AVÉROUS, Luc; DUCRUET, Violette (Wiley, 2012)
      Polylactide (PLA), a biodegradable polymer obtained from biomass, was formulated with a nucleating agent, talc, and a plasticizer, acetyl tributyl citrate, and cold crystallized in α and α′ form. The barrier properties of ...
    • Platicizer effect on network structure and hydrolytic degradation 
      Article dans une revue avec comité de lecture
      DERUE, Isabelle; GILORMINI, Pierre; VERDU, Jacques; VAULOT, Cyril; COQUILLAT, Marie; DESGARDIN, Nancy; VANDENBROUKE, Aude; ccRICHAUD, Emmanuel (Elsevier, 2015)
      The hydrolytic degradation of fully cured polyester-urethane networks polymerized in the presence of several weight ratios of triacetin was monitored by the residual concentration in elastically active chains obtained from ...
