    • Formation of metallic nanoclusters in oxygen deficient indium tin oxide films 
      Article dans une revue avec comité de lecture
      PERRIÉRE, Jacques; HÉBERT, Christian; PETITMANGIN, Aline; PORTIER, Xavier; SEILER, Wilfried; NISTOR, Magdalena G. (American Institute of Physics, 2011)
      The composition, structure, microstructure, and properties of indium tin oxide films grown by pulsed laser deposition at room temperature and under vacuum were studied. The films are highly nonstoichiometric, with about ...
    • Kinetics of chlorine-induced polyethylene degradation in water pipes 
      Article dans une revue avec comité de lecture
      DEVILLIERS, Clémence; LAIARINANDRASANA, Lucien; OBERTI, Sandrine; GAUDICHET-MAURIN, Emmanuelle; ccFAYOLLE, Bruno (Elsevier, 2011)
      The presence of chlorine in drinking water supplies in many countries creates the undesirable side effect of causing a relatively under investigated degree of polymer degradation in the polyethylene pipes used for transport. ...
    • Modelling of thermal oxidation of phosphite stabilized polyethylene 
      Article dans une revue avec comité de lecture
      DJOUANI, Fatma; VERDU, Jacques; ccFAYOLLE, Bruno; ccRICHAUD, Emmanuel (Elsevier, 2011)
      The thermal oxidation behaviour of polyethylene films stabilized by various weight ratios of organophosphites (Irgafos 168) has been studied at selected temperatures. The duration of the induction period was found to ...
    • Ring tests on high density polyethylene: Full investigation assisted by finite element modeling 
      Article dans une revue avec comité de lecture
      LAIARINANDRASANA, Lucien; DEVILLIERS, Clémence; OBERTI, Sandrine.; GAUDICHET, E; LUCATELLI, Jean Marc; ccFAYOLLE, Bruno (Elsevier, 2011)
      In order to characterize the mechanical behavior of HDPE pipes, the ASTM D 2290-04 standard recommends carrying out tensile tests on notched rings, cut out from the pipe. This very simple test is also utilized to investigate ...
    • A kinetic model for predicting PET macromolecular changes during its mechanical recycling 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (EDP Sciences, 2011)
      The rheometer cavity has been used to analyse, in carefully controlled exposure conditions, the macromolecular changes generated by the mechanical recycling of PET during its extrusion. Isothermal ageing tests at 280 °C, ...
    • Kinetic analysis and modelling of PET macromolecular changes during its mechanical recycling by extrusion 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (Elsevier, 2011)
      The rheometer cavity has been chosen to analyze, in carefully controlled exposure conditions, the PET macromolecular changes generated during its mechanical recycling by extrusion. Isothermal ageing experiments at 280 °C, ...
    • Effect of gamma irradiation on tensile properties of low molecular weight polyethylene samples 
      Article dans une revue avec comité de lecture
      MONCHY-LEROY, Carole; VERDU, Jacques; ccCOLIN, Xavier (Elsevier, 2011)
      Three high density polyethylene (PE) samples of different origins, with weight average molar masses ranging from 38 to 63kgmol-1 and displaying a semi-ductile behavior with strain at break εR values of the order of 100-140%, ...
