    • From equilibrium lamellae to out-of-equilibrium cylinders in triblock copolymer nanolayers obtained via multilayer coextrusion 
      Article dans une revue avec comité de lecture
      MONTANA, Juan-Sebastian; MIQUELARD-GARNIER, Guillaume; ccRICHAUD, Emmanuel; ccROLAND, Sébastien (Elsevier, 2018)
      Multilayer coextrusion was used to obtain nanolayered films of self-assembled commercial triblock copolymer poly(methyl methacrylate-b-butyl acrylate-b-methyl methacrylate) (MAM) confined by poly(methyl methacrylate) (PMMA). ...
    • Tailoring residual stress profile of Selective Laser Melted parts byLaser Shock Peening 
      Article dans une revue avec comité de lecture
      KALENTICS, Nikola; BOILLAT, Eric; PEYRE, Patrice; CIRI´C-KOSTI´C, Sneˇzana´; BOGOJEVI, Nebojˇsa; E. LOGÉ, Roland (Elsevier, 2017)
      The paper describes a new approach in controlling and tailoring residual stress profile of parts made by Selective Laser Melting (SLM). SLM parts are well known for the high tensile stresses in the as – built state in the ...
    • A new approach to characterize very-low-level radioactive waste produced at hadron accelerators 
      Article dans une revue avec comité de lecture
      ZAFFORA, Biagio; MAGISTRIS, Matteo; CHEVALIER, Jean-Pierre; LUCCIONI, Catherine; SAPORTA, Gilbert; ULRICI, Luisa (Elsevier, 2017)
      Radioactive waste is produced as a consequence of preventive and corrective maintenance during the operation of high-energy particle accelerators or associated dismantling campaigns. Their radiological characterization ...
    • Dislocation Core Structure at Finite Temperature Inferred by Molecular Dynamics Simulations for 1,3,5-Triamino-2,4,6- trinitrobenzene Single Crystal 
      Article dans une revue avec comité de lecture
      LAFOURCADE, Paul; DENOUAL, Christophe; MAILLET, Jean-Bernard (American Chemical Society, 2017)
      The dislocation core structures and elastic properties of the insensitive energetic molecular crystal 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) are investigated as a function of pressure and temperature. A new method is ...
    • In situ observation of g-ZrH formation by X-ray diffraction 
      Article dans une revue avec comité de lecture
      BJERKEN, Christina; STEUWER, Axel; WANG, Z; DANIELS, J; ANDRIEUX, Jérôme; BLOMQVIST, Jakob; ZANELLATO, Olivier; MAIMAITIYILI, Tuerdi (Elsevier, 2017)
      We report on the measurement of the formation of γ-ZrH during in situ gaseous charging. The measurements were undertaken using high-energy synchrotron X-ray diffraction. Experimental observation shows that γ-ZrH can form ...
    • Multi-scale and multi-technical analysis of the thermal degradation of poly(ether imide) 
      Article dans une revue avec comité de lecture
      COURVOISIER, Emilie; BICABA, Yoann; ccCOLIN, Xavier (Elsevier, 2018)
      The thermal degradation of PEI has been studied in wide ranges of temperature (between 180 and 250 °C) and oxygen partial pressure (between 0.21 and 50 bars). On one hand, the chemical ageing mechanisms have been analysed ...
    • On the role of hydrogen bonding on water absorption in polymers 
      Article dans une revue avec comité de lecture
      GILORMINI, Pierre; VERDU, Jacques (Elsevier, 2018)
      A kinetic model is proposed for the absorption of water in polymers. The process of bonding-debonding water molecules is described by two opposite reactions with different rate constants, and the key role of the concentration ...
