  • Plasmonic fractal antennas 

    López Menchón, Héctor (Universitat Politècnica de Catalunya, 2016-06)
    Bachelor thesis
    Open Access
    We study the effects of using fractal shapes on the design of nanoantennas at optical geometries.
  • Scrape Off Layer turbulence and flow velocity measurements with the Li-beam diagnostic 

    Rodriguez Serra, Jorge (Universitat Politècnica de Catalunya, 2016-09)
    Master thesis (pre-Bologna period)
    Open Access
    This work studies the behavior of the plasma in the outer part of the vessel, where the magnetic field lines are no longer closed, this part in called scrape off layer. The machine studied is the experimental fusion ...
  • Simulación de la formación de plasma en el mecanizado por electroerosión 

    Villagomez Galindo, Miguel; González Rojas, Hernan Alberto (Academia Journals, 2017)
    Conference report
    Open Access
    El proceso de mecanizado por electroerosión es una técnica de manufactura no convencional caracterizada por descargas eléctricas controladas que liberan tal cantidad de energía que es capaz de transformar en plasma el ...
  • Simulations of Alfvénic modes in TJ-II Stellarator 

    Rakha, Allah; Mantsinen, M. J.; López-Fraguas, A.; Castejón, F.; Pablos, J.L. de; Melnikov, A.V.; Sharapov, S. E.; Spong, D. A. (Barcelona Supercomputing Center, 2017-05-04)
    Conference report
    Open Access
    Alfvénic modes are one of the subclass of instabilities prevalent in burning plasmas due to interaction of energetic particles with background plasma. In this paper we investigate the properties of these modes with 3D ...
  • Simulations of high-enthalpy gases in an Electric Arc Heater – Study of Equilibrium vs. Non- Equilibrium assumptions and Uncertainty Quantifications of an Arc Jet 

    Jiménez Miró, José Ángel (Universitat Politècnica de Catalunya / Insitut Supérieur de l'Aéronautique et de l'Espace, 2011)
    Master thesis (pre-Bologna period)
    Restricted access - author's decision
    Space exploration has experienced exceptional advances the last years since the NASA’s Apollo missions landed man on the moon. In spite of all the discoveries and advances in computational power, the heat flux on the ...
  • Topographical and wettability effects of post-discharge plasma treatments on macroporous polystyrene-divinylbenzene solid foams 

    Canal Barnils, Cristina; Gaboriau, Freddy; Vílchez, Alejandro; Erra Serrabasa, Pilar; García-Celma, María José; Esquena, Jordi (2009)
    Article
    Restricted access - publisher's policy
    The aim of this study was to evaluate the morphological characteristics and wetting properties of polystyrene-divinylbenzene (PS-DVB) solid foams and their modification through post-discharge plasmas. The low-density solid ...
  • Transmission of N atoms through PP membranes for nitrogen flowing post-discharge sterilisation processes 

    Ricard, André; Canal Barnils, Cristina (2010)
    Article
    Restricted access - publisher's policy
    This work reports on the results of investigations conducted with three layered polypropylene (PP) membranes which were exposed to a N2 flowing microwave (100 W) post discharge, at several flow rates (0.03–1 Slm) and at ...
  • White paper on the future of plasma science and technology in plastics and textiles 

    Cvelbar, Uros; Walsh, James L.; Cernák, Mirko; Labay, Cédric Pierre; Canal Arias, José María; Canal Barnils, Cristina (2019-01-01)
    Article
    Open Access
    Covenantee:  Inštitut "Jožef Stefan"
    This white paper considers the future of plasma science and technology related to the manufacturing and modifications of plastics and textiles, summarizing existing efforts and the current state‐of‐art for major topics ...
