  • Computational analysis of ion cyclotron resonance frequency heating for DEMO 

    Gallart Escolà, Dani (Universitat Politècnica de Catalunya, 2015-06)
    Master thesis
    Open Access
    Ion cyclotron resonance frequency heating (ICRH) is one of the most important mechanisms to heat fusion plasma. The magnetic field generated by the magnetic coils forces ions to follow a cyclotron trajectory around the ...
  • Degradation of Monochloroacetic acid by aluminium modified Fenton process 

    Llort Sala, Albert (Universitat Politècnica de Catalunya, 2017-06)
    Master thesis
    Open Access
    This study investigates the degradation of monochloroacetic acid (MCA) by aluminium modified Fenton Process. Fenton reaction and its modifications using zero-­‐valent aluminium (ZVAl) and Al3+ io ...
  • Effects of concentration on structure, dielectric, and dynamic properties of aqueous NaCl solutions using a polarizable model 

    Sala Viñas, Jonàs; Guàrdia Manuel, Elvira; Martí Rabassa, Jordi (American Institute of Physics (AIP), 2010-06-03)
    Article
    Restricted access - publisher's policy
    The study of NaCl solutions in water at finite concentration, explicitly including polarization in water molecules and ions, has been carried out by molecular dynamics simulations. A comparison of the RPOL polarizable model ...
  • Heating bulk ions in DEMO with ICRF waves 

    Gallart, Dani; Mantsinen, Mervi; Kazakov, Yevgen (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    Ion cyclotron resonance frequency heating (ICRF) is one of the auxiliary heating schemes presently envisaged for ITER and DEMO. In this paper we analyse the potential of ICRF waves to heat the fuel ions in DEMO. Our ...
  • On the structure of water and chloride ion interactions with a peptide backbone in solution 

    Busch, Sebastian; Pardo Soto, Luis Carlos; O'Dell, William B.; Bruce, Chrystal D.; Lorenz, Christian D.; McLain, Sylvia E. (2013-12-28)
    Article
    Restricted access - publisher's policy
    The arrangement of water and chloride ions around a model peptide (glycyl-L-prolyl-glycine-NH2) was investigated using Molecular Dynamics (MD) simulations and complementary Empirical Potential Structure Refinement (EPSR) ...
  • Specific ion binding at phospholipid membrane surfaces 

    Martí Rabassa, Jordi; Calero Borrallo, Carles; Bonomi, Massimiliano; Yang, Jing (2015-08-18)
    Article
    Open Access
    Metal cations are ubiquitous components in biological environments and play an important role in regulating cellular functions and membrane properties. By applying metadynamics simulations, we have performed systematic ...
  • Specific ion effects in aqueous eletrolyte solutions confined within graphene sheets at the nanometric scale 

    Sala Viñas, Jonàs; Guàrdia Manuel, Elvira; Martí Rabassa, Jordi (2012-08-14)
    Article
    Restricted access - publisher's policy
    The underlying mechanisms of specific ion effects on structure and dynamics of aqueous solutions have been long debated. On the other hand, the role of polarization at hydrophobic interfaces when aqueous electrolytes are ...
  • Towards cavity enhanced detection of single ions in the solid-state 

    Van Valkenhoef, Céline Hélène Ida (Universitat Politècnica de Catalunya, 2018-09-06)
    Master thesis
    24 months embargo
    The goal of this master thesis was to take initial steps towards cavity-enhanced detection of single rare-earth ions in the solid state. A fibre microcavity set-up for use with Praseodymium-doped nanocrystals was designed, ...
  • Transport of Metallic Ions through Polyaniline-containing composite membranes 

    Ferreira, Carlos; Casanovas, Jordi; Rodrigues, Marco A. S.; Muller, Francielli; Armelín Diggroc, Elaine Aparecida; Alemán Llansó, Carlos (2010-09-30)
    Article
    Open Access
    The extraction of Na+, Ni2+, and Cr3+ using six different membranes made of polyaniline composited with high-impact polystyrene, which differ in the doping agent and/or the preparation method, has been investigated. The ...
