  • Computational design of locally resonant acoustic metamaterials 

    Roca Cazorla, David; Yago Llamas, Daniel; Cante Terán, Juan Carlos; Lloberas Valls, Oriol; Oliver Olivella, Xavier (2019-03)
    Article
    Accés restringit per política de l'editorial
    The so-called Locally Resonant Acoustic Metamaterials (LRAM) are considered for the design of specifically engineered devices capable of stopping waves from propagating in certain frequency regions (bandgaps), this making ...

  • Effects of cholesterol on the binding of the precursor neurotransmitter tryptophan to zwitterionic membranes 

    Lu, Huixia; Martí Rabassa, Jordi (American Institute of Physics (AIP), 2018-10-25)
    Article
    Accés restringit per política de l'editorial
    The characterization of the microscopical forces between the essential a-amino-acid tryptophan, precursor of the neurotransmitter serotonin and of the hormone melatonin, and the basic components of cell membranes and their ...

  • Particle-cluster aggregation with dipolar interactions 

    Pastor Satorras, Romualdo; Rubí, J. Miguel (1995-06)
    Article
    Accés obert
    The properties of aggregates generated from an off-lattice, two-dimensional, particle-cluster aggregation model with dipolar interparticle interactions have been investigated. The fractal dimension seems to be a monotonically ...

  • Branch distribution in diffusion-limited aggregation: a maximum entropy approach 

    Pastor Satorras, Romualdo; Wagensberg, Jorge (1996-02-15)
    Article
    Accés restringit per política de l'editorial
    A new approach to the branching structure of diffusion-limited aggregation (DLA) clusters is proposed, in which the stress is laid not on the (traditionally used) order of the branches, but on their mass. The branch ...

  • Prandtl number dependence of convective fluids in tall laterally heated slots 

    Sánchez Umbría, Juan; Net Marcé, Marta (Springer, 2018-10-04)
    Article
    Accés restringit per política de l'editorial
    The influence of the Prandtl number on the stable stationary and periodic flows of the fluids contained in laterally heated slots under realistic conditions is analyzed by using continuation methods. Namely, non-slip ...

  • Multifractal properties of power-law time sequences: application to rice piles 

    Pastor Satorras, Romualdo (1997-11)
    Article
    Accés obert
    We study the properties of time sequences extracted from a self-organized critical system, within the framework of the mathematical multifractal analysis. To this end, we propose a fixed-mass algorithm, well suited to deal ...

  • Fractal properties of cluster of colloidal magnetic particles 

    Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (1998-05)
    Article
    Accés restringit per política de l'editorial
    We have studied the properties of clusters of colloidal magnetic particles generated from a 2D aggregation model with dipolar interparticle interactions. Particles diffuse off-lattice, experiencing dipolar 1 with the already ...

  • Cationic ionene as an n-dopant agent of poly(3,4-ethylenedioxythiophene) 

    Saborío González, Maricruz; Bertran Cànovas, Òscar; Lanzalaco, Sonia; Häring, Marleen; Díaz Díaz, David; Estrany Coda, Francesc; Alemán Llansó, Carlos (Royal Society of Chemistry (RSC), 2018-03-12)
    Article
    Accés restringit per política de l'editorial
    We report the reduction of poly(3,4-ethylenedioxythiophene) (PEDOT) films with a cationic 1,4-diazabicyclo[2.2.2]octane-based ionene bearing N,N0-(meta-phenylene)dibenzamide linkages (mPI). Our main goal is to obtain n-doped ...

  • Stochastic equation for the erosion of inclined topography 

    Pastor Satorras, Romualdo; Rothman, Daniel H. (American Institute of Physics (AIP), 1998-05-11)
    Article
    Accés obert
    We present a stochastic equation to model the erosion of topography with fixed inclination. The inclination causes the erosion to be anisotropic. A zero-order consequence of the anisotropy is the dependence of the prefactor ...

  • Segmental relaxation and partial crystallization of chain-extended Poly(l-lactic acid) reinforced with carboxylated carbon nanotube 

    Yousefzade, Omid; Valenti, Sofia; Puiggalí Bellalta, Jordi; Garmabi, Hamid; Macovez, Roberto (2019-02-15)
    Article
    Accés restringit per política de l'editorial
    Temperature-modulated differential scanning calorimetry (TMDSC) and broadband dielectric spectroscopy (BDS) were employed to study the glass transition, size of the cooperative rearranging regions (CRRs), crystallization ...

  • Long-range-interaction induced ordered structures in deposition processes 

    Pastor Satorras, Romualdo; Rubí Capaceti, José Miguel (American Institute of Physics (AIP), 1998-06-15)
    Article
    Accés obert
    We present a new model of sequential adsorption in which the adsorbing particles experience dipolar interactions. We show that in the presence of these long-range interactions, highly ordered structures in the adsorbed ...

  • The maximum entropy principle and the nature of fractals 

    Pastor Satorras, Romualdo; Wagensberg, Jorge (1998-06-19)
    Article
    Accés obert
    We apply the Principle of Maximum Entropy to the study of a general class of deterministic fractal sets. The scaling laws peculiar to these objects are accounted for by means of a constraint concerning the average content ...
