    • Comparison of drop evaporation models on hot surface 

      González Esteve, Adrià (Universitat Politècnica de Catalunya / Politecnico di Milano, 2014)
      Bachelor thesis
      Open Access
      Covenantee:   Politecnico di Milano
      This project is a study of how a sessile drop evaporates on a hot surface. Some existing models of droplet evaporation are explained, understood, simulated and compared. This project also provides an expression of drop ...
    • Correlation between surface damage and mechanical properties at micro- and nanometric length scale for WC-Co hardmetals 

      Canals Pou, Alberto María (Universitat Politècnica de Catalunya, 2014-10)
      Master thesis (pre-Bologna period)
      Open Access
      Cemented carbides (WC-Co) are ceramic-metal composite materials made by hard tungsten carbide particles bonded through a metallic binder matrix, mainly of cobalt. It is a hard material characterized by an exceptional ...
    • Diffusion on Solid Surface: anomalous is Normal 

      Sancho, Jose Maria; Lacasta Palacio, Ana María; Lindenberg, K.; Sokolov, Igor M.; Romero, A. H. (American Physical Society, 2004-06-23)
      Article
      Open Access
      We present a numerical study of classical particles diffusing on a solid surface. The particles’ motion is modeled by an underdamped Langevin equation with ordinary thermal noise. The particle-surface interaction is described ...
    • Experimental study of the influence of an electric field on the shape of a droplet 

      Romero Herreros, Núria (Universitat Politècnica de Catalunya / Université Libre de Bruxelles, 2014)
      Master thesis
      Open Access
      The electrowetting effect has emerged as an important research topic in recent years. Manipulation of droplets by electric fields has been extensively studied employing different setups, the most common being ...
    • From subdiffusion to superdiffusion of particles on solid surfaces 

      Lacasta Palacio, Ana María; Sancho, Jose Maria; Sokolov, Igor M.; Lindenberg, K. (American Physical Society, 2004-11-15)
      Article
      Open Access
      We present a numerical and partially analytical study of classical particles obeying a Langevin equation that describes diffusion on a surface modeled by a two dimensional potential. The potential may be either periodic ...
    • Grinding effects on surface integrity and mechanical strength of WC-Co cemented carbides 

      Yang, Jing; Odén, Magnus; Johansson-Jõesaar, M.P.; Llanes Pitarch, Luis Miguel (Elsevier, 2014)
      Article
      Open Access
      In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface ...
    • Particle separation by external fields on periodic surfaces 

      Sancho, Jose Maria; Khoury, M.; Lindenberg, K.; Lacasta Palacio, Ana María (http://dx.doi.org/10.1063/1.478548, 2005-11-30)
      Article
      Open Access
      Particles moving on perfect periodic surfaces under the influence of external forces may move along directions that deviate from that of the force. We briefly recall previous results for transport of particles on surfaces ...
    • Unsolved problems of surface diffusion at low friction 

      Lindenberg, K.; Lacasta Palacio, Ana María; Sancho Herrero, Jose Maria; Romero, A. H. (American Institute of Physics, 2005-11-30)
      Article
      Restricted access - publisher's policy
      Surface transport and diffusion at low damping reveals a number of unexplained or at least not systematically explained behaviors. Here we present two problems that require further study for a full understanding. One ...
    • Weak disorder in periodic potentials: anomalous transport and diffusion 

      Lindenberg, Katja; Sancho, Jose Maria; Khoury Arvelo, María José; Lacasta Palacio, Ana María (2012-03-31)
      Article
      Restricted access - publisher's policy
      Particles driven through a periodic potential by an external constant force are known to exhibit a pronounced peak of the diffusion around the critical deterministic force that defines the transition between locked and ...
