    • Direct measurement of Lighthill’s energetic efficiency of a minimal magnetic microswimmer 

      Calero, Carles; García Torres, José Manuel; Ortiz Ambriz, Antonio; Sagués Mestres, Francesc; Pagonabarraga, I.; Tierno, Prieto (2019-09-27)
      Article
      Open Access
      The realization of artificial microscopic swimmers able to propel in viscous fluids is an emergent research field of fundamental interest and vast technological applications. For certain functionalities, the efficiency ...
    • Enhancement of swimmer diffusion through regular kicks: analytic mapping of a scale-independent parameter space 

      Jurado Romero, Arnau; Calero, Carles; Rey Oriol, Rosendo (Institute of Physics (IOP), 2024-06-21)
      Article
      Restricted access - publisher's policy
      Depending on their mechanism of self-propulsion, active particles can exhibit time-dependent, often periodic, propulsion velocity. The precise propulsion velocity profile determines their mean square displacement and their ...
    • High energy vibrational excitations of nitromethane in liquid water 

      Jurado Romero, Arnau; Calero, Carles; Sibert III, Edwin L.; Rey Oriol, Rosendo (2023-05-15)
      Article
      Open Access
      The pathways and timescales of vibrational energy flow in nitromethane are investigated in both gas and condensed phases using classical molecular mechanics, with a particular focus on relaxation in liquid water. We monitor ...
    • Magnetically tunable bidirectional locomotion of a self-assembled nanorod-sphere propeller 

      García Torres, José Manuel; Calero, Carles; Sagués Mestres, Francesc; Pagonabarraga, I.; Tierno, Prieto (2018-04-25)
      Article
      Open Access
      Field-driven direct assembly of nanoscale matter has impact in disparate fields of science. In microscale systems, such concept has been recently exploited to optimize propulsion in viscous fluids. Despite the great ...
    • Modeling and simulation of lipid membranes 

      Martí Rabassa, Jordi; Calero, Carles (Multidisciplinary Digital Publishing Institute (MDPI), 2022-05-25)
      Article
      Open Access
      Cell membranes separate the interior of cells and the exterior environment, providing protection, controlling the passage of substances, and governing the interaction with other biomolecules and signalling processes. They ...
    • Modeling and simulation of lipid membranes 

      Martí Rabassa, Jordi; Calero, Carles (Multidisciplinary Digital Publishing Institute (MDPI), 2022-08-03)
      Book

    • Propulsion and energetics of a minimal magnetic microswimmer 

      Calero, Carles; García Torres, José Manuel; Ortiz, Antonio; Sagues, Francesc; Pagonabarraga, Ignacio; Tierno, Pietro (Royal Society of Chemistry, 2020-07-28)
      Article
      Open Access
      In this manuscript we describe the realization of a minimal hybrid microswimmer, composed of a ferromagnetic nanorod and a paramagnetic microsphere. The unbounded pair is propelled in water upon application of a swinging ...
    • Self-thermophoresis at the nanoscale using light induced solvation dynamics 

      Rey Oriol, Rosendo; Calero, Carles (2020-03-30)
      Article
      Open Access
      Downsizing microswimmers to the nanoscale, and using light as an externally controlled fuel, are two important goals within the field of active matter. Here we demonstrate using all-atom molecular dynamics simulations that ...
    • Structure and dynamics of water at carbon-based interfaces 

      Martí Rabassa, Jordi; Calero, Carles; Franzese, Giancarlo (2017-03-21)
      Article
      Open Access
      Water structure and dynamics are affected by the presence of a nearby interface. Here, first we review recent results by molecular dynamics simulations about the effect of different carbon-based materials, including ...
    • Swimming modes of self-assembled magnetic micropropeller

    • Unveiling the rolling to kayak transition in propelling nanorods with cargo trapping and pumping 

      Junot, Gaspard; Calero, Carles; García Torres, José Manuel; Pagonabarraga, Ignacio; Tierno, Pietro (American Chemical Society, 2022-01-01)
      Article
      Open Access
      Covenantee:   Universitat de Barcelona
      Magnetic nanorods driven by rotating fields in water can be rapidly steered along any direction while generating strong and localized hydrodynamic flow fields. Here we show that, when raising the frequency of the rotating ...
