    • 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 ...
    • 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 ...
    • 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 ...
