  • Curved fluid membranes behave laterally as an effective viscoelastic medium 

    Rahimi Lenji, Mohammad; DeSimone, Antonio; Arroyo Balaguer, Marino (2013-08-21)
    Article

    The lateral mobility of membrane inclusions is essential in biological processes involving membrane-bound macromolecules, which often take place in highly curved geometries such as membrane tubes or small organelles. Probe ...
  • Hydraulic fracture and toughening of a brittle layer bonded to a hydrogel 

    Lucantonio, Alessandro; Noselli, Giovanni; Trepat Guixer, Xavier; Arroyo Balaguer, Marino; DeSimone, Antonio (2015-10-28)
    Article
    Open Access
    Brittle materials propagate opening cracks under tension. When stress increases beyond a critical magnitude, then quasistatic crack propagation becomes unstable. In the presence of several precracks, a brittle material ...
  • Nonsingular isogeometric boundary element method for stokes flows in 3D 

    Heltai, Luca; Arroyo Balaguer, Marino; DeSimone, Antonio (2014-01)
    Article
    Open Access
    Isogeometric analysis (IGA) is emerging as a technology bridging computer aided geometric design (CAGD), most commonly based on Non-Uniform Rational B-Splines (NURBS) surfaces, and engineering analysis. In finite element ...
  • Relaxation dynamics of fluid membranes 

    Arroyo Balaguer, Marino; DeSimone, Antonio (2009-03)
    Article
    Open Access
    We study the effect of membrane viscosity in the dynamics of liquid membranes{possibly with free or internal boundaries{ driven by conservative forces (curvature elasticity and line tension) and dragged by the bulk dissipation ...
  • Reverse engineering the euglenoid movement 

    Arroyo Balaguer, Marino; Heltai, Luca; Millán, Raúl Daniel; DeSimone, Antonio (2012-10)
    Article
    Open Access
    Euglenids exhibit an unconventional motility strategy amongst unicellular eukaryotes, consisting of large-amplitude highly concerted deformations of the entire body (euglenoid movement or metaboly). A plastic cell envelope ...
  • Shape control of active surfaces inspired by the movement of euglenids 

    Arroyo Balaguer, Marino; DeSimone, Antonio (2014-01)
    Article
    Open Access
    We examine a novel mechanism for active surface morphing inspired by the cell body deformations of euglenids. Actuation is accomplished through in-plane simple shear along prescribed slip lines decorating the surface. Under ...
  • Smart helical structures inspired by the pellicle of euglenids 

    Noselli, Giovanni; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02)
    Article
    Restricted access - publisher's policy
    This paper deals with a concept for a reconfigurable structure bio-inspired by the cell wall architecture of euglenids, a family of unicellular protists, and based on the relative sliding of adjacent strips. Uniform sliding ...
  • Swimming Euglena respond to confinement with a behavioural change enabling effective crawling 

    Noselli, Giovanni; Beran, Alfred; Arroyo Balaguer, Marino; DeSimone, Antonio (2019-02-18)
    Article
    Open Access
    Some euglenids, a family of aquatic unicellular organisms, can develop highly concerted, large-amplitude peristaltic body deformations. This remarkable behaviour has been known for centuries. Yet, its function remains ...
