    • Ab Initio calculation of parameters for electron and spin transport in organic crystals 

      ROYCHOUDHURY, SUBHAYAN (Trinity College Dublin. School of Physics. Discipline of Physics, 2018)
      Organic semiconductors offer several crucial advantages over their inorganic counterparts in electronic and spintronic applications. Besides offering structural advantages such as variety and flexibility, organic semiconductors ...

    • The continuum theory of shear localization in two-dimensional foam 

      HUTZLER, STEFAN; WEAIRE, DENIS (2010)
      We review some recent advances in the rheology of two-dimensional liquid foams, which should have implications for three-dimensional foams, as well as other mechanical systems that have a yield stress. We focus primarily ...

    • Instabilities in liquid foams 

      WEAIRE, DENIS (2007)
      Instabilities play a central role in the physics of foams. Some that change the topology of a dry foam are indicated by the laws promulgated by Plateau in his 1873 book. Their occurrence is less clearly predictable in ...

    • On the Road Again: Metal Foams Find Favor 

      WEAIRE, DENIS LAWRENCE (American Institute of Physics, 2002)
      The three states of matter are well represented by earth, sea, and sky. God saw that it was good, and so did many generations of physics lecturers. But purity is obscurity, as Ogden Nash reminded us. The rich variety of ...

    • Onset of rigidity for stretched string networks 

      HUTZLER, STEFAN; WEAIRE, DENIS LAWRENCE (Institute of Physics, 2005)
      We define and analyse an elementary model for a network of strings with random natural lengths. As this system is expanded, a threshold is reached where some of the strings form a taut string network. Further expansion ...

    • Optimising Transport in a Homogeneous Network 

      WEAIRE, DENIS LAWRENCE (American Physical Society, 2004)
      Many situations in physics, biology, and engineering consist of the transport of some physical quantity through a network of narrow channels. The ability of a network to transport such a quantity in every direction can ...

      Many situations in physics, biology, and engineering consist of the transport of some physical quantity through a network of narrow channels. The ability of a network to transport such a quantity in every direction can ...

    • Pre-empting Plateau: The nature of topological transitions in foam 

      HUTZLER, STEFAN; WEAIRE, DENIS LAWRENCE (Institute of Physics, 2007)
      When the area of a face in a dry foam approaches zero in some quasistatic processes, Plateau?s rules dictate that there must be an instability. This is more subtle than generally supposed.We argue that it is generally ...

    • Rheological properties of the soft disk model of 2D foams 

      HUTZLER, STEFAN; WEAIRE, DENIS (2008)
      The soft-disk model previously developed and applied by Durian D. J. Durian, Phys. Rev. Lett. 75, 4780 1995 is brought to bear on problems of foam rheology of longstanding and current interest, using twodimensional systems. ...

    • Wall slip of bubbles in foams 

      WEAIRE, DENIS LAWRENCE (American Institute of Physics, 2006)
      We present a computational analysis of the flow of liquid foam along a smooth wall, as encountered in the transport of foams in vessels and pipes. We concentrate on the slip of the bubbles at the wall and present some ...
