  • Finlayson, Christopher Edward; Goddard, Chris; Papachristodoulou, Elpida; Snoswell, David R. E.; Kontogeorgos, Andreas; Spahn, Peter; Hellmann, G. Peter; Hess, Ortwin; Baumberg, Jeremy J. (2011)
    We demonstrate the production of high-quality polymer opal fibers in an industrially-scalable process. These fibers exhibit structural color, based on the self-assembly of sub-micron core-shell particles, with a spectrum ...
  • Geissert, Matthias; Heck, Horst; Hieber, Matthias; Wood, Ian (Birkhäuser Basel, 2005)
    Let Ω be an exterior domain in It is shown that Ornstein-Uhlenbeck operators L generate C0-semigroups on Lp(Ω) for p ∈ (1, ∞) provided ∂Ω is smooth. The method presented also allows to determine the domain D(L) of L and ...

  • Brown, Daniel; Schrijver, Carolus (2000-06-27)
    The magnetic field in the outer solar atmosphere is frequently distorted by flares. In some cases, a fraction of the field exhibits a rapidly damped oscillation (Schrijver et al.; Aschwanden et al.). If this is a resonating ...
  • Walters, K.; Binding, David M.; Bell, D. (2006-10)
    In this paper, we give detailed attention to a relatively recent method for the determination of the linear dynamic properties of viscoelastic systems, namely, the so-called oscillatory squeeze flow (OSF) technique. We ...
  • Bishop, Gerard J.; Kersley, L.; Malan, D.; Pryse, Sian (2006-10-01)
    Measurements of total electron content, obtained by monitoring satellite transmissions at stations in the United Kingdom during a period of 12 months, have been used to characterize the structure and dynamics of the main ...
  • McDonough, Thomas P.; Key, Jennifer D.; Mavron, Vassili (2008-03)
    Explicit PD-sets are found for partial permutation decoding of the generalized Reed-Muller codes from the affine geometry designs of points and lines in dimension 3 over the prime field of order p, using the information ...
  • Mishuris, Gennady; Movchan, Natasha; Movchan, Alexander; Piccolroaz, Andrea (2012-01-14)
    The paper addresses the problem of a Mode III interfacial crack advancing quasi-statically in a heterogeneous composite material, that is a two-phase material containing elastic inclusions, both soft and stiff, and defects, ...
  • Piccolroaz, Andrea; Movchan, Alexander; Mishuris, Gennady (2011-09-06)
    We consider the perturbation problem of a Mode III interfacial crack. The perturbation is of geometrical type and can be both perturbation of the crack faces and perturbation of the interface, which can deviate from the ...
  • Mishuris, Gennady; Mishakin, V.; Linkov, A. M.; Alford, N.; Fradkin, L.; Dobroskok, A. (2009)
    Real-time control of the direction of a propagating crack is little explored area of management of structural integrity. We have examined it with experiments on quasi-static (slow) cracks in PMMA (Polymethyl-Methacrylate). ...
  • Finlayson, C. E.; Whitney, A. D. (2010-03-10)
    We report a photophysical study of photovoltaic blends containing perylene-substituted polyisocyanide (pery-PIC) materials, using time-correlated single photon counting and photo-induced absorption spectroscopy, and compare ...
  • Mughal, Adil; Chan, H. K.; Weaire, D. (2011-03-16)
    We develop a simple analytical theory that relates dense sphere packings in a cylinder to corresponding disk packings on its surface. It applies for ratios R = D/d (where d and D are the diameters of the hard spheres and ...
  • Winningham, D.; Grande, Manuel; Lundin, R.; Barabash, S. (2006)
    Auroras are caused by accelerated charged particles precipitating along magnetic field lines into a planetary atmosphere, the auroral brightness being roughly proportional to the precipitating particle energy flux. The ...
  • Greaves, George Neville; Greer, A. L.; Lakes, R. S.; Rouxel, T. (2011-10-24)
    In comparing a material's resistance to distort under mechanical load rather than to alter in volume, Poisson's ratio offers the fundamental metric by which to compare the performance of any material when strained elastically. ...
  • McMillan, Paul F.; Wilding, Martin Charles; Wilson, Myra Scott; Daisenberger, Dominik; Mezouar, Mohamed; Greaves, G. Neville (2007-10-17)
    Phase transitions in the liquid state can be related to pressure-driven fluctuations developed in the density (i.e., the inverse of the molar volume; ρ = 1/V) or the entropy (S(T )) rather than by gradients in the chemical ...
  • Greaves, G. N. (ScolarOne, 2011-01-21)
    The physics of critical phenomena is well established in systems as diverse as molecular fluids, crystalline alloys and magnetic materials. As the critical point is approached, the susceptibility increases anomalously and ...
  • McMillan, Paul F.; Wilson, Mark; Wilding, Martin C. (2003)
    Supercooled liquids in the Y2O3–Al2O3 system undergo a liquid–liquid phase transition between a high-temperature, high-density amorphous polymorph (HDA form), and one with lower density that is stable at lower temperature ...
  • Plakhov, A. Y. (2004)
    The Monge-Kantorovich problem on finding a measure realizing the transportation of mass from to at minimum cost is considered. The initial and resulting distributions of mass are assumed to be the same and the cost of the ...
  • Hutzler, Stefan; van der Net, Antje; Weaire, Denis; Cox, Simon; Janiaud, Eric (2007-01)
    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 ...
  • Deb, Sudip K.; Wilding, Martin C.; Somayazulu, Maddury; McMillan, Paul F. (2001-11-29)
    Crystalline and amorphous forms of silicon are the principal materials used for solid-state electronics and photovoltaics technologies. Silicon is therefore a well-studied material, although new structures and properties ...
