  • Flow-driven transition and associated velocity profiles in a nematic liquid-crystal cell 

    Jewell, Sharon A.; Cornford, Stephen Leslie; Yang, Fuzi; Cann, P. S.; Sambles, J. Roy (American Physical Society, 2009)
    The alignment properties and distribution of flow speed during Poiseuille flow through a microchannel of a nematic liquid crystal in a cell with homeotropic surface alignment has been measured using a combination of ...
  • Surface-plasmon-enhanced light scattering from microscopic spheres 

    Jory, M. J.; Cann, P. S.; Sambles, J. Roy; Perkins, E. A. (American Institute of Physics, 2003)
    The enhanced light scattering from microscopic latex spheres placed in the optical field associated with a surface-plasmon resonance is explored. Spheres of 200 nm diameter are placed on an optically thin gold film that ...
