AbstractAbstract
[en] We apply an anisotropic version of the polymer reference interaction site model (PRISM) integral equation description of flexible polymers to analyze athermal liquid crystallinity. The polymers are characterized by a statistical segment length, σo, and by a physical hard-core thickness, d, that prevents the overlap of monomers on different chains. At small segment densities, ρ, the microscopic length scale d is irrelevant (as it must be in the universal semidilute regime), but becomes important in concentrated solutions and melts. Under the influence of the excluded volume interactions alone, the chains undergo a lyotropic, first-order isotropic-nematic transition at a concentration dependent upon the dimensionless ''aspect ratio,'' σo/d. The transition becomes weaker as d→0, becoming second order, as has been previously shown. We extend the theory to describe the transition of rigid, thin rods, and discuss the evolution of the anisotropic liquid structure in the ordered phase. (c) 2000 American Institute of Physics

AbstractAbstract
[en] A possibility of exciting steady convective motions in isotropic and anisotropic liquids under the action of a force produced by the radiation pressure of an acoustic wave with a spatially periodic transverse intensity distribution is considered theoretically and experimentally. Cells both with two rigid boundaries and with one free surface are studied. The fluxes lead to reorientation of the director of liquid crystal in the case of anisotropic liquid. As a result, it acquires a periodic distribution in the transverse plane. The phenomenon can be utilized for the imaging of acoustic fields with micro watt power

AbstractAbstract
[en] Full text of publication follows: In this poster, we briefly introduced the UV-visible absorption effect and the transparence of Linear Alkyl Benzene (LAB) as the liquid scintillator, which to be used in the Daya Bay Reactor Neutrino Experiment. Some experimental results on the attenuation length measurement, GC-MS, LC-MS and the improved distilling procedure for its quality control on the mass production have been demonstrated. (authors)
