  • Title: X-ray scattering of nematic liquid crystal nanodispersion with negative dielectric anisotropy [Invited].
    Author: Lorenz A, Zimmermann N, Kumar S, Evans DR, Cook G, Fernández Martínez M, Kitzerow HS.
    Journal: Appl Opt; 2013 Aug 01; 52(22):E1-5. PubMed ID: 23913081.
    Abstract:
    A nematic liquid crystal (LC) mixture was doped with harvested ferroelectric BaTiO3 nanoparticles and investigated with wide- and small-angle x-ray scattering upon heating from the nematic to the isotropic phase. At moderate temperatures, colloidal crystallites were observed. LC test cells with homeotropic anchoring were placed in the x-ray beam and the realignment of the LC director was investigated upon applying an electric field.
