Curvature control of valence on nematic

Within a two-dimensional Landau–de Gennes tensorial formalism w tal ent der brid rtic val to maximize their mutual distance. The equilibrium texture with four +1⁄2 defects has been confirmed experimentally. 7 Besides their aesthetic appeal, nematic shells also have potential tion, while leaving g(S) 0. Zannoni et al.16 considered ellip-soidal particles, both uniaxial and biaxial; they performed several computer simulations based upon a lattice model and studied ilibrium texture upon varying rticular, they observed that the curvature of the substrate ions where the particle is more wo invariant local measures of aussian curvature. While the influence of curvature is undoubtable,16 there is no clue to which PAPER www.rsc.org/softmatter | Soft Matter D ow nl oa de d by U ni ve rs ita d i P av i
