A topological method for classification of entanglements in crystal networks

E. V. Alexandrov, V. A. Blatov and D. M. Proserpio

Synopsis: A rigorous method is proposed to describe and classify topology of entanglements between periodic networks if the links are of Hopf type. The catenation pattern is unambiguously identified by so-called Hopf ring net that consists of barycenters of catenating rings with edges corresponding to the Hopf links.

Phyllotaxis: a non conventional crystalline solution to packing efficiency in situations with radial symmetry

J.-F. Sadoc, N. Rivier and J. Charvolin

Synopsis: Phyllotaxis, how to get a homogeneous distribution of points confined inside a flat disk.

On the optical theorem feasibility using a self-consistent wave approximation model for the grazing-incidence small-angle X-ray scattering from rough surfaces

F. N. Chukhovskii

Synopsis: Based on a self-consistent wave approximation for solving the integral wave equation, the grazing-incidence small-angle X-ray scattering from a random rough surface is considered to test the optical theorem feasibility.
