Quantitative theory of diffraction by ordered coaxial nanotubes: reciprocal lattice and diffraction pattern indexing
The reciprocal lattice of an ordered coaxial nanotube, its relation to nanotube lattice parameters and the diffraction pattern indexing approach are developed on the basis of a quantitative theory of diffraction.
A topological coordinate system for the diamond cubic grid
The diamond cubic grid is one of the usual cubic crystal structures. The Voronoi cells are triakis truncated tetrahedra having four hexagon and 12 triangle faces, 30 edges and 16 vertices. A symmetric coordinate system is presented that addresses not only the voxels, but also the faces, edges and vertices between them. In this way, not only volumes, but also surfaces, or paths containing edges can be easily described and visualized.
