Two-dimensional Crystallisation on Spherical Surfaces
نویسندگان
چکیده
We report results of a computational study on 2D crystallisation for a 25-particle Lennard-Jones system on a spherical surface, as a function of radius. The energy is minimised using simulated annealing and steepest descent methods. Different crystalline arrangements with clear energy minima are found at different radii. Qualitatively, most of the observed phenomena are representative also for systems with much larger numbers of particles.

متن کاملAn Investigation of the Effects of Self-Assembled Monolayers on Protein Crystallisation
Most protein crystallisation begins from heterogeneous nucleation; in practice, crystallisation typically occurs in the presence of a solid surface in the solution. The solid surface provides a nucleation site such that the energy barrier for nucleation is lower on the surface than in the bulk solution. Different types of solid surfaces exhibit different surface energies, and the nucleation bar...
متن کاملUse of Zernike Polynomials and SPGD Algorithm for Measuring the Reflected Wavefronts from the Lens Surfaces
Recently, we have demonstrated a new and efficient method to simultaneously reconstruct two unknown interfering wavefronts. A three-dimensional interference pattern was analyzed and then Zernike polynomials and the stochastic parallel gradient descent algorithm were used to expand and calculate wavefronts. In this paper, as one of the applications of this method, the reflected wavefronts from t...
متن کاملPhase transition of triangulated spherical surfaces with elastic skeletons
A first-order transition is numerically found in a spherical surface model with skeletons, which are linked to each other at junctions. The shape of triangulated surfaces is maintained by skeletons, which have a one-dimensional bending elasticity characterized by the bending rigidity b, and the surfaces has no two-dimensional bending elasticity except at the junctions. The surfaces swell and be...
