Empirical molecular modelling of crystal growth modifiers

Controlling crystal growth with modifiers

Modifying crystal growth processes using additives is a well established approach to solving problems in many processes. Nature also makes extensive use of crystalline inorganic structures modified by soluble and insoluble organic materials. This Highlight discusses some of the recent and interesting developments in this area, with an emphasis on the control of crystal growth rates, covering bo...

Crystal Habit Modification Using Habit Modifiers

From molecular to continuum modelling of bistable liquid crystal devices

We study nematic equilibria on a square with tangent Dirichlet conditions on the edges, in three different modelling frameworks: (i) the off-lattice Hard Gaussian Overlap and Gay–Berne models; (ii) the lattice-based Lebwohl–Lasher model; and the (iii) two-dimensional Landau-de Gennes model. We compare the modelling predictions, identify regimes of agreement and in the Landaude Gennes case, find...

Empirical Modelling of Requirements

We propose a modelling process, based on observation and experiment, which is well-suited to reactive systems, and which provides an integrated environment for the requirements, specification and design phases of a development. The modelling method depends on application-specific knowledge which can be modified on-line by the intervention of the modeller. The process offers immediate experience...
