Analysis of the structure and morphology of fenoxycarb crystals [PDF]
Journal of Molecular Graphics and Modelling, 2014 In this paper we have explored the relationship between surface structure and crystal growth and morphology of fenoxycarb (FC). Experimental vs. predicted morphologies/face indices of fenoxycarb crystals are presented. Atomic-scale surface structures of the crystalline particles, derived from experimentally-indexed single crystals, are also modelled ...

Preparation of Enzyme Crystals with Tunable Morphology in Membrane Crystallizers
Industrial & Engineering Chemistry Research, 2005 Trypsins were crystallized by using membrane crystallization techniques, both in static and dynamic configurations. Crystal size distribution analysis revealed the high uniformity in size of the products that is achievable. Crystals produced by using membrane crystallization methods are more uniform than those obtained in conventional batch experiments.
