Spherulites are ideally spherical mineral growths formed by initial crystallization of a seed crystal, or crystallite , within a melt or a solution that grows outward in all directions.
Iron oxide is not a common catalyst support for other precious metals and the optimum crystallite size is larger for gold than for many other precious metal systems.
Beyond the crystallite regions, the protein chains continue into less orderly regions, where they are tangled together.
Furthermore, the rate decreases with time since as the solid is dissolved the surface area becomes smaller as there is less and less crystallite .
Only the stone floor upon which he stood seemed distinct: he could see the faces of the individual crystallites that made up the polished surface, and felt as if he would see the little lines of atoms if he knelt down close enough.
These ‘units' form aggregates / crystallites that precipitate in association with decaying organic matter in sediments.
The resulting crystals are riddled with flaws: they are really a patchwork of tiny crystallites welded together with their atomic lattices tilted at different angles.
A substantial curtailment of the growth of ice would amount to a substantial reduction of the absolute size of the ice crystallites .
Interestingly, cholesterol monohydrate crystallites formed in these two phospholipids exhibit a temperature of dehydration higher than that of pure cholesterol monohydrate crystals.
The term ‘texture’ refers to aspects of the spatial arrangement of the basic crystallites , the term ‘structure’ is used to describe the organization of textural elements to higher morphological characters.
