Morphology alterations vary with protein source. For example, Tyshenko et al. (1997) report wave-like, smooth-edged crystals forming with the AFP of the spruce budworm. The Space Group describes the total symmetry content of a Crystal from a microscopical perspective :The symmetry of the 3-dimensional crystal lattice, the points of which are occupied by motifs (atoms, ions or configurations of them) is considered including all translative symmetries.

Any crystalline material can exhibit the phenomenon. Allotropy refers to polymorphism for chemical elements.Polymorphism is of practical relevance to pharmaceuticals, agrochemicals, pigments, dyestuffs, foods, and explosives. 1.5 Crystal form and polymorphism. There are two crystal forms of ezetimibe, an anhydrate and a monohydrate [3]. Ezetimibe anhydrate is hygroscopic and will therefore absorb water from the atmosphere, converting to the monohydrate form.

About the crystal morphology control, Jackson.[17,18] firstly established a theory to predict and explain the solid-liquid interface morphology and proposed a parameter, named Jackson α factor, to predict the metal crystal morphology, and suggested that an interface would be faceted if α factor is greater than 2 (the value is reported as 3 by some other researchers[19,20]) and it would be

You can complete the definition of crystal morphology given by the English Definition dictionary with other English dictionaries: Wikipedia, Lexilogos, Oxford, Cambridge, Chambers Harrap, Wordreference, Collins Lexibase dictionaries, Merriam Webster Crystal protein morphology of Bacillus thuringiensis After screening the task is to identify strains harboring crystalline inclusions that might have potential for use as bioinsecticidal agent. Cultures were analyzed and viewed under Phase-contrasts microscope under 100X magnification to observe the presence of parasporal inclusions. Morphology¶. There is a class, ccdc.descriptors.CrystalDescriptors.Morphology, representing the morphology/habit of a crystal.
