Growth and form of spherulites.
Many structural materials (metal alloys, polymers, minerals, etc.) are formed by quenching liquids into crystalline solids. This highly nonequilibrium process often leads to polycrystalline growth patterns that are broadly termed "spherulites" because of their large-scale average spherical shape. Despite the prevalence and practical importance of spherulite formation, only rather qualitative co...
متن کاملThe organization of cholesteric spherulites
2014 Germs of cholesteric liquids were studied in classical mixtures of nematic compounds (MBBA, PAA) with a twisting substance (cholesterol benzoate). These germs were also studied with different polymers of biological interest : synthetic polypeptides (PBLG), nucleic acids (DNA) and polysaccharides (xanthan). Germs are either spherical or elongated with a uniform orientation of layers; there ...
متن کاملDauphiné twinning and texture memory in polycrystalline quartz. Part 3: texture memory during phase transformation
Samples of quartz-bearing rocks were heated above the a (trigonal)–b (hexagonal) phase transformation of quartz (625–950 C) to explore changes in preferred orientation patterns. Textures were measured both in situ and ex situ with neutron, synchrotron X-ray and electron backscatter diffraction. The trigonal–hexagonal phase transformation does not change the orientation of cand a-axes, but posit...
