Growth morphologies of crystal surfaces
Physical Review A, 1991A previously proposed Monte Carlo model (Xiao et al., 1988, 1990) is extended to three dimensions, and reevaporation after accommodation and growth on dislocation-induced steps are included. It is found again that, for a given set of growth parameters, the critical size beyond which a crystal cannot retain its macroscopically faceted shape scales ...

Crystal Morphology and Crystal Symmetry
2003Crystallography grew up empirically as a branch of mineralogy. It was supported by laws deduced from observations, such as the law of constancy of interfacial angles and the law of rational intercepts, and involved mainly the recognition, description, and classification of naturally occurring crystal species, that is, it was a study of the morphology ...

Engineering Crystal Morphology
Annual Review of Materials Research, 2013Crystallization is an important separation and particle formation technique in the manufacture of high-value-added products. During crystallization, many physicochemical characteristics of the substance are established. Such characteristics include crystal polymorph, shape and size, chemical purity and stability, reactivity, and electrical and ...

Morphologies of CVD ZrC Crystals
Physica Status Solidi (a), 1981Particulate ZrC crystals of well-defined morphologies are formed by chemical vapor deposition from the ZrBr4–CH4–H2–Ar system. The basic forms are considered to be the prisms of 〈110〉axis having rhombic, pseudo-rhombic, and trigonal cross sections, which are bounded with four {111}, two {111} and two {110}, and two {111} and one {100} side faces ...

Morphology of Oligomer Crystals
Proceedings, annual meeting, Electron Microscopy Society of America, 1973Poly(ethylene terephthalate) (PET), contains approximately 1.5% oligomer (cyclic trimer). When films are heated the oligomers tend to migrate out and crystallize on the surface. The isolation and identification of oligomer has been reported; the crystal structure has been studied by x-ray and electron diffraction. Except for some optical work, however,

Calcium oxalate crystal morphology
Trends in Plant Science, 2002Plants invest considerable resources of carbon and calcium in crystal formation, indicating that it is an important basic process in growth and development. The diversity of crystal shapes, as well as their prevalence and spatial distribution, have led to several hypotheses regarding crystal function in plants.

Quantification of crystal morphology
Journal of Crystal Growth, 1994Abstract Morphological measurement constitutes an important experimental subject in crystal growth and materials science, and is currently receiving renewed attention because of the rapid advances occurring in computer technology, coupled with the concomitant sharp reductions in the cost of digital image processing.

The morphology of anthracene crystals
Journal of Crystal Growth, 1967The prominent faces of anthracene single crystals grown from solution or from the vapour are those which correspond to planes with small reticular areas. The basal plane is usually dominant with the {110}, {101}, {111}, {112}, and {201} planes occurring to varying degrees depending on the mode of growth.

Dehydration of nigeran crystals: Crystal structure and morphological aspects
Journal of Molecular Biology, 1979Abstract The crystal structure of anhydrous nigeran, poly[(1 → 3)-α- d -maltose], obtained from Penicillium crustosum has been determined by a combined electron diffraction. X-ray diffraction and packing analysis. The electron diffraction pattern from solution-grown single crystals shows some (h k I) reflections in the baseplane pattern.

Morphology of melt-crystallized syndiotactic polypropylene
Journal of Electron Microscopy, 2002A transmission electron microscopy (TEM) study was made to investigate the mechanism of isothermal crystallization from melt for syndiotactic polypropylene (sPP) with a syndiotactic pentad fraction of 0.92. The TEM morphologies of RuO4-stained and ultrathin-sectioned specimens revealed a clear assignment of lamellar crystals with different crystal ...
