WebMorphology of polymers 195 given P and T in case of infinite extension of the phases, may become the stable one as the sizes are reduced. As limitation in size is one manifestation of morphology, we see here a link between thermodynamics and morphology through the concept of metastability, and underlying all, with the kinetic … WebResults: The morphology predicted by the two models is approximately consistent. The morphology predicted by AE model was in good agreement with the morphology of crystals grown from solution. The main crystal faces {002}, {101}, {011} and {012} were observed in the morphology predicted by AE model.
WebAug 28, 2024 · Crystals have high symmetry, all having four 3-fold or four 3 axes. Some have three 4-fold axes as well, and some have 2-fold axes or mirror planes. Cubes and octahedra are examples of forms belonging to the cubic system, but other forms belong to the cubic system, too.
