WebFeb 14, 2024 · Controlling the crystallographic registry of layered materials through interlayer twist angles has introduced a distinctive degree of freedom for tuning their … WebNov 19, 2001 · Our simulations of polymer crystallization from solutions show that (1) entropic barriers control the selection of the initial lamellar thickness, (2) growth at the crystalline interface is chain adsorption followed by crystallographic registry, and (3) lamellar thickening is a highly cooperative process requiring the mobility of all chains in …
Molecular Mechanisms of Polymer Crystallization from Solution
WebAug 8, 2024 · In crystallization, either from solution or from a melt, homogeneous nucleation is a statistical process. 29 - 31 The resulting crystals are distributed randomly all over the sample, without any correlations between these crystals. 1, 11, 18 Therefore, in order to understand how stacks of correlated lamellar crystals are generated, we need to … WebAdjacent layers are often not packed in crystallographic registry, as has been shown by electron diffraction. Multilayers of vinyl stearate 122 or some dialkyne monocarboxylic acids 123 show the so-called ‘hexagonal twinning’ that leads to a superposition of three identical diffraction patterns each rotated with respect to the preceding one ... daly city ca buffet restaurants
