In the thermal equilibrium of the two mesophases a faceted rectanglelike shape was observed with considerably different shape anisotropies for the three homologs. Various morphologies such as dendritic, dendriticlike, and faceted shapes of the rapidly growing smectic-B germ were also observed for the three substances. Experimental results were compared with computer simulations based on the phase field model. The pattern forming behavior of a binary mixture of two homologs was also studied.10 p.application/pdfeng(c) The American Physical Society, 1996Cristal·lografiaSòlidsLíquidsEquacions d'estatTransformacions de fase (Física estadística)Interfícies (Ciències físiques)Ciència dels materialsCrystallographySolidsLiquidsEquations of statePhase transformations (Statistical physics)Interfaces (Physical sciences)Materials scienceinfo:eu-repo/semantics/article109304info:eu-repo/semantics/openAccess
