Summary: This study investigates the multiscale behaviors of sapphire crystal growth along different crystal directions through theoretical and experimental studies. The results show that the growth behavior of sapphire along the c-axis is more complex compared to that along the a- and m-axes, involving solid-liquid and solid-solid transformations. Moreover, an abrupt change in the interfacial structure inhibits the transformation of liquid Al2O3 into α-Al2O3 along the c-axis.

Summary: Investigating the liquid structure of yttrium aluminum garnet (YAG) at high temperatures is significant for various fields, and molecular dynamic simulations were used to study the structure of YAG within a certain temperature range and to grow a YAG single crystal. The coordination number and bond length between cations and anions changed after melting, which can be explained by Pauling's third rule. In the liquid YAG, the coordination number decreased and the main structural units were AlO4 and YO7, which provided insight into phase selection and enabled rapid growth of YAG using the Czochralski method.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
