Summary: In this study, europium-doped sodalite phosphors (Na-8(AlSiO4)(6)(Cl)2:Eu3+) were successfully synthesized using kaolin through hydrothermal and roasting processes. The factors affecting the synthesis of the samples were investigated, and the crystallization, morphology, and luminescence intensity were analyzed. The obtained Na8(AlSiO4)6(Cl)2:Eu3+ phosphors showed good crystallinity and emission intensity, making them promising for application in LED lamps that require excitation of the ultraviolet chip.

Summary: The study aimed to fabricate metallic glassy materials with high thermal stability and glass-forming ability, which were then consolidated into bulk metallic glasses. The results showed that the microhardness of the synthesized metallic glassy alloys increased with an increase in tungsten concentration, and very large bulk metallic glassy buttons were successfully fabricated in this study.

Summary: To obtain crystal products with ideal morphology and better quality, it is important to understand the affecting mechanism of solvents on crystal morphology. This study investigates the interactions between solvent/solute molecules and different crystal faces of pyriproxyfen through experiments and molecular simulations. The results reveal that the choice of solvent affects the crystal morphology, with methanol and ethanol leading to lamellar crystal growth, while n-butanol and n-heptane leading to three-dimensional shuttle crystal growth. The findings provide insights into the growth mechanism and can contribute to the optimization of pyriproxyfen crystal products.

Summary: The 2D population balance model (2D PBM) provides enhanced capability for modeling two different growth kinetics, particularly for needle-like particles in crystallization processes. While the 1D PBM is useful for optimization, it cannot accurately match particle size quantiles or investigate particle aspect ratio changes, highlighting the necessity of the 2D PBM in pharmaceutical industry applications to minimize particle aspect ratio.

Summary: This study found that different film morphologies can be obtained through different liquid crystalline (LC) phase transition processes. Films rapidly cooled from the melt exhibited higher crystallinity, while films slowly cooled exhibited higher lamellar packing. The LC phases and annealing programs are important for morphology design.

Summary: This study investigates the use of natural polymer additives, including ethyecellulose, hydroxy propyl cellulose, hydroxypropyl methyl cellulose, and sodium lignin sulfonate, to modify the crystal form and morphology of clozapine crystals. The type of additive has a clear effect on crystal morphology, while the dosage of additive greatly affects the average particle size of the crystals. The study also explores the mechanism of natural polymer additives on morphology regulation through molecular simulation.

Summary: Crystal morphology is influenced by several physicochemical parameters including temperature, pressure, cooling rate, nucleation, diffusion, volatile composition, and viscosity. Crystallization is a two-stage process involving nucleus formation and ion accumulation. The shape of crystals depends on undercooling (ΔT), and euhedral crystals grow just below their liquidus temperature. This study investigated and characterized crystal morphologies in different minerals in silicic volcanic rocks (spherulites) and ancient mining slags, which exhibited subhedral, skeletal, dendritic, spherical, bow-tie and fibrous forms depending on the cooling rate.

Summary: Multimodal multiscale characterization techniques are used to study organic semiconducting thin films and reveal crystallization mechanisms of different microstructures. The observations show the hybrid crystalline structures in rubrene thin films and the transition to a spherulite morphology. The importance of considering the initial temperature increase during thermal annealing is discovered, and it is found that thermal conditions can significantly affect the crystallization of organic thin films.

Summary: In this study, dairy phospholipid gels were made with varying concentrations of PL to investigate their gel-forming ability and functional properties. Results showed that high concentrations of PL reduced mobility and increased solid fat content, melting enthalpy, and viscosity. Oil binding capacity was significantly affected by PL concentration, indicating that dairy PL can be used to produce semi-solid material with desirable functional properties when added to vegetable oil.

Summary: This study investigates the effect of incorporating a second comonomer unit in the crystalline unit cell on the melt memory effect of a major component in a random isodimorphic copolymer. It is found that even small amounts of the second comonomer unit significantly reduce the melt memory effect of the copolymers. This reduction is attributed to the disruption of intermolecular interactions and the reduction in self-nucleation capacity caused by the incorporation of the second comonomer unit in the polymer chain.

Summary: Zeolites W were prepared by hydrothermal method and ion-exchanged to H-formed catalysts. The aging step prior to crystallization strongly affected the crystal morphology and Si/Al atom ratio of zeolite samples. The H+-exchanged zeolite crystals with longer aging time exhibited better catalytic activity, possibly due to the low Si/Al ratio and higher acidity.

Summary: This study investigates the effects of particle shape on the collapse of granular columns using the discrete element method. The results show that particle shape has a significant impact on deposition morphology, energy evolution, and mechanical coordination number. Sphericity and angularity are identified as the most important macroscale factors, while roughness has a weaker microscale influence.
