Summary: This study investigated the effects of different emulsion types, oil compositions, and oil fractions on the structure and lipid oxidation in emulgel systems. It was found that emulgels were more susceptible to oxidation compared to soybean oil, with water-in-oil emulgels showing higher oxidation resistance than oil-in-water emulgels. Additionally, the degree of unsaturation in the oil composition and oil fraction had significant impacts on lipid oxidation in the biphasic emulgel systems.

Summary: This study aimed to deepen the understanding of the spray characteristics of oil-based emulsion. The spatial distribution characteristics of spray droplets of oil-based emulsion were captured visually and analyzed quantitatively. The results showed that oil-based emulsion had a special perforation atomization mechanism, leading to an increase in spray droplet size and distribution density. Nozzle configuration and emulsion concentration had significant effects on spray structures and droplet spatial distribution.

Summary: A high internal phase water in oil emulsion is used as the binder in a novel agglomeration process for selective and ultrafast recovery of hydrophobic particles. The selectivity in the agglomeration process is influenced by the solution chemistry and the pH value, while the aging of the model feed affects the agglomeration but not the flotation.

Summary: Emulsions frequently encountered in petroleum production pose technical challenges and increase costs. Chemical treatment with demulsifiers plays a vital role in destabilizing the complex emulsions, but developing effective and cost-efficient demulsifiers remains challenging. This review systematically examines the stabilization mechanisms of emulsions and categorizes demulsifiers for water-in-oil and oil-in-water emulsions, providing insights into efficient demulsification methods.

Summary: This study reports the first stable water-in-oil emulsions stabilized solely by a naturally occurring steroidal sapogenin. Concentrated emulsions with high internal water ratios can be obtained with low diosgenin concentrations, which significantly influence the microstructure and rheological properties. The emulsions exhibit excellent freeze/thaw stability and thermal stability, with the structural properties attributed to the combined action of diosgenin crystal shells and needle-crystals. This novel food grade emulsion demonstrates great potential for applications in food and biomedical-related fields.

Summary: The effect and mechanism of carrier gas velocity, V/III ratio, and carrier gas velocity match on the growth rate of AlN were investigated in this study. The results showed that the growth rate of AlN initially increased with hydrogen flow rate, reached saturation, and then decreased monotonically. The turning point value depended on the equipment and process. By increasing the MO VM, the growth rate of AlN could be improved, but the uniformity deteriorated due to turbulence and loss of uniform boundary layer. High quality AlN films were successfully grown on nano-patterned sapphire substrates with improved crystalline quality and atomic smooth surfaces.

Summary: This study investigates the melting process and nucleation behavior of sodium crystals using molecular dynamics simulation. The results show good agreement between simulated and experimental values for the melting temperature, density, and radial distribution function of sodium. The diffusion coefficient of liquid sodium increases linearly with temperature, and the homogeneous nucleation rate of melting in superheated sodium crystal exponentially increases with temperature. The findings provide theoretical support for applications involving heat and mass transfer in sodium-related systems.

Summary: Epitaxial V2O3 films were fabricated on sapphire substrates using mist chemical vapor deposition (mist CVD) method, eliminating the need for high vacuum conditions. The films can be grown on sapphire substrates even under atmospheric pressure, with the optimal growth temperature at 823 K. The films grown at 823 K exhibit a metal-insulator transition at approximately 155 K. The film on C-plane sapphire exhibits a lower transition temperature compared to those on R- and A-plane sapphire substrates.

Summary: This article discusses the novel fractal nature of hydrothermally synthesized MoS2 QDs. By adjusting the reaction time, the study found that the average size of QDs increases and then decreases with longer reaction times. STEM images indicate that shorter reaction times lead to sheet formation, while extended reaction times cause sheets to fragment into QDs.

Summary: The effect of growth temperature on the buffer leakage currents of GaN-on-Si layers was investigated. It was found that higher growth temperature results in lower leakage currents. The defects in GaN layers grown at different temperatures were studied using photoluminescence technique, and a correlation between leakage currents, structural perfection, and donor concentration in GaN-on-Si layers was established. It was also observed that reduced growth temperature leads to the formation of inversion domains.
