Summary: Algae have the potential as a bio-refinery for the production of high-value natural compounds like carotenoids, which play essential roles in photosynthesis and provide diverse health benefits for humans. Advances in algal genomics and transcriptomics have improved understanding of carotenoid biosynthesis pathways in algae.

Summary: This research successfully prepared edible oil-loaded beeswax microparticles using the PGSS process with a sponge-like morphology. The size of the particles depended on whether avocado oil or Brazil nut oil was used in the formulation. The internal structure indicated that the edible oils were uniformly incorporated into the crystalline lattice of beeswax.

Summary: In this study, cinnamon and paprika oleoresins were encapsulated using spray chilling and particles from gas saturated solutions techniques, with palm oil as the wall material. The physical characteristics of the micro particles were compared, as well as their release behavior in high- and low-fat simulated food media. The spray chilling micro particles had a spherical shape, smooth surface, and passable flow property, while the particles from gas saturated solutions showed an irregular shape, porous surface, and poor flow property but higher encapsulation efficiency. Both micro particles successfully delivered the oleoresins in food products.

Summary: The g-C3N4/nano-sized ZnO (CZ) composite material was synthesized in CO2-saturated solutions, showing high surface areas for accelerated electron transport and increased catalytic active sites. The developed CZ-2 composite demonstrated exceptional efficiency of 99.9% after 25 minutes and maintained excellent stability after four recycles. This novel synthesis route may inspire the development of high-performance ZnO-based catalysts and expand the applications of ZnO.

Summary: This study compared and optimized the efficacy of different concentrations of PEG and two commercial kits for the isolation of exosomes. The results showed that a concentration of 10-20% PEG had similar size and particle concentrations compared to ExoQuick and better than TEI. Furthermore, 10% PEG was able to detect cfDNA and showed superior performance in detecting miR-122 and miR-16 expression. In addition, the proteomic results also showed better identified proteins compared to commercial kits, although there was a high level of contamination in serum. Overall, these findings highlight the importance of using an optimal concentration of 10% PEG for exosome isolation in clinical samples.

Summary: The study evaluated the effects of saturated fogging and overspray on the performance of micro gas turbines at partial loads. The results showed that power output enhancement decreased with higher loads and increased overspray ratios. Inlet fogging and overspray reduced NO concentrations and increased CO concentrations.

Summary: The study investigates the rolling motion of water droplets on hydrophobized and optically transparent micro-post array surfaces, and examines the effect of gap spacing on droplet dynamics. The results show that the gap spacing significantly influences the velocity of droplets on clean and dusty surfaces. Air trapped within the micro-post gaps acts as a cushion, reducing the contact area and increasing droplet velocity.

Summary: Polymer solutions are commonly used in the middle and late stages of reservoir development, with groundwater conditions often limiting their application. Developing salt-tolerant polymer solutions with different aggregation behaviors can facilitate the synthesis and optimization of suitable polymer systems. The impact of divalent metal cations on the properties of polymer solutions, including their aggregation behavior, viscosity, size, and rheological characteristics, was analyzed. Linear partially hydrolyzed polyacrylamide (HPAM) was found to be significantly affected by divalent cations, while hydrophobically associating polymers showed increased salt tolerance. Hydrophobically modified partially hydrolyzed polyacrylamide (HMPAM) with chain beam aggregation behavior demonstrated strong intermolecular connections, allowing it to withstand high levels of calcium and magnesium ions. Additionally, dendritic hydrophobically associating polymer (DHAP) experienced decreased viscosity and size when exposed to excessive calcium and magnesium ions, suggesting the importance of optimizing molecular weight and hydrophobic group content in constructing salt-tolerant polymer systems for high-salinity reservoirs.

Summary: This study investigates the surface charging and electrophoretic motion of PEG-rich and dextran-rich micro-droplets in different solutions. The research finds that both types of droplets are negatively charged and their electrophoretic velocities are influenced by the electric field strength. The NaCl concentration affects the velocities differently for PEG-rich and dextran-rich droplets.

Summary: The COVID-19 pandemic has restricted music activities, and this study assessed the risk of wind instrument playing in various situations. The research found that wind instrument playing produced higher aerosol emissions compared to speaking or breathing. There were no significant differences between instrumental groups, but there was high interindividual variance.

Summary: This study proposes a biocompatible method using ionic liquids (ILs) for the selective recovery of beta-carotene and astaxanthin from Phaffia rhodozyma cells. The most efficient IL solution was identified and an integrated platform for solvent recycling and biomolecule recovery was developed. The results demonstrate the efficacy of ILs for one-step extraction of beta-carotene and astaxanthin from microbial-based biomass.
