Summary: The temperature-driven genesis of morphology and structure of vanadium nanoparticle films fabricated by magnetron-based gas aggregation sources was investigated. Three temperature regions were identified, each with distinct changes in the oxidation, mass, crystallinity, morphology, and optical properties of the vanadium nanoparticles. The heating process resulted in the formation of rod-like structures and a decrease in specific surface area of the coatings, as well as a shift in the optical band gap.

Summary: This study reports the development of a new bioprobe, DPASP, for imaging bacterial extracellular vesicles (BEVs). The bioprobe can effectively label and track BEVs through its aggregation-induced emission (AIE) attribute, and outperforms commercial dyes in terms of labeling efficiency, retention time, photostability, and biocompatibility.

Summary: Using biocompatible polymers to simulate molecular crowding in vitro, this study investigates how crowding affects the morphology of lipid vesicles. The results show that moderate concentrations of sorbitol, polyethylene glycol, and Ficoll lead to the compaction of both freely diffusing and surface-tethered vesicles. Notably, the compaction caused by sorbitol is irreversible, while the effect of high molecular weight PEG-based crowders is reversible. This regulation of molecular crowding allows for precise control of vesicle architecture, with significant implications for drug delivery and vesicle trafficking systems.

Summary: This study investigates the convections developing in a gas-liquid two-phase flow using a two-fluid model, finding that convections develop in whole- or multi-layered modes when the gas injection flux exceeds a critical value. The research shows that lift forces on bubbles play a key role in the bifurcations, impeding or driving the convections depending on the level of nonlinearity.

Summary: The charring process can affect the preservation potential of seeds, and this paper investigates the changes in size, volume, and weight loss of grains under different charring conditions. The results show that temperature and exposure time directly affect the grain size, with soybean being the least affected and wheat, rice, and millet following. Volume and weight can be used to minimize bias in quantitative representation, and further experiments and comparisons of ancient samples are needed.

Summary: This study examines the global trends and regional patterns of grassland greenhouse gas balance from 1750 to 2012. It found that human management activities have caused grasslands to switch from a sink to a source of greenhouse gases, while climate change drivers contributed to a net carbon sink in soil organic matter. The net radiative forcing of all grasslands is currently close to neutral, but has been increasing since the 1960s.

Summary: This study designed and synthesized azobenzimidazole ionic liquids with reversible photo-induced conductivity regulation. The change of electrical conductivity under UV/visible light irradiation was investigated, and the effect of chemical structure and concentration of the ionic liquids on the photoresponse conductivity regulation was discussed. The results showed that UV light significantly increased the conductivity of the ionic liquid, with longer alkyl chains leading to even greater increases. Visible light irradiation returned the electrical conductivity to its initial value. The reversible photo-induced conductivity regulation was attributed to the formation/dissociation of ionic liquid aggregates induced by the isomerization of azobenzene under light irradiation.

Summary: Metal halide perovskite nanocrystals, fabricated with colloidal chemistry routes, have been shown to undergo interesting transformations when exposed to laser irradiation in liquids. In this study, transformations in large nanocrystals coexisting in different phases were induced using a femtosecond laser. The transformations included exfoliation, fragmentation, attachment, fusion, and anion exchange. The structure-photoluminescence relationships for the different samples were also analyzed.

Summary: This study explores the impact of transitioning from terrestrial livestock to marine and estuarine aquaculture on global diets, finding that aquaculture has the potential to replace meat consumption from terrestrial sources. However, harmful algal blooms (HABs) may have regional and global implications on protein supply, potentially leading to reduced protein intake.

Summary: Vanilla planifolia is threatened by water stress in many tropical countries, while V. pompona is tolerant of drought. Hybrids of these two species, such as V. planifolia x V. pompona and V. pompona x V. planifolia, show morphological and physio-chemical responses that are more resistant to water stress. Metabolomics analysis identified enrichment of carbohydrates, amino acids, purines, phenols, and organic acids in the hybrids. These hybrids are considered as potential alternatives for vanilla cultivation in the face of drought caused by global warming.

Summary: Living cells and organelles are separated by lipid membrane bilayer. By disturbing the order of the membrane, morphological changes can be induced, which can be applied to intracellular transport. DBA, a compound that undergoes photo-isomerization under visible light irradiation, has been synthesized. It has been found that DBA can modulate the lipid membrane morphology by disrupting the membrane order.

Summary: The dominant bloom-forming cyanobacterial population in Lake Taihu over the past two decades has been Microcystis. This study conducted an annual investigation of Microcystis colonies, focusing on their size, morphospecies, and viability, from 2020 to 2021, in order to understand the temporal and spatial variation in their characteristics and key environmental factors. The average colony diameter ranged from 81.12 to 499.54 μm across all sites during the investigation. The main dominant morphotypes were Microcystis flos-quae, Microcystis aeruginosa, Microcystis novacekii, and Microcystis wesenbergii, which were primarily influenced by pH, TDP, and temperature. While there was no significant correlation between colony viability and environmental factors, there were notable temporal differences in colony viability, with lower viability observed in autumn, spring, and July.
