Summary: This study investigated the interaction between coal particles in aqueous solutions using experiments and molecular simulations. The results revealed the self-aggregation behavior of lignite and anthracite at different coalification levels. The adhesion force between particles was found to be an important factor, with lignite having a higher surface electrostatic potential and providing more polar regions for water adsorption. The dispersion interaction, dominated by 7C-7C interactions, promoted cluster formation and stability. The study also observed a decrease in the number of surrounding water molecules and a change in water molecule orientation, affecting the flocculation efficiency of coal particles in slime water.

Summary: This study explores the influence of humic acid (HA) corona on the aggregation kinetics of different-sized nanoparticles (NPs) in water environments. It is found that the repulsive force from the hydration layer affects the aggregation processes of NPs, with smaller NPs being more affected. HA corona impedes aggregation by playing a steric hindrance role in monovalent solutions, while in divalent solutions, it goes through three stages for larger NPs and two stages for smaller NPs. The interaction between HA and NPs is mainly influenced by the aromatic ring of NPs and the carbonyl groups of HA. This study provides valuable insights into the combined effects of HA corona and particle size on the aggregation kinetics of NPs.

Summary: In this study, a set of parameters for all-atom simulations of HPβCD based on the ADD force field for sugars is proposed, which shows considerably improved prediction of HPβCD self-association and interaction with water compared to the original CHARMM36 description. The simulations further reveal pronounced interactions of HPβCD with both polar and nonpolar moieties, particularly with the aromatic rings of tyrosine, phenylalanine, and tryptophan. Additionally, a preferential orientation of HPβCD's hydrophobic cavity toward the backbone atoms of amino acids suggests a propensity for HPβCD to denature proteins.

Summary: Raspberry is rich in bioactive compounds, such as phenols, anthocyanins, and flavonoids, that provide protection against non-communicable diseases. This study examined the effects of hydrogen peroxide, salicylic acid, humic and fulvic acids, glutamic acid, and seaweed extracts on the bioactive compound content and agronomic parameters of raspberry plants. The results showed that hydrogen peroxide increased flavonoids, anthocyanins, omega 3, and oleic acid content, while salicylic acid increased flavonoids, anthocyanins, and citric acid content in raspberry fruits. The use of humic and fulvic acids, glutamic acid, and glutamic acid combined with seaweed extracts increased flavonoids and anthocyanins content without affecting plant growth and fruit yield. Glutamic acid and seaweed extracts also increased palmitic acid and DEG;Brix content in fruits.

Summary: This study investigates the effect of cation exchange resin (CER) on the sequential recovery of hydrogen and methane from anaerobic digestion (AD) and the corresponding mechanisms. The results show that CER can simultaneously enhance the production of hydrogen and methane by promoting the solubilisation, hydrolysis, and acidification of organic matter. Additionally, CER facilitates effective contact between bacteria and organic particulates and reduces the energy barrier for mass transfer during methane production. The study also reveals changes in the microbial community structure and metagenomics during the AD process.

Summary: The fouling of seawater reverse osmosis membranes is a persistent challenge in desalination. This study monitored the operational performance of a desalination plant for 7 years and the fouling development in different areas of membrane modules. The findings showed that operational performance declined over time and fouling mainly occurred at the feed side of the modules, with the highest microbial diversity. Keystone species like Chloroflexi and Planctomycetes played an important role in maintaining community structure and biofilm maturation. Polysaccharides, soluble microbial products, marine humic acid-like substances, and inorganic substances contributed to fouling. Overall, biofouling had a significant impact on membrane fouling after 7 years of operation.

Summary: By synergizing organic carbon source, thiosulfate, and zero-valent iron, efficient mixotrophic denitrification of oligotrophic secondary effluent can be achieved. Thiosulfate plays a vital role in promoting TN removal efficiency, while corrosion of Fe0 releases OH- to neutralize H+ from thiosulfate-driven denitrification, creating a suitable environment for denitrification. The coordination of thiosulfate and Fe0 maintains the dominance of Thiobacillus for denitrification.
