Summary: Natural organic matter (NOM) extracted from Sphagnum peat soil self-organizes into colloidal aggregates of variable sizes in water, stabilized by the exposure of polar functional groups to solvent, forming hydrogen bonds and dipole interactions. The inner part of the aggregates displays hydrophobic features and is further reinforced by p-stacking interactions.

Summary: By integrating two-dimensional lead halide perovskites with plasmonic nanoparticle arrays, we have established an open and versatile exciton-polariton platform, where excitons hybridize with surface lattice resonances in the strong coupling regime. We directly observed enhanced exciton transport and demonstrated an improvement of exciton migration by more than one order of magnitude. We proposed a polariton-mediated exciton transport model and obtained an average polariton velocity of approximately 1 x 10^6 m/s for states with a photonic fraction of about 40%.

Summary: Catalysis is a highly complex phenomenon involving fundamental processes on multiple length scales. The understanding of the full-scale complexity of catalysis is still limited, and the experimental documentation of how atomic-scale processes influence long-range order in materials is lacking. Elucidating the link between atomic-scale structural dynamics and collective behavior could lead to a deeper understanding and further optimization of catalysts and processes.

Summary: The study investigated the influence of two sources of natural organic matter on the behavior of nanoplastics, finding that NOM could reduce the aggregation and sedimentation of NPs, showing excellent stabilization effect. The stability effect was affected by NOM concentrations and sources. Pedogenic NOMs caused stabilization effect through adsorption modes with different microscopic morphologies, while BSA induced stabilization through steric stabilization.

Summary: A fluorescent sensing platform of bisphenol A (BPA) based on enzymatic oxidation-mediated fluorescence quenching of silicon nanoparticles (SiNPs) is established for the detection of BPA in food. The SiNPs emit bright green fluorescence and BPA can be oxidized by horseradish peroxidase (HRP) and hydrogen peroxide (H2O2) to quench the fluorescence of SiNPs. The method shows a good linear relationship between fluorescence intensity and BPA concentration with a low limit of detection (LOD) of 0.69 μM.

Summary: This comprehensive survey investigated the occurrence, bioaccumulation, and trophic magnification of parabens and their metabolite 4-HB in a marine food web. Results showed that parabens were the predominant pollutants in marine organisms, with significant bioaccumulation from sediments. The estimated trophic magnification factor indicated biomagnification for MeP and trophic dilution for 4-HB. Overall, the risks for humans consuming marine organisms were found to be low.

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: Hydrodynamic processes play a crucial role in the transmission of sediments, microbial assembly, and organic carbon redistribution in the ocean. Through experiments and analysis, we found that hydrodynamics shape the assembly of microbial communities and control the redistribution of different sourced organic carbon, thereby influencing microbial-mediated biogeochemical transformation.

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: This study implemented a microaerobic-aerobic configuration in a full-scale municipal wastewater treatment facility and investigated the effects on sludge characteristics, pollutant removal, microbial community, and granulation mechanisms. The results showed successful transition from flocculent-activated sludge to well-defined AGS after two months of operation. The primary pathways for pollutant removal were simultaneous nitrification, denitrification, and phosphorus removal. Moreover, the incorporation of internal separators induced shifts in the flow pattern, which promoted granulation.

Summary: Efficient anaerobic digestion relies on the cooperation of different microorganisms with different metabolic pathways. This study investigated the effects of different operational modes and the addition of powdered activated carbon (PAC) on ethanol metabolic pathways. The results showed that the SBR mode and the presence of CO2 facilitated ethanol metabolism towards propionate production, while the CFR mode with extended solids retention time enriched Geobacter. Adjusting operational modes and PAC addition can modulate anaerobic ethanol metabolism and enrich Geobacter.

Summary: This study analyzed the occurrence and distribution of antibiotic resistance genes (ARGs) in different environmental media of the Yangtze River using metagenomics. Core resistome dominated by multidrug resistance genes was found in all samples, while rare resistome dominated by various resistance genes was more prevalent in plasmids. Specific bacteria were identified as hosts for both core and rare resistomes, with high clinical concern ARGs found in the rare resistome. Particle-associated environment provided the most ideal conditions for resistome hosts. This study provided insights into the genetic locations of ARGs and the community assembly mechanisms of ARG hosts in freshwater environments.

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.
