Summary: Here, a facile and selective synthesis of cationic azatriphenylene derivatives was achieved through electrochemical intramolecular cyclization, where the key step involves atom-economical C-H pyridination without a transition-metal catalyst or an oxidant. This proposed strategy provides a practical approach for introducing cationic nitrogen (N (+)) into pi-electron systems, thus expanding the molecular design of N (+)-doped polycyclic aromatic hydrocarbons.

Summary: In this study, CeO2-based porous carbonaceous frameworks (CeO2 PCFs) were used as antioxidant nanozymes to scavenge reactive oxygen species and absorb benzo[a]pyrene. CeO2 PCFs exhibited excellent superoxide dismutase-like and catalase-like activity, effectively eliminating superoxide radical, hydroxyl radical, and hydrogen peroxide. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) free radical scavenging assay confirmed the free radical scavenging ability of CeO2 PCFs. Furthermore, CeO2 PCFs with large surface area and porous structure efficiently adsorbed benzo[a]pyrene. The designed CeO2 PCFs can serve as new antioxidant nanozymes for scavenging reactive oxygen species and adsorbing polycyclic aromatic hydrocarbons (PAHs).

Summary: Polycyclic aromatic hydrocarbons (PAHs) are a common pollutant in marine environments, with negative impacts on ecological systems and human health. This study investigated the use of a modified willow-derived biochar to enhance its structure and prevent the desorption of phenanthrene (PHE). The results showed that the modified biochar effectively removed PHE from solution. Application of the biochar to PHE-polluted marine sediments also reduced the bioavailability and toxicity of PHE.

Summary: This study investigates the microbial interactions in organic matter decomposition (OMD) and the influence of environmental factors on microbial interactions in river ecosystems. The researchers use cotton strip as a substitute for organic matter in the Luanhe River Basin in China. The results show that bacteria and fungi cooperatively form an interaction network to achieve the decomposition of cotton strip. The key modules in the network, mainly composed of Proteobacteria and Ascomycota, are identified as the effective decomposers. Water temperature and total nitrogen are dominant environmental factors positively influencing the decomposition process.

Summary: This study investigated the transport of microplastic-oil-dispersant agglomerates (MODAs) in a simulated ocean system and explored related mechanisms under different conditions. It was found that heavy oil-formed MODAs mainly stayed at the seawater surface, while light oil-formed MODAs were distributed throughout the seawater column. Increased salinity promoted the transport of certain MODAs, and minerals facilitated the sinking of large microplastic-formed MODAs. The study proposed a MODA-mineral system and recommended Rubey's equation for predicting sinking velocity.

Summary: This review examines the interaction between microplastics/nanoplastics and co-existing contaminants, such as organic contaminants, potentially toxic elements, and metal/metal-oxide nanoparticles. The characteristics of the plastics, including polymer type, size, functional groups, and weathering, influence their combined effects with the co-existing contaminants. Mixture toxicity is not only affected by these factors, but also by the type of contaminants, their concentrations, exposure time, dissolved organic matter, and surfactants. Different organisms show different responses to the complex system. Organic contaminants can be biodegraded, which may enhance or alleviate mixture toxicity. Potentially toxic elements can be adsorbed and desorbed under changing environments, further affecting the combined effects. The presence of metal/metal-oxide nanoparticles is more complicated, as some particles may release ion metals, increasing the contaminant composition.

Summary: This study found that the presence of elemental sulfur (S0) in sulfidated zero-valent iron (S-ZVI) can enhance the removal of Cr(VI) and improve recyclability when compared to FeS or iron polysulfides (FeSx, x > 1). The formation of micro-galvanic cells, the semiconductor properties of cyclo-octasulfur S0 with Fe2+ substitution, and the in situ generation of highly reactive iron monosulfide (FeSaq) or polysulfides precursors (FeSx, aq) were identified as the reasons for this improved performance. The interaction between S0 and ZVI required direct contact and overcoming the spatial barrier caused by FexSy formation.

Summary: This study is the first to investigate the effects of freeze-thaw (FT) and microplastics (MPs) on the distribution of antibiotic resistance genes (ARGs) in soil aggregates. The results showed that FT increased the relative abundance of ARGs in different aggregates by promoting the growth of intI1 and ARG host bacteria. However, polyethylene MPs hindered this increase caused by FT. The study also revealed that FT, MPs, and their integration promoted the proliferation of human pathogenic bacteria in soil aggregates.

Summary: The transition in the energy mix has increased the need for accurate emissions reporting in the petroleum supply chain. Current carbon footprint assessments lack resolution and traceability, leading to poor visibility into carbon intensities in crude oil trading. Through the use of high-fidelity datasets and optimization algorithms, this study reveals significant variability in carbon intensities at the level of crude trade pathways. By prioritizing low-carbon supply chain pathways, additional CO2-equivalent savings can be realized.

Summary: Micro-nano metal-organic framework (MIL-68(Fe)) and a MIL-68(Fe)/chitosan composite sponge (MIL-68(Fe)/CS) were successfully prepared for efficient adsorption of azo anionic dye Congo red (CR). The MIL-68(Fe)/CS showed faster adsorption kinetics and easier desorption than MIL-68(Fe). The adsorption process of MIL-68(Fe)/chitosan composite sponge on CR is a complex physicochemical process, influenced by factors such as pH, contact time, adsorbent dosage, initial solution concentration, and temperature. The removal rates and adsorption capacity of CR by MIL-68(Fe)/chitosan composite sponge reached high values, and the synergistic effects of different interactions contributed to the CR removal.
