Summary: Nitrogen contamination poses a major threat to terrestrial net productivity and environmental sustainability. Anammox coupled with iron-carbon micro-electrolysis was found to significantly enhance total nitrogen removal and extend stable pH range. Free nitrous acid was identified as a critical degradation inhibitor in acid environment, while Fe corrosion helped maintain pH stability in the system.

Summary: It is observed that the ratio of nitrite consumption to ammonia consumption in Anammox systems is lower than its stoichiometry, but the reason remains unknown. This study found that the addition of Fe(OH)3 significantly decreased the ratio of nitrite to ammonia consumption in an Anammox system. The reduction of Fe(OH)3 likely served as an extracellular electron acceptor, facilitating NH4+ oxidation via Feammox pathway.

Summary: In urban inland waters in Beijing, rivers and lakes mainly act as sinks for N-2, with low carbon-to-nitrogen ratios hindering N-2 production during denitrification, while low nitrogen-to-phosphorus ratios potentially favor N-2 fixation. The study indicates that urban rivers emit negligible N into the atmosphere, contrary to the traditional paradigm of constant N loss via denitrification.

Summary: This study explored the optimal operating conditions for a sponge iron biofilter (SIBF) treating low ammonia wastewater, and found that a hydraulic retention time (HRT) of 9 h and a gas-water ratio (R) of 9:1 achieved a total inorganic nitrogen removal efficiency of 77.2%, with effluent ammonia and total inorganic nitrogen concentrations below 5 mg/L and 15 mg/L, respectively. Stable isotope tracing analysis showed that 92.8% of N2O was derived from ammonia, with nitrifier denitrification being the dominant production pathway. The microbial community analysis identified key bacteria involved in nitrogen removal in SIBF, including Nitrosomonas, Nitrotoga, Nitrospira, Dechloromonas, Thiobacillus, and Brocadia.

Summary: This study investigated the structure and function of denitrifiers and anammox bacteria in coastal sediment cores collected from Daya Bay in winter and summer, revealing depth-related variations in their activities and abundances. While denitrifiers showed higher activities and abundances in surface sediments, anammox bacteria became more dominant in subsurface sediments. The availability of electronic acceptors strongly influenced nitrogen loss activities in subsurface sediments, highlighting their role as a sink for buried nitrogen.

Summary: The study investigated the variation of nitrogen components in different aquatic ecosystems and found that nitrogen removal occurred during water flow, with a reduction rate of up to 43%. The heterogeneity in eco-stoichiometric characteristics of nitrogen components was higher in ditches and ponds compared to rivers and reservoirs. Ditches and ponds showed stronger interactions between overlying water and sediment, with higher rates of denitrification and anaerobic ammonium oxidation. The findings emphasize the importance of focusing on the upper reaches of agricultural catchments for nitrogen removal and developing region-specific conservation strategies to mitigate nitrogen pollution and protect water resources.

Iron ions, including Fe(II), Fe(III), and Fe-0, enhance nitrogen removal efficiency, accelerate electron transfer, regulate microbial flora distribution, and improve metabolic activity and secretion of extracellular polymeric substances. However, they also have negative effects, which are discussed. The paper proposes future research directions related to iron-mediated denitrification and anammox technology in wastewater treatment.

Summary: The study reveals that denitrification and anammox result in changes in nutrient stoichiometry and phytoplankton community structure in the northern Benguela, with implications for phytoplankton composition and succession in the region. Denitrification limits picophytoplankton growth, leading to a dominance of flagellates and diatom succession. The interactions between denitrification, anammox, DIC uptake and primary production highlighted in the study have significant implications for the biological pump in the northern Benguela.

The results showed that the community structure of comammox Nitrospira exhibited spatial and temporal heterogeneity, and total carbon and pH were the main environmental factors driving niche differentiation between comammox Nitrospira and canonical nitrifiers. In conclusion, three ammonia oxidizers were widely distributed in riparian wetland ecosystems around Taihu Lake, with canonical nitrifiers being more competitive and comammox Nitrospira preferring oligotrophic conditions.

Summary: Lithium-sulfur (Li-S) batteries have potential as next-generation energy storage systems, but their practical applications are hindered by slow kinetics and shuttle effects of polysulfides. This study introduces a Co/CoSe junction as an efficient catalyst for polysulfide conversion, due to its metallic electron mobility and field-enhanced catalytic activity. The junction's charge distribution rearrangement and strong interaction with polysulfides, along with the durability provided by CoSe, contribute to its high catalytic activity and long-term performance. This Co/CoSe junction offers an alternative approach for enhancing the catalytic conversion of polysulfides.

Summary: In this study, a V-intercalated NbS2 (Nb3VS6) catalyst was proposed for high-efficiency Li-S batteries. Structural analysis and modeling revealed that the undercoordinated sulfur anions of [VS6] octahedra on the surface of Nb3VS6 could break the catalytic inertness. By using Nb3VS6 as the catalyst, the Li-S batteries achieved high discharge capacities of 1541 mAh g(-1) at 0.1 C and 1037 mAh g(-1) at 2 C, and retained 73.2% of the initial capacity after 1000 cycles. This intercalation-induced high activity provides an alternative approach to building better Li-S catalysts.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
