Summary: The artificial tidal wetlands ecosystem is effective in treating saline water and contributes significantly to global nitrogen cycles. This study operated seven experimental tidal flow constructed wetlands to remove nitrogen from saline water at different salinities. The study identified multiple microbial processes involved in nitrogen loss and found that nitrogen assimilation by plants accounted for 6.9-23.4% of the total nitrogen transformation.

Summary: The effects of plant root activities on different microbial nitrogen transformation processes in the rhizosphere of constructed wetlands have not been comprehensively studied. This study investigated the N removal performance and transformation processes in the rhizosphere using various methods. Results showed that nitrification was promoted, denitrification was inhibited, and both anammox and DNRA processes were found to be inhibited in the rhizosphere. This study provides better insights into the biogeochemical cycle of N in the rhizosphere of constructed wetlands.

Summary: This study investigated the effects of aquatic macrophyte debris on nitrogen removal and microbial communities in constructed wetlands. The addition of plant debris did not change the average removal efficiency of ammonium (NH4+-N) and total nitrogen (TN), but showed significant differences over time. The decomposition of plant debris released NH4+-N and organic nitrogen, which affected nitrogen removal and increased denitrification activities.

Summary: The study found that using intertidal wetland sediments as a microbial source for CWs can effectively improve phosphorus removal rates, with bacteria such as phosphorus-accumulating organisms enhancing microbial transformation of phosphorus. However, the addition of IWS increased phosphorus loss via substrate accumulation and decreased phosphorus removal rate via plant uptake.

Summary: This study investigated the role of root exudates released by macrophytes in nitrogen removal in constructed wetlands (CWs). The results showed that Myriophyllum aquaticum released root exudates at a higher rate compared to other plants, and the release rate was influenced by ammonium concentration and harvesting frequency. CWs with plants showed higher ammonium removal efficiencies than those without plants, while there was no significant difference for total nitrogen removal. The microbial community composition in sediments was slightly different between root exudate and no-root exudate treatments. The study suggests that adding high levels of root exudates can enhance nitrogen removal in CWs for carbon-limited wastewater treatment.

Summary: The study investigated the impact of coastal embankments on nitrogen cycling in Spartina alterniflora salt marshes. The results showed that the embankments significantly reduced nitrogen storage and concentrations in both plant and soil subsystems. However, the effects varied seasonally, with some nitrogen subpools increasing while others decreased. The establishment of embankments decreased soil salinity, leading to increased ion uptake by microbes and subsequently stimulating microbial biomass production.

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.
