This study clarifies the linkage between polymerization phenomena and catalyst deactivation in HG-AOPs employing carbon materials. We demonstrate that the deposition of polymerization products leads to a self-inhibition effect by maintaining a consistent polymerization energy barrier, regardless of the increasing degree of polymerization (DP). This consistency facilitates the persistent formation of high-DP products. Using machine learning analysis, we reveal that higher DPs intensify hydrophobic interactions and van der Waals forces, which promote the robust adhesion of polymeric products to the catalyst surface. These adherent layers compete with oxidants for active sites, impeding oxidant adsorption, obstructing electron transfer and ultimately hindering further catalytic activity. Additionally, we evaluate several catalyst-regeneration methods from a sustainability standpoint. This work contributes to developing sustainable strategies for effectively utilizing carbon-based nanomaterials in water treatment, offering a foundation for future innovation in HG-AOPs. Catalyst deactivation commonly occurs in heterogeneous catalytic advanced oxidation processes, but the mechanisms are not well understood. This study finds that catalyst deactivation is closely related to deposition of polymeric products of the pollutant-removal process.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"178-190"},"PeriodicalIF":0.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The relative stability of climate and water resources over the past millennia allowed humans to build complex societies with established agriculture, infrastructure and economies that today sustain the livelihood of eight billion people. As the planet warms, this steady state of water movement is being altered, and both oceanic and terrestrial components of the global water cycle are undergoing measurable changes that will probably continue. Predicting the new trajectory of Earth’s water in a warming climate begins with observing the entire water supply–demand chain across the planet, from Earth’s largest water reservoir, the ocean, to water storage, use and recycling on land. A recently launched space observatory, called the Surface Water and Ocean Topography (SWOT), is making a timely entrance and addition to the water-observing networks, by providing direct, high-resolution measurements of the water height and volume of nearly all water on the Earth’s surface. Here we link technological advances in wide-swath satellite altimetry and SWOT’s novel measurements of water volume across the planet to scientific innovations for Earth’s water cycle, including studies of changes in the water storage and dynamics in global lakes and rivers, rising seas, ocean energetics and land–ocean exchange, with implications for practical information for water resource managers and climate resilience efforts. We also discuss how SWOT innovations set the stage for future missions and integrated Earth-system approaches within the water science community. The new SWOT satellite mission tracks global water supply–demand and land-to-ocean water movement, leading the way towards an integrated satellite observatory that can help humanity adapt to Earth’s shifting water and energy systems.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 1","pages":"27-37"},"PeriodicalIF":0.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past decade, substantial advancements have been made in improving both solar-to-steam conversion efficiency and long-term stability. However, relying solely on solar conversion efficiency as a performance benchmark is no longer sufficient, given the widespread achievement of high efficiency levels. Exciting progress has recently been made in the functionalization of SSG, suggesting a new and pivotal role for SSG in addressing broader application scenarios related to water and energy sustainability. In this Review we first trace milestones in the development of SSG and explore its conceptual functionalization, which is driving recent innovative strides in water and energy sustainability. Insights are provided to further exploit this promising potential. Finally, we discuss the challenges and future prospects of SSG, highlighting a pathway for future development and practical applications.

However, the long-term drivers of change in surface water storage, particularly those related to anthropogenic activities, remain unclear. Here we use multi-mission remote sensing data to construct monthly time series of water storage changes from 1985 to 2020 for 105,400 lakes and reservoirs in global drylands. An increase of 2.20 km3 per year in surface water storage is found primarily due to the construction of new reservoirs. For lakes and old reservoirs (constructed before 1983), conversely, the trend in storage is minor when aggregated globally, but they dominate surface water storage trends in 91% of individual global dryland basins. Further analysis reveals that long-term storage changes in these water bodies are primarily linked to anthropogenic factors—including human-induced warming and water-management practices—rather than to precipitation changes, as previously thought. These findings reveal a decoupling of surface water storage from precipitation in global drylands, raising concerns about societal and ecosystem sustainability. This study quantifies and attributes the changes of surface water storage in global dryland basins over 1985–2020, indicating that long-term changes are mainly linked to anthropogenic factors rather than precipitation.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 1","pages":"80-88"},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44221-024-00367-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143121645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional methods for nitrogen and phosphorus removal face limitations in terms of energy consumption, operational complexity and environmental impact. Here we develop a floc management strategy to integrate anammox and enhanced biological phosphorus removal (EBPR) processes in a single-stage hybrid system (biofilms and flocs). This integrated approach resolves the conflicts between anammox and EBPR processes concerning ecological niche and solid retention time, enabling ultraefficient nitrogen and phosphorus removal efficiencies of 97.7 ± 1.3% and 97.4 ± 0.7%, respectively, in low-carbon municipal wastewater treatment. Notably, anammox benefitted from substrate competition with endogenous denitrification (both nitrite and nitrate) with floc loss, resulting in a significant enrichment of anammox bacteria in biofilms (12.5%) under mainstream conditions. Meanwhile, controlling floc concentrations at around 1,000 mg l−1 could maintain low polyphosphate levels in flocs, effectively addressing the additional phosphorus removal burden imposed by the enrichment of phosphorus-accumulating organisms in biofilms. This work offers a transformative solution to the long-standing challenge of integrating anammox and EBPR, paving the way for more sustainable and energy-efficient nutrient removal in wastewater treatment. The enhanced removal of nitrogen and phosphorus is realized by floc management in an integrated system of anammox and enhanced biological phosphorus removal.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"201-210"},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the application of lithium extraction from salt lakes, membranes dominated by size sieving and Donnan exclusion typically enhance Li+/Mg2+ selectivity by sacrificing Li+ flux, which inevitably increases the energy consumption of the separation dramatically. In this work, we manipulate the pore charge density to demonstrate the important role of counterion-mediated positively charged channels in efficient Li+ transport. The potential relationship between the transport behaviour of cations and the membrane charge density was revealed after decoupling the transport of anions and cations using the electric field. On the basis of Manning’s counterion condensation theory and density functional theory calculations, the transport mode in monovalent cations by interacting with the anchored counterions in the positively charged pores to form a high-velocity transport pathway is revealed. The cationic covalent organic framework membranes displayed high Li+/Mg2+ selectivity of 321 in electrodialysis tests while possessing superior lithium permeation rates (0.53 mol m−2 h−1). Therefore, our results suggest that counterion-mediated covalent organic framework membranes have great potential in the field of lithium resource extraction. The counterion-mediated positively charged channels in covalent organic framework membranes enable the fast transport of lithium ions, realizing high lithium/magnesium selectivity without compromising lithium ion flux.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"3 2","pages":"191-200"},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
