Here we report a geometry-engineered Janus electrospun membrane that integrates asymmetric wetting with structural design to suppress salt buildup. The membrane combines a hydrophobic carbon black–polystyrene photothermal layer for broadband solar absorption and localized heating with a hydrophilic polyacrylonitrile transport layer and a cotton scaffold ensuring continuous capillary water supply. A systematic comparison of nine geometries fabricated from the same membrane reveals that evaporator geometry governs heat localization, ion transport pathways, and salinity tolerance. Among different configurations, an inverted-cone architecture exhibits exceptional durability, sustaining evaporation fluxes of 1.03–1.36 kg m⁻² h⁻¹ and solar thermal conversion efficiencies of 70%–92% under 1-sun illumination in 3.5 wt% NaCl without visible salt deposition for over 4224 h. These findings reveal macroscopic geometry-controlled ion transport as a key design principle for scalable, salt-resistant solar evaporation.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"28 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report the direct design of a novel indium-MOF-derived In2O3/InVO4–YFeO3 (InYFe) dual Z-scheme multijunction using a simple wet-chemical strategy to address these limitations. The physicochemical properties of the ternary InYFe heterostructure were systematically investigated using advanced characterization techniques. Notably, the InYFe-4 catalyst exhibited outstanding photocatalytic degradation efficiency toward diclofenac (DCF), attaining 99.5% degradation in 60 min, significantly outperforming the single and binary components. The improved photocatalytic activity is primarily ascribed to the generation of an internal electric field at the heterointerface, the prolonged lifetime of photogenerated charge carriers, and the preservation of sustainable active sites via multichannel Z-scheme charge transfer. Furthermore, radical quenching experiments and electron paramagnetic resonance analyses reveal that h+, O2•−, and •OH act synergistically during the photocatalytic elimination of DCF. Integrating theoretical simulations with experimental findings, the degradation pathway of DCF under photocatalytic conditions were comprehensively elucidated. This study contributes to the rational development of MOF-derived Z-scheme multijunction photocatalysts for addressing emerging organic contaminants.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"24 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AI agents, which use large language models to plan and execute multi-step tasks, could automate it, yet how an agent should be organised is unknown. Using a controlled Storm Water Management Model (SWMM) calibration case study, we compared three organisations of the same procedures: written instructions consulted when needed (skill-based), fixed interfaces supplied in advance (tool-based), and specialised agents each responsible for one stage (multi-agent). All three completed the workflow and produced calibrated models of equivalent accuracy, so they differed in the reliability and cost of reaching that result. Consulting instructions on demand sustained longer sequences of requests but required a more capable language model, whereas supplying interfaces in advance was least expensive and suited single tasks but became unreliable once the task was extended. Dividing the work among agents remained reliable at a cost that varied with the language model. No single organisation was best on all counts, so the choice depends on the length of the task, the capability of the available language model and the acceptable token consumption. These complementary strengths indicate where each organisation is appropriate, and a complete calibration workflow could combine them, each applied to the stage it suits, offering a practical route towards agent-supported urban drainage modelling.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"92 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149010466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we quantitatively investigate bacterial physiological responses to PAW under nutrient-rich conditions using colony-forming unit (CFU) counting and nanomotion sensing. CFU measurements reveal complete bacterial inactivation at high PAW concentrations, confirming its strong antimicrobial activity. However, intermediate concentrations induce increased bacterial proliferation compared to nutrient-matched controls, indicating enhanced physiological activity under sub-lethal exposure. Nanomotion sensing independently confirms this biphasic response, showing increased oscillatory activity at intermediate concentrations and complete signal suppression at bactericidal levels. These measurements provide real-time, single-cell evidence of concentration-dependent physiological modulation. The observed response is consistent with adaptive activation under moderate reactive species exposure and inactivation at higher concentrations. These findings quantitatively demonstrate that bacterial interactions with PAW are not limited to monotonic inhibition but involve a broader physiological response landscape. These results further demonstrate that nanomotion sensing can rapidly quantify antimicrobial thresholds and detect subtle physiological responses to plasma-derived reactive species. This provide new insights into microbial responses to PAW, and may help optimizing plasma-based antimicrobial applications.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"494 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To overcome this, a large body of research has focused on chemically modifying existing hydrophobic membranes. While chemical modification of polyvinylidene-difluoride (PVDF) membranes by fluoroalkyl silanes improves resistance to mineral scaling, it involves multiple steps, harsh chemicals, and offers only marginal improvement. In this study, we present the possibility of engineering anti-scaling surfaces by tailoring the top membrane layer during non-solvent-induced phase separation (NIPS) itself. Contrary to common perception where scaling resistance mandates a rough superhydrophobic surface, our comparative studies reveal that PVDF membranes with a relatively smooth surface and low pore size effectively deter gypsum scale adhesion over other NIPS strategies. The same also outperformed commercial PVDF membranes of different average pore sizes (0.45 µm and 0.2 µm). Overall, while NIPS can be tailored to fabricate PVDF membranes with diverse morphologies, our findings demonstrate that using water as the non-solvent yields a membrane surface on which gypsum scales exhibit weak adhesion, allowing most deposits to be readily washed away.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"24 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to characterize a group of chlorine-tolerant Klebsiella pneumoniae species complex (KpSC) isolates based on antimicrobial resistance genes (ARGs), phylogenetic relationships to clinical strains, and other genomic traits associated with pathogenicity. Sewage samples collected from various wastewater treatment plants in Alberta, Canada, were treated with chlorine bleach at doses sufficient to reduce coliform bacteria by 4 log10 (i.e., 99.99% reduction), yielding 21 chlorine-tolerant KpSC isolates. Comparative genomics was used to characterize these chlorine-tolerant KpSC isolates against publicly available genomes from clinical and non-clinical KpSC strains. Chlorine-tolerant KpSC isolates belonged to 15 different sequence types and included Klebsiella pneumoniae, Klebsiella quasipneumoniae, and Klebsiella variicola, which are among the most common and clinically relevant KpSC phylogroups. Phylogenetically, chlorine-tolerant isolates from sewage were genetically diverse, clustering with clinical genomes according to species and sequence type, and reflecting significant strain diversity. Of the 21 chlorine-tolerant sewage isolates, eight resolved into a clade with one or more exclusively clinical genomes. Six isolates differed by < 80 single nucleotide polymorphisms from at least one clinical isolate, implying high genetic similarity to clinical strains. Virulence gene profiles were also remarkably similar, albeit the resistomes of the chlorine-tolerant sewage isolates lacked many relevant ARGs frequently detected in related clinical genomes. Collectively, these data suggest that chlorine-tolerant KpSC sewage isolates may be clinically important.","PeriodicalId":19375,"journal":{"name":"npj Clean Water","volume":"144 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
