Despite the increasing per capita use of antimicrobials in Australia, surveys remain limited. Here we investigated the occurrence and use of 102 antimicrobials and their transformation products in raw wastewater collected from 50 wastewater treatment plants across Australia, encompassing ~50% of the national population. The wastewater data were subsequently correlated with catchment-matched Census data to identify population-level socioeconomic factors associated with antimicrobial use. The results showed the detection of 41 antimicrobials and 15 transformation products, covering most of the common antimicrobial groups, with 30 analytes detected at a frequency >50%. Amoxicilloic acid and cephalexin occurred at the highest concentrations and population-normalized mass loads. Correlation analysis revealed a significant association between the consumption of antimicrobials and various socioeconomic statuses, including income, education, occupation, housing, race, health condition and transport. Our study offers comprehensive insight into the patterns of antimicrobial use at the population level in Australia and highlights potential socioeconomic drivers of its use. The use of antimicrobial agents can exacerbate the proliferation of antimicrobial resistance genes, which can put public health at risk; evaluating this risk requires proper monitoring. An extensive investigation of Australian wastewater reveals a distinct correlation between the type of antimicrobial used and the socioeconomic status of the population.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1166-1177"},"PeriodicalIF":0.0,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845210","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}

Integrating a conventional flat two-dimensional (2D) membrane with structures of different dimensionalities is expected to create additional water transport sites. However, organizing the membrane building blocks into a mixed-dimensional hierarchy capable of facilitating rapid water transfer, while also enabling large-scale, cost-effective manufacturing, remains a significant challenge. Here we report the discovery of rapid self-organization of large-area mixed-dimensional polyamide membranes with an intriguing hierarchical structure consisting of one-dimensional nanotubes on a 2D nanofilm under room temperature using only two types of small molecules at an oil–water interface. The resulting architecture with one-dimensional nanotubes on a 2D nanofilm offers a substantially increased available area for water transport per projected area, enabling energy-efficient nanofiltration membranes with outstanding water–salt separation performance that well surpasses most state of the art membranes. Control experiments, coupled with molecular dynamic simulations, reveal that the two types of molecular monomers self-organize into a 2D nanopore network during the incipient reaction stage and then capillarity within these nanopores drives the upwards polymerization of these nanotubes. Our findings provide valuable insights into how the interplay of interfacial physical and chemical interactions organizes molecular seeds into large-scale, complex hierarchical nanostructures under ambient conditions. This opens new opportunities for developing scalable, mixed-dimensional water purification membranes. Polyamide membranes with a hierarchical structure consisting of one-dimensional nanotubes on a two-dimensional nanofilm can deliver energy-efficient nanofiltration with outstanding water–ion separation performance. This architecture provides a promising approach to the synthesis of scalable and efficient mixed-dimensional water purification membranes.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1238-1248"},"PeriodicalIF":0.0,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845246","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}

However, existing water disinfection technologies are often not only energy and chemical intensive but also inefficient at eliminating antibiotic resistance genes (ARGs). Here we show a sequential electrochemical process of ‘chemical (H2O2 pre-treatment)–physical (nanotip electroporation)–chemical (•OH injection)’ that is highly effective in inactivating ARB and removing ARGs. The bacteria are first pre-treated by H2O2 generated via two-electron water oxidation in the SnO2−x/TiO2 anode region to reduce the defences of bacterial outer walls against electroporation. Then, the ‘softened’ and ‘weakened’ bacteria are easily punctured by electroporation in the Pd-Au/TiO2 cathode region and by synchronously injected abundant •OH generated via three-electron oxygen reduction. Bacterial inclusions, including nuclear body and cytoplasm, are effectively decomposed by •OH oxidation, resulting in the destruction of the entire cell structure from the inside out. This bactericidal mechanism of synergetic physical damage and chemical oxidation inactivated >99.9999% of ARB and removed ~99% of ARGs at short retention time (~16 s), high flux (~4.5 m3 h−1 m−2) and low energy consumption (~42.4 Wh m−3) over 15 days of continuous operation. This approach may act as an alternative to meet the urgent need for efficient and residue-free water disinfection. Zhang et al. present a sequential electrochemical process that enables synergetic physical damage and chemical oxidation of antibiotic-resistant bacteria and antibiotic resistance genes, providing an efficient and residue-free water disinfection approach.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1226-1237"},"PeriodicalIF":0.0,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845157","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}

Here we introduced the curvature parameter as a new variable for designing high-performance CDI electrodes. On the basis of a comprehensive surface curvature/electric field model, we found that smaller surface curvature radii may result in higher-concentration ion distributions. As a typical experimental example, bicontinuous mesoporous polypyrrole with saddle-shaped high-curvature surfaces demonstrated an enhanced ion docking effect, which provided high salt adsorption capacity values of 262.7 mg g−1 at 1.2 V and 312.5 mg g−1 at 100 mA g−1, along with an ultra-long cycling life of over 2,000 cycles. This CDI performance surpassed those of all previously reported CDI electrodes. This study provides a new design paradigm based on curvature structural engineering for next-generation CDI materials and demonstrates a promising approach for developing large-scale and sustainable high-performance CDI devices. A design principle based on the curvature parameter provides important guidance for the design of capacitive deionization electrodes.","PeriodicalId":74252,"journal":{"name":"Nature water","volume":"2 12","pages":"1195-1206"},"PeriodicalIF":0.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142845255","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}
