The presence of MPs in the aquatic environment is reported to have serious potential environmental and health impacts. Therefore, it is essential to develop efficient and sustainable strategies for the remediation of MPs from the aqueous environment. Traditional techniques for the remediation of MPs from an aqueous environment have limitations, including high costs and the production of secondary pollutants. In this scenario, bioremediation offers several advantages and has emerged as a cost-effective, eco-friendly, and efficient strategy for the removal of MPs from water. This article critically reviews the recent progress in the applications of bioremediation for the removal of different MPs from water. The effects of key factors such as the characteristics of MPs, environmental conditions, and types of microorganisms on the removal of MPs are elaborated in detail. The underlying mechanisms involved in the removal of MPs by microorganisms are also discussed comprehensively. Major technological challenges are identified, and recommendations for future research are provided. Despite several challenges, bioremediation is a promising approach that can revolutionize the MP removal process if the major challenges are addressed.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141531598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Few studies have explored the nexus between water use and economic output from the enterprise perspective. This study focuses on the metallic and non-metallic mineral products sector, quantifying the nexus between water consumption and economic output at the enterprise level, analyzing the heterogeneity of water consumption elasticity of economic output across different regions and sub-sectors, and identifying key sub-sectors within each region that are highly dependent on water consumption. The results indicate that for the metallic and non-metallic mineral products sector, a 1% increase or decrease in water consumption leads to a corresponding increase or decrease in economic output by 0.096%. Water consumption elasticity of economic output varies from 0.056 to 0.131 according to the regions. And it ranges from 0.048 to 0.104 for different sub-sectors. This study identifies regions and sub-sectors where economic output is highly dependent on water resources.

Herein, a critical spatial-isolation strategy is demonstrated to separate the originally adjacent lithium metal and separator for higher safety and stability of lithium metal batteries by designing a Janus carbon fabric (CF) anode. Transferring lithium from the anode/separator interface to CF bottom shuts down the prerequisite of lithium dendrite formation, while the oversized lithium at CF bottom can be also used to compensate for the loss of lithium during the charge-discharge cycling. As a result, the Janus CF//Li anode exhibits an ultralong cyclic life of 450 h at 2 mA cm<sup>−2</sup> and &gt;250 h at 4 mA cm<sup>−2</sup>, which significantly exceeds the common CF//Li anodes. Full cells coupling the Janus CF//Li anodes demonstrate longer cycle life (550 cycles) than that of the CF//Li anodes (450 cycles) at 1C, along with higher rate capability, and excellent cyclic stability at 2C. The remarkable results, as a proof of concept, signify the superior anode structure for improving both battery safety and cyclic stability for the realistic application of lithium metal batteries.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141532570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
