Bacterial and chemical contaminants found in river water pose risks to human health and aquatic ecosystems. The study initially compared the effectiveness of CC to uncoated coir (UC) treatment in removing bacterial pathogens. CC treatment demonstrated superior removal efficacy compared to UC treatment. For samples with a bacterial concentration of 3.6×103 CFU/mL, CC treatment achieved a removal rate exceeding 90% and viability losses of over 60% for E. coli and over 90% for S. aureus. As the number of bilayers increased, the regrowth potential of bacteria decreased, leading to mortality rates of ∼ 97% for S. aureus and 65% for E. coli respectively. Furthermore, the superiority of CC over UC in removing emerging contaminants were demonstrated. CC attained removal efficiencies of over 99% for isoniazid, 95.08% for lidocaine, 95.21% for mefenamic acid, and 87.73% for caffeine. The reproducibility of the CC system was tested and showed stable removal efficiency over multiple cycles. These findings highlight the potential of CC systems as effective eco-friendly alternatives for water purification to remove bacterial pathogens and emerging contaminants.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"4 ","pages":"Article 100045"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000229/pdfft?md5=092521f2f758e22efa58ec60ad2b4b8e&pid=1-s2.0-S2949823624000229-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140947782","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}

In this paper, we demonstrate the fabrication of a self-supported heterostructured nanoarray electrocatalyst, namely, NiTe/Ni<sub>2</sub>P, which exhibits exceptional performance and durability in the OER in alkaline seawater conditions.

We studied the molecular cognition and underlying mechanism for phytopathogen control provoked by HTL-AP via multiscale analysis including mycelial morphology, intracellular metabolites and transcriptome.

Life Cycle Assessment (LCA) has been widely employed to evaluate the environmental impacts associated with LIBs recycling. However, a comprehensive synthesis of the lessons learned from these assessments, including methodological choices, findings, and implications, is lacking in the literature. Therefore, this study aims to summarize the available knowledge on the application of LCA for LIBs recycling. This study uses a systematic literature review method in combination with structured content analysis to identify and analyze 64 peer-reviewed LCA studies on LIBs recycling. The key findings reveal significant variations in potential impact results and divergent results regarding the environmental preference among the available recycling processes (hydrometallurgical, pyrometallurgical, direct recycling, and bioleaching). These discrepancies arise from different assumptions and methodological choices in LCA, including variations in system boundaries, inputs, the inclusion or exclusion of specific stages, unit process and flows, assumptions regarding the use of avoided products, functional units, impact assessment methods, and the use of secondary data due to the lack of primary data, especially on an industrial scale. While the Climate Change category receives considerable attention, other impact categories are often neglected, making it challenging to establish the environmental preference of a particular recycling technology. For direct recycling and bioleaching technologies lack assessments for all impact categories. Electricity consumption and chemical inputs are identified as hotspots for all recycling options. To enhance the sustainability of LIBs recycling, additional studies that focus on collecting primary data, particularly for the collection, pretreatment, and final disposal stages are recommended. To improve the transparency and reproducibility of future studies, this article provides recommendations and a research agenda for conducting LCA studies in the field of LIBs recycling.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"3 ","pages":"Article 100032"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000096/pdfft?md5=882cc9867d21d8022e2b8c6bb30f045a&pid=1-s2.0-S2949823624000096-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140160112","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}

Therefore, this paper reviews the latest understanding of BECCS. The key findings reveal the limitations of current models in projecting the capacity and costs of bioenergy with carbon capture and storage (BECCS), mainly due to insufficient consideration of ecological consequences, including availabilities of biomass and difficulties in the transportation of biomass and CO<sub>2</sub>. To reduce uncertainties in the capacity and costs of BECCS, it is urgently needed to apply spatially explicit method for estimating the life-cycle emissions and the complete cost items when deploying BECCS, optimize the network of biomass acquisition, power plants retrofitting and transportation of biomass and CO<sub>2</sub>, and represent the changes in the availability of biomass (for different types of bioenergy plants) under the impacts of climate change. This paper emphasizes the gap between the potential capacity of BECCS and the demand for BECCS that is needed to achieve the climate goals. Suggestion on policy interventions is provided to accelerate the application of BECCS from the aspects of economic tools, regulatory tools, and information tools. Deployment of BECCS could be accelerated to halt the rapid rise of global annual average temperature and reduce the risk of carbon lock-in from fossil-fuel supply infrastructure. As BECCS could play a key role in achieving ambitious climate targets, it is important to maintain a balance between environmental, social, and economic considerations in the Earth system under a high sustainability of development.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"4 ","pages":"Article 100040"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000175/pdfft?md5=d077000d9624f2aa34caa12c42bb0a4e&pid=1-s2.0-S2949823624000175-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140879743","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}
