However, balancing permeability and rejection remains a critical challenge in membrane science and technology. Herein, we report that weak non-covalent hydrogen bonds and strong coordination bonds between ultrathin calcium silicate (UCS) interlayers and piperazine (PIP) powerfully control its diffusion. Theoretical calculations reveal that coordination bonds dominate PIP binding on UCS with an adsorption energy of −443.83 kJ mol<sup>−1</sup>, thereby impeding its movement. The diffusion coefficient of PIP diminishes by 14 % upon the incorporation of UCS, as evidenced by molecular dynamics simulations. As a consequence, a superhydrophilic, smooth, loose, and ultrathin (∼18.9 nm) PA separation layer is created. The as-obtained UCS-interlayered PA possesses a remarkable water permeance of 31.7 L m<sup>−2</sup> h<sup>−1</sup> bar<sup>−1</sup> that is 2.2-fold higher than that of UCS-free PA, while dye rejection rates keep a high level. Furthermore, the UCS-interlayered PA demonstrates exceptional antifouling performance with a 95 % flux recovery ratio and long-term stability during 16-h filtration. The study highlights the pivotal role of mineral interlayers in tailoring amine monomer diffusion via multiple interfacial interactions for advanced water treatment applications.</div></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"5 ","pages":"Article 100163"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144557142","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}

It's challenging for researchers to quickly find key information from the vast amount of publications. Large language models (LLMs) have shown promise in analyzing article and reasoning about knowledge in some scientific fields, but their effectiveness in membrane research is unclear. Here, we introduced the first benchmark specifically designed for membrane studies and used it to systematically evaluate six general-purpose LLMs (i.e., Claude-3.5, Deepseek-R1, Gemini-2.0, GPT-4o-mini, Llama-3.2, and Mistral-small-3.1). Our findings revealed that the complexity and depth of NF knowledge pose a significant challenge for these LLMs, leading to poor performance, particularly in tasks involving membrane mechanisms. To enhance LLMs' using in this field, we developed a specialized NF database and integrated it with the LLMs using Retrieval-Augmented Generation (RAG). RAG significantly improved performance across all models, with average gains of 18.5 % on Question type tasks and 10.8 % on Reasoning type tasks. Moreover, in areas such as membrane fabrication and characterization, several models with RAG demonstrated performance exceeding that of human experts. These results suggested that RAG is a promising strategy for leveraging LLMs in NF research. This study introduced a new path for applying LLMs to membrane research and proposes a professional benchmark to ensure the reliable and effective use of LLMs.</div></div>","PeriodicalId":100033,"journal":{"name":"Advanced Membranes","volume":"5 ","pages":"Article 100161"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588192","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}
