Through a dip-dry-cure finishing process, these solutions were applied to cotton fabrics to achieve flame-retardant cotton fabrics DC-RmP1 (Durable and flame retardant cotton fabric prepared using flame retardant liquid RmP1), DC-RmP2 (Durable and flame retardant cotton fabric prepared using flame retardant liquid RmP2), and DC-BmRmP (Durable flame retardant cotton fabric prepared using flame retardant solution BmRmP), which were then tested and characterized. Compared with the control cotton fabric, the limiting oxygen index values of DC-RmP1, DC-RmP2, and DC-BmRmP after 50 washing cycles increased from 18.3% to 33.2%, 29.5%, and 32.3%, respectively, and all three fabrics exhibited self-extinguishing properties. The char lengths were 78, 112, and 68, respectively. Thermogravimetric analysis results indicated that the flame-retardants altered the thermal decomposition process and promoted char formation in the cotton fabrics. Cone calorimetry tests showed that the peak heat release decreased by 86.2%, 86.5%, and 80.2%, and the total heat release decreased by 85.8%, 89.0%, and 83.8%, respectively. Therefore, this work provides a green, convenient, and friendly method for producing bio-based flame-retardant cotton fabrics.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 3","pages":"472-484"},"PeriodicalIF":1.5,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic comparison of MAl-LDH formed from different divalent metal sources (M = Zn2+, Ca2+, Mg2+, Ni2+) revealed that ZnAl-LDH exhibited the most favorable morphology and performance. Despite the inherently poor conductivity of LDH materials, the specific interaction between metal hydroxyl groups (−M-OH) on the ZnAl-LDH surface and Pb2+ significantly enhanced the electrochemical response signal for Pb2+. Optimization of key parameters including supporting electrolyte, pH, enrichment potential, and time established optimal detection conditions at pH = 5.0 in 0.1 mol/L acetic acid–sodium acetate (ABS) buffer, with enrichment at −0.9 V for 230 s. Under these conditions, the electrochemical sensor demonstrated outstanding analytical performance for Pb2+ detection: a linear range of 0.4–25 μmol/L, a detection limit as low as 0.031 μmol/L (S/N = 3), along with excellent selectivity, stability, and reproducibility. Satisfactory recovery rates achieved in real-water samples further validate the sensor's practical application potential in environmental monitoring.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 3","pages":"485-495"},"PeriodicalIF":1.5,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular docking was subsequently performed with FRED, and 13 potential active compounds were successfully identified through visual inspection and structural clustering. These compounds were then subjected to in vitro biological activity evaluation, from which two active compounds, A1 and A10, were ultimately identified. Furthermore, molecular dynamics simulations were employed to investigate the binding modes between the protein and ligands in greater detail. The physicochemical properties and potential toxicity of A1 and A10 were also predicted and analyzed.

To address these challenges, carbon-based materials have been extensively studied for their ability to stabilize Zn anodes. This review presents a detailed overview of the latest advancements in carbon-based protection layers designed to prevent dendrite formation in zinc-ion batteries. It covers a range of materials, including conventional carbons, fiber-like carbons, carbon nanotubes, graphene, MOF-derived carbon layers, carbon composites, natural biopolymers, graphdiyne, and 0D carbon materials. This review also highlights recent progress in using these materials to suppress dendrite growth and reduce the formation of unwanted by-products on zinc electrodes. Additionally, this review offers perspectives on future research directions aimed at further enhancing the performance and reliability of carbon-based protection strategies for zinc-ion batteries.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 2","pages":"207-224"},"PeriodicalIF":1.5,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starch served simultaneously as a carbon source and a polymeric stabilizing agent during the synthesis. The morphology and elemental composition of the resulting nanomaterials were systematically characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Fourier-transform infrared (FTIR) spectroscopy. The Brunauer–Emmett–Teller (BET) method was applied to calculate the specific surface areas. The optical characteristics of the composites were investigated via UV–visible (UV–vis) spectrophotometry and photoluminescence (PL) spectroscopy. The findings revealed that the ZnO/carbon nanocomposite calcined at 400°C exhibited superior photocatalytic performance, achieving a 92% degradation efficiency of MO under UV light in 90 min, and 99% degradation under sunlight within 70 min. These efficiencies were approximately 2.7 and 4.2 times higher, respectively, than those obtained with ZnO/carbon treated at 200°C and pristine ZnO. The underlying photocatalytic mechanism was elucidated through radical scavenging experiments, indicating that hydroxyl radicals (·OH) were the predominant reactive species involved in the degradation process. Additionally, the photocatalytic performance of the ZnO/carbon nanocomposites calcined at 400°C was found to be strongly influenced by both the starch-to-precursor ratio and the pH of the synthesis medium.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"73 2","pages":"350-365"},"PeriodicalIF":1.5,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147566609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
