Label exchange between BPR and Cys occurred when Cys was added to the lead(II) complex (BPR), resulting in a clear and immediate color variation from red to purple in a DMSO/MES buffer (10.0 mmol/L, pH 5.5 (1:4 v/v)). The suggested method shows a detection limit of 5.0 nmol/L and a good linear range of 0.04–4.71 μmol/L for cysteine. Moreover, based on the produced absorbance and color variation, this chemosensor is suggested as an “IMPLICATION” logic gate discussing Pb2+ and cysteine as input. As an application in molecular devices, based on such a fast and repeatable signal, a molecular-scale sequential memory unit has been designed to exhibit “keypad lock” behavior. The expanded receptor provides satisfactory reproducibility, good precision, and is used for selective determination of Cys in human blood plasma and urine. In addition, the procedure's precision was compared with the results of the suggested procedure with the HPLC method.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 3","pages":"333-347"},"PeriodicalIF":1.6,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143690263","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}

The RH-900/ZnCl2 catalyst, which is activated by ZnCl2 and produced from biomass, shows superior ORR activity compared with commercial Pt/C catalysts, with half-wave potentials of 0.89 V. Nanoparticles of ZnO and SiO2 as well as nitrogen doping, combined with the porous carbon structure, produce this improved performance. The combination enhances the ORR's active site density and enhances electron transfer efficiency. Function groups that facilitate proton transfer and structural stability are shown by Raman spectroscopy and Fourier transform infrared studies, which also show an excellent combination of ordered graphitic and disordered carbon structures and BET analysis confirms a high porous surface area of 1134.82 m2/g. Important for enhancing conductivity and catalytic activity, XPS studies reveal the existence of silicon, oxygen, zinc, and nitrogen species. FE-SEM and HRTEM analyses reveal a carbon matrix that is extremely porous and contains ZnO and SiO2 nanoparticles that are uniformly distributed. Based on the results of the electrochemical tests, RH-900/ZnCl2 is the best ORR catalyst easily accessible with superior stability and resistance to methanol poisoning compared with RH-900 and commercial Pt/C catalysts. These features placed RH-900/ZnCl2 unique as a potential long-term replacement for standard Pt-based catalysts in ORR applications within energy conversion and storage devices.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 3","pages":"306-316"},"PeriodicalIF":1.6,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689142","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}

The polyaniline molecularly imprinted polymer was made by electropolymerization of aniline in the presence of acetaminophen as a template using power supply, and then acetaminophen was separated from the polymer by solvent extraction method. Different concentrations of ACT were detected using cyclic voltammetry (CV) in water-ethanol solution, and a calibration curve with a limit of detection (LOD) and limit of quantification (LOQ) of 0.43 and 1.42 ppm, respectively, was reported along with a linear equation. The sensor showed a linear range between 5 and 40 ppm for acetaminophen detection. To investigate the selectivity of the reported sensor, a copper electrode was used to detect ACT and an ibuprofen solution was used as analyte for detection by the ACT-MIP sensor. Additionally, the nonimprinted polymer (NIP) did not show any significant peak in the presence of ACT. This sensor was able to detect acetaminophen dissolved in a real urine sample successfully. This novel sensor is prepared from polyaniline, which is a conductive polymer, and no other reinforcements are needed for the sensor's conductivity in the presence of template molecule, which in this paper is acetaminophen.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 2","pages":"229-236"},"PeriodicalIF":1.6,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389117","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}

Recovery attempts using different chemicals were also performed. Adsorption was analyzed using Langmuir and Freundlich isotherm models, and thermodynamic analyses were conducted. Fourier-transform infrared (FTIR) and scanning electron microscopy (SEM) analyses were used to investigate surface changes. The highest adsorption capacity was found for the 20% chitosan/montmorillonite composite (400 mg g−1). Temperature studies indicated a decrease in adsorption capacity with increasing temperature. Kinetic studies observed that the data fit the pseudo-second-order kinetic model better. In recovery attempts, more than 95% recovery was achieved with HNO3 and HCl. FTIR results showed that chitosan–montmorillonite interactions involved -NH, -OH, C=O, and C-O bonds, while dye binding was mainly through OH bonds. SEM analysis revealed that montmorillonite reduced surface cracks and roughness, creating a more homogeneous structure, and more rough areas appeared after dye binding. As a result, the chitosan/montmorillonite composite significantly enhanced dye adsorption capacity.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 2","pages":"196-210"},"PeriodicalIF":1.6,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389289","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}

AgNPs-infused hydrogel can offer synergistic approach for various biomedical applications, specifically in wound healing, drug delivery, and antimicrobial coatings. The incorporation of AgNPs into the hydrogel enhances their antimicrobial properties, making them ideal for reducing infections and promoting tissue regeneration. Furthermore, AgNPs-infused hydrogel can serve as controlled-release systems for therapeutic agents, which ensures sustained and targeted drug delivery. Most importantly, this type of system offers a potential pathway for overcoming the challenges posed by traditional materials.
