However, monochromatic fluorescence is often limited by the application environment and loses its effectiveness. Here, we carefully designed white fluorescent CDs (WF-CDs) by solvothermal method, which is used for fluorescence imaging applications under different environmental conditions. WF-CDs based on nitrogen doping can produce obvious emission peaks at 640 nm, 490 nm and 400 nm, respectively, corresponding to red, green and blue (RGB) bands in the three primary colors. The full wavelength emission was realized by changing the solvent types and pH values to adjust the emission peak intensity. WF-CDs can accurately detect Fe3+ concentration according to fluorescence extinction degree (fluorescence elimination rate reaches 95.34 %). Furthermore, WF-CDs has practical applications in cell-level fluorescence imaging, near-infrared fluorescence imaging and ultraviolet anti-counterfeiting, and has broad application prospects in the fields of nano-medicine and industrial manufacturing.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401732"},"PeriodicalIF":3.5,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143051093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce two highly crystalline, flexible COFs, ZCST-102 and ZCST-103, constructed from dual flexible monomers. These COFs exhibit large channels, permanent porosity, high chemical stability, and exceptional crystallinity, along with enhanced structural flexibility. Notably, they achieve an iodine vapor adsorption capacity of up to 4.71 g ⋅ g-1. X-ray photoelectron spectroscopy, Raman spectroscopy, and electron paramagnetic resonance spectroscopy further elucidate the interactions between iodine and the framework structures.

One of the major issues is related to high production cost, which can be overcome by designing of effective catalysts . In this study, we report the synthesis of an eco-friendly, affordable, and highly redox-active tetra-imidazole functionalized cobalt phthalocyanine (TImCoPc) through a straightforward method. The electrocatalytic performance and conductivity of TImCoPc is further enhanced by forming hybrid with highly conductive Ketjenblack (KB) in various ratios. The 3.5:1.5 (TImCoPc/KB) composite exhibited excellent HER performance, with an onset potential closer to that of Pt/C and an overpotential (η10) of -108 mV, closely approaching the η-10 of Pt/C (-36 mV). Additionally, the optimized hybrid showed a lower Tafel slope of 44 mV/dec, higher turnover frequency of 3.66 x 10-10 mol s-1 cm-2 and mass activity of 4.121 A.mg-1, with an excellent catalytic stability, thereby proving to be one of the superior electrocatalysts for HER in terms of cost, methodology, activity and efficiency. The observed enhancement in HER activity of the hybrid can be accounted to the synergistic effects that reduce the metal ion's d-band center and improve π-π interactions between the hybrid components.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401090"},"PeriodicalIF":3.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143051134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various crops the tomato plant is greatly affected by many pests such as aphids and whiteflies, which are badly decreasing tomato plant yield and effecting its growth. In last few years, various type of pesticides such as Neonicotinoids and Pyrethroids are employed which are badly effecting eco-system and water bodies. In this research work, we prepared SnO2 nanosheets (SONS) by in-situ and green synthesis approach. Remarkably, SONS exhibit a larger surface area, tailored pore size, and higher catalytic performance than SnO2 nanoparticles (SONP). To further improve the efficiency of SONS, we coupled it with covalent organic farmwork nanosheets (COFNS) via the hydrothermal approach. The SONS@COFNS hybrid nanocatalysts exhibit improved carrier migration, enhanced porosity, multiple active sites, and exceptional light absorption capabilities. The as prepared green nanomaterials delivered improved activities for Neonicotinoids and Pyrethroids degradation. Remarkably, the most active sample 6COFNS/SONS showed the highest degradation efficiency (94 %), which is approximately 1.92 times higher than the degradation efficiency of pristine SONS (49 %). This work will ultimately contribute to developing green, ecofriendly nanomaterials for pesticides degradation and promoting tomato plants growth.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401856"},"PeriodicalIF":3.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143045083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chemical structures, purity, morphology, and chemical composition were characterized through XRD, NMR, TEM, ATR-FTIR, and mass spectrometry. These hybrid nanosensors demonstrated excellent selectivity and sensitivity in colorimetric and fluorescence responses towards Hg2+, outperforming other metal ions. In their spirolactam form, the sensors were non-fluorescent but transformed into a fluorescent form upon interaction with Hg2+, resulting in enhanced fluorescence and colorimetric changes. Theoretical calculations indicated that Hg2+ could form stable complexes with the RT1 sensor by binding to the oxygen and nitrogen atoms in the spirolactam structure, as well as coordinating with the oxygen atom of the amide bond. The detection limit (LOD) was 1.68×10-7 M with a response time of less than 40 seconds.

A common treatment for hernia involves the implantation of a mesh which promotes the growth of new tissue around or within the implanted material in the damaged area. The mesh is typically made from synthetic materials like polypropylene. However, such meshes have safety concerns like biofilm and scar tissue formation, foreign body reactions, and chronic pain. These concerns gave rise to the development of biological meshes. Owing to mechanical weakness, biological meshes fail due to migration and rapid degradation. This study is aimed to develop a mechanically viable biopolymer-based composite degradable mesh. A gelatin-MWCNT composite 3D printed mesh has been developed with different pore sizes and filament sizes. Adding MWCNTs improved the composite's ductility, printability, hydrophilicity, and modulus, and reduced its degradation rate. The 3D-printed mesh also showed signs of cell attachment and proliferation representing non-toxicity of MWCNTs within the composite materials. The data showed improved cell adherence due to the incorporation of MWCNTs within the composite materials. Among the various material compositions tested, the composite material with gelatin with 0.01 g MWCNTs gave the optimum mechanical strength and biocompatibility results.","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":" ","pages":"e202401136"},"PeriodicalIF":3.5,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143045074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
