Utilizing X-ray diffraction (XRD), we established the crystalline structure, revealing crystallite sizes of 13.29 nm and 20.00 nm for Ti₃C₂ and the nanocomposite, respectively, with corresponding crystallinity indices of 60% and 70%. Scanning electron microscopy (SEM) showed that Ti₃C₂ exhibited a characteristic layered structure, while the composite demonstrated a more granular morphology with integrated ferrite particles, enhancing its magnetic properties. Energy dispersive X-ray spectroscopy (EDS) confirmed the elemental composition, including titanium, iron, barium, and chromium, validating the successful synthesis of the nanocomposite. Photoluminescence (PL) analysis indicated a significant band gap reduction from 2.05 eV for Ti₃C₂ to 1.77 eV for the composite, suggesting enhanced light absorption capabilities. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) results demonstrated impressive electrochemical performance, with a maximum specific capacitance of 728.5 F/g in 1 M H₂SO₄. These findings collectively underscore the structural integrity, enhanced electrochemical properties, and multifunctional potential of the Ti₃C₂/Fe1-xBaₓCr₂O₄ nanocomposite for advanced energy storage applications.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 2","pages":"186-195"},"PeriodicalIF":1.6,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389372","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}

However, a large number of somatic missense variations have been clinically observed to harbor in the tubulin protein, which can cause drug resistance to microtubule-stabilizing agents (MSAs), thus largely limiting the applications of MSAs in tumor chemotherapy. In this study, we created a systematic response profile of (PTX), the first approved MSA, as well as its diverse analogues (we herein termed paclitogues [PLGs]), to various tubulin variations by using an integrated in silico-in vitro (iSiV) strategy. These PLGs share a similar action mechanism and the same binding pocket with PTX, while these variations were enriched from the gene ontology (GO) network involving a variety of gynecologic cancers (GCs). A considerable difference between the ligand response profiles to α- and β-tubulin variations was observed; the former commonly has only marginal and even effects, whereas the latter generally exhibits significant but dramatically changeable responses. A number of resistant variations and few sensitive variations were identified from the profile; they can considerably reduce PTX affinity by up to ~30-fold or moderately improve the affinity by <5-fold. Multiple resistant variations can co-work in a single tubulin variant to further combat with the PTX ligand. By examining their locations in the structural architecture of tubulin protein, it is revealed that resistant variations occur either in MSA-binding pocket to directly block ligand binding or out of the pocket to indirectly impair the binding through a long-range conformational effect, while the sensitive variations promote the binding by forming additional noncovalent interactions with ligand.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 1","pages":"14-26"},"PeriodicalIF":1.6,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120207","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}

However, most MOFs still have problems such as low utilization of visible light and easy recombination of photogenerated electrons and holes. In this study, novel defective Fe-MOFs with appropriate structural defects were prepared by solvothermal method and used to remove methylene blue (MB) in aqueous phase through adsorption and photocatalysis. Defective Fe-MOFs have Fe content as high as 10.31% with specific surface area of 40.95 m2/g, which is beneficial for both dye adsorption and photocatalytic process. Defective Fe-MOFs have spindle-like structures with sizes ranging from 40 nm to 100 nm and an average size of 69.1 nm, as well as some irregularly shaped nanoparticles. Irregular stacking of these two kinds of structure makes Fe-MOFs appropriate structural defects, large specific surface area, and mesoporous structure. Kinetics and isotherms of dye adsorption process are consistent with pseudo-first-order kinetic model and Freundlich isotherm model, respectively. Defective Fe-MOFs can absorb MB dye rapidly, reaching adsorption equilibrium within 60 min. Dye adsorption process is endothermic, spontaneous, and entropy-increasing process. After 180 min visible light illumination, dye photocatalytic efficiency of the defective Fe-MOFs reaches 97.56% in the condition of MB concentration as high as 30 mg/L. Consequently, defective Fe-MOFs with appropriate structural defects, porous structure, high Fe-O content, and strong electron-donating amino groups have huge potential applications in removing organic dyes from the aqueous solution by a green and environmentally friendly way due to their high dye adsorption and dye photocatalytic activity.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 1","pages":"51-64"},"PeriodicalIF":1.6,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118984","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}

However, it is time-consuming to quantify lignin by conventional wet chemical analysis methods. In this work, a 13C multiCP/MAS NMR spectral analysis method for tobacco lignin was established. The multiCP/MAS NMR sequence was optimized for tobacco lignin. The optimized nuclear magnetic sequence parameters were 9 CP cycles of 1.5 ms, repolarization time of 0.7 s, and a total acquisition time of 130 min. Subsequently, TMSP was used as the internal standard substance to establish the working curve, and the correlation coefficient was 0.9946. The relative standard deviation (RSD, n = 5) was 3.26%. This method was applied to the determination of lignin content in different types of tobacco samples. The relative error in the determination of lignin content by this method did not exceed 4.46% compared to the results of the chemical method. The results showed that the 13C multiCP/MAS NMR spectral analysis method had the advantages of accuracy and rapidity, which provided a new technical means for the quantitative study of tobacco cell wall substances.","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 1","pages":"83-92"},"PeriodicalIF":1.6,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118755","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}
