They accumulate in various environmental components, leading to contamination of water, soil, and air, which adversely affects ecosystems and human health. In the current study, a new set of 3-benzyloxy aniline-derived Schiff bases have been synthesized. Various spectroscopic techniques, including 1H and 13C NMR, IR, TGA, and mass spectrometry have been used to characterize the synthesized Schiff Bases, 4(a-d). Among them, 4c demonstrated exceptional selectivity and sensitivity for Al(III) characterized by a color change from colorless to pale yellow with a detection limit of 14.2 × 10−8 M. Metal, complex of 4c and Al(III) has been synthesized and characterized using (1H and 13C) NMR, FT-IR and mass spectrometry. Compound 4c was assessed for its efficacy against aluminum toxicity in Vigna radiata (Mung bean) and exhibited significant results in promoting plant survival under extreme metal stress. The potential biological applications of Schiff Base, 4c were investigated through in-silico studies targeting the protease enzyme pathway, which is crucial for the replication, survival, and various cellular functions of the dengue virus. The findings revealed a low inhibition constant of 383.45 nm and a high binding energy of −8.75 Kcal mol−1, suggesting that ligand 4c may serve as an effective inhibitor against the dengue virus.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726785","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 investigation focuses on key performance metrics including hardness, water absorption, flammability, thermal stability, and overall composition. By incorporating recycled cellulose paper, these tiles not only contribute to reducing environmental waste but also support a circular economy in the construction industry. The results demonstrate that these eco-friendly tiles exhibit a significant increase in hardness (20 HCR units higher than commercial tiles), a reduced water absorption rate of approximately 13%, and good ignition resistance up to 284 °C, enhancing their durability and fire safety. Advanced analytical techniques, including Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR), confirm the effective integration of cellulose fibers within the tile matrix, leading to a homogeneous chemical distribution. Statistical analysis further validates that these sustainable tiles outperform conventional materials in key performance areas. The findings emphasize the transformative potential of cellulose paper composition in creating sustainable, high-performance roofing materials.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717422","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 electronic properties, including HOMO (−5.209 to −5.294 eV), LUMO (−1.458 to −1.483 eV), and energy gaps (3.734–3.811 eV), were calculated. Compounds with lower energy gaps, such as C4 (3.734 eV), exhibited higher reactivity due to enhanced electron-donating ability. Global hardness (1.867–1.906 eV) and softness (0.262–0.268 eV⁻¹) further confirmed stability trends. Electron transfer (ΔN: 1.770–1.790) and back-donation energies from (−0.467 to −0.476 eV) indicated strong inhibitor-metal interactions. Monte Carlo simulations revealed adsorption energies ranging from −143.821 to −184.859 kcal/mol, confirming spontaneous adsorption. C10 demonstrated the highest adsorption energy (−184.859 kcal/mol) indicating superior stability and inhibition efficiency. The systematic addition of ─CH3 groups influenced electronic properties and adsorption behavior, with longer alkyl chains enhancing hydrophobic protection and electron-donating effects. The dipole moment values of the studied compounds (C1–C10) increase significantly from the gas phase to the aqueous phase (DMSO) indicating enhanced polarity and improved solubility in polar solvents. This study provides insights into designing effective corrosion inhibitors and highlights the utility of computational methods in predicting their performance.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717286","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}

But carbon recycling is difficult, thus recyclable adsorbents are advantageous. In this context, SBA-15/propyl-NH2 was synthesized, characterized, and used to adsorb food dyes (brilliant blue, allura red, tartrazine) in water. The removal effectiveness (%) of adsorbent was examined considering pH, dose, concentration, time, and temperature. The mechanism of adsorption was examined using pseudo-first- and pseudo-second-order kinetics. Langmuir, Freundlich, and Temkin isotherms were used to evaluate adsorbent-adsorbate interactions. The thermodynamic parameters (∆G°, ∆S°, and ∆H°) were evaluated and compared. Langmuir adsorption isotherm showed monolayer adsorption for all dyes with R2 values around 1. With rate constant (k2) of 0.0003 to 0.0013 g/mg min, the kinetics followed pseudo-second-order model. The adsorption capacity of SBA-15/propyl-NH2 for tartrazine, brilliant blue, allura red was estimated at 403.22 mg/g, 395.25 mg/g, 485.43 mg/g respectively. Adsorption occurs with a decrease in free energy, a negative enthalpy, and a decrease in entropy at 25 °C. The adsorbent recyclability was confirmed over three cycles, with no reduction in removal effectiveness (%). Therefore, the SBA-15/propyl-NH2 nanocomposite effectively separates food and textile dyes from water-based solutions.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 13","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143717379","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}
