Contamination of water by dyes can cause serious threats to aquatic systems and humankind. Therefore, water systems contaminated with organic dyes should be treated. A new cost-effective method for removing methylene blue (MB) dye using a reusable synthetic reduced graphene oxide/activated kaolin/magnetite (rGO/AK/Fe₃O₄) ternary nanocomposite was developed. The synthesis of reduced graphene oxide (rGO)-based magnetic activated kaolin nanomaterial was achieved through a simple, environmentally friendly, and single-step process. Fe₃O₄, rGO, and kaolin-based materials with distinct structures, high specific surface areas, and customizable functional groups show great potential as adsorbents. Magnetite nanoparticles (Fe₃O₄) were coated on reduced graphene oxide (rGO) nanosheets and AK surface by chemical co-precipitation method supported by ultrasonication. It is characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Fourier transform infrared (FTIR) spectroscopy to investigate the crystal structure, morphology, and functional groups present in rGO/AK/Fe₃O₄ composites, respectively. The adsorption of methylene blue dye onto the ternary nanocomposite was studied. The synthesized nanocomposite showed 66–98.2% removal of MB at pH 10, initial concentration of 15 ppm with the range of adsorbent dose 5 - 50 mg. To examine the interaction of dye molecules with the adsorbent, we employed four adsorption isotherm models: Freundlich, Langmuir, Temkin, and Dubinin-Radushkevich. The Langmuir model yielded the best fit with an R² value of 0.996 at pH 10 and 298 K. The kinetic data were analyzed with three different kinetic models at pH 10 and the linearized pseudo second-order kinetic model was found to be the best fit model for our adsorption experiment with an R² value of 0.998. Thermodynamic parameters were also evaluated. The negative values of, ΔH^o, ΔG^o and ΔS^o were calculated to be -54.8 kJ/mol, -9.91 kJmol^-1, and -150.65 J/molK at 298 K; revealing the exothermic, spontaneous, and less disordered (good adsorbent-dye affinity) process, respectively. The reusability test exhibited 98.1 % removal capacity even after the 5th cycle. Thus, the nanocomposite material showed excellent stability and reusability for removing MB dye.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"10 ","pages":"Article 100800"},"PeriodicalIF":3.8,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NiONPs were synthesized via a chemical precipitation method using nickel nitrate hexahydrate as the precursor, with iron (III) nitrate nonahydrate introduced as the dopant to achieve Fe concentrations of 2 %, 4 %, 6 %, and 8 % in the NiONPs. The resulting Fe-doped NiONPs were characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). The photocatalytic performance was evaluated by monitoring the degradation of Eosin Yellow under visible light irradiation. The characterization studies confirmed successful Fe doping in the NiO lattice, resulting in structural and compositional changes. Photocatalytic testing revealed that Fe doping enhanced the degradation efficiency of NiONPs for Eosin Yellow. Among the tested samples, 4 % Fe-doped NiONPs showed an impressive increase of nearly 30 % in degradation efficiency compared to undoped NiONPs. This enhancement is attributed to improved charge separation and increased light absorption, driven by the Fe dopant's influence on the electronic structure of NiONPs. The improved photocatalytic performance of Fe-doped NiONPs can be explained by the reduction of electron-hole recombination, which enhances the generation of reactive species responsible for dye degradation. These findings highlight the potential of Fe-doped NiONPs for applications in environmental remediation, especially in wastewater treatment processes aimed at removing organic pollutants.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"10 ","pages":"Article 100798"},"PeriodicalIF":3.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its importance in the onset and progression of cancer, USP21 has become an appealing target in anticancer drug discovery. Therefore, this study aimed to screen a collection of repurposed drugs from the DrugBank 6.0 database for possible USP21 inhibitors. At the beginning of the selection process, the library was filtered by the binding efficiency to USP21, which identified a few drug molecules with appreciable binding affinity towards the USP21 binding pocket. These shortlisted molecules were then scrutinized based on their drug profiles and biological activities, with reference to their anticancer potential. Among them, Nilotinib and Radotinib were identified as the top candidates, with higher Pa values for anticancer activity. The interaction analysis and molecular dynamics (MD) simulation study further confirmed that both Nilotinib and Radotinib bind to the important and common residues of the USP21 binding site, which may inhibit the aberrant activity of USP21 in pathological conditions. The 500 ns MD simulations showed that both drugs are capable of binding to USP21 without any significant structural changes, which justifies their likelihood of being used as repurposed agents for cancer treatment. The RMSD, <em>R</em>g, and hydrogen bond analyses showed minimal fluctuations, indicating high conformational stability. Additionally, free energy landscape (FEL) analysis supported the stability of the complexes. These results suggest that Nilotinib and Radotinib could serve as promising repurposed agents for USP21 inhibition in cancer treatment after required validation. In conclusion, the combination of docking and MD simulations highlights their potential therapeutic relevance, laying the groundwork for further development of USP21 inhibitors as anticancer drugs.</div></div>","PeriodicalId":9758,"journal":{"name":"Chemical Physics Impact","volume":"10 ","pages":"Article 100792"},"PeriodicalIF":3.8,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
