SEM images confirmed the heterogeneous, porous, and fibrous structures favorable for sorption, while functional group modification was tracked via FT-IR. Native biomass and prepared composite were employed to optimize the pH in batch mode, while in continuous mode, parameters like flow rate, bed height, and bisphenol A concentration were optimized, and outcomes were illustrated in breakthrough curves. The maximum biosorption capacity with PH and PPY-PH is 5.17 and 6.25 mg/g, respectively, at a bed height of 4 cm and a flow rate of 1.8 mL/min. The results exhibited that the maximum biosorption capacity for PH and PPY-PH was observed at a bed height of 4 cm, a flow rate of 1.8 mL/min, and bisphenol A concentration of 45 ppm. Biosorption feasibility was also studied using mathematical models like the Thomas and Bed Depth Service Time models on experimental data. The current study revealed that peanut husk and its composite have promising biosorption potential and could be utilized in upscale wastewater treatment.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 20","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108906","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, CO2's high activation barrier and adverse reactions prevent it from developing further. Using ethylene glycol/water as a solvent, a multilayer BiOX(X = Cl, I) nanoparticle catalyst with plenty of oxygen vacancies was created in order to get over these restrictions. Furthermore, in situ Bi doping enhanced the photocatalyst's catalytic performance. The Bi/BiOX catalyst has a CO2-reduced CO yield of 31.63 µmol/(g·h), which is 1.83 times higher than the initial BiOX. The results showed that the addition of Bi enhanced the quantity of reduction sites and caused a redistribution of the surface charge of BiOX, thereby improving the efficiency of photogenerated electron capture and hastening the process of photogenerated carrier separation. By combining TiO2 and Bi/BiOX to create a heterojunction structure, the light absorption range was increased and the photogenerated carrier's separation efficiency was further improved. Bi/BiOX/TiO2 enhanced the rate of CO2 reduction to CO reduction products to 39.65 µmol/(g·h), which was 2.3 times greater than that of BiOX (17.29 µmol/(g·h)). The yield and selectivity of CO2 reduction to CO are shown to be improved by in situ Bi doping in this work, offering a fresh approach to the creation of effective photocatalysts.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 20","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108791","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}

External validation with a test set confirms the models' capability to accurately predict the activity of newly designed compounds within the applicable range, achieving an accuracy of 78%–84%. The models were used to perform a virtual screening of a chemical library for compounds expected to be active against Acinetobacter baumannii.

Ach. led to the isolation of four compounds (1–4). Among these, 9,11-dehydroergosterol peroxide (3) demonstrated the most substantial anti-inflammatory effects both in vitro and in vivo using zebrafish models. Molecular docking studies were conducted to assess the binding affinities of the selected compounds with important inflammatory mediators iNOS and IL-10, and molecular dynamics (MD) simulations were performed on the most potent anti-inflammatory compound. RMSD plot analysis indicated that 3 remained stable throughout a 200 ns simulation period, particularly with iNOS. RMSF plots also suggested a stable and well-fitted conformation of 3 within the binding site of iNOS. The complex stability during the simulation is attributable to the hydrophobic interactions of 3 with TRP463, which contributed over 40% to the protein-ligand interactions. These findings suggest that 9,11-dehydroergosterol peroxide (3) could be a promising new strategy for treating inflammation.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 20","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/slct.202406180","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, NiO nanocrystals were successfully synthesized using four different concentrations of NaOH (0.5, 1.0, 1.5, and 2.0 M), yielding samples designated as NiO-A, NiO-B, NiO-C, and NiO-D, respectively. The structural and morphological characteristics of the synthesized samples were thoroughly investigated. Among them, NiO-A exhibited superior crystallinity, as confirmed by X-ray diffraction (XRD) analysis. Field emission scanning electron microscopy (FESEM) revealed that NaOH concentration significantly influenced the morphology of the nanocrystals. X-ray photoelectron spectroscopy (XPS) analysis confirmed the presence of Ni in the + 2-oxidation state in NiO-A. Electrochemical performance was evaluated through cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). NiO-A demonstrated the highest specific capacitance of 165 F/g at a scan rate of 5 mV/s, attributed to its large Brunauer–Emmett–Teller (BET) surface area of 462 m2/g, pore volume of 0.49 cc/g, and low charge transfer resistance of 65.13 Ω. Additionally, GCD analysis revealed an energy density of 3.2 Wh/kg at a power density of 1870 W/kg, highlighting NiO-A's potential as a promising electrode material for high-performance supercapacitors.","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"10 20","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108793","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}
