Molecular docking studies have been conducted to predict the binding between organic peroxide and certain biological targets, such as the breast cancer receptor 3hb5-oxidoreductase and the prostate cancer mutant 2q7k-Hormone. The docking results indicate potential interactions between peroxide and these targets. In addition to its potential cytotoxic activity, organic peroxide has been investigated for its antidiabetic activity. The docking results suggest that peroxide binds to the active site of enzymes involved in diabetes, such as α-amylase, pancreatic lipase, and β-glucosidase, with low binding energies. This indicates a potential role for peroxide in the treatment of diabetes. Furthermore, the interaction between peroxide and the antioxidant protein IHD2 (2HCK) has been explored. These computational studies suggest a possible pharmacological role for peroxide in the treatment of Helicobacter pylori (H. pylori) infection. The docking energy between peroxide and Helicobacter pylori adhesin HopQ type I bound to the N-terminal domain of human CEACAM1 indicates that peroxide could be a potential target to inhibit H. pylori infection. It’s important to note that these findings are based on computational methods and molecular docking studies.

Based on the above background, in this article, a new supramolecular compound named o-[C20H18N2O4][Mo8O26]0.5.H2O was obtained through hydrothermal method by reacting 1, 2-bis[4-nitrile-pyridine)-N-methylene]phenyldibromide (L1) with (NH4)6Mo7O24.4H2O. The compound was characterized by IR, PXRD, and single crystal X-ray analysis. Single crystal X-ray analysis shows that the compound consists of a [β-Mo8O26] 2–, a dicarboxylic acid chelating ligand and a water molecule. This compound exhibits good catalytic activity towards MB. The degradation rate of MB by photocatalysis of compound 1 was 75.2% .

This study aims to assess the photocatalytic capabilities of Mn doped ZnO nanocomposites in degrading methylene blue (MB) dye under ultra-violet light exposure. This study details the synthesis of ZnO photocatalysts through a straightforward one-step sol-gel method, incorporating varying levels of Mn-doping (0%, 2% & 4%). The structural and optical attributes were examined using techniques such as powder X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and UV-Vis diffuse reflectance spectra. X-ray diffraction analyses verified the presence of a hexagonal wurtzite crystal structure in all synthesized samples, exhibiting a high degree of crystallinity. In addition, an investigation into the impact of Mn impurities on the photocatalytic performance of ZnO catalysts was conducted in the context of methylene blue (MB) degradation. The experimental findings revealed that the Mn doped ZnO nanoparticles produced exhibited significantly superior photocatalytic performance compared to pure ZnO when used in breaking down methylene blue under UV-light exposure. This study proposes that these Mn doped ZnO could serve as a highly effective photocatalyst for treating water contaminated with certain chemically persistent synthetic organic dyes. The improved photocatalytic capabilities of ZnO nanostructures doped with Mn were ascribed to the synergistic impact of increased surface area in ZnO nanosphere and enhanced efficiency in charge separation resulting from optimized Mn doping. A potential explanation for the heightened photocatalytic performance of Mn-doped ZnO nanostructures is proposed tentatively.","PeriodicalId":18027,"journal":{"name":"Main Group Chemistry","volume":"57 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139266984","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}

Reactive extrusion is used to crosslink peroxide and combine it with polypropylene (PP).

Other additives are added to PP in addition to stabilization in order to enhance or change certain of its properties. With the addition of varying levels of organic peroxide [2,5-Dimethyl-2,5-di (tert-butyl peroxy) hexane]. The use of peroxide in the manufacturing process of polypropylene is a method of breaking in the polymer chains, which can affect its properties, including its MFI. It is possible that increasing the amount of peroxide used leads to a higher degree of branching or cross-linking, which in turn leads to a higher MFI value. However, it is important to note that the relationship between the amount of peroxide used and the resulting MFI values may not be linear and may depend on other factors as well. In addition to the MFI, other properties of the polypropylene were also measured, including shear and melt flow index, melting and crystallization temperatures, flexural and tensile moduli, and yield stress. These properties are important for understanding the mechanical and thermal behavior of the polymer and can be used to optimize its performance for specific applications.","PeriodicalId":18027,"journal":{"name":"Main Group Chemistry","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135721769","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 results of thermochemical parameters display the interaction of the DBT with BNNS is a spontaneous and exothermic process. The UV/Vis absorption analysis was carried out to predict the changes that occurred during the adsorption of the DBT upon the BNNS. Based on the FMO analysis, the value of the energy gap (Eg) of the BNNS reduced after the interaction of the DBT with the BNNS. The negative value of ΔN (-0.0048) of the DBT@BNNS complex confirms the charge transfer from DBT to the BNNS which is inconsistent with the results of the NBO analysis. QTAIM analysis displays an electrostatic interaction between BNNS and DBT. According to the results of NICS calculations, after the interaction of DBT with BNNS, all three rings A, B, and C of DBT have become more aromatic and stable in the presence of the nanosheet magnetic field.
