X-Ray diffraction was used to measure the size of the CuO nanoparticles. CuO nanoparticles can be recycled and used again after the reaction course. The ADMET analysis and drug-likeness results indicated that indole derivatives satisfied Lipinski’s principles and drug-likeness requirements. The reactivity indices and potential areas obtained from the FMO experiments were successfully used to a range of molecular systems because they yield valuable information. Here, we determined the oxobutanoate derivative’s critical areas and likely reactivity directions.

The method is based on the formation of an ion-pair complex between metoclopramide and cobalt(II) thiocyanate under acidic conditions (pH = 3), followed by DLLME to efficiently preconcentrate the chromogenic complex. In the novel DLLME procedure, methylene chloride was used as the extraction solvent and acetonitrile acted as the dispersive solvent, generating a cloudy heterogeneous mixture upon injection into the aqueous sample. This facilitated extensive interfacial contact and partitioning of the metoclopramide-cobalt complex into the fine dispersed methylene chloride droplets within minutes. After centrifugation, the sedimented organic phase was analyzed at the maximum wavelength of 625 nm. Under optimal conditions, the method permitted quantification of metoclopramide from 0.25–45 µg/mL with high enrichment factors, and LOD of 0.078 µg/mL, LOQ of 0.258 µg/mL and high extraction recoveries in the range of 94–101% were obtained. The proposed DLLME-spectrophotometric methodology provides a simple, rapid and sensitive approach for routine therapeutic monitoring and quality control of metoclopramide in real samples.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"94 9","pages":"2517 - 2528"},"PeriodicalIF":0.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540576","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}

This article introduces a nanocontainer designed to bind and neutralize paraquat. The nanocontainer is a nanoscale sphere created through microemulsion polycondensation of resorcinarenes with tyrosine and carboxylate groups and phenylboronic acid. Transmission electron microscopy and dynamic light scattering indicate that the average size of the nanocontainer is approximately 300 nm. Fluorescence and NMR spectroscopy show that the nanocontainer binds paraquat, resulting in a shift of proton signals towards higher fields and fluorescence quenching, with a binding constant of 28000 M−1. This interaction alters the electrochemical properties, contributing to toxicity. In the cyclic voltammetry analysis of paraquat, adding the nanocontainer after three reduction cycles eliminates the reduction peaks, indicating complete neutralization of paraquat. The article details the nanocontainers synthesis, physicochemical properties, binding efficiency of paraquat, and its impact on electrochemical behavior, as well as potential applications for mitigating paraquats harmful effects.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"94 9","pages":"2310 - 2320"},"PeriodicalIF":0.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540743","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}

A chirped-pulse amplification setup and a grating-based device are presented that can be used to amplify a chirped pulse with a total gain of up to 1011. A typical block diagram of a chirped-pulse amplifier for producing high-power femtosecond pulses is described. The use of an amplifying system consisting of a multipass amplifier and amplification stages with a progressive increase in the diameter of the laser beam makes it possible to increase the pulse energy by a factor of 108–109, avoiding damage to the amplifying elements. The method of amplifying chirped pulses requires the use of diffraction gratings with sizes close to 1 m to amplify pulses up to energies of tens of J. In particular, the use of giant laser systems based on amplifying cascades containing neodymium glass plates is noted. A parametric method for amplifying femtosecond pulses is considered. The advantages and disadvantages of parametric amplification are discussed. A general block diagram of an installation for obtaining petawatt-level femtosecond pulses by parametric amplification is presented. The principle of parametric amplification is used not only to obtain ultra-high powers and intensities, but also to achieve high values of other parameters.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"94 9","pages":"2538 - 2544"},"PeriodicalIF":0.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142540580","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}
