Results showed organic residue capping on CuO nanoparticles varied based on the extract and capping medium used. The thermal stability of all CuO samples was observed to be high, as recorded from TGA patterns and confirmed by EDX analysis, which showed a high content of copper ranging from 10.1 to 36.1%. TEM analysis revealed an average particle size of less than 20 nm for all six samples, suggesting a similarity in size. The soaking technique produced the most stable bio-capped CuO nanoparticles with a high negative zeta potential value. According to the study, the CuO samples synthesized from aqueous extracts obtained through soaking showed the highest antibacterial activity. This could be attributed to the high oxygen ratio, which was confirmed via EDX analysis. The bio-capped CuO was effective against multidrug- resistant gram-positive bacteria MRSA, and C. albicans. A mechanism was proposed to explain how the capping media affected the antimicrobial activity of the bio-capped CuO nanoparticles.","PeriodicalId":12768,"journal":{"name":"Green Chemistry Letters and Reviews","volume":"395 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135798727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prepared L–AgNPs were spherical with a size of approximately 16–22 nm, whereas the structure of lignosulfonate did not change during the synthesis. The synthetic method is green, simple and fast. As a heavy metal, establishing a green and rapid detection method for mercury ion is very important. L–AgNPs exhibited high selectivity for mercury (II), a detection range of 0–68 µM, and a minimum detection limit of 7 nM. The detection method developed in this work was used for the determination of mercury (II) in actual water samples, and the results agreed well with those obtained by a colorimetric method. This study provides a new idea for the practice of green chemistry and a novel method for the detection of mercury (II).

The principles of green chemistry and United Nations Sustainable Development Goals (SDGs) are guides to help us reach a sustainable future. Educators use these to create resources to connect green principles and sustainability goals. Systems thinking provides the method for creating relevant lectures, meaningful activities, and cohesive assessments in an educational module. A week-long stoichiometry module for introductory chemistry is described. Students tackle multiple learning outcomes to answer complex questions such as ‘what makes an reaction efficient?’. This module relates SDGs #7 and #13, clean energy and climate action, to the green principle of atom economy, which evaluates the efficiency of chemical transformations. The process of backward design is used with systems thinking to map learning outcomes across the module. Students demonstrate skills related to individual outcomes and use their knowledge to evaluate chemical systems from multiple perspectives across outcomes. Incorporating real-world examples the module explores how incomplete combustion impacts human health and the environment while exploring the material efficiency of making different fuels. The context and practice of sustainable science can be used to teach chemistry in a systematic way.

Transition state theory (TST) was utilized to estimate the bimolecular rate constants. Ten oxidation pathways have been investigated, and all of them are exothermic. The potential energy diagram has been sketched using different pre- and post-reactive complexes for all reaction pathways. Rate coefficient calculations were obtained directly by connecting the separated reactants with different transition states. The results indicate that the reaction of IPA with OH radicals occurs in the ground state rather than the excited state, and the rate constants obtained directly and from the effective approach are the same, which confirmed the accuracy of the estimated pre-reactive complexes and the reaction mechanism. Rate constants and branching ratios show that hydrogen atom abstraction from the iso C − H (C2 atom) bond is the most kinetically preferable route up to 1000 K, while at higher temperatures, H-atom abstraction from the out-of-plane CH3 group (C3 atom) became the most dominant route with high competition with that of the in-plane CH3 group (C4 atom).

Due to the special position of its amino group, 3-aminopyrazole is easy to form a hydrogen bond donor–acceptor-donor, and the hydrogen bond ‘zipper’ structure enhances the binding ability of such compounds to receptors. This work provides a new one-pot three-components reaction for the efficient construction of multi-substituted aminopyrazoles derivatives via iodine-mediated cyclization in the presence of ethanol. After that, the potential mechanism of the reaction was explored based on the control transformation experimental and density functional theory (DFT) calculations. In addition, all obtained multi-substituted aminopyrazole derivatives were fully investigated for their application as potential anti-cancer agents, and some of which have been proved to exhibit excellent anti-cancer activity against A875 and HepG2 cell lines, and the possible structure–activity relationships also has been discussed based on the screening results.
