As non-renewable resources continue to dwindle, the importance of green energy generation and storage is growing. In order to store energy effectively, especially for renewable sources, a reliable energy storage system needs to be developed. In this study, CoCr₂O₄ (CCO) and N-rGO/CCO were fabricated employing a hydrothermal approach. The electrochemical performance of CCO and N-rGO/CCO was assessed by GCD at 1 A g^-1, CCO and N-rGO/CCO nanohybrid displayed specific capacitances (C_s) of 497.6 and 1062.25 F g^-1, respectively. The structural defects and uniform anchoring of CCO nanoparticle on N-rGO nanosheets result in the improved electrochemical perfomance and C_s of the N-rGO/CCO nanohybrid being consistently superior than CCO across all current densities. Furthermore, in two-electrode systems exhibit C_s of 225.72 F g^-1 with P_d (880 W kg^-1), confirming the symmetric behaviour of N-rGO/CCO. In a 2-electrode setup, N-rGO/CCO demonstrate outstanding supercapacitive performance. This is due to the unique characteristics of N-rGO, which provide a flexible and scalable framework for the growth of CCO nanoparticles. Moreover, N-rGO/CCO nanohybrid has substantial potential to be used for supercapacitor electrode material, offering greater E_d (6.06 Wh kg^-1). Electrochemical investigations indicates that N-rGO improves CCO stability by enhancing C_s through an extended discharge lifespan. N-rGO nanosheets within the nanohybrid enhance electron flow by acting as a conductive substrate. As a result, the N-rGO/CCO is an outstanding material for electrodes in supercapacitors and various energy storing devices.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1040 ","pages":"Article 123824"},"PeriodicalIF":2.1,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144886862","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 current research described a cost-efficient and eco-friendly approach for the Ag NPs green synthesis from AgNO₃ using an aqueous extract of <em>Phellodendron amurense</em> leaves as a reducing agent. The phenolics hydroxyl functional groups in <em>P. amurense</em> leaf extract act as capping/stabilizing and reducing agents. The Ag NPs/<em>P. amurense</em> nanocomposite was characterized using techniques such as UV-Vis, TEM, SEM, EDX, ICP-OES, and XRD. Results from SEM and TEM revealed that the generated silver nanoparticles had a spherical shape structure and their size was around 20 to 30 nm. NCI-H661 human lung adenocarcinoma cell line was used to evaluate the biogenic Ag NPs/<em>P. amurense</em> nanocomposite anti-lung cancer capabilities. The MTT experiment showed that the Ag NPs/<em>P. amurense</em> nanocomposite could strongly inhibit the proliferation of NCI-H661 human lung adenocarcinoma cells. Without causing any damage to the normal cell line, Ag NPs/<em>P. amurense</em> nanocomposite demonstrated extremely poor cell survival and dose-dependent anti-human lung cancer effects. The Ag NPs/<em>P. amurense</em> nanocomposite' IC₅₀ value against the NCI-H661 cell line was 147 µg/ml. Through a detailed examination of the Phosphatidylinositol 3-Kinase (PI3K)/Protein Kinase B (Akt)/Mammalian Target of Rapamycin (mTOR) pathway, it was observed that Ag NPs/<em>P. amurense</em> nanocomposite can alter the PI3K/AKT/mTOR pathway, affecting NCI-H661 human lung adenocarcinoma cells cell growth and death. This pathway may contribute to the cell cycle inhibition and apoptosis induction by Ag NPs/<em>P. amurense</em> nanocomposite. Our data suggest that Ag NPs/<em>P. amurense</em> nanocomposite might be a very promising anticancer drug against human lung adenocarcinoma cells. The catalytic performance of the Ag NPs/<em>P. amurense</em> was investigated for the generation of propargylamines derivatives through a three-component reaction involving amines, alkynes, and aldehydes (A³ coupling).

In this review, the main goal is to describe the anticancer properties studied on Iridium complexes so that Iridium analogues may be considered as alternatives to Cis-platin.
