The advantages of this material are its low cost, chemical stability, and remarkable electrochemical performance. The applications are found particularly in the fields of photovoltaic and energy storage. Growing energy supercapacitors have gotten a lot of interest because of their promising capacitance, availability, obvious electrochemical response, and ease of manufacture of copper oxides to address the high need for efficient electrochemical energy storage systems. This research describes a hydrothermal technique to produce GO/CuO nanocomposite for supercapacitor applications. XRD, FTIR, SEM, UV, and TGA, were used to evaluate the crystal nature, morphology, and chemical states of the produced GO/CuO nanocomposite, and electrochemical performance was tested using CV the manufactured nanocomposite materials as supercapacitor electrodes.

Chemical compounds such as flavonoids and their diverse bioactivity have triggered research that prioritizes quality and efficiency. This study was designed to optimize the extraction solvent in producing flavonoids from the rhizome of C. xanthorrhiza based on a simplex centroid design using Design Expert 13.0. Extractor solvents (water, acetone, ethanol, and methanol), as well as their combinations, were studied to test the total flavonoid content using the calorimetric aluminum chloride method by spectrophotometer. The experimental results with the special cubic model are a good and reliable fit for recovering flavonoids. The optimal conditions obtained were highly accurate at the desirability value of 1.00 with a mixed solvent of methanol (0.445) and ethanol (0.555), which resulted in total flavonoid content of 144.665 mg quercetin equivalent per gram dry weight. Methanol and ethanol combined can be an effective solvent option for extracting high amounts of active compounds (especially flavonoids) in C. xanthorrhiza rhizome.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69411313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
