This volcanic complex is situated in northern Sumatra, Aceh Province, Indonesia. Geothermal potential in this area is manifested by several hot springs discharged in the Pinto Rime Gayo (PRG), Simpang Balek (SB), Uning Bertih (UB), and Silih Nara (SN) springs. All springs have a neutral pH and a surface temperature ranges from 34.10 to 67.11ºC. A geochemical investigation was conducted on the hot springs to understand the hydrochemistry of the geothermal fluid and estimate the reservoir temperature of the geothermal area. This investigation was an exploration study of geothermal resources in the area. Hot waters in the PRG, SB, UB, and SN springs were collected and analyzed in May 2018 to identify the cations and anions contained. Piper and Cl-SO 4 -HCO 3 diagrams have been plotted to characterize the geothermal fluid. Na/K geothermometer has been applied to calculate the temperature of the geothermal reservoir. Isotope analysis has also been conducted to estimate the origin of the fluid. This research discovered that the major element of the water demonstrates the various geothermal water types. The PRG spring contains Na-K-Cl water, whereas the SN spring contains diluted Cl-HCO 3 water with mixed cation concentrations of Ca, Mg, Na, and K. The waters in SB and UB are a mixed form of Cl-HCO 3 -SO 4 waters. According to the δD and δ 18 O relationship , t he genesis of geothermal fluids is hydrothermal fluids of meteoric water. Based on the Na/K geothermometer, the reservoir temperature of the Bur Ni Geureudong geothermal system is a range of 171-289ºC which is indicated as a high enthalpy system (>225ºC). It can be concluded the Bur Ni Geureudong geothermal region is recognized by this study as a promising source of renewable energy. Future work on geothermal exploration and utilization is expected to expand on the framework established by this present study.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135594894","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}

Furthermore, the resistance of bacteria to the existing antibiotics is a significant and vexing problem of the day. The hybrid pharmacophore structural modification concept is now widely used to develop new medications with synergistic activity or increased medication efficacy. This review looks at the benzimidazole hybrids that have evolved in the last two decades and have probable antibacterial action. Structure-activity relationship and study of molecular interaction are also examined to locate the course for the intent and expansion of benzimidazole hybrids by means of good pharmacokinetic and pharmacodynamic profiles. Based on the findings, it can be inferred that such hybrids that have substitution on both ring benzimidazole, as well as other heterocyclic rings, have better antibacterial potential rather than the hybrids that have substitution only on a single ring. Findings also indicate the crucial positions for substitution to have maximum antibacterial potential. The antibacterial activity not only depends on the substitution of rings but also depends on the attachment of the linker group between two rings. Resulting, it is thought worthwhile to synthesize novel benzimidazole hybrids having appropriate linkers and substituents with the goal of having potent bactericidal activity.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136257356","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}

Graphene acts as an electron transfer agent and performs well as an electrode material in supercapacitors. However, mass production of graphene remains a major challenge. According to this research paper, naturally occurring graphite from the earth is refined and re-extracted. Hummer's method was used to prepare graphene oxide from well-purified flake graphite with the addition of both H 2 SO 4 as a guest and KMnO 4 as an oxidizing agent. Recently, ZIF-67@rGO nanocomposites have been widely used due to their high surface area, uniform porosity, and relatively high thermal and chemical stability.When comparing graphite and graphene oxide, graphene oxide spacing distance is much more than graphite. It is well known that graphene oxide contains a large number of oxygen-containing functional groups due to graphite oxidation. Another common feature of rGO is that fold-like structures are observed on both the surface and edges of rGO. Also,ZIF-67@rGO nanocomposite was prepared by mixing equal amounts of crystalline ZIF-67 and very fine rGO powder using a simple hydrothermal and stirring method. Such instruments FT-IR, XRD, UV, and SEM have been used to characterize the consequences of these factors on the structure and attribute of GO, rGO, and ZIF-67@rGO. In general, looking at the results and properties of rGO/ZIF-67 air gel, it is confirmed that this nanocomposite material is an alternative composition for use as an electrode material for electrodes in symmetric supercapacitor storage devices.","PeriodicalId":21063,"journal":{"name":"Rasayan Journal of Chemistry","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136303323","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}
