FTIR analysis confirmed the successful incorporation of metal oxides into the DES matrix, evidenced by characteristic metal-oxygen (W-O and Mo-O) stretching vibrations observed within the 947-767 cm-1 and functional group interactions. Scanning electron microscopy imaging revealed agglomerated, irregularly shaped particles with porous morphologies, while energy dispersive X-ray spectroscopy confirmed the homogeneous distribution of W and Mo within the composite. X-Ray diffraction patterns indicated a predominantly amorphous structure with broad peaks corresponding to semicrystalline tungsten and molybdenum oxide phases. Ultraviolet-visible spectroscopy showed strong absorption in the 259-476 nm range, confirming efficient light-induced activation. The nanocomposites exhibited excellent photochromic performance, transitioning rapidly from cream-yellow to blue within three seconds under UV exposure, and reversibly fading in an oxygen-rich environment within 50 min. Electrochemical impedance spectroscopy (EIS) further revealed that the W-Mo (0.8:0.2) composite had the lowest charge transfer resistance, enhancing electron transport and accelerating photo-switching behaviour. The combined structural, optical, and electrochemical properties of these materials underscore their promise for use in smart windows, UV sensors, and dynamic display technologies.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://or.niscpr.res.in/index.php/IJCT/article/download/22701/5354","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The source of the green inhibitor is the Salsola oppositifolia plant, from which the method of obtaining the green inhibitor extract is studied. The obtained extract is studied as a green inhibitor in 0.5 M HCl solution for corrosion protection of carbon steel structures. In determining the efficacy of a green inhibitor derived from the Salsola oppositifolia plant, practical experiments have been performed at two different temperatures (298 K and 313 K) and at different concentrations (200 mg/L , 400 mg/L, 600 mg/L, and 1000 mg/L). Adsorption of green inhibitor on steel surface has been studied using Langmuir and Temkin isotherms. The effect of temperature and concentration on the corrosion rate is also studied. The gravimetric method is used to determine the effectiveness of the green inhibitor and it is found that its maximum concentration is 91.86%. The mechanism of action of the steel surface and a post-experimental steel sample are studied by scanning electron microscope analysis. Salsola oppositifolia extract is a good green inhibitor due to the presence of hetero atomic organic compounds in the main component.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"4 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":"135611975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To meet fossil fuel demand in the future, alternative fuel for diesel fuel is necessary. The technique for engine modification is also considered as the latest advance in engine research aimed to complete combustion. The engine has been coated with a mixture of a ceramic thermal barrier material of 88% Yttria Stabilized Zirconia (YSZ), 4% Magnesium oxide (MgO), and 8% Titanium oxide (TiO 2 ) of 150 μ m thickness by the plasma spray process. After engine modification, the coated engine has been analyzed with the mixing of Copper oxide (CuO) nanoadditive to the B20 Punnai Methyl Ester. The structural and chemical constituents of the biofuel are determined using Fourier transform infrared spectroscopy and gas chromatography. The test result noted that brake thermal efficiency is increased by 17.14% for the coated engine as compared to the uncoated engine. The brake specific fuel consumption for the tested fuel used in the coated engine is decreased by 11.16%. Engine emission parameters are reduced especially oxides of nitrogen (NO x ) emission of 10.84% for the tested fuel in the coated engine.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"35 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":"135660850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals' recalcitrance in wastewater has been shown to be a difficult issue. Further, drinking water quality must be at its highest for human health to be at its best; nevertheless, a number of human activities are continuously degrading it, which has an effect on human health either directly or indirectly. Because heavy metals are the primary causes of many chronic illnesses and have a tendency to bio accumulate, they are giving rise to a lot of worries. Technologies from all over the world are being developed to address the demand for clean drinking water. The objective of the current study is to raise awareness of the need to remove dangerous dense metals from various types of wastewater and the application of modified graphene nanocomposite for their adsorption-based removal. Graphene-based nanocomposite materials have been picked for this application due to their large surface area, superior mechanical strength, and reactivity towards polar and nonpolar contaminants for the electrostatic emission of the heavy metal ions arsenic (As)","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70702015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
