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}

Current work aims to synthesize lignosulfonate grafted sodium acrylate hydrogel (LS-g-SAH) and investigate its application in urea release behaviour. The hydrogel has been characterized by different techniques. The release kinetics has been analyzed by using a UV-visible spectrophotometer. The optimized composition of lignosulfonate, KPS, and N,N’-MBA has shown the highest water absorbency of 560 g g-1 in distilled water. The equilibrium swollen LS-g-SAH 12 hydrogel has slowly released 60% of loaded urea in 24 h and followed first-order release kinetics. Soil treatment with hydrogel has shown a significant effect in reducing the water evaporation rate. It also improved the seed germination and average height of wheatgrass. The synthesized LS-g-SAH is, thus, expected to have potential application in modern sustainable agriculture.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"10 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":"135659490","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}

The influences of various experimental factors such as contact time, adsorbent dosage, pH of solution, initial dye concentration and temperature have been investigated. Batch adsorption studies has manifested that the maximum adsorption capacity of MB is around 99.9 mg/g in 10 min with 25 mg adsorbent mass at an initial concentration of 100 mg/L at ambient temperature of 25°C and natural pH of solution (pH = 5.8 for NiO-Mt and pH = 6.3 for commercial bentonite). The adsorption kinetics and isotherms are well fitted by pseudo-second order and Langmuir models, respectively. The thermodynamic parameters such as the changes in Gibbs free energy, enthalpy, and entropy are determined. The MB adsorption is physical, spontaneous and exothermic for both adsorbents.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"105 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":"135660076","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}

With consideration of the appropriate similarity framework, the fundamental governing flow equations are converted into a system of non-dimensional equations. The bvp4c, a built-in solver of MATLAB software, is utilized to compute the numerical results of the flow problem. The present model is validated with previously published literature. The impacts of several related flow parameters on velocity, temperature, and concentration profiles have been displayed graphically. Also, the mass and heat transfer rates along with the coefficients of skin friction are calculated and discussed numerically. It is found that an increment in the thermal radiation parameter increases the fluid temperature, and the concentration gradient boosts up for the enhancement of the Soret number.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"154 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":"135660828","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}

Raj","doi":"10.56042/ijct.v30i3.69307","DOIUrl":"https://doi.org/10.56042/ijct.v30i3.69307","url":null,"abstract":"There are several potential uses for green nanoparticle amalgamated in the medicinal and environmental sciences. Green synthesis specifically tries to reduce the use of harmful chemicals. For instance, it is often acceptable to employ organic resources like plants. In a single green synthesis step, biomolecules found in plant extract may transform metal ions into nanoparticles. This naturally occurring conversion of a metal ion to a base metal may be carried out quickly, conveniently, and at ambient temperature and pressure. In the current study, the production of CuNPs utilizing different-sized Nelumbo nucifera leaf extract has been reported. In order to determine how CuNPs generated, several techniques including UV-Visible, XRD, SEM, EDAX, FTIR, and cyclic voltammetry studies were used. The UV-Visible spectra of the amalgamated CuNPs show a peak between 250 and 450 nm. The morphology of CuNPs are spike in shapes with sizes of 33nm for 10mM and 25nm for 50mM, and the nanoparticles are crystalline in nature, according to the XRD and SEM examinations. The amalgamated CuNPs contain 37.55% copper, according to EDAX, and FTIR shows the absorption peak of copper at 1640 and 576 cm -1 .The oxidation and reduction of amalgamated CuNPs are visible by cyclic voltammetry. CuNPs have been put to the test against Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa for their antibacterial properties. CuNPs show the greatest zone of inhibition when used against Pseudomonas aeruginosa . Aspergillus flavus and Candida albicans have been used as test subjects for the antifungal testing of CuNPs. The CuNPs against Candida albicans show the largest zone of inhibition. CuNPs demonstrate strong antibacterial and antifungal efficacy, which means they have a considerable potential for application in the development of medications used to treat bacterial and fungal infections. The electrical potential difference of amalgamated CuNPs has been measured using a voltmeter and it is found that as concentration rises, so does the electrical potential difference.","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":"70701692","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}
