An application of essential oils comprising antimicrobial activities was recently described in the SWASTIIK technology (Safe Water and Sustainable Technology Initiative from Indian Knowledgebase) in conjunction with cavitation/ intense mixing for drinking water treatment. Further, it is intended to demonstrate the efficacy of SWASTIIK technology to combat multi virulent bacteria and emerging viruses such as Escherichia coli and SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-2) respectively with the help of in silico computational tools. Docking study indicated eugenol and thymol were the most effective ligands against the microorganisms, although SARS-CoV-2 performed better with a low binding affinity (-7.2 kcal/mol) than multi-virulent E. coli (-4.5 kcal/mol). SWASTIIK technology for eliminating harmful microorganisms is, therefore, expected to be more effective in combating viruses, including SARS-CoV-2. Further, favorable ADMET results suggest suitability of the active components for further clinical trials study or for possible health benefits of water treated using SWASTIIK technology. In view of lack of human studies, to evaluate the effectiveness and safety of essential oils for direct intake, clinical trials with more well-designed protocols are needed.","PeriodicalId":136251,"journal":{"name":"Journal of ISAS","volume":"339 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140473267","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}

Here in this work, the role of polyethylene glycol as surfactant in the formation of 3R-MoS2 is recognized. XRD and FTIR results provide structural elucidation and bonding information in the compound. More detailed crystal structure investigations and polyhedral visualizations were obtained in the Rietveld refinement procedure. The trigonal prismatic metal coordination in the 3R phase is portrayed with the ABC-ABC type layer stacking sequence. The morphology of layered 3R-MoS2 nanostructure was identified from HRTEM images and the percentage composition from FESEM mapping and EDAX analyses. Temperature dependent mass loss in the compound is monitored and the quantitative analysis confirms the complete transformation of 3R-MoS2 -MoO3 at a temperature of 398 °C. Endo and exothermic peaks in the DSC and DTA measurements help to substantiate the results. Thus the work highlights the temperature assisted conversion of sulphide (3R-MoS2 -MoO3) of molybdenum at 398°C by cleavage of S-S bonds and preserving the layered nature.","PeriodicalId":136251,"journal":{"name":"Journal of ISAS","volume":"460 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478031","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}

Zinc oxide (ZnO) nanoparticles show varied morphologies and significant activities especially after doped with different metals. In this work, ZnO nanoparticles, Selenium dioxide (SeO2) doped Zinc oxide nanoparticles and Silicon dioxide (SiO2) doped Zinc oxide nanoparticles are synthesised by sol-gel method. The dopant effect on ZnO for band gap energy, crystal size and morphology are investigated by analysing the UV-DRS, powder X-ray diffraction and FESEM measurements respectively. The photocatalytic activities of these synthesised nanoparticles are compared by subjecting them into degradation of drug Lasix (furosemide) under UV and Solar irradiation sources. The progress of drug degradation is studied by measuring absorbance versus time interval at constant wavelength (325 nm) of the drug. The rate coefficient values found in this oxidative (H2O2) and reductive (NaBH4) catalytic degradation process of the drug is found efficient in solar irradiations.

Biogenic nanoparticles have emerged as a potential solution owing to their low cost, eco-friendliness, and high remediation efficiency. Among these nanoparticles, chitosan-based nanoparticles have gained significant attention for the treatment of wastewater. Chitosan, a biodegradable polysaccharide derived from chitin, possesses unique physicochemical properties that make it a suitable candidate for nanoparticle synthesis. The present review focuses on the synthesis, characterization, and applications of chitosan-based biogenic nanoparticles for wastewater remediation. Various synthesis methods, such as chemical cross-linking, precipitation, biosynthesis, solvent evaporation, and emulsion techniques are discussed. The characterization of chitosan nanoparticles using techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), and, Fourier-transform infrared spectroscopy (FTIR) among others were also highlighted to provide insights into their structural and chemical properties. Additionally, the applications of chitosan-based nanoparticles in wastewater remediation, including the adsorption of heavy metals, organic dyes, and pharmaceuticals, are discussed.

After the death of an individual, a post-mortem examination was conducted. As part of the investigation, the viscera (I) and (II) were sent to the Mini Forensic Science Laboratory in Solapur. The Medical Officer, in their report, mentioned that no injuries or defensive marks were found on the body, except for a small prick mark or bite mark with clotted blood observed on the right foot, between the small toe and adjacent fingers. Upon cleaning the area, it was noticed that one spot was more prominent, while the other spot was faint. Since there were no eyewitnesses present at the crime scene, the police recorded in their inquest that the death might be a result of a snake bite. No formal complaint was registered at that time. However, the viscera samples were preserved for further examination and a final opinion. In the analysis of the viscera, techniques such as Thin-Layer Chromatography (TLC) and Gas Chromatography-Mass Spectrometry (GC-MS) were employed.

It reduces friction by the formation of thin film between two surfaces in contact and by improving efficiency and reducing wear. For any system to work efficiently and effectively appropriate lubricant is needed. Fresh lubricating oil needs to meet specifications of Original Equipment Manufacturers (OEMs). Applying lubricant regularly on tool increases life on usage and durability but a situation comes when the oil starts degrading may be due to depletion of additives or tool break down. Degraded oil is tested by using different physicochemical properties and also by employing different sophisticated analytical techniques like infrared spectroscopy (FTIR), Gas chromatography (GC), Inductively coupled plasma atomic emission spectroscopy (ICPAES), etc. In this article, we shall discuss some basics of lubrication, different lubrication regimes and various kinds of lubricants used for various industrial and automotive applications. Some case studies of oil and also their representative formulations, testing and interpretation of results is being presented for understanding of various lubricants.","PeriodicalId":136251,"journal":{"name":"Journal of ISAS","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122427314","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}
