Gd-substituted BFO were produced in this work utilizing Pechini’s modified Sol-Gel auto combustion technique. The development of a pure perovskite structure was confirmed by X-ray diffraction (XRD), with no secondary phases identified. The lattice parameters were observed to decrease as Gd concentration increased, showing that Gd ions were successfully incorporated into the BFO lattice. The microstructural characteristics of the produced NPs were investigated using the HRTEM to evaluate particle size and shape. UV-Vis spectroscopy was used to analyze the optical characteristics of the NPs, which revealed a reduction in optical bandgap with Gd substitution. The improved optical characteristics can be attributed to a change in the electronic band structure caused by Gd substitution. Overall, Gd-substituted BFO perovskites displays remarkable optical properties, indicating their potential use in optoelectronic devices and as a catalyst for the degradation of synthetic and organic dyes.","PeriodicalId":13509,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135496255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanocomposites were fabricated with different weights per cent (0.25 wt. %, 0.5wt. %, and 0.75wt. %, 1wt. %, and 2wt. %, respectively) of Fe3O4-OA into the PVA matrix. The synthesized nanocomposites were characterized using FTIR, UV–Vis, XRD, Contact angle, Impedance spectroscopy, SEM and EDS. UV-Vis spectra initially confirmed the interaction of Fe-OA NPs into the PVA matrix by observing peaks at 223nm, 325nm and 410nm. The FTIR investigation uncovered evidence of an interaction between the NPs and the PVA polymer matrix. The incorporation of NPs into a polymer matrix shows an enhancement in various properties due to its nature. The surface properties of the composites were studied using the contact angle technique. The electric properties of Fe3O4-oleate/PVA nanocomposite films were estimated using impedance spectroscopy. Due to the dispersion of Fe3O4-oleate NPs into the PVA matrix, we obtained the polarization in dipoles, resulting in good AC-Conductivity properties. These synthesized nanocomposites may potentially use for electronic applications.","PeriodicalId":13509,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136217596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of bio-marker prediction approach makes prompt identification and therapeutic diagnosis of these individuals difficult. With the advent of targeted medicines, it has become increasingly crucial to diagnose RA early in order to provide safe and timely disease management that can minimize long-term consequences that include joint tissue damage. Raman spectroscopy is currently gaining clinical acceptability as a label-free, non-invasive tool for obtaining a thorough biochemical signature of biological sample composition. The purpose of this research was to look at using confocal Raman spectroscopy in conjunction with statistical data analysis as an auxiliary or supplementary tool for completing the diagnostic process of RA using peripheral blood serum. Raman intensities and Functional group frequencies are assigned to amide chains in proteins and other intermediate structural components such as lipids of a normal individual and a RA patient were distinguished, and biochemical alterations were found. Experimental results shows that spectral shift in region I and region II in Figure 1 identifies the concentration of nucleic acids and TNF-α increases respectively, which causes inflammation in our body that initiates RA disease.","PeriodicalId":13509,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135496243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The studies of the electrical properties of semiconducting thin films have been primarily provoked by attractive micro-electronic device applications. Bismuth Telluride (Bi2Te3) is the most widely used material among the various V- VI compounds. In this study, thin films of Bi2Te3 were fabricated onto different substrates (i.e., glass and silica) by using thermal evaporation technique. Their structural, morphological, optical, and electrical properties were investigated using X-ray diffraction (XRD), Field Emission-Scanning Electron Microscopy (FE-SEM), Photoluminescence (PL) spectroscopy, and Source meter instrument, respectively. XRD analysis showed that the films were crystalline in nature. FE-SEM images showed that the films have a homogenous and compact grain surface. The optical band gap was about 2 eV for both types of film. The I-V characteristics of thin films were analysed at temperatures ranging from 30 °C to 100 °C. It was found that the film fabricated onto silica substrates showed large electrical conductivity as compared to the others. Also, the increment in electrical conductivity was observed with the temperature indicating that the prepared films have a negative temperature coefficient of resistance.","PeriodicalId":13509,"journal":{"name":"Indian Journal of Pure & Applied Physics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135496249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
