High-energy spectroscopic are well suited to provide information on these points. Among them, X-ray absorption spectroscopy (XAS) has been revealed to be a potential tool for determining the electronic and geometrical structure of complex compounds. In particular, K edge and XANES spectra of transition metal complexes have been the topic of several studies. The position and shape of X-ray absorption discontinuities have been used to deduce structural and chemical bonding information on transition metal complexes. The K-absorption spectra were recorded on the synchrotron radiation, i.e., on beamline BL-8 at RRCAT, Indore . XANES reveal to identify the allowed transitions and also the mixing or splitting of the final state orbital. [1, 2] Using known structural data, informative deductions on structure-bonding relations have been made. copper K-edge XANES spectra have been used since they probe 1s→3d, 1s→4p transitions respectively. Since the spectra can be influenced by the state of the d orbital, which is primarily responsible for the bonding with ligands. For Cu-containing complexes, Cu K-edge XANES has been widely used to derive information on the electronic and geometrical structure.","PeriodicalId":18837,"journal":{"name":"NATIONAL CONFERENCE ON PHYSICS AND CHEMISTRY OF MATERIALS: NCPCM2020","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81632246","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}

In this paper, the main discussion is on the thermal kinetics of Ber-PF composites. Ber with the botanical name ‘ZiziphusNummularia’ is the plant that is found in the arid region of western Rajasthan and other desert areas of the world. Fibers were extracted from this plant and these were used as reinforcement in phenol-formaldehyde resin. The sample of weight ratio of fibers-0.1 was prepared for thermal analysis. DSC experiments were performed on the sample with different heating rates – 10°C/min.15°C/min & 20°C/min. The values of the glass transition temperature, crystallization temperature, and heat of crystallization were calculated by analyzing DSC curves. The glass transition temperature varies between 61°C to 68°C, crystallization temperature varies between 160 ° C-170 ° C. The heats of crystallization vary from 515 mJ to 711mJ. Then the activation energy of the glass transition and crystallization process is calculated using Kissinger Model. The activation energy for glass transition is obtained roughly between 72kJ/mol - 185kJ/mol. The crystallization activation energy varies from 56kJ/mol-90kJ/mol. This study shows that reinforcing fiber with Phenol Formaldehyde enhances the thermal stability of the composite. Composites withBer’sfibers can be used in the manufacturing of automobile parts, toys, and sports instruments.","PeriodicalId":18837,"journal":{"name":"NATIONAL CONFERENCE ON PHYSICS AND CHEMISTRY OF MATERIALS: NCPCM2020","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82054096","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}

The current study aims at the synthesis of CuO nanoparticles with the use of Saraca Indica (Ashoka) leaf extract, which acts as a reducing agent. The experimental conditions were optimized for nano-range synthesis of CuO particles. The obtained CuO nanoparticles have been characterized using various analytical techniques such as SEM, FTIR, XRD. Scanning Electron Microscope images revealed that the nanoparticles are in petal like shaped structures, having an average crystallite size of~ 14 nm. The XRD graph confirmed that the obtained CuO nanoparticles have monoclinic structure and has a preferred Morphology Index. The FTIR plot further confirmed the presence of Cu-O bonding with a slight modifications with functional groups. CuO nanoparticles of different properties and dimensions can be prepared with the help of different leaf concentrations and Copper salts. This work provides a simple, environmental friendly, tailor made and a cost effective way of synthesizing CuO nanoparticles using Green method.","PeriodicalId":18837,"journal":{"name":"NATIONAL CONFERENCE ON PHYSICS AND CHEMISTRY OF MATERIALS: NCPCM2020","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80600167","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}
