In recent times, treatment of seeds with low magnetic fields has been shown to improve growth and yield of crop plants. Physical treatment of seeds with low magnetic field of 100 – 200 mT strength improves germination and early seedling growth of soybean and maize seeds. There have been several studies on the impact of plasma on the seeds since plasma treatment improves germination of seeds and subsequent growth of the seedlings. This has been observed in the seeds of wheat, soybean, clover, rye, barley, pea and lapin. After plasma treatment shoot weight increased by 30% in wheat under experimental conditions. The mechanism of plasma induced bio-stimulation of germination and growth of seeds is yet to be analyzed in detail. There are different methods to increase the germination and growth of seeds by plasma treatment like DC Glow discharge plasma, RF Glow discharge plasma, Dielectric Barrier Discharge plasma (DBD) and plasma activated water (PAW) .We at center of excellence for plasma research have developed a plasma glow discharge system for the Germination and Growth of seeds with glow discharge plasma treatment.","PeriodicalId":18837,"journal":{"name":"NATIONAL CONFERENCE ON PHYSICS AND CHEMISTRY OF MATERIALS: NCPCM2020","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82674693","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 development of highly efficient electrode materials for the electro-catalytic oxidation of phenol from waste-water is a primary goal of environmental protection. In the present work, we have studied different metal sulphides (CoS, FeS, NiS, CuS) for phenol degradation. Using the density functional theory (DFT) based approach, we have studied the performance of these metal-sulphides for the electro-Fenton like processes and argue that NiS to be the best candidate, as seen in the recent experiment. From the calculated adsorption energies and activation barriers for the desorption of various important intermediates such as H2O2, OH, 2OH etc., the Bader surface charges that can be directly related to Lewis acidic behaviour, we conclude that NiS shows the optimal catalytic behavior required for the degradation of phenols.","PeriodicalId":18837,"journal":{"name":"NATIONAL CONFERENCE ON PHYSICS AND CHEMISTRY OF MATERIALS: NCPCM2020","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75362044","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}
