However, the internal insulation defect existed in GIS would inevitably lead to Partial Discharge (PD), and cause the composition of SF({}_{6}) to HF, SF({}_{4}), SOF({}_{2}), SO({}_{2})F({}_{2}) and SO({}_{2}) and other characteristic component gases. The decomposition phenomenon would greatly reduce the insulation performance of SF({}_{6}) insulated equipment, and lead to insulation faults and power failure. Many sensing nonmaterial's such as carbon nanotube and graphene, metal oxides such as SnO({}_{2}) TiO({}_{2}), and ZnO were explored as chemical gas sensors to detect SF({}_{6}) decomposed species with rapid response, high sensitivity and selectivity, in order to guarantee the operation status of SF({}_{6}) insulation equipments. In this paper, we attempt to comprehensively understand the adsorption and sensing property of BNNT to SO({}_{2}), SOF({}_{2}) and SO({}_{2})F({}_{2}) were investigated based on the DFT method to explore its potential as a chemical gas sensor. Our theoretical simulation results show that BNNT could be a promising sensor for sensitive detection which would be beneficial for evaluating the running status of SF(_6) high voltage insulated equipments.","PeriodicalId":300387,"journal":{"name":"Journal of Atomic, Molecular, Condensed Matter and Nano Physics","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123729785","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 Morocco’s case, the economic cost of air quality degradation is about 1.62 percent of GDP. Also, several studies reported the significant influence of local meteorological factors on the PM10 daily concentration during the synoptic climate conditions and cyclonic circulation. In this sense, Agadir city is a coastal city, and its proximity to the desert makes it very exposed to particles. Accordingly, this study allows, on one hand, to evaluate the performance and to understand the limitations of the WRF-CHIMERE modeling system used to simulate the maximum concentrations of PM10 in the city of Agadir, based on observations made in spring and summer 2010. On another hand, in order to better understand the situation, the impact of meteorological variables and anthropogenic emissions on PM10 is being investigated. The preliminary results of air quality modeling pointed out some PM10 dispersion issues in the area of Agadir. In particular, the results highlighted the influence of temperature and wind speed, which were correlated with PM10 concentration. Besides, CHIMERE simulations suggested that anthropogenic emissions control is essential to reduce PM10 by up to 15%. The PM10 underestimation is attributed to the meteorological observation/model discrepancy and the effect of emissions. The results underline the importance of meteorology on PM10 dispersion and have significant policy considerations for Moroccan air quality strategy.","PeriodicalId":300387,"journal":{"name":"Journal of Atomic, Molecular, Condensed Matter and Nano Physics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115359956","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}
