The nanoparticles are synthesized with the modified citrate rout at different temperatures. X-ray diffraction measurements revealed three dominant peaks 23.040, 40.5170 .47.170, 58.660 which confirms the perovskite-like structure. The average crystallite size the nanoparticles are found to be 20 to 32nm. All the synthesized nanoparticles exhibit ferromagnetic ordering close to the phase transition temperatures. The size dependent magnetic and electrical transport properties are explored at different fields and temperature. Saturation magnetization is found to decrease with decreasing particle diameter. It is found that the particle size can tune the trend of coercive field. Coercive field first increases from 78 to 210 Oe and then decreases to 174 Oe. The electrical transition temperature is found to be 158 K for 20nm particle. Oxygen deficiency in such system generally reduces Mn4+ to Mn3+ to keep the charge neutrality of the structure and hence it destroys the conduction path ways to mobile electrons, at least in long range, and thus insulating behavior becomes more prominent in the larger temperature range. The trend at lower temperature attribute to the coulomb blockade.","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"151 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86172591","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}

It is the cry of the masses which stimulates investigation of the local ambient environment for Particulate Matter (PM) and its sources. The purpose has been achieved by using versatile techniques such as Micro-Orifice Uniform Deposit Impactor (MOUDI™) for collection, Fourier Transform Infrared (FTIR) Spectrometry for characterization by Size Mass Concentration, and Atomic Absorption Spectroscopy techniques were utilized to identify and quantify different PM in the study area. The urban territories (different locations of Okara) were found contaminated with coarse, fine, and ultra-fine Particulate matter because of local industries and vehicular emissions. Coarse particles (PM10) of size 3.2 µm and 10 µm, fine particles (PM2.5) and Ultra-fine particles (0.056 µm) were quantified around 8 ?g/m3, 10 ?g/m3 and 25 ?g/m3 respectively. The obtained results could be linked with the widespread use of low-quality fossil fuels and the increased number of vehicles. The ultimate solution to the prevailing scenario can be in hand by switching over to renewable energies such as solar, hydrogen, and wind.","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82773994","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}

No one of us can deny its contributions in the medical field. Disease detection is one of the greatest achievements of Machine Learning. During the pandemic of COVID-19, medical emergency and less of experts has affected the health sector a lot. Detection of Covid-19 has become much more important than its cure to protect others from the virus. Detection of Covid-19 with our model is much easier through the x-ray images. The model using Convolutional Neural Network has trained on our self-made algorithm which was named to be Lungs X Ray Neural Networks (LxN) providing much more accurate than any other model available. It can process multiple datasets in a batch and our model is generalized very well with an accuracy of 98.8 % on validation and 98.0% on test set. The dataset for solving this problem was obtained from the open-source ieee8023 GitHub Repository, constantly updating with the images around the globe, containing a combo of both corona and non-corona cases. The result obtained from the model is y ? {1, 0} indicating Corona presence or absence respectively. Lungs X Ray Neural Networks (LxN) model is not only specialized on corona data but can be fine-tuned on any other lung images like pneumonia. Thus LxN has significant role in the research area of AI in case of medicine.","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80590625","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}
