Hollow/porous-walled SnO₂ nanoparticles were synthesized by simple oxidation of the prepared Sn chalcogenide precursors, for which the transformation mechanism was verified in detail. Nanoscale Kirkendall diffusion process was thoroughly investigated by morphological, crystallographic, and elemental analyses performed at various oxidation temperatures and times. To examine the morphological effect of hollow/porous-walled SnO₂ nanoparticles on the electrochemical performance, the synthesized nanoparticles were applied as anode material in a lithium-ion battery.

Therefore, methods to limit grain growth and simultaneously improve the radiation tolerance of nanocrystalline metals are needed. Amorphous intergranular films are unique grain boundary structures that are predicted to have improved sink efficiencies due to their increased thickness and amorphous structure, while also improving grain size stability. In this study, ball milled nanocrystalline Cu-Zr alloys are heat treated to either have only ordered grain boundaries or to contain amorphous intergranular films distributed within the grain boundary network, and are then subjected to in situ transmission electron microscopy irradiation and ex situ irradiation. Differences in defect density and grain growth due to grain boundary complexion type are then investigated. When amorphous intergranular films are incorporated within the material, fewer and smaller defect clusters are observed while grain growth is also limited, leading to nanocrystalline alloys with improved radiation tolerance.","PeriodicalId":119595,"journal":{"name":"Nanomaterials eJournal","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131890478","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}

Although a kinetic contribution has been recently proposed, namely, the formation of W-oxides at grain boundaries (GBs) by annealing, the formation mechanism is unclear. In this study, we annealed electrodeposited Ni-W alloys up to 600 °C; then, we examined the mechanical properties and microstructures to deeply understand the thermal stability of Ni-W alloys. Mechanical testing of annealed alloys demonstrated that the proof stress and hardness increased against the increase in annealing temperature in the range of 380-450 °C. At the mesoscale, microstructure observations revealed that the grain size was refined with increasing temperature from 390 to 450 °C. Finer-grained microstructures were maintained up to the annealing temperature of 520 °C. At the nanoscale, grain boundary structures were directly observed, and the chemistry was also demonstrated. These nanoscale analyses detected S segregation at GBs and triple junctions, whereas oxides and precipitates likely to affect grain growth were not identified. Our results and discussion indicate that grain refinements against an increase in the annealing temperature can be explained by the conventional relationship between the annealing temperature and nucleation number.","PeriodicalId":119595,"journal":{"name":"Nanomaterials eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114673179","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}

This research entitled “PREDICTING SAFETY INFORMATION OF DRUGS USING DATA MINING TECHNIQUE” incorporates information theory, which is the process of deriving the information from the unsupervised dataset through feature selection. Finding the best features that are similar to a test data is challenging task in current data era. This research presents a framework for discovering best feature selection from unsupervised datasets. The proposed research work presents a new approach to measure the features (attributes) in drug prediction dataset using the methodologies namely, data cleaning, Adaptive Relevance Feature Discovery and Random Forest Classification. There are number of pharmacy companies are available in the market with multiple medicines for same problem.This prediction of drugs is used to prescribe the medicines for the patient’s disease by analyzing the history of the patient’s health. Feature selection and dimensionality reduction is characterized by a regularity analysis where the feature values correspond to the number times that term appears in the dataset. The relevance feature discovery method gives a useful measure is used to find the similarity features between data points are likely to be in terms of their features property. Some of the challenges faced in finding the best feature selection include positive, negative and inconsistency. This Proposed work proposes an enhanced Drug prediction based on Random Forest classification method to estimate the feature searching that is measured using minimal redundancy optimization method corresponding to drug prediction dataset.","PeriodicalId":119595,"journal":{"name":"Nanomaterials eJournal","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127537674","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}
