Among the suggested solutions, heterogenous photocatalysis was progressively applied to degrade organic pollutants. Herein, a simple ethylene glycol refluxing (EGR) method was optimized to fabricate bismuth oxyiodide (BiOI) nanoparticles with a percentage yield of 94.2%. The EGR method's success in preparing BiOI nanomaterial was confirmed by the results of X-ray diffraction, energy dispersive spectroscopy, and Fourier-transform-infrared spectroscopy. The scanning-electron-microscopy and the transmission electron microscopy analysis revealed that the sunshine-like nanosheets are composed of tiny nanoparticles. The BiOI was employed for photocatalytic degradation of organic pollutants under visible light. The adsorption capability of BiOI was investigated prior to its photocatalytic activity, and both investigations showed appealing results. The outcomes of this study nominated both the EGR method for fast preparation of a nanoscale BiOI and the applicability of BiOI as a photocatalyst to swap the organic pollutants from contaminated water using the free-inexhaustible sunlight.","PeriodicalId":43605,"journal":{"name":"Journal of Optoelectronic and Biomedical Materials","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45898091","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}

Metamaterials can be used as environment or as part of the antenna. Based on the required parameters, metamaterials while designing antennas are used in various types. They are highly useful in enhancing the power gain, bandwidth, in creating dense and antennas of multiple frequencies. Usage of metamaterial in antenna require proper designing of unit cell. This require creation of cells with special properties at required frequency. Cloaking is a technique of making specific objects invisible. This was achieved by isolating electromagnetic waves in that region. This paper reviewed some of the cloaking devices that use the technique of coordinate transformation and scattering cancellation. Metamaterial sensors which are more efficient than sensors with traditional materials are reviewed. These sensors exhibit enhanced sensitivity. Sensors used in wave guides and liquid chemical detection were reviewed. Solar cells that use metamaterials were reviewed. Usage of these materials reduce the loss in solar radiation making the solar cell more efficient based on the design. Recent design in solar cells concentrate on obtaining maximum reflection through usage of back reflectors and increased absorption","PeriodicalId":43605,"journal":{"name":"Journal of Optoelectronic and Biomedical Materials","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42907571","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 present studyaimsto determine the effects of bone quality, implant length, and bone type on stress/strain distribution in bone and implant for a zirconia implant. The study was performed using the three dimensional finite element analysis and four different lengths, two types of implants, and four different bone qualities. The Elastic modulus of a cancellous bone was varied to represent the four different bone qualities. A load of 100 N was applied at the center of the abutment. The result of this current work shows that a bone is subjected to the maximum equivalent stress and strain when the cancellous bone density decreased. The screw type implant induced lesser strain than the cylinder type load. The study also confirms that longer implants produced lesser stain than shorter implants, and type I, and II bones induced lesser stresses than type III, and IV bones. The importance of bone quality has been confirmed from this study, and zirconia dental implants have induced lesser stresses.","PeriodicalId":43605,"journal":{"name":"Journal of Optoelectronic and Biomedical Materials","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46184692","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}
