The sample was calcined at various temperatures, including 750°C for the best results. Citric acid is a substance used to keep Nanoparticles from clumping together. The average particle size of nanoparticles was determined using powder x-ray diffraction, which revealed that as the sintered temperature is raised, the crystal size increases from 37 nm to 47 nm more. The sample was sintered at 750?C in furnace for 4 hours resulting in an increase in average grain size from 37nm to 47 nm measured using scanning Electron microscopy. The (124) phase of copper chromate having reference number 34-0424 JCPDS number obtained at 750°C with lattice parameter values 6.03?A and 7.8?A.

The cytotoxicity mostly depends on the reactive oxygen species (ROS) generation. For that purpose, TiO2 and ZnO nanoparticles have been synthesized by chemical route. Additionally, the ZnO was deposited on TiO2 to prepare nanocomposites ZnO@TiO2 .The Prepared nanoparticles (NPs) were characterized for their structural, morphological, optical and cytotoxicity behaviour by using techniques by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV–Visible spectroscopy and ROS generation .Their structural properties indicate the anatase phase of TiO2 while ZnO formed has shown hexagonal wurtzite structure. The SEM images showed that TiO2 NPs are formed in very small and uniform spherical morphology while ZnO formed in the form of small nanorods. Both types of morphology are visible in the ZnO@TiO2 nanocomposites as well. The optical energy band gap values show the reduction in the band gap of TiO2 when it’s composite has been made with ZnO nanorods. The anticancer activity was checked through ROS generation, MTT assay was used for this purpose. The results show almost uniform ROS generation in case of TiO2 and ZnO nanostructures but it shows a reduction in ROS generation in case of ZnO@TiO2 nanocomposites. This result may be related to the less available surface area for the individual particles of one type for ROS generation","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83116053","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}

Nowadays advancement in technology has made home automation as one of the emerging trends in modernization of controlling home devices. Conventionally all the home electrical devices are controlled via switches which utilizes the manual work and human effort. As the world is modernizing day by day so the cellular communication has given us a chance to control home appliances automatically from any place wirelessly. The proposed system will utilize the use of DTMF (Dual Tone Multiple Frequency) technique present in cellphones to produce MTMF (Multiple Tone Multiple Frequency) technique for our algorithm designed in MATLAB. This system provides controlling of home appliances through mobile phone by dialing a particular number and the digital output would be generated by DTMF and MTMF by receiving the command from cell phone. Hence the proposed system will meet the demand of people by providing them control of their home devices wirelessly from any place. Thus, the developed system reduces the human effort and the living environment will be more comfortable and satisfactory.","PeriodicalId":16381,"journal":{"name":"JOURNAL OF NANOSCOPE (JN)","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87824809","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}
