Ultrasonically cleaned and dried glass substrates were used for deposition of In2O3 thin films. Films were grown in vacuum of 3×10-5mbar pressure followed by annealing in air in the temperature range 573K - 873K. The crystallinity of the films were investigated using XRD. The films were found to be polycrystalline in nature and crystallizes in a cubic structure with preferred (222) orientation. The surface morphology was investigated for these films using Scanning Electron Microscope (SEM) and chemical composition of the films was estimated using EDS. The Optical transparency of these films was found to be varying with annealing temperature and at 673K the transmittance was found to be maximum. Thickness of the films was found to be 918nm. The optical band gap was also varying with annealing temperature. The PL emission spectra were taken at excitation wave length of 350nm. In2O3 thin films shown PL emission in the UV region at room temperature, which encourages development of nano scale devices in future.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91501706","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}

Here, analysis of an electrolyte material Ce0.8Gd0.2O1.9 (GDC20) is done. Five dense electrolyte samples are prepared at sintering temperatures of (1350, 1400, 1450, 1550 and 1600°C) were prepared and their properties like relative density, grain size and grain growth, ionic conductivity and power density were analyzed comparatively. Average density was found to be 89.93% and average grain size was in the range of 1.64μm-10.4μm.). Impedance result of all samples was examined at different temperatures (200°C-800°C) with frequency change from 1e7 hertz to 0.1 hertz for each working temperature. Exponential increase in ionic conductivity was observed in the temperature ranges of (500-800°C) for all five sample. Highest conductivity values were recorded for 1550°C sintered sample which was 8.479e-6 S/m at 200°C and 10.159 S/m at 800°C. Excellent power densities of were observed respectively. The best conductivities and power values were obtained for the 1550°C sample in the temperature range 600-800°C. Ionic conductivity values were exponentially higher in the higher temperature regions for all samples. Conventional SOFCs have an average efficiency of 70% and the use of GDC can lower the operating temperature hence increasing its usage in mining engineering, high-altitude power generation and usage in any treacherous environment.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81528242","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}

There are several unique optical properties that can make nano rods (NRs) potentially more appealing bioimaging probes. Hydrophobic core-shell-shell CdSe/CdS/ZnS nano rods (NRs) were synthesized by successive ion layer adsorption and reaction (SILAR) technique. Synthesized NRs (CdSe/CdS/ZnS) were made water dispersible by ligand exchange with thioglycolic acid and were conjugated with folic acid (FA) using EDC/NHS techniques for targeting human cancer cells expressing folate receptor (FR). The Folate receptor (FR) is ideally suited for this study because it is preferentially expressed with high binding affinity for folic acid in several cancers. In vitro cytotoxicity of the folate-conjugated CdSe/CdS-TGA and CdSe/CdS/ZnS-TGA NRs were investigated also by employing MCF-7 cells (Breast cancer cell line) through the 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. This assay shows that core-shell-shell (CdSe/CdS/ZnS) NRs are biocompatible than core- shell (CdSe/CdS) for targeting the cancer cells. The result of MTT viability assay shows that the percentage of living cells gradually decreases for CdSe/CdS rods where as in case of CdSe/CdS/ZnS rods ≥ 80% percentage of cell viability has been observed. These experiments confirms that FA conjugated NRs are preferentially internalized by MCF-7 tumor cells suggesting their potential utility as targeted fluorescent imaging agent for early stage cancer detection. The MTT cell viability assay indicated that covering the CdSe/CdS rods with ZnS shell reduces their cell toxicity.","PeriodicalId":13708,"journal":{"name":"International Conference on Advanced Nanomaterials & Emerging Engineering Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76399280","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}
