The coatings have been deposited by the dual-target magnetron sputtering on Si substrates and explored with the atomic force microscopy, scanning electron microscopy with energy dispersive spectroscopy, X-ray diffraction and nanoindentation. It has been found that the coatings have a nanocrystalline microstructure, are sufficiently textured, and represent a solid solution of the fcc-phase. The atomic concentration of elements in the initial target affects the structure and composition of the resulting coatings. It is shown that Ti-Zr-C coating with the lowest surface roughness (0.8 nm), the stoichiometric composition by carbon (50 at. % C) and the coarsest crystalline structure (15 nm) has the maximum values of the hardness of $sim 35$ GPa and Young's modulus of $sim 310$ GPa.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"80 1","pages":"01TFC25-1-01TFC25-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78656280","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 helps lower the operating temperature as well as protect the solid insulation from excess heat. However, due to the inherent meagre thermophysical and chemical properties of transformer oil, the demand for transformer oil based nanofluids becomes a binding need. Nanofluids exhibit innovative and unique properties because of the small size and high surface to volume ratio of the nanomaterials. This makes them a substantial material to be employed in the ongoing research related to the enhancement of thermal conductivity and other electrical properties of conventional fluids. Characteristics of nanoparticles like Brownian motion, interfacial resistance, morphology of suspended nanoparticles and their aggregating behavior has fascinated researchers for a long time now. In this paper, initially the nanomaterials are synthesized using the two-step method. The thermo-physical properties of nanofluids are studied, later on the conducting behavior of nanofluid is tailored by suitably choosing the nanoparticles. Subsequently, the thermal conductivity of nanofluid is discussed taking three different types of conducting and nonconducting metal oxide nanoparticles $(TiO_{2;}Al_{2}O_{3;}Fe2O_{3})$ in terms of their concentration. The prepared nano-fluids are used for calculating insulation resistance, dissipation factor and thermal conductivity in the temperature range of $20^{circ}{C}$ upto $80^{circ}{C}$ with a step size increase of $20^{circ}{C}$. The results reveal that these properties of the base fluid get enhanced with the use of nanoparticles resulting in the efficacy enhancement of insulation oil.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"71 1","pages":"02IT06-1-02IT06-5"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87806668","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 results of powder X-ray diffraction, scanning electron microscopy, thermo-gravimetrical analysis and luminescence spectroscopy studies have been discussed from viewpoint of the studied materials application in white light emitting diodes. It was found that glass-ceramics consist mainly of amorphous phase with inclusion of potassium bismuth molybdate micro/nanocrystals. The glass transition temperatures were determined as 333, 340 and 327°C for initial glass, Eu-doped glass and glass-ceramics studied, respectively. The initial glass reveals wide luminescence band that lies in 500 -- 750 nm spectral range under excitation at 473 nm at room temperature. Europium-doped glass and glass-ceramics samples mainly reveal luminescence bands of $f-f$ transitions in $mathrm{E}mathrm{u}^{3+}$ ions. The broadening of $mathrm{E}mathrm{u}^{3+}$ emission bands in glassceramic samples was ascribed to migration of some rare-earth ions from crystalline component into glass host.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"53 1","pages":"01NSSA11-1-01NSSA11-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74951636","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 comparative contribution of each micro-nanostructural morphological components of the eggshell (mamillary, palisade, and crystalline layers) in the integral yield of carbon dioxide (CO2) as a product of eggshell thermal destruction at specific temperatures was shown. The activation energies (Ea) for individual shell components were calculated.
