UV-Visible spectra display a dual peak line shape which can be ascribed to the transverse dipole resonance (longer wavelength) and the transverse quadrupole resonance (shorter wavelength) of silver nanostructures, respectively. SEM image shows the morphologies and aspect ratios of the synthesized silver nanowires after purification by acetone centrifugation process. The diameters of most of the silver nanowires are in the range of 90–100 nm, and lengths of 1–3 μm. Consequently, asprepared Ag nanostructres with suitabe aspect ratio, satisfactory surface plasmon resonance (SPR) and conductive properties can be considered for designing new plasmonic-semiconductor composite to enhance solar energy conversion efficiency of Photoelectrochemical (PEC) and Photovoltaic (PV) cells.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"14 1","pages":"03NE14-1-03NE14-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91196243","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 ability to improve mechanical properties with the use of smaller volume fraction of reinforcements while keeping density low makes magnesium nanocomposites an attractive choice for biomedical applications. The addition of nanoparticles to magnesium assists in enhancing multiple engineering properties that are critical for its widespread use and are superior to that exhibited by conventional micron-size particles containing composites. Metal matrix composites reinforced by NPs are very promising materials, suitable for a large number of applications. These composites consist of a metal matrix filled with NPs featuring physical and mechanical properties very different from those of the matrix. The NPs can improve the base material in terms of corrosion resistance and good biocompatibility, damping properties and mechanical strength.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"28 1","pages":"04NB14-1-04NB14-5"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80435789","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}

For this purpose, the active centers of carbons were simulated within the density functional theory method. It was shown that all proposed models derived from the honeycomb structure of coronene have edge double C=C bond as an active center of the surface. With an increase in the size of the carbon models, such bonds become shorter, this increases the bond order and, simultaneously, the affinity for the addition reactions becomes significant. The symmetry of models, the defects of the structure or vacancies of carbon atoms do not effect on the length of the edge double C=C bonds. We calculated the reaction thermodynamic for the interaction of C54H18 cluster with dibromine. At these processes, the functional oxygen-containing groups have a certain impact only on the nearest neighboring carbon bonding. The calculation showed that the bromine molecules attack the edge double C=C bond. This way is more energetically favorable than the substitution of hydrogen for bromine.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"36 1","pages":"01PCSI02-1-01PCSI02-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81105452","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 necessity to improve technologies for porous ammonium nitrate generation is shown with aim to form meso- and macropores on the surface of the granule and inside it. The internal and surface structure of granules is studied under different thermal treatment regimes. The results of experimental research allow to define the temperature of heat transfer agent in the working area of the vortex granulator during the proper time and to implement this index to calculate heating up kinetics and granule dehydration. Specification of the heat transfer agent's temperature index lets to perform computations, determining minimum time for granule drying, in order to avoid its unintended overheating and core destruction.","PeriodicalId":6516,"journal":{"name":"2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP)","volume":"95 1","pages":"03NE09-1-03NE09-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80654729","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}

First, the adsorption efficiency and cumulative release percentage of newly created HBsAg-AuNC formulations were characterized. Then, their adjuvant responses in RAW 264.7 macrophages were systematically analysed in vitro by real time cell analysis system, flow cytometry, confocal microscopy, and ELISA. We have observed that HBsAg-AuNC vaccine formulations were stable and have uptaken easily by macrophages but not into the nucleus, and triggered the immune maturation of RAW 264.7 cells.
