[ 5 ] Confi nement of plasmon modes to a surface of metal nanostructures under the constraints imposed by the fi nite boundaries of the nanostructure alters their dispersion, only allowing for discrete solutions. In the quasi-static limit, where the wavelength of the excitation light is much larger than the size of the nanostructure, the nan...

Current applications of carbon-based supercapacitors are limited by their low energy density. One promising strategy to enhance the energy density is to couple metal oxides with carbon materials. In this study, a porous MnCo2O4.5 nanoneedle/carbon aerogel hybrid nanostructure was synthesized by assembling MnCo2O4.5 nanoneedle arrays on the surface of channel walls of hierarchical porous carbon ...

A novel class of nanostructured Zr50Cu50 (%at.) metallic glass films with superior and tunable mechanical properties is produced by pulsed laser deposition. The process can be controlled to synthetize a wide range film microstructures including dense fully amorphous, amorphous embedded nanocrystals nano-granular. unique self-assembled nano-laminated atomic arrangement characterized alternating ...

beryllium  oxide  (beo)  nanopowder  was  synthesized  using  sol-gel method  and  the  effects  of  changes of  chemical  reagents  were investigated.  because  of  tissue  equivalence  and  other  outstanding thermoluminescence  (tl) properties of  the bulk material  in x and γ dosimetry, the applicability of this nanostructure in tl dosimetry was studied  following  irradiation to  the 137 c...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.

the aim of this work is to synthesize and investigate the performance of yttria-doped zirconia solgelcoatings in the chemical corrosion prevention of zircaloy-4 (zirconium alloy) in a 1 n h2so4environment. the influence of four different molar ratios of water to alkoxide, namely 1, 4, 12, and20, on the coating quality and its corrosion prevention performance was investigated. differentialtherma...
