Optical modeling was applied for obtaining absorbance spectra and band gap values for different morphology of ZnO semiconductor. In optical modeling, the relative permittivity scalars of zinc oxide coral like nanorods were calculated using the Bruggeman homogenization formalism. ZnO nano rods (ZONRs) as a nucleus layer were fabricated on the Indium Tin Oxide (ITO) by chronoamperometry (CA) in a...

Multifilamentary Nb-Ti superconducting wires with heterogenous flux pinning nano-structures have been fabricated using artificial pinning center (APC) technology. Pinning centers were introduced into Nb-Ti filaments, consisting of Cu-Ni, Nb and Nb+Ti rods with the triangular arrangement and the volume fraction of 17 %. After final hot extrusions, the APC wires were drawn down over a high strain...

Anisometric DNA nanoparticles with precisely tailored size and shape are prepared by three-dimensional folding of – origami marked a fluorescent intercalating dye (YOYO-1), stabilised silica, dispersed in lyotropic chromonic liquid crystal (an aqueous solution disodium cromoglycate). Observations total internal reflection fluorescence microscopy indicate that the luminescent stable dispersion a...

The Research on Preparation of ZnO Nano-material and Photoelectric Devices Zinc Oxide (ZnO) is a wide band gap semiconductor material, which has a band gap of 3.37 eV at room temperature, its most important characteristic is the high exciton bounding energy of 60 meV. Based on these characteristics, ZnO has potential applications in short wavelength photoelectric devices. Since nanodevices such...

Monoclonal antibodies are used in numerous therapeutic and diagnostic applications; however, their efficacy is contingent on specificity and avidity. Here, we show that presentation of antibodies on the surface of nonspherical particles enhances antibody specificity as well as avidity toward their targets. Using spherical, rod-, and disk-shaped polystyrene nano- and microparticles and trastuzum...

We employ a planar metamaterial structure composed of a split-ring-resonator (SRR) and paired nano-rods to experimentally realize a spectral response at near-infrared frequencies resembling that of electromagnetically induced transparency. A narrow transparency window associated with low loss is produced, and the magnetic field enhancement at the center of the SRR is dramatically changed, due t...
