In this work, an ultra-thin plasmonic metamaterial nanostructure absorber is simulated using the finite difference time domain method in visible and near-infrared regions. A periodic square titanium-silica cap coated with glass medium mounted on top of a silver substrate. The presence host enhances absorption bandwidth by 276%. With almost perfect metal–insulator-metal absorber, over 90% absorb...
monometallic and bimetallic ni and co catalytic nanoparticles supported on titanium dioxide (rutile phase) substrate were prepared by wet impregnation method. these nanoparicles were used as catalysts for synthesis of multiwalled carbon nanotubes (mwcnts) from acetylene decomposition at 700°c by the catalytic chemical vapor deposition (ccvd) technique. the nanomaterials (catalyst and cnts) were...
Understanding cell-biomaterial interactions is critical for the control of cell fate for tissue engineering and regenerative medicine. Here, cerium oxide nanoparticles (CeONPs) are applied at different Ce4+/Ce3+ ratios (i.e., 0.46, 1.23, and 3.23) to titanium substrate surfaces by magnetron sputtering and vacuum annealing. Evaluation of the cytotoxicity of the modified surface to cultured rat b...
The microstructure and properties of a silicon coating on titanium nickelide substrate were studied to assess the possibility using such improve biocompatibility medical implants. with thickness 4.0±0.5 microns was applied TiNi molecular beam epitaxy unit. had submicrocrystalline structure crystallite size 0.1...0.2 microns, developed surface, high crack resistance.
Titanium tungsten carbide (TiWC) coatings are deposited by a combined high-power impulse and dc magnetron co-sputtering (HiPIMS/DCMS) technique. No external heating is applied during deposition phase, instead, the thermally driven adatom mobility substituted heavy ion irradiation. DCMS sources equipped with titanium targets provide constant neutral fluxes to establish predominant coating struct...
