Summary form only given. The term "fullerenes" is applied to a wide class of polyatomic molecules of carbon Cn, where n ≥ 60, and solids based on them. Usually, however, fullerene molecule called C60, that is, a molecule consisting of sixty carbon atoms arranged on a spherical surface. The carbon atoms are located on the surface of the sphere at the vertices of pentagons (the Pentagon) and...
Rhomborhina Gigantea (R. Gigantea) was examined for its iridescent properties in its exocuticle. The iridescence was explained by the theories of the optical reflectors causing the structural colors and the concepts of cholesteric liquid crystals (CLCs). The exocuticle was examined for its optical properties through experiments of reflection and diffraction. Reflection spectra showed contrast results...
Novel nanobar Pt/ZnO thin films were prepared by the sol-gel technique associated with spin coating onto glass substrates. The as-prepared samples were annealed and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-vis absorption spectroscopy (UV-vis). The results indicate that the Pt/ZnO thin films consist of nanobars with diameters about 58 nm. By increasing the...
The titanium dioxide nanotubes (TiNTs) were directly fabricated from commercial P25 TiO2 via alkali hydrothermal transformation. The optimized synthesis, thermal and hydrothermal stability, and consequent optical properties of the titanate nanotubes were systematically studied. The TiO2 nanotubes were characterized by transmission electron microscopy. Dye-sensitized solar cells (DSSCs) were constructed...
