Effect of TiO2 Rutile Additive on Electrical Properties of

Mar 16, 2016 · Abstract. Polypyrrole/titanium dioxide nanocomposite (PPy/TiO 2) was synthesized by in situ chemical polymerization of pyrrole (Py) monomer in colloidal suspension of TiO 2 rutile. TEM and SEM images show that the TiO 2 is covered by PPy forming a core-shell structure. The PPy/TiO 2 core-shell will create junction and bring in an inversion layer on the PPy-shell surface. Formation of high performance nanostructured ZnO thin Dec 01, 2020 · Then, ZnO nanoparticles are produced by heating Zn thin films in the open air at temperatures of 300, 500, 700, 900, and 1100°C for 2 hours. XRD analysis of these films shows that except for the 1100-ZnO sample, which has a cubic structure, the rest of the films confirm the hexagonal crystal structure of the Wurtzite.

Reaction of sulfur and selenium with elemental or ionic metals in liquid ethylenediamine at room temperature produced metal chalcogenides ME (M = Cu, Sn, Co 2+, Ni 2+, Mn 2+, or Pb 2+; E = S or Se), Ag 2 E, M 2 E 3 (M = Bi or Sb). The results showed that the products had a range of crystalline sizes from 10 to 100 nm.
