Time-Dependent Hydrothermal Synthesis of TiO2 in the Presence of Zn2+: Effects on Photoconductivity

  • Tilemachos Georgakopoulos,
  • Georgios Samourgkanidis,
  • Nadia Todorova,
  • Christos Trapalis and
  • Katerina Pomoni

Titanium dioxide nanoparticles were synthesized via hydrothermal treatment of tetrabutyl titanate in sulfuric acid, with controlled reaction times (10 h and 24 h) and zinc sulfate as a modifier. XRD confirmed exclusive formation of the anatase phase,...

Friction and Wear Performance of Carbon Nanotubes Reinforced Co-Based Atmospheric Plasma-Sprayed Coatings

  • Ilias Georgiopoulos,
  • Dimitra Giasafaki,
  • Dia Andreouli and
  • Chara I. Sarafoglou

Atmospheric plasma spraying was used to create composite coatings employing mixed alloy matrices supplemented with carbon-based solid lubricants as feedstock materials. The current study’s goal was to examine the tribological properties of thes...
