We have utilized a hydrothermal process to further refine the TiO2 structure to an 8nm diameter nanotube geometry and evaluated its effect on bone cell growth. Interestingly these small diameter TiO2 nanotubes, unlike the anodized TiO2 nanotubes, exhibit mostly multiwalled nanotube configuration with ...

Titanium dioxide nanotubes (TiO2-NT's) was synthesized using facile hydrothermal method. TEM micrograph shows that the synthesized TiO2-NT's had tubular structure with "hair-like" nanoscopic filaments with large specific surface area, which is needed to be a high performance photocatalyst. The saiz...

As an alternative, we report directly grown TiO2 nanotubes (synthesized on Fluorine doped Tin Oxide (FTO) via facile electrospinning technique) on carbon nanofibers, using hydrothermal method. The hierarchical branch type configuration has an intimate contact between the TiO2 nanotube and carbon ...
The titanate nanotube precursor was synthesized using the NaOH hydrothermal method27, which resulted in nanotubes with a diameter and length of approximately 18 and 220 nm (Fig. S1a and S1b), respectively. To wrap reduced graphene oxide (rGO) on the surface of the titanate nanotubes, electro...
