Summary: Titanium dioxide nanotubes (TNTs) grown on the surface of titanium implants play a significant role in preventing tissue infection and implant failure. This study investigates the role of different counter electrodes in the formation of TNTs with varying shapes and surface properties. The use of platinum and graphite cathodes results in circular TNTs, while stainless steel cathode leads to hexagonal-shaped tubes with particle debris on the surface. The surface microstructure of TNTs affects their roughness, hydrophilicity, and ability to facilitate the growth of bone-forming apatite during osseointegration.

Summary: The electrochemical, structural, and biological properties of self-organized amorphous and anatase/rutile titanium dioxide (TiO2) nanotubes deposited on Ti-35Nb-4Zr alloy through anodization-induced surface modification were investigated. The study found that anatase TiO2 exhibited higher surface corrosion resistance and cell viability compared to amorphous TiO2, indicating the importance of TiO2 nanotube crystallization in the material's electrochemical behavior and biocompatibility.

Summary: Titanium dioxide nanotubes (TiO2 NTs) were synthesized by electrochemical anodizing of pure titanium in glycerol-water solution with ammonium fluoride. The properties of the NTs, including diameter and length, were controlled through the anodization time. Characterization techniques like SEM, XPS, XRD, Raman spectroscopy, and EIS were used to analyze the synthesized NTs. The results showed that the internal diameter of the NTs could be adjusted from 30 to 130 nm, while the length increased progressively up to a maximum of approximately 3.32 μm after 90 minutes. XPS analysis confirmed the formation of TiO2 with an oxidation state of +4, and XRD and Raman spectroscopy revealed a mixture of anatase and rutile phases. The TiO2 NTs exhibited n-type semiconductor behavior according to Mott-Schottky analysis. Photocatalytic testing of the TiO2 NTs demonstrated that the length of the NTs had a significant impact on the photocatalytic efficiency, with NTs of 2.55 μm length showing an excellent efficiency of approximately 79.69% with a kinetic rate of 0.0051 min-1. Increasing the solution pH from 3 to 12 resulted in an increase in degradation efficiency from 31.6% to 93.1%.

Summary: In this study, the possibility of using anodization to obtain TiO2 nanotubes was evaluated, and the surface chemical composition was determined using X-ray photoelectron spectroscopy. The results showed that the anodization process resulted in nanotubes with larger diameters and thicknesses, and the oxide layer contained different oxidation states of Ti, Zr, and Mo elements.

Summary: This study investigated the formation and crystallization of a nanostructured oxide layer on the surface of Ti-35Nb and Ti-35Nb-5Ta samples using heat treatments. The results showed the formation of anatase within a certain temperature range, with a transformation to rutile at higher temperatures. A doped Nb2O5 phase was also detected at higher temperatures. The presence of Ta in the Ti-Nb-Ta substrate supported the crystallization of anatase and (Nb)2O5 at lower temperatures compared to the Ti-Nb substrate.

Summary: The study aimed to compare the surface characteristics and cytotoxicity of anodic TiO2 nanotubes on ECAP-processed CP-Ti and CG-Ti substrates, showing superior application of anodic nanotubes on ECAP-ed CP-Ti. UFG-Ti samples had smaller diameter and longer nanotubes compared to CG-Ti, with CG-Ti nanotubes being more hydrophilic. Enhanced cell viability and proliferation were achieved on ECAP-ed CP-Ti anodic TiO2 nanotubes.

Summary: This paper presents a simulation model of TiO2/Ti film to study the kinetics of the laser-induced titanium oxidation process, finding that the laser-induced Mott potential is a crucial factor in determining the final oxidation degrees. An effective way to improve laser machining resolution is to apply threshold power and short-duration pulse laser irradiation on the film repetitively.
