Summary: In this work, the optical properties of a bamboo-type TiO2 nanotube photonic crystal with a metallic coating are analyzed using the finite-difference time-domain method, and the occurrence of Tamm plasmons in the absorption spectrum is predicted. The integral absorption of the gold-, titanium-, and titanium nitride-coated photonic crystals in the wavelength range of 450-600 nm is calculated, and it is found that the titanium nitride-coated structure exhibits the maximum integral absorption.

Summary: The feasibility of electrochemical detection of 2,4,6-trinitrotoluene (2,4,6-TNT) using TiO2 nanotubes synthesized through electrochemical anodization of Ti was explored. The study found that the anodic TiO2 nanotubes exhibited good electrochemical sensing properties and could distinguish different compounds based on reduction peaks. Further research is suggested to enhance the efficacy of TiO2 nanotube arrays for the electrochemical reduction of explosive compounds by introducing metal dopants, quantum dots, or vacancy engineering.

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: A GO/TiO2 electrode was prepared by depositing graphene oxide (GO) on a titania plate through a simple anodization method. The morphology and structure of the TiO2 and GO/TiO2 electrodes were characterized using various techniques. The results showed that GO nanoparticles were successfully formed on the TiO2 substrate, with a thickness of approximately 300 nm. The synthesized GO/TiO2 nanotube electrode exhibited a bandgap of 3.052 eV. The effect of pH, current, and degradation time on the COD degradation and energy consumed was investigated using response surface methodology. At optimized parameters, a COD degradation of 57.61% and energy consumption of 15.00 kWh/m(3) were achieved. The electroplating effluents degradation mechanism was found to involve center dot OH radicals.
