“…It is a common dye in powders, foundations, eye shadows, blushes, and nail polishes. As it inhibits the penetration of solar radiation, it is also used as a filter in sunbathing cosmetics (Liu et al 2004;Saurabh et al 2022;Zhang et al 2011). Due to such a wide use of metallic titanium and its alloys and compounds, it is necessary to constantly monitor the environment in terms of contamination with this element.…”

We report the use of carbon nanotubes as a material for the preparation of an electrochemical sensor that acts as a substrate for film metal electrodes used in stripping voltammetry. The sensor is based on a mixture of multiwall carbon nanotubes, glassy carbon spherical powder, and epoxy resin. The properly selected composition of the sensor made it possible to obtain a new substrate, competitive in relation to glassy carbon, for creating film metal electrodes. In this work, the proposed new sensor was used to determine the trace amounts of Ti(IV) on the lead film electrode. Measurements were carried out with in situ mode in an acetate buffer by adsorption stripping voltammetry with the use of cupferron as a complexing agent. Linear response to Ti(IV) ions in the concentration range of 7 × 10–10–7 × 10–8 mol L−1 and the limit of detection (LODs) 2.4 × 10–10 were obtained, respectively. These promising results revealed that a mixture of carbon nanotubes, epoxy resin, and spherical glassy carbon powder used for the determination of titanium ions on PbFE might represent an important addition to existing electrochemical sensor technologies. The proposed procedure was successfully used as a new and powerful analytical tool for determination of Ti(IV) in horsetail extracts.

“…It is attributed to a thin film of TiO2 (around 5-6 nm) that grows on the surface. However, the film also acts as an electrical insulator and results in a high contact resistance and ohmic losses [2]. The low electric conductivity of titanium metals is thus a critical issue to be solved for those scenarios.…”

In fuel cells, electrolysis cells, etc., titanium have been widely employed due to the high corrosion resistance achieved by the oxide film. But it also leads to low electrical conductivity and reduces the cells efficiency significantly. To illuminate how to improve the conductivity of titanium alloys, first-principles calculations merged with Boltzmann transport equation and Schottky-Mott theory is adopted to investigate the doping effects of thirty-seven elements on the electronic transport property. The results indicate the low electrical conductivity of TiO2 is attribute to the strong ionic bond of Ti-O. Nb, Ta, Sb and Zr can enhance the conductivity to above 1.0×103 S∙cm-1, which can also make the Schottky barrier decline from 1.05 eV to below 0.4 eV. That is mainly due to the Fermi level shifting and the stronger covalent bond formed between the impurity and O atoms. This work also investigated the effect of doping ratio on the conductivity. The covalent bond between impurity and O atoms is found to increase at a higher doped ratio. That results in the extension of the unoccupied state of the valence band maximum and conduction band minimum to the forbidden gap, which further leads to the reduction of the band gap.

“…Titanium alloys are commonly used in the manufacture of aircra engine pressurized components, and are also important structural components for rockets, missiles, and other aircra. [1][2][3] Titanium alloys have good corrosion resistance and fatigue resistance, good biocompatibility, and have also gained wide popularity in the biomedical eld. Titanium alloys are now commonly used to manufacture medical surgical instruments, such as scalpels, and surgical forceps.…”
