Highly-ordered TiO2 nanostructures have been successfully fabricated by anodic oxidation method on the surface of pure titanium and Ti film deposited on the Si substrates using 20 V of the DC voltage in 0.5% HF electrolyte. X-ray diffractometer (XRD), Raman spectroscopy and field emission scanning electron microscope (SEM) were used to characterize the transformations of morphologies and structures on the TiO2 nanostructures. The experimental results showed that the final morphologies of the nanostructures were time-dependent. The tube architectures were firstly fabricated, and with the increase of the oxidation time, the tube morphologies were ruined and the rod-like morphologies were formed. When the Ti films on the Si substrates were anodized, a new kind of porous nanostructures was formed on the surface of the Ti foils, which are different to the previous reports. The formation mechanisms of these nanostructures were also briefly discussed.

This study investigated the effects of various titanium nanoparticles (TiONPs) on the structure, function, and trophic levels of the wheat rhizobiome. In contrast to the typically toxic effects of small nanoparticles (~10 nm), this research focused on molecular TiO and larger nanoparticles, as follows: medium-sized (68 nm, NPs1) and large (>100 nm, NPs2). The results demonstrated significant yet diverse impacts of different TiO forms on the rhizosphere microbiota.

Nanocrystalline TiO is a perspective semiconductor gas-sensing material due to its long-term stability of performance, but it is limited in application because of high electrical resistance. In this paper, a gas-sensing nanocomposite material with p-p heterojunction is introduced based on p-conducting Cr-doped TiO in combination with p-conducting CrO. Materials were synthesized via a single-step flame spray pyrolysis (FSP) technique and comprehensively studied by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) specific surface area analysis, transition electron microscopy (TEM), energy dispersive X-ray (EDX) spectroscopy, X-ray photoelectron spectroscopy (XPS), electron paramagnetic resonance (EPR), and Raman spectroscopy.

The surface charge of metal oxides is an important property that significantly contributes to a wide range of phenomena, including adsorption, catalysis, and material science. The surface charge can be predicted by determining the isoelectric point (IEP) of a material and the pH of a solution. Although there have been several studies of the IEP of metal oxide (nano)particles, only a few have reported the IEP of metal oxide films.
