In present study, a simultaneous electrospinning and electrospraying (SEE) process was employed to produce microclusters of TiO nanoparticles and interlock them in nanofibrous network. The photocatalytic composite membranes (PCMs) were fabricated by electrospraying TiO nanoparticle suspension into microcluster form that dispersed and entrapped within nylon-6 electrospun fiber membrane. Three PCMs membrane with TiO content of 52.0, 83.6, and 91.7wt.% were successfully fabricated. The membrane consisted of TiO microclusters, ranging in sizes from around 0.3 to 10μm, distributed uniformly within the nylon-6 nanofibrous network. PCMs photocatalytic activity against Methylene Blue (MB) in aqueous solution showed more than 98% MB removal efficiency after 120min of photocatalytic oxidation (PCO) for all PCMs. For PCM with the highest TiO content tested for 5 PCO cycles, it was found that most of their TiO content remained incorporated within the nanofibrous structure. The concept of nanoparticles clusters entrapment with SEE fabrication employed here provide a simple and effective method for reducing detachment of nanostructure phase from nanocomposite membrane.

Metal oxide semiconductor (MOS) hydrogen sensors offer advantages, such as high sensitivity and fast response, but their challenges remain in achieving low-cost fabrication and stable operation at room temperature. This study investigates Nb-doped TiO (NTO) thin films prepared via a one-step micro-arc oxidation (MAO) with the addition of NbO nanoparticles into the electrolyte for room-temperature hydrogen sensing. The characterization results revealed that the incorporation of NbO altered the film's morphology and phase composition, increasing the Nb content and forming a homogeneous composite thin film.

Perfluorooctanoic acid (PFOA) and nano-titanium dioxide (nano-TiO₂) are widely used in industrial applications such as manufacturing and textiles, and can be released into the environment, causing toxicity to marine organisms. To study the effects of these pollutants on the gonadal development, we exposed the males of Mytilus coruscus to varying PFOA concentrations (2 and 200 μg/L) alone or combined with nano-TiO (0.1 mg/L, size: 25 nm) for 14 days.

Titania (TiO) is one of promising photo catalysts for its high ability to resistant photo corrosion and environmental friendliness, but its photocatalytic activity is too low to be used in industry. To find an approach to solve this problem, graphene oxide (GO), tungsten trioxide (WO) and TiO composite with hollow mesoporous structure was prepared by a two-step spray drying method. The composite was used as raw material to constitute a membrane onto ITO glass to form a membrane photo-anode.

Low-loss microwave dielectrics are of significant importance for the miniaturization and integration of microwave devices. In this paper, the ceramics of nominal composition MgTiO ( = 3-6) are synthesized, and the correlations among their phase compositions, defect behaviors, and microwave dielectric properties are systematically investigated. The analyses indicate that the MgTiO ceramics are a biphasic system consisting of hexagonal ilmenite-structured MgTiO and cubic spinel-structured MgTiO.
