TiO2 has strong photocatalytic activity, which can oxidize and decompose impurities on surfaces and in the air. Therefore, TiO2 is used as an additive in the self-cleaning coating and paint industries. In this work, SiO2 is used in the TiO2/SiO2 mixture as the nucleus to homogenize the dispersion components. TiO2 and SiO2 nanoparticles are synthesized by the sol-gel method combined with ultrasound that suits the size range of 10-30 nm.

In this study, the TiO2 passive layer was formed on a pure titanium substrate by simple oxidation in an aqueous solution of H2O2 35 wt.%. In order to determine the appropriate time for the oxidation of the pure titanium substrate, the corrosion rate of the metal in the solution of H2O2 was investigated. The electrochemical behaviour of the TiO2 passive layer on the Ti substrate was investigated in Hank’s solution at 37.5°C.

In this work, gold nanorods (AuNRs) with well-controlled aspect ratios were prepared using a modified seedgrowth method and covered by TiO2 layers through the hydrothermal reaction to improve stability. Integrating TiO2 with plasmonic rod-like gold nanoparticles could enhance their photo activity by the local surface plasmon resonance (LSPR) effect. AuNRs aspect ratios were controlled by varying the amount of seed solution, reducing agents, surfactant (CTAB), and titanium (IV) but oxide.

The alkyde paint has high gloss, hardness, and flexibility, good color retention of coating film. It is good for adhesion with wood, metal and others. However, there have been very few researches on alkyde paints in Vietnam recently. This paper is aimed at studying the influence of rate of Beckosol 6501-80 binder and solids powder as titanium oxide R, Lithopone, CaCO3 to quality of surface film of Alkyde paint.

The organic dyes have beenwidely used in the textile industry for last decades. Nowadays, they have also known as toxic and polluted compounds because of their high persistence in soil sediments and water resources. These chemicals may be degraded to the carcinogens and toxic products under sunlight irradiation, affecting aquatic life and ecosystem.

The solution plasma process (SPP) is a revolutionary approach for production of nanomaterials employing plasma discharge in liquid. The SPP can quickly deionize metal into the neutral state in the absence of a reducing agent. Selenium nanoparticles are created in solution plasma in this investigation.

Metal-oxide nanoparticles have reached a wide range of applications in the last ten years. Titanium dioxide nanoparticles stand out with their unique crystal structure and near-perfect physical and chemical properties at nanoscales (crystal size between 10–100 nm). It has created many applications with its white pigment, semiconductor state, and effective photocatalytic properties, but the synthesis of these nanoparticles is very damaging to nature.

Topographic essential synthesis of nanomaterials by adjusting easy preparatory factors is an effective way to improve a variety of nanostructured materials. The SILAR technique is used to evaluate the manufacturing samples of MoO3, TiO2, and MoTiO5 nanostructures. These nanostructures of MoO3, TiO2, and MoTiO5 are used as electrode materials in photovoltaic systems. The link between photoelectrochemical characteristics and MoO3, TiO2, and MoTiO5 nanostructures is studied in depth.

The use of nanoparticles (NPs) has increased in recent years and consequently they are being released into the environment. The final destination of most NPs is the aquatic environment due to washing up by rain waters. Fish (n = 120) were exposed to different concentrations (0, 1, 5, and 25 mg/L) of aluminum-oxide (Al2O3), copper-oxide (CuO), and titanium-dioxide (TiO2) NPs for 14 days and 14 days of depuration period (no NP in water). Following NP exposures, activities of Na,K-ATPase, Mg-ATPase, Ca-ATPase, and acetylcholinesterase (AChE) in the brain and muscle were measured.

The use of multiwalled carbon nanotubes (CNTs) in sol-gel synthesized titanium dioxide (TiO2) photocatalysts as templates was systematically studied. CNTs have high oxidative thermal stability and the controlled removal of CNTs can be achieved at lower temperatures under air flow by the use of Na, Fe, and Co as a catalyst. These catalysts helped to reduce the oxidation temperature of CNTs; thus anatase phase was achieved without significant sintering.

Titanium dioxide/phthalocyanine (TiO2/Pc), TiO2/fluor containing phthalocyanine (TiO2/FPc), and TiO2/fluor containing cobalt phthalocyanine (TiO2/FCoPc) had been successfully fabricated by a simple combination of phthalocyanines obtained by insitu synthesis on the surface of TiO2 nanofibers prepared by electrospinning. Scanning electron microscopy micrographs and X-ray diffraction analysis indicated that the phthalocyanines uniformly immobilized on the surface of TiO2 nanofibers.

The thermodynamics involving the dielectric constant and Gibb's free energy of oxide formation at the Al/TiOx and TiOx/TiOy interfaces play a pivotal role in the associated switching mechanism. The spatial variability of the operating voltage across these devices is found to be as low as 8%. These findings pave the way for low power, low cost, and high density data storage applications.
