OBJECTIVES To determine the capacity of human serum proteins to bind to titanium dioxide (TiO(2)) particles of different polymorphs and sizes. METHODS TiO(2) particles were mixed with diluted human serum, purified human serum albumin (HSA) or purified human serum gamma-globulin (HGG) solutions. After incubation at 37°C for 1 h, the particles were sedimented by centrifugation, and proteins in ...

This study presents the fabrication and improved properties of an AlGaAs/InGaAs metal-oxide-semiconductor pseudomorphic high-electron-mobility transistor (MOS-PHEMT) using liquid phase deposited titanium dioxide (LPD-TiO₂) as a gate dielectric. Sulfur pretreatment and postoxidation rapid thermal annealing (RTA) were consecutively employed before and after the gate dielectric was deposited to fi...

Titanium dioxide nanoparticles (TiO₂ NPs) are widely used in sunscreens, cosmetics and body implants, and this raises toxicity concerns. Although a large number of reports claim that they are safe to use, others claim that they induce reactive oxygen species formation and can be carcinogenic. In this study, the origins of toxic response to TiO₂ NPs were investigated by using Surface-enhanced Ra...

Titanium dioxide (TiO 2 ) is an abundant metal oxide, widely used in food industry, cosmetics, medicine, water treatment and electronic devices. TiO of interest for next-generation indium-free thin-film transistors ion-gated due to its tunable optoelectronic properties, ambient stability, solution processability. In this work, we fabricated films using a wet chemical approach demonstrated their...

The applications of nanomaterials specifically metal and nanoparticles in various medical industrial fields have been due to their unique properties compared bulk materials. A combination pharmacology nanotechnology has helped the production novel antimicrobial agents control resistant microorganisms bacteria fungi. oxides such as titanium dioxide (TiO 2 ), zinc oxide (ZnO), silver (Ag), copper...

In this research work, iron modified titanium dioxide photocatalyst was synthesized by the sol-gel method. The catalyst is characterized by FT-IR, XRF, and TGA techniques. Since the activity of Fe/TiO2 is highly affected by the loading of Fe, our major purpose of this work was focused on the role of this factor. Moreover, the effect of calcination temperature, which was also of h...

The bactericidal activity of conventional titanium dioxide (TiO₂) photocatalyst is effective only on irradiation by ultraviolet light, which restricts the applications of TiO₂ for use in living environments. Recently, carbon-containing TiO₂ nanoparticles [TiO₂(C) NP] were found to be a visible-light-responsive photocatalyst (VLRP), which displayed significantly enhanced antibacterial properties...

Abstract This study investigated the effects of adding titanium dioxide (TiO 2 ) and aluminium oxide (Al O 3 nanoparticles into Sn3.0Ag0.5Cu (SAC) lead-free solder alloy on thermal properties wettability. In comparison with SAC without addition nanoparticles, melting temperature is very similar comparable. The solidus in range 217.1 to 217.2 °C TiO Al nanoparticles. results shows that 0.25-1.0 ...

The potential eco-toxicity of nanosized titanium dioxide (TiO(2)), silicon dioxide (SiO(2)), and zinc oxide (ZnO) water suspensions was investigated using Gram-positive Bacillus subtilis and Gram-negative Escherichia coli as test organisms. These three photosensitive nanomaterials were harmful to varying degrees, with antibacterial activity increasing with particle concentration. Antibacterial ...

a r t i c l e i n f o A simple bilayer system consisting of TiO 2 and chitosan (CS) biopolymer has been fabricated and immobilized onto a glass plate. The deposition properties of TiO 2 powder were improved by adding epoxidized natural rubber (ENR 50) and phenol-formaldehyde resin (PF) in the coating formulation. SEM analysis indicated that the degraded ENR 50 acted as macro-pores forming agent...
