In this work, the PIL (poly ionic liquid)@TiO2 composite was designed with two polymerized liquid concentrations (low and high) evaluated for pollutant degradation activity benzene toluene. The results showed that (low)@TiO2 more active than (high)@TiO2 composites. photodegradation rate of toluene pollutants by composites obtained as 86% 74%, 59% 46%, respectively, under optimized conditions. b...

BACKGROUND Oral cavity is a doorway for a variety of products containing titanium dioxide (TiO2 ) nanoparticles (NPs) (nano-TiO2 ) such as food additives, oral healthcare products and dental materials. Their potential to penetrate and affect normal human oral mucosa is not yet determined. OBJECTIVES To evaluate the ability of nano-TiO2 to penetrate the in vitro reconstructed normal human bucc...

Cutting fluids can be used to cool workpieces at high cutting speeds and remove chips from zones. The effectiveness of may improved with the addition hybrid nanoparticle dispersion. This study evaluates an Al2O3-TiO2 as a fluid in turning operations. nano-cutting was prepared using one-step method computer numerical control (CNC) coolant concentrations up 4%. Utilizing air-assisted injected thr...

The scientific importance of nanocomposites are being increased due to their improvedproperties. This paper is divided into two parts. First, Al-Al2O3 nanocomposite wasproduced by using ball milling technique followed by cold compaction and sintering.Microstructure and morphology studies were done through SEM, TEM, and EDX anal-ysis on the produced powder. The mechanical properties of the produ...

Nanometer-sized titanium dioxide (TiO2) is an environmentally friendly optical semiconductor material. It has wide application value in many fields due to its excellent structural, optical, and chemical properties. The photocatalytic process of nano-TiO2 converts light energy into electrical or chemical energy under mild conditions. In recent years, the study and application of nano-TiO2 in the...

Although it is known that nano-TiO2or other nanoparticles can induce liver toxicities, the mechanisms and the molecular pathogenesis are still unclear. In this study, nano-anatase TiO2(5 nm) was injected into the abdominal cavity of ICR mice for consecutive 14 days, and the inflammatory responses of liver of mice was investigated. The results showed the obvious titanium accumulation in liver DN...
