Multilayer coating structure comprising a copper (Cu) layer sandwiched between titanium dioxide (TiO2) were demonstrated as a transparent heat reflecting (THR) coating on glass for energy-saving window application. The main highlight is the utilization of Cu, a low-cost material, in-lieu of silver which is widely used in current commercial heat reflecting coating on glass. Color tunable transpa...

Titanium dioxide (TiO2) is increasingly widely used in industrial, commercial and home products. TiO2 aggravates respiratory symptoms by induction of pulmonary inflammation although the mechanisms have not been well investigated. We aimed to investigate lung inflammation in rabbits after intratracheal instillation of P25 TiO2. One ml of 10, 50 and 250µg of P25 TiO2 was instilled into one of the...

Inhaled ultrafine titanium dioxide (UF-TiO2) particles cause pronounced pulmonary inflammation, in contrast to fine TiO2. Previous studies provide evidence for the production of reactive oxygen species by alveolar macrophages, after overloading with UF-TiO2 particles and cytotoxicity of UF-TiO2 in rat lung alveolar macrophages. UF-TiO2 also causes pulmonary fibrosis and lung tumors in rats. UF-...

Titanium dioxide (TiO2), a semiconducting material, is a well-known photocatalyst. A nanoparticle (NP) of TiO2 also demonstrates photocatalytic activity. Photo-irradiated TiO2 NPs induce the formation of various reactive species, leading to the damage of biomacromolecules. These reactive species include h+, either free or trapped hydroxyl radicals (OH⋅), superoxide (O2), hydrogen peroxide (H2O2...

Application of titanium dioxide (TiO2) as a photocatalyst has presented a promising avenue for the safe photocatalytic degradation of pollutants. Increasing levels of the release of pharmaceuticals in the environment and formation of the intermediates during their degradation may impose health and environmental risks and therefore require more attention. Photocatalytic degradation of acetylsali...

Titanium dioxide (TiO2) nanoparticles are manufactured worldwide in large quantities for use in a wide range of applications including pigment and cosmetic manufacturing. Although TiO2 is chemically inert, TiO2 nanoparticles can cause negative health effects, such as respiratory tract cancer in rats. However, the mechanisms involved in TiO2-induced genotoxicity and carcinogenicity have not been...

Background & Aims of the Study: The heterotrophic bacteria are widely used as a water microbial pollution index for drinking water. The aim of this study was to investigate the effect of metallic nanoparticles such as Zero Valent Iron (ZVI), Titanium dioxide (TiO2) and Zinc oxide (ZnO) on Heterotrophic Bacter...

Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...

In recent years, photocatalytico oxidation processes with ultra violet (UV) radiation and semiconductor photocatalyst like titanium dioxide (TiO2) and zinc oxide (ZnO) have gained immense research interest as an effective wastewater purification method because of its efficacy in decomposing and mineralising the hazardous organic pollutants as well as the opportunity of utilizing the solar UV an...

This study addresses the preparation and characterization of hybrid films prepared from Titanium dioxide (TiO2) Pickering stabilized acrylic polymeric dispersion as well as their bacterial inactivation efficiency under sunlight irradiation. Complete bacterial inactivation under low intensity simulated solar light irradiation (55 mW/cm(2)) was observed within 240 min for the films containing 10 ...
