SLOWING COMBUSTION AND STRENGTHENING PET WITH TITANIUM DIOXIDE NANOPARTICLES

Aggregation and Toxicology of Titanium Dioxide Nanoparticles

In their study of inhalation exposure of titanium dioxide particles, Grassian et al. (2007) presented a transmission electron micrograph (TEM) (their Figure 2A) as an image of “dispersed” TiO2 nanoparticles. Yet, the TiO2 nanoparticles in this TEM do not appear to be dispersed. There is clear evidence of self-organization of the nanoparticles into distinct assemblages, separated by relatively l...

Toxicity and interaction of titanium dioxide nanoparticles with microtubule protein.

Titanium dioxide (TiO2) nanoparticles (NPs) are widely used in several manufactured products. The small size of NPs facilitates their uptake into cells as well as transcytosis across epithelial cells into blood and lymph circulation to reach different sites, such as the central nervous system. Different studies have shown the risks that TiO2 NPs in the neuronal system and other organs present. ...

[Titanium dioxide nanoparticles: occupational exposure limits].

Titanium dioxide (TiO2) is produced in Poland as a high production volume chemical (HPVC). It is used mainly as a pigment for paints and coatings, plastics, paper, and also as additives to food and pharmaceuticals. Titanium dioxide nanoparticles are increasingly applied in cosmetics, textiles and plastics as the ultraviolet light blocker. This contributes to a growing occupational exposure to T...

Mucin Secretion Induced by Titanium Dioxide Nanoparticles

Nanoparticle (NP) exposure has been closely associated with the exacerbation and pathophysiology of many respiratory diseases such as Chronic Obstructive Pulmonary Disease (COPD) and asthma. Mucus hypersecretion and accumulation in the airway are major clinical manifestations commonly found in these diseases. Among a broad spectrum of NPs, titanium dioxide (TiO(2)), one of the PM10 components, ...
