Rutile titanium dioxide nanoparticles (nTiO2) were weathered in field soil at 0, 100, 200, and 400 mg Ti/kg for four months. Two types of nTiO2 with different surface coatings (hydrophilic hydrophobic), uncoated (pristine), the untreated control included. Thereafter, carrot seeds (Daucus carota L.) sown those soils grown a growth chamber 115 days until full maturity. A comparison was made betwe...
The influence of surface charge of nanomaterials on toxicological effects is not yet fully understood. We investigated the inflammatory response, the acute phase response and the genotoxic effect of two different titanium dioxide nanoparticles (TiO2 NPs) following a single intratracheal instillation. NRCWE-001 was unmodified rutile TiO2 with endogenous negative surface charge, whereas NRCWE-002...
The possibility to recover the titanium dioxide (TiO2) nanoparticles synthesized in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles by compressed CO2 was investigated. UV-Vis study showed that TiO2 nanoparticles could be deposited from the reverse micelles by the dissolved CO2. The nanoparticels were prepared and characterized by the transmission electron microscopy (TEM). The re...
Titanium dioxide nanoparticles play a crucial role in the production of hydrogen gas evolution. Among four polymorphic phases TiO2 (anatase, rutile, brookite, and (B)), anatase phase shows good photo activity catalytic applications. We prepared single anatasephase usinga facile one-step ionothermal method with existence 1-(3,6-dioxa heptane) 3-methyl imidazolium methane sulfonate IL[DOMIMS]. Th...
