an investigation was initiated to examine the effects of nanoscale titanium dioxide particles on plant growth and development. in view of the widespread cultivation of canola in iran and in other parts of the globe and in view of the potential influence of titanium on its growth, this plant was chosen as the model system. canola seeds were separately treated with different concentrations of nan...

Pulmonary toxicology studies in rats demonstrate that nanoparticles administered to the lung are more toxic than larger, fine-sized particles of similar chemistry at identical mass concentrations. The aim of this study was to evaluate the acute lung toxicity in rats of intratracheally instilled pigment-grade TiO2 particles (rutile-type particle size = approximately 300 nm) versus nanoscale TiO2...

Titanium dioxide (TiO2) nanoparticles (NPs) are widely used in paints, food colorants, cosmetics, pharmaceuticals, and many other applications. Due to their high refractive index, TiO2 NPs are common ingredients in sun protection products used to guard against UV exposure. However, the fate of NPs in the environment and the potential for toxic effects once absorbed into the body remain largely ...

One dimensional metal oxide nanostructures have attracted much attention owing to their fascinating functional properties. Among them, piezoelectricity and photocatalysts along with their related materials have stirred significant interests and widespread studies in recent years. In this work, we successfully transformed piezoelectric ZnO into photocatalytic TiO2 and formed TiO2/ZnO axial heter...

We report a novel synthesis of Ti5Si3 nanoparticles (NPs) via the magnesio-reduction of TiO2 NPs and SiO2 in eutectic LiCl-KCl molten salts at 700 °C. The Ti5Si3 particle size (∼25 nm) is confined to the nanoscale due to the partial dissolution of Mg and silica in the molten salts and a subsequent heterogeneous reduction on the surface of the TiO2 NPs.

Titanium dioxide (TiO2) is a key component of diverse optical and electronic applications that exploit its exceptional material properties. In particular, the use of TiO2 in its single-crystalline phase can offer substantial advantages over its amorphous and polycrystalline phases for existing and yet-to-be-developed applications. However, the implementation of single-crystal TiO2 has been hamp...

Scanning transmission electron microscopy and density functional theory are used to characterize atomic structures of nanoscale heterointerfaces between gold nanoparticles and a TiO2 (110) surface. It is found that when the gold nanoparticle size is smaller than a few nanometers, gold atoms preferentially attach to specific sites on the TiO2 surface and thus form an epitaxial and coherent heter...
