Tio 2 Sedimentation

TiO 2 nanoparticles enhance bioaccumulation and toxicity

The aim of this investigation was to illustrate the influence of TiO 2 NPs (5 and 15 nm) on the bioaccumulation and toxicity of cadmium (Cd), arsenate (As(III)), and nickel (Ni) in Caenorhabditis elegans (C. elegans) during the process of sedimentation in aquatic environment. Our data showed that HMs accelerated the aggregation of TiO 2 NPs.

Titanium dioxide nanoparticles (TiO 2 NPs) are among the most widely used NPs due to their interesting optical and catalytic properties. Most applications require their dispersion in fluid or solid matrixes. It is of first importance that NPs be and remain homogenously dispersed in the matrix to achieve optimal properties and stability.

Hierarchical structures of coated TiO 2 World Scientific

TiO 2 hierarchical structure composed of H 2 Ti 3 O 7 nanoribbons and TiO 2 anatase nanoparticles was synthesized via a two-step hydrothermal process, including the recrystallization of TiO 2 precursor into nanoribbons and the subsequent deposition of TiO 2 nanoparticles on nanoribbon surface. The coated nanoribbons exhibited a good photocatalytic activity to degrade Rhodamine B (RhB) with a
