Airborne nano-TiO 2 particles: An innate or environmentally-induced toxicity?

Hierarchically multifunctional TiO(2) nano-thorn membrane for water purification.

A novel TiO(2) nano-thorn membrane was assembled for concurrent filtration and photocatalytic oxidization to remove pollutants in water. This membrane has hierarchical porous and multifunctional properties, which provide these advantages: (1) producing water with high quality; (2) increasing water flux; and (3) eliminating membrane fouling.

Orientation dependence in near-field scattering from TiO(2) particles.

This scattering of light by small particles embedded in a continuous transparent medium is influenced not only by the bulk optical properties of the particles and the medium but also by the size, shape, and spatial arrangement of the particles-that is, by the microstructure. If the particles are close together, as in agglomerated coatings or stereolithographic suspensions, interactions between ...

Requirements for innate immune pathways in environmentally induced autoimmunity

There is substantial evidence that environmental triggers in combination with genetic and stochastic factors play an important role in spontaneous autoimmune disease. Although the specific environmental agents and how they promote autoimmunity remain largely unknown, in part because of diverse etiologies, environmentally induced autoimmune models can provide insights into potential mechanisms. ...

Cluster-induced crystallization of nano-silicon particles

The possibility of producing from 20 nm to 100 nm sized silicon powders by plasma-induced reactions of silane including the formation of high-mass hydrogenated silicon anion clusters has been recently demonstrated. Careful HREM imaging showed circular contrast features, 1.5 to 2.5 nm in size, embedded in the amorphous particles which was attributed to the presence of medium range order in these...
