Raspberry‐Like Microspheres of Core–Shell Cr 2 O 3 @TiO 2 Nanoparticles for CO 2 Photoreduction

ZnO, TiO(2), SiO(2,) and Al(2)O(3) nanoparticles-induced toxic effects on human fetal lung fibroblasts.

OBJECTIVE This study aims to investigate and compare the toxic effects of four types of metal oxide (ZnO, TiO(2), SiO(2,) and Al(2)O(3)) nanoparticles with similar primary size (∼20 nm) on human fetal lung fibroblasts (HFL1) in vitro. METHODS The HFL1 cells were exposed to the nanoparticles, and toxic effects were analyzed by using MTT assay, cellular morphology observation and Hoechst 33 258...

Colloquium Study of Nd 3 , Pd 2 , Pt 4 , and Fe 3 dopant effect on photoreactivity of TiO 2 nanoparticles

The metallorganic chemical vapor deposition method was successfully used to synthesize pure TiO2 and Nd3 -, Pd2 -, Pt4 -, and Fe3 -doped TiO2 nanoparticles. Polycrystalline TiO2 structure was verified with x-ray diffraction, which showed typical characteristic anatase reflections without any separate dopant-related peaks. Transmission electron microscopy observations confirmed the existence of ...

Collisional dissociation cross sections for O + O 2 , CO andN 2 , O 2 + O 2 , N + N 2 , andN 2 + N 2

Using laboratory data for the scattering of O by O2, CO and N2 pair potentials are constructed for O, C and N atoms. These potentials are then used to calculate collisional dissociation and energy transfer cross sections for O on O2, CO and N2; O2 on O2, N on N2, and N2 on N2. Since the energetic ions often neutralize in the atmosphere corona, such cross sections are relevant to plasma ion bomb...
