Controllable Synthesis of Modified Porous Anatase TiO₂ with High Photocatalytic Activity.

In this study, we added ZrO₂ and Y₂O₃ to stabilize the anatase TiO₂ phase at higher temperatures. Composite mesoporous TiO₂/ZrO₂/Y₂O₃ (TZY) oxides were prepared by a sol-gel method, and triblockcopolymer P123 and PEG was used as templates. The properties of the synthesized materials were characterized using X-Ray diffraction (XRD), Raman scattering, N₂ adsorption/desorption, and UV-Visible spectrophotometry (UV-Vis) methods et al.

[Effects of arsenic on nerve growth factor and nerve growth related mRNA expression in F1 hippocampal].

Objective: To observe the mRNA expression of nerve growth factor (NGF) and nerve growth related proteins-43 (GAP-43) on hippocampus of F1 generation female rats after the pregnancy and lactation rats exposure to arsenic sodium.

Methods: 12 of pregnancy rats were exposed to arsenic (0, 10, 50, 100 mg/L, respectively in drinking water) from the 6 gestation day till F1 pups being 21 days old. Select females for expriments.
