Final storage of radioactive cesium by pollucite hydrothermal synthesis
The Fukushima nuclear accident has highlighted the importance of finding a better final storage method for radioactive cesium species. Cs is highly soluble in water, and can easily exchange with other alkali ions in zeolites or clays to form stable complexes. However, Cs(+) is released from Cs(+) complexes into water when surrounded by an excess of water. Pollucite may be the best final storage...
متن کاملThe Study of Pure and Mn Doped ZnO Nanocrystals for Gas-sensing Applications
ZnO and ZnO: Mn nanocrystals were synthesized via reverse micelle method. The structural properties of nanocrystals were investigated by XRD. The XRD results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. Resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...
متن کاملDoctor blade sol-gel deposition of a nano-composite copper-zinc oxide on borosilicate glass for advanced oxidative degradation of textille dye in water environment
Nano-composite copper-zinc oxide (NCCZO) was deposited on borosilicate glass using a novel sol-gel/doctor-blade technique. The photocatalyst was prepared from copper acetylacetonate, zinc acetylacetonate, monoethanolamine (MEA) and citric acid monohydrate at 75 oC, aged for 1 d and annealed at 650 oC. The properties of the NCCZO nano-composite were investigated by X-ray diffraction (XRD) and fi...

متن کاملFormulation and Evaluation of Nanocrystals of a Lipid Lowering Agent
Atorvastatin calcium, the lipid lowering agent, is taken as a model drug characterized by poor water solubility and bioavailability. In this study an attempt was made for preparation of nanocrystals using high pressure homogenization. A number of stabilizers were included as well as polymers at different concentrations, and the formulations were homogenized for ten cycles at a pressure of 1000 ...
