Selectivity in biomineralization of barium and strontium.
The desmid green alga Closterium moniliferum belongs to a small number of organisms that form barite (BaSO(4)) or celestite (SrSO(4)) biominerals. The ability to sequester Sr in the presence of an excess of Ca is of considerable interest for the remediation of (90)Sr from the environment and nuclear waste. While most cells dynamically regulate the concentration of the second messenger Ca(2+) in...
متن کاملCrystal Chemistry of Immobilization of tetravalent Ce and Se in ceramic matrix of sodium zirconium phosphates
The safe and effective management of radioactive waste has been given utmost importance from the very inception of nuclear industry in India and it covers the entire range of activities from handling, treatment, conditioning, transport, storage and finally disposal. Radioactive waste is generated at various stages of the nuclear fuel cycle, which includes the mining and milling of uranium ore, ...

متن کاملPyroelectric properties of barium strontium titanate films: Effect of thermal stresses
A nonlinear thermodynamic model is used to investigate the influence of thermal stresses on the room temperature RT pyroelectric properties of 001 -textured polycrystalline barium strontium titanate BaxSr1−xTiO3, BST films with four different compositions on three integrated circuit-friendly substrates: Si, 0001 and 1̄1̄20 sapphire. It is found that the in-plane tensile thermal strain in BST incr...
متن کاملSBN60, strontium-barium niobate at 100 K
The title compound, Sr0.6Ba0.4Nb2O6 (strontium barium niobium oxide), belongs to the group of strontium-barium niobates with varying composition of Sr and Ba. Their general formula can be written as Sr x Ba1 - x Nb2O6. Below the Curie temperature, T c , these materials indicate ferroelectric properties. The Curie temperature for SBN60 is equal to 346±0.5 K so the structure is in the ferroelectr...
