Radiolabeling Dermacentor variabilis with Strontium-90 and Strontium-90 Plus Carbon-14 Mixtures12
Journal of Economic Entomology, 1970The feasibility of radiolabeling larval American dog ticks, Dermacentor variabilis (Say) with strontium-90 (90Sr) is demonstrated. The radioisotope was administered in inorganic form by inoculation of procreant females. Transovarial transfer to larval progeny resulted in sufficient radioactivity to permit easy detection of labeling in individual larvae.

Catalysis Today, 2019
Abstract The issue of obtaining heterostructures from strontium bismuthate and strontium carbonate is discussed. Effect of increase of photocatalytic activity of such heterostructures at the certain weight ratio of strontium carbonate is discovered. It is shown that increase of photocatalytic activity is correlating to opposite migrations of bismuth ...

Abstract Strontium carbonate with self-activated luminescence in the short-wave length region λ max = 490 nm is obtained by thermal decomposition of pure SrC 2 O 4 · H 2 O at 530°C. By means of EPR, CO 2 − radicals are found in the luminescent strontium carbonate, which are stabilized in anion sites and interstitial positions of the lattice.

Crystallization of carbonate hydroxyapatite in the presence of strontium ranelate
Crystallography Reports, 2015The influence of strontium ranelate on the crystallization of carbonate hydroxyapatite from a prototype of synovial fluid of humans has been investigated. The synthesis products are studied by IR Fourier spectroscopy, X-ray diffraction, and differential thermal analysis.

Acid Reactivity of Carbonated Apatites with Strontium and Fluoride Substitutions
Journal of Dental Research, 1983Carbonated apatites containing approximately 3.0 or 6.5% CO3 were precipitated in the presence of sodium, strontium, and/or fluoride at various concentrations. Almost all the available strontium and fluoride was incorporated into the crystals, whereas only a portion of the carbonate and sodium present was taken up. When incorporated together, Sr and F

Strontium, Magnesium, and Manganese in Fossil Foraminiferal Carbonates
The Journal of Geology, 1964The fraction greater than $62 \mu$ was separated from three deep sea cores, the calcium carbonate put into solution, and calcium, strontium, magnesium, and manganese determined in the calcium carbonate fraction. Strontium and magnesium were relatively constant in this carbonate fraction, but manganese showed a significant increase with depth in core.

A new high-pressure phase of strontium carbonate
Physics and Chemistry of Minerals, 2005High-pressure and high-temperature experiments conducted in a laser-heated diamond-anvil cell with a synchrotron X-ray diffraction method have revealed a phase transformation in the aragonite-type SrCO3 at pressures above 10 GPa. The new phase has an orthorhombic symmetry and was confirmed to remain stable to 32 GPa.

Kinetics of thermal decomposition of strontium zirconyl carbonate, Sr2Zr2O5CO3
Thermochimica Acta, 1985The kinetics of decomposition of the carbonate Sr2Zr2O5CO3, are greatly influenced by the thermal effects during its formation. (α−t) curves are found to be sigmoidal and they could be analysed based on power law equations followed by first-order decay.

The direct conversion of celestite to strontium carbonate in sodium carbonate aqueous media
Hydrometallurgy, 1996Abstract The leaching of celestite (SrSO4) particulate samples with Na2CO3 solutions was investigated. The effects of the variables: stirring speed; particle size; Na2CO3 and Na2SO4 concentrations; temperature; solution pH; and solid/liquid ratio were studied.
