Diffusion of strontium implanted in glassy carbon [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021
Glassy carbon has properties making it attractive as a containment material for radioactive waste. In this study, the diffusivity of the radiological important fission product, strontium, is measured. Two hundred kiloelectronvolt strontium ions were implanted at room temperature.

Microbial formation of crystalline strontium carbonate [PDF]

open access: yesFEMS Microbiology Letters, 1994
Pseudomonas fluorescens appeared to grow in a mineral medium containing strontium (5 mM) complexed to citrate, the sole source of carbon, without any evident inhibition in cellular yield. Atomic absorption studies showed that the divalent metal was excluded from the cytoplasmic component and was initially found in the supernatant fluid in soluble form ...
