Annals of Microbiology, 2012 The physiological and global transcriptomic response of the metal-resistant bacterium Cupriavidus metallidurans CH34 to stable non-radioactive strontium (Sr) was investigated. C. metallidurans CH34 was able to survive and proliferate in the presence of relatively high concentrations of SrCl2 (concentration of Sr needed to inactivate 90 % of the cells =

Incorporation of strontium in earthworm-secreted calcium carbonate granules produced in strontium-amended and strontium-bearing soil [PDF]
Geochimica et Cosmochimica Acta, 2013 This paper investigates the incorporation of Sr into biomineralized calcium carbonate granules secreted by the earthworm Lumbricus terrestris. Experiments were conducted using an agricultural soil amended with Sr(NO3)2 to give concentrations in the range 50 - 500 mg kg-1 Sr and a naturally Sr-rich, Celestine-bearing soil containing up to 11 000 mg kg-1

Oxidation of Carbon Monoxide on Strontium Ferrate
ECS Proceedings Volumes, 1995 The subject of conversion of natural gas to electric energy in Solid Oxide Fuel Cells (SOFCs) and formation of C{sub 2}-products from methane in electrochemical reactors, has received considerable attention recently. In order to reduce the problem of coke formation in SOFCs, methane is co-fed with water, forming CO and H{sub 2}.

Tuning the magnetic and electronic properties of strontium titanate by carbon doping [PDF]
Frontiers of Physics, 2021 The magnetic and electronic properties of strontium titanate with different carbon dopant configurations are explored using first-principles calculations with a generalized gradient approximation (GGA) and the GGA+U approach. Our results show that the structural stability, electronic properties and magnetic properties of C-doped SrTiO3 strongly depend ...
