Mn/Cr relative sensitivity factors for synthetic calcium carbonate measured with a NanoSIMS ion microprobe
secondary ion mass spectrometry Mn-Cr chronology relative sensitivity carbonate isotope
2017/8/9
Mn/Cr relative sensitivities for a synthetic calcite and a terrestrial olivine (San Carlos olivine) were measured using spot and rasterized modes with a NanoSIMS ion probe. Counting rates of 43Ca+, 52...

In the article, the results of examinations of changes in deformability of oxygen and sulphur inclusions in structural steel processed with calcium are discussed. The results obtained imply the positi...
Porous hydroxyapatite and biphasic calcium phosphate ceramics promote ectopic osteoblast differentiation from mesenchymal stem cells
calcium phosphate ceramics porous structure osteogenesis
2010/1/19
Because calcium phosphate (Ca–P) ceramics have been used as bone substitutes, it is necessary to investigate what effects the ceramics have on osteoblast maturation. We prepared three types of Ca–P ce...
