WebJan 1, 2005 · The alkaline extraction method is being investigated as a method to remove polonium (Po) from a lead-bismuth (Pb-Bi) cooled reactor. Tellurium (Te) was used as a surrogate for Po for these experiments to quantify the migration from Pb-Bi to molten alkaline (NaOH). Experiments provided direct evidence that molten NaOH can effectively … WebBismuth films with thicknesses between 6 and ∼30 nm were grown on Si (111) substrate by molecular beam epitaxy (MBE). Two main phases of bismuth — α-Bi and β-Bi — were identified from high-resolution X-ray diffraction (XRD) measurements. The crystal structure dependencies on the layer thicknesses of these films were analyzed. β-Bi layers …
