Correction for 'Sequential separation of ultra-trace U, Th, Pb, and lanthanides using a simple automatic system' by Yutaka Miyamoto, et al., Analyst, 2015, DOI: 10.1039/c5an00027k.
We present a dynamical mean-field theory study of the valence transition (f;{14} --> f;{13}) in elemental, metallic Yb under pressure. Our calculations reproduce the observed valence transition as reflected in the volume dependence of the 4f occupation. The transition is advanced by heating, and suggests quasiparticle or Kondo-like structure in the spectra of the trivalent end state, consistent...
The group separation of trivalent actinides and lanthanides and the mutual separation of americium and curium are necessary for the transmutation of americium. We have proposed the separation system based on the chromatography using the tertiary pyridine-type resin. In this separation system, the complete separation method of the trivalent actinides and lanthanides are already established using...
Ca2+ transport across the membrane of vesicles derived from Azotobacter vinelandii was studied in the absence of respiration or functioning ATPase. Two facilitated diffusion systems were found. One, an electroneutral Ca2+/2H+ antiporter, responded to an artificially imposed deltapH, was heat-labile, and was insensitive to low concentrations of ruthenium red and lanthanides. The second, an elect...
Lanthanum (La) and the lanthanides (Ln) are the elements, numbered 57-71 of the periodic table. La and Ln occur more frequently than their name implies.
