Bivalent europium selectively reduces mendelevium to a monovalent state, but does not reduce fermium, einsteinium or californium, thus mendelevium can be separated from such mixtures: Mendelevium Production Method (1983).
Nanopigments and inks including compounds of long lists of metals, which include mendelevium, have been suggested:
- Inorganic Colors And Related Nanotechnology (2008), and
- Ink Nanotechnology (2003).
