WitrynaImpurity atom MgO can dilute ions of similar size, as for instance Ni or Co forming NiO-MgO and CoO-MgO solid solutions with an infinite range of composition. The effect of progressively replacing Mg by Ni or similar cations (Co, Cu ) on the surface properties has been investigated both experimentally [111, 163,164] and theoretically [165,166]. … WitrynaThis document defines the stability data package for a new drug substance or drug product that is sufficient for a registration application within the ICH regions.
