We have recently reported a method for obtaining about 30% of tetragonal β-FeSe in coexistence with hexagonal δ-FeSe and α-Fe phases by ball milling under an inert atmosphere, starting from FexSe powders with x = 1.00, 1.25 or 1.50, in which the u

In this work, hydrated nickel sulfates (NSHs) were spontaneously obtained by storing nanocrystalline nickel sulfide composites (NiS2–NiS) under ambient conditions over several months. The samples containing different proportions of NiS2–NiS nanop

In this work, the mill scale (MS) of hot rolling, a waste of steel processing, composed by a complex mixture of iron oxides, is transformed in a nanocrystalline powder containing only the hematite (α-Fe2O3) phase. For that, the MS was dry-milled usi
