U-xZr-yNb alloys with values of x varying from 32% to 50% (wt.%Zr) and y varying from 6% to 10% (wt.%Nb) were produced by the arc melting technique. The effect of the addiction of zirconium and niobium on the phase stabilization of γ-U, lattice para

The Zn1-x57FexO (0.0 x 0.10) and Zr1-xFexO2 (0.0 x 0.40) systems were synthesized, by freeze-drying and heat treatments, using as precursors of zinc and zirconium acetates (for lattice) and acetate enriched and natural iron (for doping). The heat tre
