Zn-Fe flower-like nanoparticles growth by gas condensation
Lamsaf, H.; Lenzi, V.; Marques, L.; Rebouta, L.; Carvalho, S.; Ballesteros, Lina F.; Cerqueira, Miguel Ângelo Parente Ribeiro; Teixeira, J. A.Bimetallic nanoparticles have gained attention in the last decade due to their unusual characteristics compared to monometallic counterparts. However, production of such particles with controlled morphologies and composition need to be explored and the mechanisms understood. In this work, we demonstrate a fast and simple process to obtain flower-like Zn-Fe (Zinc-Iron) nanoparticles (NPs) using a hybrid system b...
Synthesis, Structural Studies, and Magnetic Properties of a New Mixed-Valence D...
Lamsaf, H.; Elghadraoui, E. H.; Lourenço, Rui Fausto; Oulmekki, A.; Costa, B. F. O.A new mixed-valence diphosphate, Zn2+5Fe3+2(P2O7)4, was synthesized from FeII5FeIII2(P2O7)4 via the “solid way” route, by substitution of FeII by ZnII. The obtained X-ray data confirmed the crystallization of the compound in the C2221 symmetry space group (orthorhombic). Magnetic measurements were performed showing that, at room temperature, the compound is paramagnetic and that the Néel temperature is 15.44(20...
