Rojas Michea, Carolina; Morel, Mauricio; Gracia, Francisco; Morell, Gerardo; Mosquera, Edgar (Elsevier, 2020)Cu-doped ZnO nanocrystals (with 0, 0.5, 1.0, 1.5, and 2.0 at.% Cu) have been successfully synthesized by a solgel method. The influence of Cu content on the properties of ZnO nanoparticles have been studied by ...

Influence of micro and nanoparticles of zirconium oxides on the dielectric properties of CaCu3Ti4O12 Espinoza González, Rodrigo; Mosquera, Edgar (Elsevier, 2017)This work presents the results of Zr oxide doping of a CaCu3Ti4O12 (CCTO) ceramic prepared by a solid-state reaction. Different stoichiometries (ZrO and ZrO2) and grain sizes (micro- and nanoparticles) were added as dopants ...

Orive, Joseba; Sivasamy, Ramesh; Fernández de Luis, Roberto; Mosquera, Edgar; Arriortua, María I. (Royal Soc Chemistry, 2018)A novel 2D metal oxalatophosphite, K2Mn2II(H2O)(2)C2O4(HPO3)(2) (KMnCP), was hydrothermally synthesized and characterized. The hexagonal morphology and crystal growth faces of KMnCP were predicted by the Bravais-Friedel- ...
