Journal ArticleDOI
Structural and morphological characterization of FeCo2O4 and CoFe2O4 spinels prepared by a coprecipitation method
Teresa Ferreira,Teresa Ferreira,João C. Waerenborgh,M.H. Mendonça,M.R. Nunes,Florinda M. Costa +5 more
TL;DR: In this article, a structural and morphological study of the FeCo 2 O 4 and CoFe2 O 4 spinels prepared by a low-temperature coprecipitation method has been undertaken.
Journal ArticleDOI
Synthesis, Chirality, and Magnetic Properties of Bimetallic Cyanide-Bridged Two-Dimensional Ferromagnets
Eugenio Coronado,Carlos J. Gómez-García,Alicia Nuez,Francisco M. Romero, ,† and,João C. Waerenborgh +4 more
TL;DR: In this paper, the chiral ligands trans-cyclohexane-1,2-diamine (trans-chxn) and trans-(1S,2S)-Chxn were used to obtain a two-dimensional two-layer ferromagnetic material of the general formula [Ni(trans-chi n)2]3[Fe(CN)6]2‚2H2O.
Journal ArticleDOI
Temperature and Composition Dependence of the Cation Distribution in Synthetic ZnFeyAl2-yO4 (0 ≤ y ≤ 1) Spinels
TL;DR: In this paper, the inversion degrees for ZnFe2O4 up to 1350 K were estimated by O'Neill and Navrotsky in the range 773-1223 K. The nonlinear enthalpy of disordering model was applied to several studies of simple spinel oxides.
Journal ArticleDOI

TL;DR: An isoreticular family of robust layered coordination polymers has been mechanically exfoliated to give functionalized crystalline magnetic monolayers to explore magnetism in the 2D limit and to fabricate mechanical resonators for selective gas sensing.
Journal ArticleDOI
Oxygen Ionic and Electronic Transport in Apatite-Type Solid Electrolytes
Vladislav V. Kharton,Aliaksandr L. Shaula,Mikhail V. Patrakeev,João C. Waerenborgh,D.P. Rojas,N. P. Vyshatko,Ekaterina V. Tsipis,Aleksey A. Yaremchenko,Fernando M.B. Marques +8 more
TL;DR: In this article, the ion transference numbers of apatite-type La 9.83 Si 4.5 Al 1.5, where oxygen interstitials are close neighbors of Si-site cations, were determined by faradaic efficiency measurements at 973-1223 K in air.
