La0.5Sm0.5FeO3: a new candidate for magneto-electric coupling at room temperature
(Springer, 2017-07)
Samarium substituted lanthanum orthoferrite La0:5Sm0:5FeO3 thin film has been prepared by soft chemical method. A single perovskite phase with orthorhombic crystallographic structure was attained. Magnetic and ferroelectric ...
Alkaline niobates ANbO3 (A = Li, Na, K) as heterogeneous catalysts for dipropyl sulfide oxidation
(Royal Society of Chemistry, 2016-10)
Alkaline ANbO3 (A = Li, Na, K) niobates with perovskite-type structure were prepared by a sol gel method, characterized by XRD, BET, TG/DTA, O2-TPD, DRS UV-Vis and FTIR and evaluated as heterogeneous catalysts for the ...
Magnetization and Specific Heat of La doped Sr2FeMoO6
(Elsevier Science, 2004-05)
We present high-temperature magnetization and low-temperature specific heat measurements performed on the electron doped double perovskite Sr 1.7La0.3FeMoO6. We have obtained the electronic contribution to Cp, γ=11.5(5)mJ/molK2. ...
Iron-based photocatalytic and photoelectrocatalytic nano-structures: Facts, perspectives, and expectations
(Elsevier Science, 2019-05-05)
The increasing demand for clean renewable energy needed for sustainable industrial progress and population growth is the driving force for the scientific community to achieve a continuous development in the field of ...
Magnetic held dependence of elastic modulus and resistance in La2/3Ca1/3MnO3
(Elsevier Science Sa, 2000-06)
We have measured the magnetic field dependence of the anelastic modulus and the electric resistance of a ceramic sample of the magnetoresistant perovskite La2/3Ca1/3MnO3 around the metal-insulator transition by the vibrating ...
Characterization of the high temperature properties of BaCe0.4Zr0.4Pr0.2O3−δperovskite as a potential material for PC-SOFCs
(Royal Society of Chemistry, 2021-08)
Compounds based on barium cerates and zirconates, Ba(Ce,Zr)O3−δ, are oxides able to transport protons through their crystal lattice by proton hopping between oxygen sites. This feature makes them potential candidates as ...
Nanostructured LnBaCo2O6-δ (Ln = Sm, Gd) with layered structure for intermediate temperature solid oxide fuel cell cathodes
(American Institute of Physics, 2017-04)
In this work, we present the combination of two characteristics that are beneficial for solid oxide fuel cell (SOFC) cathodic performance in one material. We developed and evaluated for the first time nanostructured layered ...
Elucidating the Methylammonium (MA) Conformation in MAPbBr3 Perovskite with Application in Solar Cells
(American Chemical Society, 2017-11)
Hybrid organic-inorganic perovskites, MAPbX3 (X = halogen), containing methylammonium (MA: CH3-NH3+) in the large voids conformed by the PbX6 octahedral network, are the active absorption materials in the new generation ...
Effects on the physical properties of cation substitution in the layered cobaltites Y (Ba1 - x Cax) Co2 O5.5
(Elsevier Science, 2007-09)
In this work we study the physical properties of the layered cobaltites YBaCo2 O5.5, focussing on the role of cationic disorder and size effects by a partial substitution of Ba by Ca. We have synthesized the polycrystalline ...
Electronic subband reconfiguration in a d0-perovskite induced by strain-driven structural transformations
(American Physical Society, 2012-11)
It is well known that transport in lightly n-doped SrTiO3 involves light and heavy electron bands. We have found that upon application of moderate quasi-isotropic pressures, the relative positions of these subbands are ...
