The oxygen reduction reaction (ORR) is one of the most important electrochemical reactions
in energy conversion and storage technologies, such as fuel cells and metal–air batteries …

Dye-sensitized solar cells (DSSC) are known as a hot subject in the photovoltaic (PV) field.
Several materials are used to fabricate a DSSC, including titanium dioxide/metal oxide …

As an important strategic resource, rare earths (REs) constitute 17 elements in the periodic
table, namely 15 lanthanides (Ln)(La–Lu, atomic numbers from 57 to 71), scandium (Sc …

Abstract CaMnO 3− δ with δ= 0, 0.06, and 0.11 was prepared by the Pechini citrate gel
process at 1100 C. Oxygen defects were created by quenching the sample from high …

A series of eight AMnO 3 perovskites in which the A-cation sites are occupied by a
distribution of 70% trivalent lanthanide and 30% divalent Ca, Sr, or Ba ions has been …

The structural, magnetic and electronic properties of the polycrystalline La1− xAgxMnO3 are
systematically investigated as a function of Ag-doping level. The result of the Rietveld …

The influence of A-site cation disorder of monovalent alkali ions on structural and magneto-
transport properties of colossal magnetoresistive (CMR) materials has been reported. All the …

The use of a sol–gel synthetic method allows the preparation, at temperatures as low as
873K, of single-phase perovskites in the potassium-doped lanthanide manganites La1 …

We have measured the (cubic-lattice-approximation) elastic moduli of optical melt-zone-
grown single-crystal La 0.83 Sr 0.17 MnO 3 using resonant ultrasound spectroscopy. We …

The structural, magnetic, and electronic properties of the polycrystalline La 1− x Na x MnO 3
(x= 0.10, 0.15, 0.20, and 0.30) are investigated. The result of the Rietveld refinement of x-ray …
