Magnetic refrigeration technology is a new, green, high-efficiency approach. It has attracted increasing attention from researchers and strong competitiveness over traditional methods. With the continuous development of social lives, magnetic must have important application prospects. This article briefly describes basic principles. The focus on introduction summary research perovskite manganit...

B1-xLaxFeO3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. XRD analysis confirmed the phase formation of the materials. Thermal characterization was done by DSC-TGA to confirm crystallization and thermal behavior for phase development. Morphological studies by FESEM showed the agglomerated nature of the ferrite...

After a general introduction into the Shockley theory of current voltage (J-V) characteristics of inorganic and organic semiconductor junctions of different bandwidth, we apply the Shockley theory-based, one diode model to a new type of perovskite junctions with polaronic charge carriers. In particular, we studied manganite-titanate p-n heterojunctions made of n-doped SrTi1- y Nb y O3, y = 0.00...

Rapid deactivation presently limits a wide spread use of high-temperature solid oxide cells (SOCs) as otherwise highly efficient chemical energy converters. With triggered by the ongoing conversion reactions, an atomic-scale understanding active triple-phase boundary between electrolyte, electrode, and gas phase is essential to increase cell performance. Here, multi-method approach used compris...
