The temperature dependence of the heat capacity nanostructured SmFeO 3 ceramics obtained by mechanical activation in range 120-800 K has been studied. It shown that excess mechanically activated is due to: displacements iron and samarium ions with a change angle between FeO6 oxygen octahedra. Keywords: multiferroics, capacity, ferrite, Schottky ceramics, activation.

abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...

Background: Heat shock may affect different aspects of oocyte maturation and its subsequent development to the blastocyst stage. A series of in vitro experiments was performed to determine whether physiologically heat shock (41°C) disrupts the progression of the ovine oocytes through meiosis, activation and blastocyst formation. Materials and Methods: The cumulus-oocyte complexes (COCs) were as...
