In this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. An impression of grinding time on the structural and thermal properties of Sr-doped LaMnO3 system with La1-xSrxMnO3 (x=0.2) stoichiometric ratio was investigated. The nano crystallite LSM powder with cubic structure was prepared by varying the milling time of planetary monomill ...

In recent years, much research has been performed in the field of nanomaterials synthesis using mechanochemical process. In this research, TixAly/Al2O3 ceramic matrix nanocomposite was produced by the mechanochemical method. Aluminum and inexpensive titanium oxide powders were used as raw materials, and milling was performed under N2 atmosphere. The results showed that reduction of TiO2 by Al i...

Abstract: Nano- size alumina particles have been synthesized by mechanical activation of a dry powder mixture of AlCl3 and CaO. Mechanical milling of the above raw materials with the conditions adopted in this study resulted in the formation of a mixture consisting of crystalline CaO and amorphous aluminum chlorides phases. There was no sign of chemical reaction occurring during milling stag...

• Nanostructured cobalt ferrites' magnetic properties. “Janus effect” of starch coating on ferrite magnetization. Co-precipitation and hydrothermal methods/starch – increased Mechanochemical microemulsion decreased To investigate the behavior starch-coated ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted microemulsion, microwave-assis...

The relation between oxygen consumption and motility of Ciona spermatozoa has been measured by using pH stats to measure the acid production of spermatozoa swimming in dilute suspensions where their motility can be analyzed accurately, and calibrating the acid production by measuring it simultaneously with measurements of oxygen consumption, using more concentrated sperm suspensions. When the m...
