The field of nanostructured materials is in a rapid development in many disciplines, e.g. condensed matter physics and materials science. Several techniques have been applied for sample preparation, for example, gas condensation, sputtering, electrodeposition, and thermochemical methods. One of the methods that has received significant attention is mechanical attrition:the high-energy ball milling of single or multicomponent powders. In this year, we successfully synthesised nanometer-sized ZnFe2O4, NiFe2O4, CuFe2O4, nanoalloying in Fe2O3-SnO2, Fe-Cu and mechanochemical reactions in Fe-S.
