Fe-based nanocrystalline materials exhibit, in a comparison with their crystalline form, some unique properties [1].
Recently we have reported structural and magnetic properties of (Fe80Nb6B14)1-xTbx bulk nanoctrystalline alloys that reveal hard magnetic properties and can be considered as highly coercive materials [5].
Apart from bulk materials, some applications require magnetic materials in a form of powder (or nanopowder).

Natural or synthetic polymeric supports are currently the most investigated materials for this purpose, owing to their flexible structures for more stable and efficient activity of immobilized enzymes.
In principle this difference in an oxidizing atmosphere might be due to inorganic materials.

Ceramic materials have high wear resistance, but very low antifriction capacity and low crack resistance.
Among the most promising ceramic materials for the operation of this friction unit are ceramic materials based on partially stabilized zirconium dioxide [1-3] characterized by a combination of good strength and tribological properties, as well as very high crack resistance.
Transition metal chalcogenides are considered solid self-lubricating materials suitable for operation in vacuum or under dry friction.

Material scientists are continuously looking for more active materials that can perform better in various conditions.
MOCVD is versatile technique to synthesize inorganic materials, which is actually extension of chemical vapour deposition (CVD) technique.
MOCVD technique has been adopted for the synthesis of inorganic nano materials in powder as well as in film form.
