Korsunsky 3 and Svetlana A.Barseghyan1 1 Institute of General and Inorganic Chemistry, National Academy of Sciences, 2-tup, 10 Argutyan Street, 375051 Yerevan, Armenia 2 Department of Engineering Science, University of Oxford, Parks Road, Oxford OX1 3PJ, UK Keywords: Mechanical Alloying MA, Metallic Coating, Solid-State Chemistry, Tribology, Wear ABSTRACT A novel approach for metal surface modification and finishing is proposed and developed based on the in situ mechanochemical processing of metal oxides in reducing media.
It is our intention to use this technique in the future in order to clarify the coating structure and the relationship in which it stands with the mechanical properties.
The use of solid state chemistry opens opportunities for control over the composition and structure of the resulting coating, in the same way as mechanical alloying allows novel amorphous and nanocrystalline powders to be obtained.

PEG (polyethylene glycol) have been widely used in the synthesis of nanomaterials due to its special structure and performance.
Structure-directing Template method is commonly used in preparing size and morphology controllable nanoparticles.
More studies [8~10] have showed that in the preparation of nanomaterials, PEG played a structure-directing role by forming special micro structure under certain conditions or some interaction with some crystal plane of the products.

The compound might be used as a potential anti-tumor agent for the further structure modifications and development.
These useful pharmacological properties of benzofurans are attractive to chemists for constructing the different structural derivatives in synthetic and medicinal chemistry.
Nowadays, the microwave-assisted organic synthesis has been used to rapidly explore “chemistry space” and increase the diversity of the produced compounds [10].
Subsequent efforts to address the structure-activity relationship of this benzofuran derivatives and their anti-tumor mechanism would be reported in due course.
