Iranian researchers at
University of Tehran, synthesized nannocrystalline cupper particles by
mechanochemical reduction of Cuprite and investigated the kinetics of the
process for better understanding of the possible mechanisms.
"Cupper nanopowder is
prepared by mechanochemical reduction with graphite in a high-energy ball mill.
The results confirm the formation of Cupper nanopowder from Cu2O in a
single step process," Said S. Sheibani.
The average size of the
nanocrystaline Cupper was measured to be 27 nm after 30 hours of milling. The
nanopowder would have applications in microelectronics industry; to increase
thermal conductivity of fluids.
This research project
was carried out under the guidance of Dr. A. Ataie and Dr. S. Heshmati-Manesh,
both from School of Metallurgy and Materials Engineering in University of
Tehran.
The results was
published in the
International Journal of Modern Physics B, Vol. 22, Nos. 18 & 19 (2008)
2962-2969.
