Jamshedpur: 26th November,
2008
National Metallurgical Laboratory, Jamshedpur will be organising the
VI International Conference on Mechanochemistry and Mechanical
Alloying during 1- 4 Dec, 2008. About 80 foreign delegates from 24
countries and 200 Indian delegates are expected to participate in
the Conference.
The INCOME series
of conferences initiated by International Mechanochemistry
Association [an associate member of International Union of Pure and
Applied Chemists (IUPAC)] has served as a common platform to bring
together all stakeholders from academia, Research and Development
organisations, and industry to foster the growth of the
discipline.The first international conference on ‘Mechanochemistry
and Mechanical Alloying (INCOME1992)’ was held in Koásice (Slovakia)
in 1992. This was followed by INCOME1997 in Novosibirsk (Russia),
INCOME2000 in Prague (Czech Republic); INCOME2003, in Braunschweig
(Germany), and INCOME2006 again in Novosibirsk. This is the first
time that a conference of INCOME repute is going to be held in
India, and in Jamshedpur.
Dr. T. Ramasami,
Secretary, Department of Science & Technology, Govt. of India will
be the chief guest. Prof. M. Senna, President , International
Mechanochemistry Association will give the conference lecture. In
addition to presentation of technical papers, scientific posters
will be displayed. An
exhibition has also been also organized where state of the art
milling devices and characterization equipments will be displayed.
Mechanochemistry
and mechanical activation have moved a long way and have evolved as
frontier areas of research and applications, during the last two to
three decades. Notable developments have taken place in terms of
scientific understanding and applications in diverse fields,
encompassing all facets of metallurgy including metal extraction,
alloying, composites; traditional and advanced ceramics processing;
paints, pigments and dyes; catalysis, pharmaceuticals, agriculture,
utilization of wastes, energy and environment, and many more.
Simultaneous developments have taken place in terms of
characterization techniques of activated solids; quantification and
control of activation processes; and mechanical activation devices
for specific needs, etc. The developments in the field of
mechanochemistry are unfolding at a rapid rate in terms of basic
science, range of applications, and their impact. While significant
advances are taking place in each of the application areas, e.g.
smart mechanochemistry, pharmaceuticals, etc., and call for periodic
review, the need for cross fertilization of concepts and ideas is
increasingly becoming apparent. The four day deliverables will
contain all facets of Mechanochemistry including basic science,
application to various areas, newer developments and devices, and
industrial applications.

Jamshedpur, 4th
December 2008
The fourth day of the VIth
International Conference On Mechanochemistry and Mechanical Alloying
(INCOME 2008) included sessions in Mechanical Alloying and Advanced
Materials, and Advance Ceramics Science and Technology. The sessions
were preceded by the Plenary Session Special Lectures. A total
number of 11 papers were presented today. The sessions of today were
preceded by three Plenary Lectures: “Glass formation” presented by,
Prof.P.Ramachandra Rao, “Local structure and size- dependent
properties of nanooxides prepared by mechanochemical routes“
presented by Dr. V. Šepelák, Braunschweig University
of Technology, Germany , and ” Specifics of mechanically driven
atomic distributions in interstitial alloys” presented by, Dr. J.
Foct, Université de Lille. Some of the important papers
presented in today’s sessions are as follows:
Dr. S. Srikanth, National
Metallurgical Laboratory Madras Centre, Chennai presented “Where
does the energy go in high energy milling?. He highlighted that for
understanding the magnitude and timescales of the temperature rise
during the high energy milling process, a study was undertaken using
low melting metals and alloys. The experimentally determined
crystallite size and strain correlated well with the values
estimated from line broadening analysis. Conversely, the
experimental melting point depression due to strain correlated well
with the theoretical calculations. Dr. P.C. Angelo, PSG College
of Technology, Coimbatore, presented “Hot isostatic
pressing of yttria dispersed 9Cr martensitic steel synthesized by
mechanical alloying”. He described the synthesis of ODS 9Cr
Martensitic steel by Mechanical Alloying of elemental metal
precursors. Nanocrystalline yttria used as the dispersoid was
synthesized via an efficient and economic Sol-Gel method. Dr. S.
Tikhov, Boreskov Institute of Catalysis., presented “Design
of the composite porous cermets synthesized through mechanical
alloying of Cr-Al powder followed by hydrothermal treatment and
calcination” . He focused that the cermet monoliths have
sufficiently high mechanical strength (up to ~20 MPa) and porosity
(35-57 %) with large pores (1-10
mm)
to be used as catalyst and membrane supports. The evolution of
microstructure with the Cr-Al powder alloying time had been
discussed. Dr. P.Brahma,
Gurudas College,Kolkata,
presented “Novel transport properties of nanostructured ferric
oxide“ He highlighted that the resistivity variation of the
unmilled sample can be ascribed to typical band conduction. The
resistivity decreases substantially with the progress of ball
milling. A decrease of about two orders of magnitude of resistivity
was observed for the specimen ball milled for 10h.It is clearly
observed that the resistivity variation of the Two activated
processes were observed with activation energies of
~0.06
and
~0.7eV,
respectively. Large and small particle sizes are responsible for the
two activation energies.
Dr. P. P. Chattopadhyay, Bengal
Engineering and Science University, Shibpur,
presented “Blue-violate photoluminescence from colloidal suspension
of nanocrystalline silicon-silicon oxide matrix prepared by ball
milling” He said that the intense violet-blue emission from nc-Si in
Si-oxide matrix prepared by chemically induced oxidation of
mechanically milled Si. Si powder was used as starting materials. He
also mentioned that there had been no previous report on blue PL
from nc-Si prepared by ball milling. The novel and inexpensive
synthesis route of nc-Si in oxide matrix, exhibiting blue-violet PL,
will open up a huge scope for potential applications. Dr. A.
Radhika
Devi,
Indian Institute of Technology, Chennai
presented
“Effect of surfactant addition on magnetic properties of Fe3O4
nanoparticles by ball milling” She said that, Magnetite nano
particles were synthesized in the presence of starch as surfactant
by ball milling for 30 hours in toluene medium. The amount of
surfactant addition was varied (8 wt %, 9 wt %,10 wt% ,11 wt % and
12 wt %) to study the variation of structural and magnetic
properties with surfactant content.
