Summary: Material scientists and engineers are engaged in developing a variety of recipes for producing functional materials,
comprised of particles with uniform morphological features. There is a need to develop conditions for the synthesis
of a number of inorganic and ceramic systems in pure and in core-shell configurations comprising of monodispersed
particles. They are of great relevance and immense technological importance. For example, zinc oxide (ZnO) particles
of reasonable uniformity employed to fabricate planar chemical sensors for the detection of ethanol, ammonia, and
automobile exhaust gases have shown that the sensitivity and response/recovery time of these sensors were better
than those made with commercial ZnO powder. One of the objectives of this collaborative investigation was to
understand the role of starting precursors, experimental conditions and shape-modifying additives that control and
impart exotic morphologies. Another objective is to optimize the process parameters for higher yield. The technique
will be extended to double and higher oxides of relevance and direct impact in the renewable energy arena.
