A strategic approach for preparation of oxide nanomaterials
K J Rao Krishnamurthy Mahesh Sundeep Kumar
A microwave assisted solvothermal method is described for rapid preparation of nano-oxides. This method is based on exploiting differential dielectric constants to induce preferred heating and decomposition of the oxide precursors in the presence of suitable capping agents. This strategic approach has been used to prepare nanopowders of MgO, NiO, ZnO, Al2O3, Fe2O3 and ZrO2.

Combustion synthesis of graphene and ultracapacitor performance
M Satya Kishore P Srimathi Sundeep Kumar Swarnagowri Addepalli Srinivasan Swaminathan Vinayak Tilak Robert Colborn
Graphene sheets are synthesized by a simple method starting from graphitic oxide as a precursor. Reaction of graphitic oxide at 250 °C with a combustion mixture of urea and ammonium nitrate results in the formation of thin graphene sheets. Graphene formation is characterized by XRD, TGA, XPS and TEM. Graphene materials synthesized by thismethod are investigated as an ultracapacitor material. Specific capacitance values of about 70 F/g are obtained at a current density of 100 mA/g by usingKOH as an electrolyte.
