Chandra S., Sonkawade R.G., Kulriya P.K., Singh F., Avasthi D.K., Annapoorni S., Rana J.M.S., Ramola R.C., H N B GARHWAL University, IN

Polypyrrole thin films were prepared by electrochemical process and then these films were irradiated by Swift Heavy Ions and by gamma rays. The structural and optical properties of the Polypyrrole thin films were characterized by [...]

Glycerol Assisted Polymeric Precursor Route for the Synthesis of Nanocrystalline LiCoO2 Powders

Vivekanandhan S., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

LiCoO2 with Layer structure has been used as a cathode material in lithium batteries. Recently, it is found that the nanostructured LiCoO2 powders exhibit an enhanced electrochemical performance compared to their bulk. Physiochemical properties of [...]

Using Scanning Thermal Microscopy Techniques for In-Situ synthesis of Carbon Nanotubes at “room temperature conditions”

Mukkisa S., Banerjee D., Texas A&M University, US

Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of [...]

Characterisation of Native-State Soft Matter using ‘Multi-Mode’ Electron Microscopy

Stokes D.J., Baken E., Lich B.H., Hubert D.H.W., FEI Company, NL

Soft condensed matter and complex fluids are of increasing technological significance. It is therefore crucial that we extend the capabilities of conventional solid state imaging and analytical techniques to include the observation of materials such [...]
