Abstract:
Carbon nano structures such as fullerenes, nanotubes, and graphene are gaining considerable interest in the development of cleaner and higher performance next generation
energy devices. Improved methods of energy conservation, production, storage and
transmission using these nanostructures are expected to provide quick solutions for the existing
energy issues as well. The present talk will focus on the application of carbon nanotubes and
carbon nanostructures for energy production such as fuel cells, energy storage using
supercapacitors and energy transmission using quantum wires. Recent results on the enhanced
supercapacitor performance using carbon nanotubes and graphite oxide will be presented. The
limitations of carbon nanostructures regarding their synthesis, safety and possible exposure
issues will be discussed.
