Chandigarh, December 30
A talk on “Carbon nanotube materials in single and multi-walled formations” by Prof V.K. Jindal from the Physics Department, Panjab University, marked the conclusion of the five-day symposium on ‘Solid state physics’, organised here by the Department for Atomic Energy.
Prof Jindal showed how carbon nanotubes could easily slide, roll or rotate on a graphine sheet. From his experiments, it was concluded that these could be employed in the field of nano-electronics as extremely small-sized pistons and very smooth ball bearings.
Twelve oral presentations on different aspects of solid state physics were also made today. In a technical
session, chaired by Dr M Ramanadham from Bhabha Atomic Research Centre, Mumbai, various aspects of the symposium were discussed by senior scientists and suggestions were also provided by young researchers.
The maximum number of talks given during the symposium were on the subject of nano-materials, while the largest number of posters exhibited dealt with surfaces, interfaces and thin films.
Nano-structured materials could be thought of as materials of the size of one ten-billionth part of a meter. Such systems which consist of 10 to 1000 atoms would have unique properties and were catching worldwide attention as materials for future technology.
The award for the best thesis presented during the symposium went to Dr Arita Banerjee of the Indian Association for the Cultivation of Science, Kolkata. The thesis dealt with the
preparation, characterisation and measurement of properties of some magnetic materials.
