K. Veera Brahmam, a scientist from Advanced Systems Laboratory, DRDO, Hyderabad, said that nano materials were stronger and lighter compared to others and that was precisely why they were extensively used in aircraft and space technologies.

Addressing a faculty development programme on applications of nano technology, jointly organised by the Departments of Mechanical Engineering and Chemistry of V.R. Siddhartha Engineering College, Mr. Brahmam spoke at length about the case studies of use of phenolic carbon nano tubes in the nose tip of hypersonic space vehicles, which can withstand temperatures up to 1,600 degree Centigrade.

He also elaborated on use of nano materials in development of DVDs, pen drives, LCD and LED televisions besides application of the technology in power and electronic sectors. He explained about application of the technology in areas of hydrogen storage in fuel cells, electrodes in manufacturing of batteries, nano solar cells , preparation of zinc oxide cosmetic powders and medical applications in orthopaedic and cancer treatment. K. Ramjee from Andhra University, Visakhapatnam, college Principal K. Mohana Rao, A. Ratnakar of Chemistry department, A.V. Ratna Prasad, Head of Mechanical Engineering Department, coordinators K. Srinivasa Rao and V. Balakrishna Murthy from the Mechanical Engineering department participated.
