DESCRIPTION:Carbon is the fourth most abundant element after hydrogen\, he
 lium and oxygen in the universe. It is present in the sun\, stars\, comets
 \, and atmospheres of most planets. The unique chemical characteristics of
  carbon give it flexibility like no other atom in the periodic table. In t
 he pure form it is highly stable and requires high temperature to react wi
 th oxygen\nor other elements.\n\nThere are several allotropes of carbon an
 d the commonly known are diamond\, graphite and amorphous carbon (soot). F
 or hundreds of years carbon (coal\, gas and oil) has been used as the sour
 ce of energy for our civilization. Some of the other applications range fr
 om pencils\, indigestion tablets\, braking systems\, moderator/reflector i
 n nuclear reactors and plasma\nshielding tiles in fusion reactors.\n\nTher
 e is another allotropic form of carbon referred to as fullerenes (buckybal
 ls and carbon nanotubes). Carbon nanotubes are tubes with nanometre size d
 iameters and macroscopic size lengths made from just carbon atoms. They ar
 e particularly promising due to their lightweight and extraordinary electr
 ical\, thermal and mechanical properties that have captured the imaginatio
 n of researchers worldwide. However\, the key to the actual harvesting of 
 carbon nanotubes potential is in their controlled synthesis at the molecul
 ar level.\n\nIn this talk I will take you on the journey with carbon and f
 ocus on current and future remarkable potential it can offer.\n
