"CHALLENGES IN SYNTHESIS OF NANOSTRUCTURES IN PLASMA VOLUME"

Founder and owner of the TheoretiK consulting

                We explored adsorption and migration behavior of a carbon
adatom on a negatively charged armchair SWCNT of finite length, finding
significant increase of the migration length. These finding could lead
to a profound increase of SWCNT growth rate in an arc plasma volume
aided by the carbon adatom flux on the external surface of SWCNT

                Using the quantum-classical molecular dynamics, we were
able to simulate synthesis of BN nanocages, nanococoons and fullerenes
as well as growth of SWBNNTs in volume of  electric arc plasma at normal
pressure. Contrary to the widely accepted root-growth  self-assembly
mechanism, no boron nanoparticles are required in order to serve as
nucleation point for BNNTs and BN nanocages.
