RESEARCH
PROJECTS
Department of Science & Technology, New
Delhi (DST) funded a project on “Phonon Dynamics of Fullerenes and
Derivatives” from 1997-2001.
Under this project, we formulated a model that
interpreted bulk, structural and anharmonic
properties of fullerene solids.
This model was mainly based on
using rigid molecule interacting with another similar
molecules forming bulk fullerene materials as well as carbon nanotubes. This
model based on Van-der-Waals interactions was
used quite successfully to explain experimentally observed structures of
fullerenes and carbon nanotube bunches in
hexagonal forms.
ARMREB, DRDO organization funded a project on
“Model for high pressure in Energetic Materials and their Orientation Sensitivity
of Shock Initiation” from 2002-2005 .
Subsequent to this, another project funded by
DRDO on “Investigation of C60 and
carbon nanotubes
for their energy and shock absorbing properties”, was funded
in 2006 and ended in 2010. Under this project, we exploited shock pressure
absorbing capabilities of caged carbon materials. Apart from a theoretical investigation,
experimental study using coating of these materials on some substrates was
carried out and attenuation
of shock and energy as explored.
Currently a research project on graphene study has been awarded as Emeritus Scientist
which is effective from Dec., 2010. Under this a study on the newest carbon
based materials known as graphene is being done
to investigate the usefulness of these by substitutional
doping of carbon atoms with boron and nitrogen.
