  Several interesting phenomena are observed when materials are put under
pressure. The goal is to achieve modification and control over their mechanical
and electronic (conduction) properties. Within this spirit, we have recently
focused our attention into how carbon nanostructures respond to hydrostatic
pressure. We performed Monte Carlo simulations with the Tersoff potential of
various free-standing carbon nanostructures. These range from fullerenes,
onions and carbon spheres to nanotubes and nanodiamonds. Our simulations show
that the nanostructures undergo some notable structural modifications.
