Hollow nano-structures

Hollow nanostructures are of great interest as vehicles for drug delivery, as nano-reactors for gas phase reactions and for their unique optical, magnetic and electronic properties. In this research, we make use of Monte Carlo molecular dynamics simulation to investigate the formation of hollow nano-objects by tailored interdiffusion of coated nanospheres, see Figure 2. Since hollow nano-objects are, in principle, thermodynamically unstable, we are also making use of Monte Carlo and molecular dynamics methods to investigate the stability and shrinkage mechanisms of various hollow nano-objects by diffusion.
