A generalized kinetic model for the formation and growth of single-walled metal oxide nanotubes

▸ A detailed population-balance model of single-walled nanotube growth is developed. ▸ The model is validated and parametrized by detailed statistical TEM measurements. ▸ The model captures all the mechanistic features observed in growth experiments. ▸ Both precursor addition and oriented nanotube attachment are important mechanisms. ▸ The model successfully predicts the results of changing the growth conditions.
