Substantial differences for CNT structures

Under the scaling approach used in previous sections of this chapter, it must be recognized that the nano-scale is the only scale that contains more than two solid phases. In addition, it is the 

In an RHM the distribution of the possible structures could be uniform, where uniformity is a systematic parameter defined in the computational domain only. This observation allows both stochastic and deterministic conditions, as well as isotropic or anisotropic features to be considered. By reaching this point, the randomness of the final structure wRl be affected by initial conditions that introduce some deterministic touches to the final reconstructed heterogeneous material. Some approaches have proposed the use of electrodes with rather deterministic structures for electrochemical processes, for example, parallel and aligned CNTs, dots of controlled diameter catalysts supported on flat substrates, etc. 

For this example, the number of control volumes necessary to generate a computing domain of 300 nm scale in three dimensions (CV CNT) for an MWCNT structure of 50 nm diameter and 200 nm length. It was mentioned earlier that the diameter-to-length ratio for CTs could be around values of 200,000 or even larger. This gives an idea of the computing domain necessary for the reconstruction with various resolution levels.
