The authors present an experimental study of nano-scale defects in CL-20 under heating.
In the introduction, the authors foreground their work, focusing on the relationship between the presence of pores and sensitivity. It indeed the case, but I could not find any discussion on this issue. Therefore, I suggest include some comments on this and, probably, provide some discussion of how to avoid the increase of such defects, which increase sensitivity of energetic crystals, in particular CL-20.
