Commented on The origin of the surface barrier in nanoporous materials
Authors studied the origin of the surface barrier in nanoporous materials by experiments. Although I know how important the surface barrier is, authors didn't tell me why they want to study it at the case that many people have done much work. The major conclusion is the surface barrier is a surface diffusion process with high activation energy, which is not interesting or novel.

Commented on Remarks on adsorbent surface barrier to adsorbate mass transport
The author proposed a method, which may be used toely estimate the relative magnitude of the skin resistance. In fact, there are many experimental results to calculate this value. The author didn't compare with others. In the introduction section, author didn't explain why he/she intended to study this topic. In the conclusion section, author rewrote results from references and didn't tell readers any new things.
