Reviewer 1 Report

Comments and Suggestions for Authors

The article is very interesting, the introduction chapter is well written, and the methodology and the description of the results are understandable in principle, but I still feel unsatisfied about the explanation of the holes, apparently a lot of space was devoted to them - but I cannot form an opinion about them after reading the article. I understand the search for a way to improve properties, but how does it quite work? 

With the automatic numbering of literature references, there were errors displayed in the text.

Abstract is a bit too general, please devote more to your successes in your work.

What do you mean by arguments in table 1, completely misses the word.

The conclusions are perhaps a little too elaborate.

kind regards
