Dear Colleagues
One of the major points that we have encountered in some cases is the rejection of our research work with non-professional comments. For example, today one of my paper is rejected in one journal. Two of three reviewers supported the paper and one of them rejected it with shallow comments. For example:
Reviewer comments: The title of the paper is tricky and I saw exergoenvironmnetal but I could not find the equation and the matrix. Can you elaborate more on the exergoenvironmental?
While the exergoenvironmental analysis is in the paper in one section and all of the related equations!!!!!!. It seems that the reviewer did not read a paper carefully and only skim read!!!! and rejected it.
I sent an email to the editor-in-chief but unfortunately, he did not consider my points about the non-professional comments of one of the reviewers.
I think all of us when one journal wants to review a paper, read the paper carefully, and then based on our knowledge put the comments. I always believe in except the special case that the paper has a very critical and conceptual mistake should not reject the paper.
We should give a time and permit the authors to correct the paper and promote it.
Dear colleagues
I was selected as a guest editor in the Energies Journal. The topic of this special issue is "Advances in Thermal Energy Storage Systems". If you have any papers in this regard, please let me know.

Error using refpropm (line 267)
