We have submitted our first interdisciplinary project. But it has been declined. This was submitted to "nature photonics. "
We are sure at these points
--->> This journal's scope contains directly our interets
--->> We are sure that we provided perspective paper and novel.
--->> this was scientific project : so in our cover letter we used this sentence " Author requires payment for his life expenses from universities who are willing to implement it"
But the output is this one
the paper falls outside the scope of the journal and aims and doesn't have sufficient relevance.
