One precious tic of academic writing I implore you to avoid is "...in the literature".
"Novel contribution to the literature..."
"Unknown in the literature..."
"Fill a gap in the literature..."
You know what I mean.
The impression you create is that this is some silly self-referential game with only internal measures of importance.
Whether this is how you see science or not.....avoid creating this impression.
Talk about knowledge or understanding instead.
