I don't think something exists but basically it would be something like arxiv but on Nostr?

I just know about #nostrudel client that is optimal for long notes, and Wikifreedia made by Pablo.. I don't know if something can be already be done there or..

But maybe nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft will come up to something, I believe he also would like the idea of a solution to post scientific articles.. probably also nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z can have some idea, I remember is into medical stuff also.
