ok, I can't add comments where I want, so I write it down here :
1.) there is a broken link in the toc for 4.1.1 with "peak water" ? I did not manage to fix it ...
2.) all the orcid id and award_url have the "} included. That means they link to a broken link. Is this wanted or should we make there a blank space ; e.g. it is like that "award_URL": "https://www.bmbf.de"} and we could change it to "award_URL": "https://www.bmbf.de "} or are these cells not visible in that way in the published notebook?
