What were the topics and titles of your dissertation in the first two PhD? Were they related to this topic or totally different?

Edit: https://www.mathgenealogy.org/id.php?id=61429 It looks quite unrelated

First PhD: algebraic cryptanalysis (Pisa). Second PhD: exact solutions to the Schrödinger equation for few-body systems (UCF). Both unrelated to fluorographane — the connection emerged later.

This is their referenced 2013 paper on the subject:

Clearly they have been working on this for over a decade.

The journal (Graphene, ASP) ceased operations and the DOI infrastructure went dark. The paper itself is archived at ResearchGate: researchgate.net/publication/258423577. The content is independently verifiable.

I wanted to check the journal where it was published, there are good journals and bad journals.It's very strange that the doi is dead. I found this http://www.aspbs.com/graphene/contents_graphene2013.htm but it's also full of dead links.
