The email domain names of the first five out of seven co-authors are strange: @lund-univer.eu, @singapore-uni.com and @toronto-uni.com, all for authors affilated with institutions based in Kazakhstan or Russia.
These email domain names have been indentified as belonging to the tanu.pro publication agent, possibly paper mill. See Dr. Abalkina's overview document at https://docs.google.com/spreadsheets/d/1nkfI2bGmbBEiRV0P-XDojz9l0p7-6Uqh6GmiJLpc5Ck/edit#gid=0

There is a repeated panel in Figures 2 and 3 for specimens that are described differently (blue box highlights added). Also, the notion of "boiling" at 70 ºC seems problematic; it is, in any case, not consistent with the more plausible 100 ºC boiling process described earlier in the article.
