   You should read the Yang et al., 2025 review article that the ID perps   
   cite in the scam article that you link to.   
      
   They go over the alternatives that are not subject to the slow   
   polymerization.  So the ID perp knew about the alternatives before they   
   wrote the bogus article, and only cite Yang et al. 2025 for the expected   
   time of polymerization in solution when Yang extensively reviews the   
   mineral catalyst option and notes the experimental sucesses.   
   Essentially they were quote mining, and Yang obviously was talking about   
   the options where the reaction is facilitated.

   Really, they cite an article noting that the time limit doesn't exist   
   because there are catalytic options.
