Any chance you have a source or reference to the people who disagreed? Not trying to snark, I’m genuinely interested in seeing the counter arguments. Thanks

  There are a few ways that it might not be "graphene". First, it probably isn't monolayer, but rather variable layer numbers, so practically speaking... it's probably graphite. Second, there is likely to be a lot of defects. So you don't get the full strength that you would find with single crystal exfoliated or epitaxially grown graphene. Still, I would imagine that a method like this could be useful, particularly if you were building a colony off-world. You don't need high-quality graphene for making composites for construction.

  It was on a graphene subreddit long ago (r/graphene or r/graphene_DIY .. not sure). The guy said something like "the methodology doesn't measure or assess the graphene type produced". I can't find who or what thread it was sorry. He didn't explain in details saying telling more would be intellectual property breach and that a lot of companies are searching for flash joule like techniques and if they were working they'd be in use yesterday.
