Hi thanks for this submission and great job clearly articulating what you felt was exceptional about the article! Bonus points there :)
I agree that this is a very well written and properly cited article, and I do think it adds some value to Steemit because the author does have a talent for stating complicated concepts in an easy-to-understand manner. However the post mostly just summarizes the content of a single scientific paper and really does not add any original conclusions. Given this, it would be an extremely risky submission for Curie (if the author REP was in the right range) and would most likely not be approved. The headlines says "Breakthrough!!!" (with 3 exclamation points!!!)... but the post lacks a conclusion section explaining why it is important that they were able to achieve a stable plasma formation, or really any original thought by the post author at all. Why is this a breakthrough? Why is it important? What are the likely advances that will result from this? Why do we care that some scientists created a stable plasma formation without using an electromagnetic field? It is not enough to simply be a well written, well sourced and not plagiarized post (although these are all components of a successful Curie submission). Cheers - Carl
