Author here. Three PhDs (Mathematics, Pisa; Quantum Chemistry, UCF; Materials Science, UTD — in progress), plus MS degrees from SJSU and CSU. The gmail is because this is independent work, not affiliated with any institution. v53 reflects thirteen years of development since the original 2013 publication (Graphene 1, 107–109). The barrier is verified at two independent levels of theory with a confirmed transition state. Happy to discuss the physics.
