Carbon Energy, EarlyView.A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...
