In this work. few-layer graphene materials were produced from Fe-lignin nanocomposites through a molecular cracking and welding (MCW) method. MCW process is a low-cost. scalable technique to fabricate few-layer graphene materials. https://www.bekindtopets.com/flash-grab-DuramaxTuner-DT8170010101080-Switch-on-the-Fly-Tune-incl-EFI-Live-Spade-cDuramax-LWN-flash-save/
