"make graphene dissolvable by doping with nitrogen without: toxic chemicals/ harsh acids, >600 °C, significant waste... ball-milling grinds graphite with bio-derived amino acids, breaks/ reforms chemical bonds in solid state eliminating need for solvents, then paired with vitrimers... high electrical conductivity/ easier dispersion... 80% starting material converted to final product, no: long heating cycles (post-annealing)/ solvent recovery... electricity heals cracks... longer-lasting, repairable aerospace/ electronic components"
