Abstract The electrochemical and photochemical properties of graphene derivatives could be significantly improved by modifications in the chemical structure. Herein. reduced graphene oxide (RGO) was functionalized with l-arginine (l-Arg) by an amidation reaction between the support and amino acid. Deposition of a powerful ligand. https://www.roneverhart.com/Back-Roads-Apparel-Circle-Back-Roads-Apparel-3x3/
