Lignin from grape stalks: nanoparticle production through sonication. 1-1. Poster session presented at Dare2Change, Porto, Portugal.032aa78f-e83a-4437-a808-e1a0517e6300http://hdl.handle.net/10400.14/56605Lignin nanoparticles represent an emerging class of sustainable nanomaterials that can improve the valorisation of this abundant biopolymer through new applications [1]. This study focused on optimizing the production of lignin nanoparticles through sonication, using minimal amount of chemicals possible, while achieving small particle size and maintaining colloidal stability.engconference poster not in proceedings10.34632/032aa78f-e83a-4437-a808-e1a0517e6300
