Dsc of lignin
WebLignin nanoparticles (LNPs) exhibit excellent antioxidant capabilities and UV barrier compared to macromolecular lignin particles, making them suitable for gene delivery … WebAcid hydrolysis is a classic method used to assess the lignin and sugar contents of lignocellulosic biomass. The classic method involves two sequential hydrolyses. The first hydrolysis is performed at ambient temperature (30 ºC) for 60 min using 12 mol/L sulfuric acid (H 2 SO 4) (~72%) and a solid/liquid ratio of 100:1 mg/mL.
