Valorization of palm oil empty fruit bunch biomass into sulfonated lignin nanoparticles as sustainable retarders for high-temperature oilwell cement systems

The growing need for sustainable materials in the energy and infrastructure sectors has intensified efforts to valorize lignocellulosic biomass into high-value functional additives. This study addresses the limited availability of eco-efficient cement retarders capable of performing under ultra-high...
