Synergistic Sequential Phosphoric Acid-Deep Eutectic Solvent Pretreatment-Based Biorefinery: Selective Fractionation of Sugarcane Bagasse and Isolation of Structurally Preserved Lignin

This study demonstrates a synergistic sequential pretreatment using dilute phosphoric acid followed by a choline chloride-lactic acid deep eutectic solvent to efficiently fractionate sugarcane bagasse into high-purity cellulose pulp and structurally preserved lignin with minimal degradation, offering a sustainable pathway for integrated biorefinery applications.

Decoupling Bulk Polarization and Interfacial Charge Processes in 2D Zn-HHTP MOF/PVDF Piezoelectric and Triboelectric Nanogenerators

This study demonstrates that incorporating 2D Zn–HHTP metal–organic frameworks into PVDF creates a tunable platform where piezoelectric and triboelectric nanogenerator performances are optimized at different filler concentrations (1 wt% and 3 wt%, respectively) because piezoelectric output relies on bulk polarization while triboelectric output depends on interfacial charge processes and surface properties.
