Comparative Investigation of NaOH and KOH Treatments for Cellulose Purity and Polymorph Control in Pineapple Leaf Fibers: Crystallinity Changes and Electrochemical Impedance Signatures

Abstract A large percentage of pineapple leaves is now being disposed of as agricultural waste, but this biomass holds a lot of conversion potential to value-added products. This study systematically compares NaOH and KOH treatments for the selective extraction of cellulose micro...

Polylactic acid/cellulose nanocrystals/polyethylene glycol-based shape memory composite for a 4D printed thermoresponsive gripper system

This work introduces a novel thermo-responsive 4D printable gripper system via polylactic acid (PLA), cellulose nanocrystals (CNC), and polyethylene glycol (PEG)-based shape memory composite. PEG, serving as a biocompatible plasticizer, and CNC, acting as a biodegradable reinforc...
