referenceKumar et al. (2024) describe the functionalization of cellulose nanocrystals with a potent antimalarial compound, including synthesis, characterization, and biological studies, in the Int. J. Biol. Macromol.
referenceBarana et al. (2016) published 'Biorefinery Process for the Simultaneous Recovery of Lignin, Hemicelluloses, Cellulose Nanocrystals and Silica from Rice Husk and Arundo Donax' in Industrial Crops and Products, describing a method to extract multiple components from agricultural residues.

procedureZhu et al. synthesized novel organic-inorganic materials for acoustic absorption by modifying cellulose nanocrystals (CNC) with methyltrimethoxysilane (MTMS) to create Si–CNC, then mixing it with red mud and the cross-linking agent Hexamethylene diisocyanate (HDI).
referenceS. Raghunath, M. Hoque, and E. J. Foster examined the roles of cellulose nanocrystals in fiber cement, specifically regarding rheology, hydration kinetics, and mechanical properties, in a 2023 study.
referenceSaralegi et al. studied the shape-memory properties of segmented thermoplastic polyurethanes incorporated with cellulose nanocrystals (CNC). The study utilized castor oil as a source for polyurethanes and corn cob as a source for CNC, which were covalently bound. Thermo-mechanical data confirmed nearly 100% shape recovery in the second cycle, with CNC increasing hard phase crystallinity and generating more network points.
referenceCellulose nanocrystals can be applied in 3D printed alkali-activated cementitious composites, as demonstrated by A. A. Fahim, N. Admassu, G. Dailey, and M. Khanzadeh Moradllo in a 2024 study.
referenceG. Zhu et al. created aerogels based on the valorization of organic and inorganic waste, specifically cellulose nanocrystals and red mud, which exhibit high-adsorption, self-extinguishing, thermal, and acoustic-resistance properties.
referenceSaralegi et al. investigated the role of cellulose nanocrystals in improving the shape-memory properties of castor oil-based segmented thermoplastic polyurethanes in 2014.
