• Cellulose nanocrystals (CNCs) were extracted from brewery residues. CNCs used as building blocks for physically crosslinked hydrogel electrolytes. The electrolyte maintained excellent mechanical stability at various deformations. Animal bone was converted into ultra-high specific surface area porous carbon (PC) and electrode material. demonstrated symmetric flexible supercapacitor delivers su...

The anticoagulant activity of surfaces decorated with cellulose nanocrystals (CNCs) prepared via sulfuric acid hydrolysis, is explored. Such surfaces bear a high amount of negatively charged sulfate groups, which mimic the naturally occurring anticoagulant heparin in terms of charge density. It is demonstrated that CNC decorated surfaces significantly enhance the coagulation times of blood plas...

Synthesis of ZnO-Ag heterostructure nanoparticles was carried out by a precipitation method with cellulose nanocrystals (CNCs) as a stabilizer for antimicrobial and thermal studies. ZnO-Ag nanoparticles were obtained from various weight percentages of added AgNO₃ relative to Zn precursors for evaluating the best composition with enhanced functional properties. The ZnO-Ag/CNCs samples were chara...

The aim was to explore the utilization of tea leaf waste fibers (TLWF) as a source for the production of cellulose nanocrystals (CNC). TLWF was first treated with alkaline, followed by bleaching before being hydrolyzed with concentrated sulfuric acid. The materials attained after each step of chemical treatments were characterized and their chemical compositions were studied. The structure anal...

Excellent strength regenerated alginate composite fibers mixed with Poly (ethylene glycol) grafted cellulose nanocrystals (CNC-g-PEG) were prepared through a simple and scalable blending strategy. Firstly, high modulus (CNCs) fabricated based on waste cotton fabrics by the chemical treatment. (PEG) different molecular weight was onto CNC surface. The from CNC-g-PEG/sodium spinning dope wet spin...

This work is focused on the modification of interphase zone in short flax fibres / polypropylene (PP) composites by a bio-inspired called “nanostructuration” that uses adsorption biomass by-products, i.e. cellulose nanocrystals (CNC) and xyloglucan (XG), to create hierarchical fibres. The wettability interfacial adhesion study reveals strong decrease polar character CNC modified fibres, hence i...

Salix psammophila (SP) is an important sand plant, and could be utilized to develop high-value products. In this work, SP was used as raw material cellulose nanocrystals (CNC) were prepared by hydrolysis in 64 wt% sulfuric acid (H2SO4) solution, then, TEMPO/NaBr/NaClO system oxidize CNC obtain TEMPO-oxidation-cellulose (TOCNC). Fourier transform infrared analysis (FTIR) revealed that after oxid...
