Local Crystallinity in Twisted Cellulose Nanofibers [PDF]
ACS Nano, 2020 Cellulose is crystallized by plants and other organisms into fibrous nanocrystals. The mechanical properties of these nanofibers and the formation of helical superstructures with energy dissipating and adaptive optical properties depend on the ordering of polysaccharide chains within these nanocrystals, which is typically measured in bulk average ...

Plasmonic gold-cellulose nanofiber aerogels
Optics Express, 2020 Assembly of plasmonic nanomaterials into a low refractive index medium, such as an aerogel, holds a great promise for optical metamaterials, optical sensors, and photothermal energy converters. However, conventional plasmonic aerogels are opaque and optically isotropic composites, impeding them from being used as low-loss or polarization-dependent ...

ELECTROSPINNING OF ANTIBACTERIAL CELLULOSE ACETATE NANOFIBERS
Cellulose Chemistry and Technology, 2023 "Herein, it was aimed to achieve antibacterial cellulose acetate (CA) nanofiber production and characterization. Firstly, solution properties, such as viscosity, conductivity and surface tension, were determined. Secondly, CA/zinc oxide (ZnO) composite nanofibers were produced with optimum process parameters via the electrospinning method.
