High Klason lignin content (23 wt%) cellulose nanofibrils (LCNF) were successfully isolated from eucalyptus pulp through catalyzed chemical oxidation, followed by high-pressure homogenization. LCNFs had a diameter of ca. 13 nm according to AFM evaluation. Dense films were obtained through vacuum filtration (nanopaper) and subjected to different drying methods. When drying under heat and mild vacuum...
A facile, green and efficient microwave-assisted method was developed to oxidize cellulose hydrogel beads with neutral 2,2,6,6-tetramethylpiperidinyl-1-oxyl radical (TEMPO)-mediated system. Resulting cellulose beads were investigated by scanning electron microscopy, solid-state 13C-NMR spectra, and X-ray diffraction. The patterns of 13C-NMR spectra indicated that the oxidation occurred only at C6...
Carboxylated cellulose nanocrystals (CNCs) were decorated with CdSe/ZnS quantum dots (QDs) using a carbodiimide chemistry coupling approach. The one-step covalent modification was supported by nanoscale imaging, which showed QDs clustered on and around the CNCs after coupling. The QD–CNC hybrid nanoparticles remained colloidally stable in aqueous suspension and were fluorescent, exhibiting the broad...
