Carboxycellulose nanofibers were extracted from untreated jute using a simple nitro-oxidation method based on nitric acid/sodium nitrite. The characteristics of nitro-oxidized carboxycellulose nanofibers (NOCNF) with low crystallinity (35%), high carboxylate content (1.15 mmol/g) and high surface charge (− 70 mV) made them an excellent substrate for Pb(II) ion removal from water. For example, a low...
Carboxylated cellulose nanofibers (CNFs), having an average width of 7 nm and thickness of 1.5 nm, were produced by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation method. The fiber cross-sectional dimensions were determined using small-angle X-ray scattering (SAXS), transmission electron microscopy and atomic force microscopy techniques, where the rheological properties under...
Softwood is an abundant resource; however, currently its utilization for bioconversion to obtain platform sugars is limited. Pinus taeda trees which were genetically modified to either produce S lignin or to decrease lignin content were characterized with a suite of analytic techniques. Syringyl lignin was visualized in the secondary xylem of one genetic line with Mäule staining. Solid-state nuclear...
