TEMPO-oxidized cellulose nanofibers
Nanoscale, 2011Native wood celluloses can be converted to individual nanofibers 3-4 nm wide that are at least several microns in length, i.e. with aspect ratios>100, by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation and successive mild disintegration in water.

Periodate Oxidation of Crystalline Cellulose
Biomacromolecules, 2000Conversion of 1,2-dihydroxyl groups to dialdehyde by periodate oxidation is a useful method of derivatizing polysaccharides but has not been extensively utilized in derivatization of cellulose because of complicacy due to the crystalline nature of cellulose.

Electrocatalytic Oxidation of Cellulose at a Gold Electrode
ChemSusChem, 2014AbstractThe electrochemical properties of cellulose dissolved in NaOH solution at a Au surface were investigated by cyclic voltammetry, FTIR spectroscopy, the electrochemical quartz crystal microbalance technique, and electrochemical impedance spectroscopy. The reaction products were characterized by SEM, TEM, and FTIR and NMR spectroscopy. The results

Oxidation Products of Cellulose. Salts of Oxidation Products of Cellulose
1995The first spectra of a number of oxidized celluloses were obtained by Rowen, Hunt, and Plyler [164]. They used films of regenerated cellulose, oxidized by nitrogen dioxide or periodic acid. These authors erroneously attributed bands at 1640 and 1280 cm−1, in the spectrum of cellulose oxidized by nitrogen dioxide, to the carboxyl group.

The Oxidative Pretreatments of Cellulose for Cellulosic Superabsorbents
2023Cellulosic superabsorbents (SAP) are produced by using cellulose and cellulose derivative blends with different bindingmethods, generally. But cellulose in SAP leads decrease in water absorption and water bonding ability because of nonreactive character ofcellulose based on its chemical structure. The oxidative pretreatments of cellulose were attempted

PERITONEAL REACTION TO OXIDIZED CELLULOSE
Archives of Surgery, 1948RECENTLY there has been added to the armamentarium of the surgeon a gauzelike material which is completely absorbed in the tissues and serous cavities. This material is known as oxidized cellulose. Its physical and chemical properties have already been thoroughly described in the literature.

Oxidation and sulfonation of cellulosics
Cellulose, 2007Bleached hardwood (HW) kraft pulp and derived nanocellulosic structures were modified by a periodate oxidation followed by treatment with sodium bisulfite to yield the corresponding C2/3 sulfonates. The impact of this oxidative–reductive protocol on the chemical and physical properties of cellulose was evaluated by determining physical dimensions ...

Oxidation and aging of cellulose
Macromolecular Symposia, 1997AbstractOxidation of cellulose by chlorine, bromine, hydrogen peroxide and ozone and the functional groups formed are reviewed. The roles of the pH and of the nature of the oxidant in the formation of carboxy‐ and keto‐celluloses are discussed. The relationships between the functional groups, degradation and stability of the celluloses enable to ...
