Oxidation and sulfonation of cellulosics

Cellulose, 2007
Bleached 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 ...

PERITONEAL REACTION TO OXIDIZED CELLULOSE

Archives of Surgery, 1948
RECENTLY 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.

Dual Functions of TEMPO-Oxidized Cellulose Nanofibers in Oil-in-Water Emulsions: a Pickering Emulsifier and a Unique Dispersion Stabilizer.

Langmuir, 2019
The emulsifying and dispersing mechanisms of oil-in-water emulsions stabilized by 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO)-oxidized cellulose nanofibers (CNFs) have been investigated.

The Oxidative Pretreatments of Cellulose for Cellulosic Superabsorbents

2023
Cellulosic 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

Oxidation Products of Cellulose. Salts of Oxidation Products of Cellulose

1995
The 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.

Irradiation of Cellulosic Pulps: Understanding Its Impact on Cellulose Oxidation

Biomacromolecules, 2012
Different pulp samples were irradiated by three energy sources: plasma, electron beaming, and γ radiation. The effect of increased exposure to irradiation was studied by multidetector gel permeation chromatography with fluorescence labeling of carbonyl groups to quantify changes of the cellulose.

Cadmium oxide/TEMPO-oxidized cellulose nanocomposites produced by pulsed laser ablation in liquid environment: Synthesis, characterization, and antimicrobial activity

, 2019
The TEMPO-oxidized cellulose nanofibers (TOCN) was prepared from bagasse pulp, followed by embedding with cadmium oxide nanostructure via pulsed infrared laser ablation of cadmium sheets immersed in TOCN solution in just one step.

Cellulose Nanofibers Prepared by TEMPO-Mediated Oxidation of Native Cellulose

Biomacromolecules, 2007
Never-dried and once-dried hardwood celluloses were oxidized by a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated system, and highly crystalline and individualized cellulose nanofibers, dispersed in water, were prepared by mechanical treatment of the oxidized cellulose/water slurries.

Adsorption of cellulose derivatives on inorganic oxides

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Adsorption of hydroxyethyl cellulose (HEC) and quaternary ammonium substituted HEC (QNHEC) on silica and titanium dioxide has been investigated as a function of pH and electrolyte (NaCl) concentration. Adsorbed amounts have been determined by means of reflectometry. Adsorption of HEC on SiO2 is constant up to pH=5. At higher pH the adsorption decreases,
