Regioselectively Oxidized Cellulose Ethers
Macromolecular Symposia, 2009AbstractSummary: 3‐Mono‐O‐(2‐methoxyethyl) cellulose (MEC) was selectively oxidized with 2,2,6,6‐tetramethyl‐1‐piperidinyloxy radical (TEMPO)/NaBr/ NaOCl. According to 1D and 2D NMR measurements, the primary hydroxyl group was completely oxidized without affecting the secondary one at position 2.

Oxidized Regenerated Cellulose Imitating Pelvic Abscess
Obstetrics & Gynecology, 2013Oxidized regenerated cellulose is a topical hemostatic agent that is used commonly in abdominal and pelvic surgery. Although oxidized regenerated cellulose mimicking an abscess has been reported after different operations, little is known about its side effects after gynecologic surgery.Two women were diagnosed with postoperative abscess and intra ...

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.

TEMPO-Mediated Oxidation of Cellulose III
Biomacromolecules, 2003Various cellulose samples converted into cellulose III by two different ammonia treatments, either liquid or gaseous, were reacted with catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO), sodium hypochlorite, and sodium bromide in water.

Oxidized Regenerated Cellulose for Hepatic Hemostasis
Archives of Surgery, 1963Introduction Oxidized regenerated cellulose is a relatively recent addition to the surgeon's armamentarium for hemostasis. Its hemostatic and absorbable qualities have been attested to by several authors in recent articles. 1-5 There have also been several articles describing its chemical nature, the mechanism of solubility in human tissues, and ...

Oxidation of macroradicals in celluloses and cellulose nitrate
Polymer Science U.S.S.R., 1990The ESR method has been used to study the reaction of oxidation of macroradicals in UV- and γ-irradiated cotton cellulose and cellulose nitrate with oxygen dissolved in these polymers. The degree of oxidation of the alkyl radicals in the polymers studied did not exceed 30% which is apparently linked with the diffusion difficulties of access of oxygen ...

Journal of Hazardous Materials, 2020
High performance biopolymer films are of great interest as effective alternatives to non-biodegradable and petroleum-based polymer films. However, most natural biopolymer films possess weak mechanical and poor gas barrier properties, limiting their applicability.

Biodegradation studies on periodate oxidized cellulose
Biomaterials, 1982Abstract Sodium periodate oxidized cellulose was found to degrade into small molecules when implanted subcutaneously in rats. Thus the potentiality of using oxidized cellulose as a biodegradable drug carrier is envisaged.

Irradiation of Cellulosic Pulps: Understanding Its Impact on Cellulose Oxidation
Biomacromolecules, 2012Different 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.
