Vaginoplasty with oxidized cellulose in mayer–rokitansky–küster–hauser syndrome

Journal of Indian Association of Pediatric Surgeons, 2021
Mayer–Rokitansky–Küster–Hauser syndrome (MRKHS) is the major cause of vaginal agenesis. Vaginoplasty with oxidized cellulose has been used by gynecologists as a surgical option in vaginal agenesis; however, it is not very widespread among pediatric ...

Cellulose oxidation by Laccase-TEMPO treatments [PDF]

Carbohydrate Polymers, 2017
In this work, laccase-TEMPO (Lac-T) treatments were applied to bleached commercial dissolving pulp in order to introduce carbonyl and carboxyl groups, which were found to improve dry and wet strength-related properties.

TEMPO-Oxidized Cellulose Nanofibril Films Incorporating Graphene Oxide Nanofillers. [PDF]

Polymers (Basel), 2023
To design a new system of novel TEMPO-oxidized cellulose nanofibrils (TOCNs)/graphene oxide (GO) composite, 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation was utilized. For the better dispersion of GO into the matrix of nanofibrillated cellulose (NFC), a unique process combining high-intensity homogenization and ultrasonication

TEMPO-Oxidized Cellulose with High Degree of Oxidation. [PDF]

Polymers (Basel), 2017
In this paper, water-soluble 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose with a high degree of oxidation was prepared by a two-step process using bamboo dissolving pulp. The first step was to destroy the cellulose crystal I by NaOH/urea solution to obtain cellulose powder with decreased crystallinity.

A molecular scale analysis of TEMPO-oxidation of native cellulose molecules

Heliyon, 2020
The native cellulose, through TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation, can be converted into individual fibers. It has been observed that oxidized fibers disperse completely and individually in water.
