Cellulose nanofibers prepared by TEMPO-mediated oxidation of native cellulose
TLDR
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 celluloses/water slurries.About:

Wood nanocelluloses: fundamentals and applications as new bio-based nanomaterials
TL;DR: Nanocelluloses, which include nanofibrillated celluloses (NFCs) and cellulose nanocrystals (CNCs), are promising new bio-based nanomaterials, prepared from wood and other plant celluloses by mechanical shearing in water with or without pretreatments as discussed by the authors.

Thermal stabilization of TEMPO-oxidized cellulose
TL;DR: In this article, a partially C6-carboxylated cellulose with carboxylate content of 1.68mmol/g was prepared by 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation of a softwood bleached kraft pulp.

Darrell H. Reneker,Iksoo Chun +1 more
TL;DR: More than 20 polymers, including polyethylene oxide, nylon, polyimide, DNA, polyaramid, and polyaniline, have been electrospun in this paper.
Journal ArticleDOI
Homogeneous suspensions of individualized microfibrils from TEMPO-catalyzed oxidation of native cellulose.
TL;DR: Never-dried native celluloses (bleached sulfite wood pulp, cotton, tunicin, and bacterial cellulose) were disintegrated into individual microfibrils after oxidation mediated by the 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical followed by a homogenizing mechanical treatment.
Journal ArticleDOI
Effect of reaction conditions on the properties and behavior of wood cellulose nanocrystal suspensions.
TL;DR: Increased acid-to-pulp ratio reduced the dimensions of the nanocrystals thus produced and the critical concentration was increased and the biphasic range became narrower; a suspension made from a bleached kraft eucalyptus pulp gave very similar properties to the softwood nanocrystal suspension when prepared under similar hydrolysis conditions.

Polymer nanofibers assembled by electrospinning
TL;DR: Electrospinning is a process by which polymer nanofibers (with diameter lower than 100 nm and lengths up to kilometres) can be produced using an electrostatically driven jet of polymer solution (or polymer melt) as mentioned in this paper.
