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:

Nanocellulose as an inhibitor of water-in-crude oil emulsion formation
TL;DR: In this article, the use of aqueous suspensions of cellulose nanoparticles, both nanocrystals (CNC) and nanofibrils (CNF), to inhibit the formation of water/oil emulsions is reported.

Furan-modified natural rubber: A substrate for its reversible crosslinking and for clicking it onto nanocellulose
TL;DR: It is demonstrated here that natural rubber can be reversibly crosslinked via the Diels-Alder coupling of furan and maleimide moieties, thus generating a covalently crosslinked composite of these two renewable polymers.

Fabrication of double crosslinked chitosan/gelatin membranes with Na+ and pH dual-responsive controlled permeability.
TL;DR: A double crosslinked membrane based on chitosan/gelatin with controlled release properties was synthesized in aqueous system using potassium pyroantimonate and genipin as the ionic crosslinker and covalentCrosslinker, demonstrating the Na+-responsive and pH-responsive permeability of the films.

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.
