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:

Solvent resistance of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) treated cellulose nanofiber film for flexible electronics
TL;DR: In this paper, the solvent resistance of 2,2,6,6-tetramethylpiperidine-1-oxyl treated CNF films was investigated in terms of solvent inertness and barrier properties against solvents.

Melt Processing of Cellulose Nanocrystal-Filled Composites: Toward Reinforcement and Foam Nucleation
Ting Zheng,Srikanth Pilla +1 more
TL;DR: In this paper, the low compatibility between the CNC-hydrophobic matrix and the cellulose nanocrystals (CNC) has been investigated for scalable nanocomposite manufacturing.

The vane method and kinetic modeling: shear rheology of nanofibrillated cellulose suspensions
TL;DR: In this article, the authors conduct rheological characterization of nanofibrillated cellulose (NFC) suspensions, a highly non-Newtonian complex fluid, at several concentrations, taking into account the prevalent problems of time scale issues, wall depletion and confinement effects.

Polyelectrolyte layer assembly of bacterial nanocellulose whiskers with plasmid DNA as biocompatible non-viral gene delivery system
TL;DR: By the use of BNC as sustainable raw material, in combination with optimized and controllable preparation conditions and surface modifications, BNC nanowhiskers modified by a polyelectrolyte layer approach could be used as renewable, “green” drug delivery system for bioactive substances such as nucleic acids.

Nanometre diameter fibres of polymer, produced by electrospinning
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.
