Cellulose Acetate Fibers With Infiltrated ZnO Nanocrystals: Activation of Antibacterial Properties Against Acne vulgaris by Oxygen Plasma Treatment

Small, EarlyView.
We present biodegradable cellulose acetate fibers infiltrated with ZnO nanocrystals for Acne treatment. Fibers produced by centrifugal spinning were vapor‐phase infiltrated to contain uniform ZnO nanocrystals. Oxygen plasma treatment enhanced the fibers´ wettability.

In Situ Self‐Nanostructuring Enables Fast‐Recharging of an Aqueous‐Processed Organic Small Molecule Cathode

Small, EarlyView.
Self‐nanostructuring of redox‐active organic small molecules through in situ electrochemical postcrosslinking enabled an aqueous‐processed, stable, fast‐rechargeable organic electrode even with a high active content ratio and mass loading. ABSTRACT Redox‐active organic materials (ROMs) for batteries are emerging as sustainable alternatives to inorganic

Shear‐Induced Anisotropic Supramolecular Gel Noodles for Improved Cell Guidance in Polarized Tissue Engineering

Small, EarlyView.
A simple two‐stage extrusion aligns supramolecular fibrils into 1D gel noodles. The residual pressure in the viscous pre‐gel drives the formation of a thin filament that is locked by Ca2+ cross‐linker into a highly anisotropic segment. The aligned noodles show enhanced tensile strength and guide myoblast elongation along the fiber, mimicking aligned ...

Mechanically Enhanced, Antibacterial, and Double‐Network Hydrogel Flexible Sensors for Sleep Apnea Monitoring

Small, EarlyView.
This report describes the preparation of an antibacterial hydrogel sensor from a polyvinyl alcohol/silk fibroin double network, tannic acid‐coated liquid metal, and copper particles, with an ethanol post‐treatment using a multi‐level structural regulation strategy. The obtained hydrogel is evaluated in the context of respiratory monitoring.

Cellulose nanofiber board

Carbohydrate Polymers, 2018
A cellulose nanofiber board (CNF-board) with a nominal thickness of 3 mm was fabricated without adhesive or additive. To provide comparison, a cellulose fiber board (CF-board) was also fabricated. A novel cold pre-press apparatus was made to dewater highly absorbent CNF gel prior to drying.

Cellulose Nanofibers/Polycarbonate Nanocomposite

Materials Science Forum, 2021
In this study, cellulose nanofiber (CNF) was prepared from carrot residues and further surface modification was carried out using suspension polymerization. Subsequently, these CNFs were added to polycarbonate (PC) to prepare a series CNF reinforced nanocomposites.

TEMPO-oxidized cellulose nanofibers

Nanoscale, 2011
Native wood celluloses can be converted to individual nanofibers 3-4 nm wide that are at least several microns in length, i.e. with aspect ratios>100, by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation and successive mild disintegration in water.
