The current work demonstrates an innovative approach to develop nanocellulose based membranes <italic>via in situ</italic> TEMPO functionalization of the thin functional layer cellulose nanocrystals (CNC<sub>BE</sub>) enhance metal ion adsorption capacity.
Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can manufactured as simply producing paper? Here the production of membranes nanocellulose by applying a papermaking process is demonstrated. Manufacture nanopapers was enabled inducing flocculation nanofibrils upon addition trivalent ions.
Humidity is an efficient instrument for facilitating changes in local architectures of two-dimensional surfaces assembled from nanoscaled biomaterials. Here, complementary surface-sensitive methods are used to collect explicit and precise experimental evidence on the water vapor sorption into (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) oxidized cellulose nanofibril (CNF) thin film over relative humidity (RH) range 0 97%. Changes thickness mass due uptake tracked using spectroscopic...
We report the viscoelastic properties of core-shell-structured, hemicellulose-rich nanofibrillated cellulose (NFC) in dispersion and wet-film states. The NFC (hemicellulose neutral sugars 23%, carboxylate 0.2 mmol g(-1)), prepared from Japanese persimmons, had a core crystallite thickness 2.3 nm unit fibril 4.2 nm. A carboxylate-rich 7%, 0.9 g(-1)) with widths 2.5 3.3 nm, respectively, was used as reference. solid-concentration dependencies storage moduli gel-like water dispersions were...
Porous, transparent plant-based template constructed from cellulose nanofibrils acts as a versatile matrix for immobilization of H<sub>2</sub>-producing cyanobacteria and green algae.
The goal of this study was to assess the sustainability a modified cellulose nanofiber material for recovery precious gold from chloride solution, with special focus on acidic solutions generated by cupric and ferric leaching processes. TEMPO-oxidized in hydrogel (TOCN), dry (H-TOCN, F-TOCN) sheet form (S-TOCN) examined adsorptivity solution. Additionally, work describes optimum conditions parameters recovery. data obtained investigation are also modeled using kinetic (pseudo first-order...
A simple and inexpensive method for producing water-stable pulp fibre yarns using a deep eutectic mixture composed of choline chloride urea (ChCl/urea) was developed in this work.Deep solvents (DESs) are mixtures consisting two or more components that together have lower melting point than the individual components.DESs been previously studied with respect to cellulose dissolution, functionalisation, pre-treatment.This new uses urea, which is used as swelling dispersing agent fibres...
The wide use of magnesium and magnesium-based alloys for bio-implant materials has so far been restricted due to the rapid corrosion rate such under in-vivo conditions 1,2 . Cellulose based coatings have previously examined as although TEMPO-oxidised nano-fibrillated cellulose (CNF-TEMPO) yet be explored 3,4 work outlines details an investigation in effect that deposition method on coating characteristics. Three different methods were used deposit CNF-TEMPO including adsorption, spin anodic...
