Journal ArticleDOI
Enzymatic hydrolysis combined with mechanical shearing and high-pressure homogenization for nanoscale cellulose fibrils and strong gels.

TL;DR: Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.
Journal ArticleDOI
Assignment of non-crystalline forms in cellulose I by CP/MAS 13C NMR spectroscopy
TL;DR: In this paper, non-crystalline forms of cellulose in birch pulp, cotton linters and Cladophora sp were studied by CP/MAS 13 C NMR spectroscopy.
Journal ArticleDOI
A CP/MAS13C NMR investigation of molecular ordering in celluloses
TL;DR: The spectral behavior of this cellulose form indicates it is a less-ordered or a para-crystalline ‘in core’ structure with a somewhat larger mobility than the crystalline cellulose Iα and Iβ allomorphs.
Journal ArticleDOI
Ultra porous nanocellulose aerogels as separation medium for mixtures of oil/water liquids
TL;DR: In this paper, a novel type of sponge-like material for the separation of mixed oil and water liquids has been prepared by the vapour deposition of hydrophobic silanes on ultra-porous nanocellulose aerogels.

TL;DR: Efficient stress transfer from macroscale to individual CNF due to cross-linking and high degree of order enables their Young's modulus to reach up to 86 GPa and a tensile strength of 1.57 GPa, exceeding the mechanical properties of known natural or synthetic biopolymeric materials.
