Yielding and flow of cellulose microfibril dispersions in the presence of a charged polymer

, 2016
The shear flow of microfibrillated cellulose dispersions is still not wholly understood as a consequence of their multi-length-scale heterogeneity. We added carboxymethyl cellulose, a charged polymer, that makes cellulose microfibril dispersions more ...

Ethylene Signaling Is Required for Fully Functional Tension Wood in Hybrid Aspen

Frontiers in Plant Science, 2019
Tension wood (TW) in hybrid aspen trees forms on the upper side of displaced stems to generate a strain that leads to uplifting of the stem. TW is characterized by increased cambial growth, reduced vessel frequency and diameter, and the presence of ...

Xyloglucan Is Not Essential for the Formation and Integrity of the Cellulose Network in the Primary Cell Wall Regenerated from Arabidopsis Protoplasts

Plants, 2020
The notion that xyloglucans (XG) play a pivotal role in tethering cellulose microfibrils in the primary cell wall of plants can be traced back to the first molecular model of the cell wall proposed in 1973, which was reinforced in the 1990s by the ...

Stronger cellulose microfibril network structure through the expression of cellulose-binding modules in plant primary cell walls

, 2019
Cellulose-binding modules (CBMs) are non-catalytic domains typically occurring in glycoside hydrolases. Their specific interaction with diverse polysaccharides assists hydrolysis by the catalytic subunits. In this work, we have exploited the interactions

Determination of the Combined Effect of Chemical Modification and Compression of Agatis Wood on the Dimensional Stability, Termite Resistance, and Morphological Structure

BioResources, 2014
Agatis wood (Agathis lorantifolia Salisb.) was impregnated with a combination of styrene and methyl methacrylate and compressed to a strain of 50% to improve dimensional stability and termite resistance.

Structure of cellulose microfibrils in mature cotton fibres [PDF]

Carbohydrate Polymers, 2017
The structure of cellulose microfibrils in mature cotton fibres from three varieties - Gossypium hirsutum, G. barbadense and G. arboreum - has been investigated by a multi-technique approach combining small angle scattering techniques with spectroscopy and diffraction.

Cellulose microfibril deposition: coordinated activity at the plant plasma membrane

, 2008
Plant cell wall production is a membrane-bound process. Cell walls are composed of cellulose microfibrils, embedded inside a matrix of other polysaccharides and glycoproteins.

Cellulose structural arrangement in relation to spectral changes in tensile loading FTIR

, 2009
In order to utilise wood and wood fibres in advanced materials, a better understanding of the mechanical material characteristics and the interactions among the components is necessary. For this purpose, FTIR was explored together with mechanical loading

Composition analysis, mechanical properties, and water absorption kinetics of extracted cellulosic fibers from Calamus deerratus cane as biodegradable reinforcement alternatives

Next Materials
This study aims to fill a research gap on the genus Calamus by providing a detailed elucidation on one of the insufficiently explored species, namely Calamus (C.) deerratus fiber. This investigation encompasses the chemical composition, fiber extraction,
