Influence of defects on the tensile behaviour of flax fibres: Cellulose microfibrils evolution by synchrotron X-ray diffraction and finite element modelling

Composites Part C: Open Access, 2022
The cellulose microfibril realignment of unitary flax fibres with contrasted density of structural defects, which are also known as dislocations and defined as zones of microstructure heterogeneities, was investigated upon tensile testing by means of X ...

Fabrication of Ionic Cellulose Nanofiber Composites by Electrospinning Cellulose Microfibril-Gel-Dispersions in Poly(vinyl Alcohol) Solution

Journal of Natural Fibers, 2022
In this study, we propose a fabrication method to obtain composites of poly(vinyl alcohol) (PVA)/ionic cellulose nanofibers, in which a fiber structure is manipulated through a reconstruction of 2,2,6,6-tetramethyl-piperidinyl-1-oxyl radical (TEMPO ...

Xylan Is Critical for Proper Bundling and Alignment of Cellulose Microfibrils in Plant Secondary Cell Walls

Frontiers in Plant Science, 2021
Plant biomass represents an abundant and increasingly important natural resource and it mainly consists of a number of cell types that have undergone extensive secondary cell wall (SCW) formation. These cell types are abundant in the stems of Arabidopsis,

Nanostructural deformation of high-stiffness spruce wood under tension

Scientific Reports, 2021
Conifer wood is an exceptionally stiff and strong material when its cellulose microfibrils are well aligned. However, it is not well understood how the polymer components cellulose, hemicelluloses and lignin co-operate to resist tensile stress in wood ...

Cellulose Microfibril and Micronized Rubber Modified Asphalt Binder

Fibers, 2021
Cellulose microfibrils (CMFs) and micronized rubber powder (MRP) can be derived from low or negative-cost agricultural/industrial waste streams and offer environment-friendly and cost-effective pathways to develop engineering products.

THE SIZE OF THE CELLULOSE MICROFIBRIL [PDF]

The Journal of Cell Biology, 1963
Recently the lateral width of the cellulose microfibril has been estimated as 30 A rather than about 150 to 200 A, by extrapolation of data from model shadowing experiments. The difference was attributed to a layer of metal deposited during shadowing.

DEFECTIVE KERNEL1 regulates cellulose synthesis and affects primary cell wall mechanics

Frontiers in Plant Science, 2023
The cell wall is one of the defining features of plants, controlling cell shape, regulating growth dynamics and hydraulic conductivity, as well as mediating plants interactions with both the external and internal environments.

Unraveling Cellulose Microfibrils: A Twisted Tale [PDF]

Biopolymers, 2013
ABSTRACTMolecular dynamics (MD) simulations of cellulose microfibrils are pertinent to the paper, textile, and biofuels industries for their unique capacity to characterize dynamic behavior and atomic‐level interactions with solvent molecules and cellulase enzymes.

Comparative studies on wood structure and microtensile properties between compression and opposite wood fibers of Chinese fir plantation

Journal of Wood Science, 2021
The microtensile properties of mechanically isolated compression wood (CW) and opposite wood (OW) tracheids of Chinese fir (Cunninghamia lanceolata) were investigated and discussed with respect to their structure. Major differences in the tensile modulus
