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

open access: yesComposites 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 ...

Small Angle Neutron Scattering Reveals Wood Nanostructural Features in Decay Resistant Chemically Modified Wood

open access: yesFrontiers in Forests and Global Change, 2022
While it is known that modifying the hydroxyls in wood can improve the decay resistance; what is often missing in the literature is whether these modifications alter wood nanostructure, and how these changes correlate to the improved decay resistance ...

Wood anatomy of boreal species in a warming world: a review

open access: yesiForest - Biogeosciences and Forestry, 2020
Global warming is affecting tree growth and forest productivity, especially in the Northern boreal ecosystems. Wood quality, which is largely determined by anatomical traits of wood, is vital for the forest industry and global carbon sequestration ...

Multiscale approach including microfibril scale to assess elastic constants of cortical bone based on neural network computation and homogenization method [PDF]

open access: yesInternational Journal for Numerical Methods in Biomedical Engineering, 2014
The complexity and heterogeneity of bone tissue require a multiscale modeling to understand its mechanical behavior and its remodeling mechanisms. In this paper, a novel multiscale hierarchical approach including microfibril scale based on hybrid neural ...

Unusual life cycle and impact on microfibril assembly of ADAMTS17, a secreted metalloprotease mutated in genetic eye disease

open access: yesScientific Reports, 2017
Secreted metalloproteases have diverse roles in the formation, remodeling, and the destruction of extracellular matrix. Recessive mutations in the secreted metalloprotease ADAMTS17 cause ectopia lentis and short stature in humans with Weill-Marchesani ...

Transcriptome profiling of Pinus radiata juvenile wood with contrasting stiffness identifies putative candidate genes involved in microfibril orientation and cell wall mechanics

open access: yesBMC Genomics, 2011
Background The mechanical properties of wood are largely determined by the orientation of cellulose microfibrils in secondary cell walls. Several genes and their allelic variants have previously been found to affect microfibril angle (MFA) and wood ...

Cellulose Microfibril Formation by Surface-Tethered Cellulose Synthase Enzymes.

open access: yesACS Nano, 2016
Cellulose microfibrils are pseudocrystalline arrays of cellulose chains that are synthesized by cellulose synthases. The enzymes are organized into large membrane-embedded complexes in which each enzyme likely synthesizes and secretes a β-(1→4) glucan ...

Unraveling Cellulose Microfibrils: A Twisted Tale [PDF]

open access: yesBiopolymers, 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.

Nanostructural deformation of high-stiffness spruce wood under tension

open access: yesScientific 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 ...

Pipe rheology of microfibrillated cellulose suspensions [PDF]

open access: yesCellulose, 2019
AbstractThe shear rheology of two mechanically manufactured microfibrillated cellulose (MFC) suspensions was studied in a consistency range of 0.2–2.0% with a pipe rheometer combined with ultrasound velocity profiling. The MFC suspensions behaved at all consistencies as shear thinning power law fluids.
