THE SIZE OF THE CELLULOSE MICROFIBRIL [PDF]

open access: yesThe 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.

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

open access: yes, 2013
The complexity and heterogeneity of bone tissue require a multiscale modelling to understand its mechanical behaviour and its remodelling mechanisms.

Processing of Polymer Nanocomposites Reinforced with Polysaccharide Nanocrystals

open access: yesMolecules, 2010
Aqueous suspensions of polysaccharide (cellulose, chitin or starch) nanocrystals can be prepared by acid hydrolysis of biomass. The main problem with their practical use is related to the homogeneous dispersion of these nanoparticles within a polymeric ...

Proteolysis of fibrillin-2 microfibrils is essential for normal skeletal development

open access: yeseLife, 2022
The embryonic extracellular matrix (ECM) undergoes transition to mature ECM as development progresses, yet few mechanisms ensuring ECM proteostasis during this period are known.

XTH acts at the microfibril-matrix interface during cell elongation [PDF]

open access: yes, 2005
Sulphorhodamine-labelled oligosaccharides of xyloglucan are incorporated into the cell wall of Arabidopsis and tobacco roots, and of cultured Nicotiana tabacum cells by the transglucosylase (XET) action of XTHs.

Homogenization of a system of elastic and reaction-diffusion equations modelling plant cell wall biomechanics [PDF]

open access: yes, 2015
In this paper we present a derivation and multiscale analysis of a mathematical model for plant cell wall biomechanics that takes into account both the microscopic structure of a cell wall coming from the cellulose microfibrils and the chemical reactions

Spatial organization of cellulose microfibrils and matrix polysaccharides in primary plant cell walls as imaged by multichannel atomic force microscopy.

open access: yesThe Plant Journal, 2016
We used atomic force microscopy (AFM), complemented with electron microscopy, to characterize the nanoscale and mesoscale structure of the outer (periclinal) cell wall of onion scale epidermis - a model system for relating wall structure to cell wall ...

Direct Measurement of Plant Cellulose Microfibril and Bundles in Native Cell Walls

open access: yesFrontiers in Plant Science, 2020
Plants use rigid cellulose together with non-cellulosic matrix polymers to build cell walls. Cellulose microfibrils comprise linear β(1,4)-glucan chains packed through inter- and intra-chain hydrogen-bonding networks and van der Waals forces.

Mechanical adaptations of cleavers (Galium aparine) [PDF]

open access: yes, 2004
• Background and Aims Cleavers (Galium aparine) is a fast-growing herbaceous annual with a semi-self-supporting, scrambling-ascending growth habit. Mature plants often use upright species for support. It is common in hedgerows and on waste ground. This
