Preferred crystallographic orientation of cellulose in plant primary cell walls

open access: yesNature Communications, 2020
Cellulose is synthesized as microfibrils of β-1,4-linked glucan chains arranged in a crystalline lattice. Here Ye et al. use grazing incidence wide angle X-ray scattering to show that cellulose crystals are preferentially orientated parallel to the plant

Failure of Mineralized Collagen Microfibrils Using Finite Element Simulation Coupled to Mechanical Quasi-brittle Damage [PDF]

open access: yes, 2011
Bone is a multiscale heterogeneous materiel of which principal function is to support the body structure and to resist mechanical loading and fractures. Bone strength does not depend only on the quantity and quality of bone which is characterized by the ...

Nanoscale Movements of Cellulose Microfibrils in Primary Cell Walls

open access: yesNature Plants, 2017
The growing plant cell wall is commonly considered to be a fibre-reinforced structure whose strength, extensibility and anisotropy depend on the orientation of crystalline cellulose microfibrils, their bonding to the polysaccharide matrix and matrix ...

Cell proliferation, cell shape, and microtubule and cellulose microfibril organization of tobacco BY-2 cells are not altered by exposure to near weightlessness in space [PDF]

open access: yes, 2009
The microtubule cytoskeleton and the cell wall both play key roles in plant cell growth and division, determining the plant’s final stature. At near weightlessness, tubulin polymerizes into microtubules in vitro, but these microtubules do not self ...

Structural and compositional diversity of fibrillin microfibrils in human tissues

open access: yesJournal of Biological Chemistry, 2018
Elastic fibers comprising fibrillin microfibrils and elastin are present in many tissues, including the skin, lungs, and arteries, where they confer elasticity and resilience.

Spatial relationships between polymers in Sitka spruce: proton spin-diffusion studies [PDF]

open access: yes, 2006
The spatial arrangement of polymers in Sitka spruce (Picea sitchensis) was investigated by NMR proton spin-diffusion studies, supplemented by deuterium-exchange experiments monitored by FTIR spectroscopy.

Discerning the subfibrillar structure of mineralized collagen fibrils: a model for the ultrastructure of bone. [PDF]

open access: yesPLoS ONE, 2013
Biomineralization templated by organic molecules to produce inorganic-organic nanocomposites is a fascinating example of nature using bottom-up strategies at nanoscale to accomplish highly ordered multifunctional materials. One such nanocomposite is bone,

Liquid Crystalline Granules Align in a Hierarchical Structure To Produce Spider Dragline Microfibrils.

open access: yesBiomacromolecules, 2017
The spider silk spinning process converts spidroins from an aqueous form to a tough fiber. This spinning process has been investigated by numerous researchers, and micelles or liquid crystals of spidroins have been reported to form silk fibers, which are
