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 ...

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.

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 ...

Slow crack growth : models and experiments [PDF]

open access: yes, 2007
The properties of slow crack growth in brittle materials are analyzed both theoretically and experimentally. We propose a model based on a thermally activated rupture process.

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 ...

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.

MFC concept as a possible solution for closed-loop recycling of food packaging trays [PDF]

open access: yes, 2020
Flexible plastic films from food packaging trays make up one of the largest fractions of the plastic waste stream and recycling is one of the most important actions to deal with this fraction, reducing the impact of these plastics on the environment ...

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

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.

Plant cell walls: impact on nutrient bioaccessibility and digestibility [PDF]

open access: yes, 2020
Cell walls are important structural components of plants, affecting both the bioaccessibility and subsequent digestibility of the nutrients that plant-based foods contain.
