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 ...

Production of Cellulose Microfibrils by Rhizobium [PDF]

open access: yesApplied Microbiology, 1975
Electron microscope examination of Rhizobium spp. revealed microfibrils produced by flocculating strains but not by nonflocculating strains. The microfibrils from R. trifolii (NA30) were isolated and identified as cellulose by enzymatic, X-ray diffraction, and infrared spectral analyses. Both

Using Solid-State NMR to Understand the Structure of Plant Cellulose. [PDF]

open access: yesJ Am Chem Soc
The structure of plant cellulose microfibrils remains elusive, despite the abundance of cellulose and its utility in industry. Using 2D solid-state NMR of 13C-labeled never-dried plants, six major glucose environments are resolved, which are common to ...

Hydrogen bonds and twist in cellulose microfibrils [PDF]

open access: yesCarbohydrate Polymers, 2017
There is increasing experimental and computational evidence that cellulose microfibrils can exist in a stable twisted form. In this study, atomistic molecular dynamics (MD) simulations are performed to investigate the importance of intrachain hydrogen bonds on the twist in cellulose microfibrils.

Cellulose Microfibril and Micronized Rubber Modified Asphalt Binder

open access: yesFibers, 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]

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.

Probing the molecular architecture of Arabidopsis thaliana secondary cell walls using two- and three-dimensional 13C solid state nuclear magnetic resonance spectroscopy [PDF]

open access: yes, 2015
The plant secondary cell wall is a thickened polysaccharide and phenolic structure, providing mechanical strength to cells, particularly in woody tissues. It is the main feedstock for the developing bioenergy and green chemistry industries.

Cellulose Iβ microfibril interaction with pristine graphene in water: Effects of amphiphilicity by molecular simulation

open access: yes, 2022
Graphene-cellulose interactions have considerable potential in the development of new materials. In previous computational work (Biomacromolecules 2016, 16, 1771), we predicted that the model 100 hydrophobic surface of cellulose interacted favourably ...

Nanostructure of cellulose microfibrils in spruce wood [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
The structure of cellulose microfibrils in wood is not known in detail, despite the abundance of cellulose in woody biomass and its importance for biology, energy, and engineering. The structure of the microfibrils of spruce wood cellulose was investigated using a range of spectroscopic methods coupled to small-angle neutron and wide-angle X-ray ...

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 ...
