USING HOMOGENIZATION AND NANOINDENTATION FOR MICROFIBRIL ANGLE DETERMINATION OF SPRUCE [PDF]

Acta Polytechnica CTU Proceedings, 2017
This paper is concerned with the evaluation of microfibril angle of spruce. The microfibril angle is defined as an inclination of microfibrils from the longitudinal axis, the direction of lumens.

Intra-annual fluctuation in morphology and microfibril angle of tracheids revealed by novel microscopy-based imaging. [PDF]

PLoS ONE, 2022
Woody cells, such as tracheids, fibers, vessels, rays etc., have unique structural characteristics such as nano-scale ultrastructure represented by multilayers, microfibril angle (MFA), micro-scale anatomical properties and spatial arrangement ...

Investigation of Microfibril Angle of Flax Fibers Using X-Ray Diffraction and Scanning Electron Microscopy

Journal of Natural Fibers, 2020
Microfibril angle (MFA) of secondary cell wall has an important effect on the mechanical properties of flax fibers. It is therefore essential to study the relationships between MFA and mechanical properties.

Measurement of microfibril angle in plant fibres: Comparison between X-ray diffraction, second harmonic generation and transmission ellipsometry microscopies

Composites Part C: Open Access, 2023
The orientation of cellulose microfibrils within plant fibres is one of the main factors influencing their mechanical properties. As plant fibres are more and more used as reinforcement for agro-composites, their mechanical properties have a strong ...

Microfibril angle of Eucalyptus grandis wood in relation to the cambial age [PDF]

Maderas: Ciencia y Tecnología, 2014
The microfibril angle (MFA) of wood is an important feature, which helps to explain the physical and mechanical behaviour of wood in use. It has been little investigated for wood produced in Brazil, mainly for mature trees.

Microfibril angle and density patterns of fertilized and irrigated Norway spruce [PDF]

Silva Fennica, 2004
Two Norway spruce nutrient optimisation trials, one in the north of Sweden and one in the south, were used to study the effects of intensive growth and fertilization on wood density and microfibril angle.

SANS investigation of fungal loosenins reveals substrate-dependent impacts of protein action on the inter-microfibril arrangement of cellulosic substrates [PDF]

Biotechnology for Biofuels and Bioproducts
Background Microbial expansin-related proteins include fungal loosenins, which have been previously shown to disrupt cellulose networks and enhance the enzymatic conversion of cellulosic substrates.

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

Composites 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 ...

WITHIN TREE VARIATION OF LIGNIN, EXTRACTIVES, AND MICROFIBRIL ANGLE COUPLED WITH THE THEORETICAL AND NEAR INFRARED MODELING OF MICROFIBRIL ANGLE [PDF]

IAWA Journal, 2007
A theoretical model was built predicting the relationship between microfibril angle and lignin content at the Angstrom (Å) level. Both theoretical and statistical examination of experimental data supports a square root transformation of lignin to predict microfibril angle.

Integrating genomic information and productivity and climate-adaptability traits into a regional white spruce breeding program

PLoS ONE, 2022
Tree improvement programs often focus on improving productivity-related traits; however, under present climate change scenarios, climate change-related (adaptive) traits should also be incorporated into such programs.
