Cellulose Microfibril Angle in Wood and Its Dynamic Mechanical Significance

open access: yes, 2013
The orientation of the cellulose microfibrils in the S2 layers of the cell walls of softwood has a significant influence on the mechanical properties of wood.

P10.05 REDUCED MOLECULAR FLEXIBILITY IN THE LARGE ARTERIES OF DIABETIC RATS

open access: yesArtery Research, 2009
In Type 1 and 2 diabetes tissue stiffening is evident from measurements of the gross mechanical properties of the vasculature. In general, pathological glycosylation of extracellular matrix proteins may play an important role in increasing stiffness in ...

The role of calcium in the organization of fibrillin microfibrils

open access: yesFEBS Letters, 1993
The microfibrillar glycoprotein fibrillin has a multidomain structure which contains forty‐three epidermal growth factor‐like motifs with calciumbinding consensus sequences. We have utilized intact microfibrils isolated from human dermal fibroblast cultures to investigate the putative influence of bound calcium on microfibrillar organization and ...

Relationships between microfibril angle, modulus of elasticity and compressive strength in Eucalyptus wood

open access: yesMaderas: Ciencia y Tecnología, 2012
Many traits are known to be important in determining the value of Eucalyptus wood as sawn timber. The commercial importance of the microfibril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood ...

On the strain-induced fibrillar microstructure of polyethylene: Influence of chemical structure, initial morphology and draw temperature

open access: yeseXPRESS Polymer Letters, 2016
The influence of crystalline microstructure and molecular topology on the strain-induced fibrillar transformation of semi-crystalline polyethylenes having various chemical structures including co-unit content and molecular weight and crystallized under ...

Microfibril Angle: Measurement, Variation and Relationships – A Review

open access: yes, 2008
Microfibril angle (MFA) is perhaps the easiest ultrastructural variable to measure for wood cell walls, and certainly the only such variable that has been measured on a large scale.

Growth stresses and cellulose structural parameters in tension and normal wood from three tropical rainforest angiosperm species

open access: yesBioResources, 2007
Few studies have been conducted about relation between cellulose para-meters and biomechanical properties of wood in tropical angiosperms species. For this purpose, on 13 trees from 3 species of French Guyana tropical rainforest in a clear active process

MODULUS OF ELASTICITY AND HARDNESS OF COMPRESSION AND OPPOSITE WOOD CELL WALLS OF MASSON PINE

open access: yesBioResources, 2012
Compression wood is commonly found in Masson pine. To evaluate the mechanical properties of the cell wall of Masson pine compression and opposite wood, nanoindentation was used. The results showed that the average values of hardness and cell wall modulus
