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.

Unravelling the nanostructure of cellulose microfibrils [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Cellulose is the most abundant naturally occurring polymer and has diverse applications in biology, energy and engineering. The cellulose nanostructure has implications on the mechanical strength of natural materials such as wood and nanocelluloses are also being used to create high-performance composite materials with properties comparable to aramid ...

Comparative studies on wood structure and microtensile properties between compression and opposite wood fibers of Chinese fir plantation

open access: yesJournal of Wood Science, 2021
The microtensile properties of mechanically isolated compression wood (CW) and opposite wood (OW) tracheids of Chinese fir (Cunninghamia lanceolata) were investigated and discussed with respect to their structure. Major differences in the tensile modulus

Development of colorless wood via two-step delignification involving alcoholysis and bleaching with maintaining natural hierarchical structure

open access: yesJournal of Wood Science, 2020
Lignin-free wood has been successfully developed via a two-step chemical treatment while maintaining its inherent hierarchical structure. The first step was alcoholysis which was conducted using ethylene glycol, and whose condition was optimized by ...

A Structurally Specialized Uniform Wall Layer is Essential for Constructing Wall Ingrowth Papillae in Transfer Cells

open access: yesFrontiers in Plant Science, 2017
Transfer cells are characterized by wall labyrinths with either a flange or reticulate architecture. A literature survey established that reticulate wall ingrowth papillae ubiquitously arise from a modified component of their wall labyrinth, termed the ...

Combined analysis of microstructures within an annual ring of Douglas fir (Pseudotsuga menziesii) by dynamic mechanical analysis and small angle X-ray scattering

open access: yesJournal of Wood Science, 2022
Dynamic mechanical analysis (DMA) and small angle X-ray scattering (SAXS) measurements of water-saturated wood of Douglas fir (Pseudotsuga menziesii) in the temperature range of 0 ℃ to 100 ℃ were focused to clarify microstructural changes within an ...

Effect of drying conditions on cellulose microfibril aggregation and "€œhornification"

open access: yes, 2018
Drying of chemical pulps results in a decreased swelling of the fibres, leading to lower density and strength properties of paper sheets. To investigate how variation of pulp pH, drying process temperature, and final moisture content affect this ...
