X-Ray Diffraction Methods for Microfibril Angle Measurement in Maize and Sorghum Stalks

Agronomy
Stalk lodging (the structural failure of plant stems prior to harvest) remains a major constraint to global cereal crop production, reducing yields, impairing grain quality, and increasing harvest losses. Since cellulose microfibrils are the primary load-

Transcriptome profiling of Pinus radiata juvenile wood with contrasting stiffness identifies putative candidate genes involved in microfibril orientation and cell wall mechanics

BMC Genomics, 2011
Background The mechanical properties of wood are largely determined by the orientation of cellulose microfibrils in secondary cell walls. Several genes and their allelic variants have previously been found to affect microfibril angle (MFA) and wood ...

Study on the Variation Pattern and Influencing Factors of Poisson’s Ratio of Bamboo

Frontiers in Materials, 2022
As a natural polymer material, bamboo is regarded as a super material with lightweight but excellent mechanical properties. With the increasing application of bamboo in structures, high-strength composite materials, bridges, musical instruments, and ...

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

Journal 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

Microfibril Angles in the S2 layer of tracheids in Root and Stem Wood of Chamaecyparis obtusa: Prediction of microfibril angle of mature wood in the stem from root wood

Mokuzai Gakkaishi, 2005
ヒノキ根材と幹材において, 晩材仮道管二次壁中層のミクロフィブリル傾角 (MFA) の放射方向変動と樹高方向および根端方向の変動を調べた。胸高部位では20年輪目前後でMFAは安定した。地上高が高くなるとMFAの安定時期は早まり, 8m部位では10年輪目前後で安定した。しかし, MFAの安定値には地上高による差異がなかった。根材では10年輪目前後でMFAは安定し, 基部からの距離や径の大きさに関わらず, 安定値や安定時期に大差は見られなかった。採取が容易な基部から根端側へ20cm部位の根材を使って, 幹の成熟材部の予測可能性を検討した結果, 根材の安定値と幹材の安定値との間に1%レベルで有意な相関関係が認められた。順位相関もまた1%レベルで有意であった。根材の18 ...

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Microfibril orientation dominates the microelastic properties of human bone tissue at the lamellar length scale. [PDF]

PLoS ONE, 2013
The elastic properties of bone tissue determine the biomechanical behavior of bone at the organ level. It is now widely accepted that the nanoscale structure of bone plays an important role to determine the elastic properties at the tissue level.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

Advanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Flax Composites With Improved Interfacial Strength Through Microbially Induced Mineral Precipitation

Advanced Materials, EarlyView.
A bio‐inspired biomineralization strategy introduces an additional hierarchy to flax fiber composites. By controlling microbe‐mediated mineral particle deposition through tuned salt concentrations, stress transfer within the natural fiber composite is enhanced.
