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 ...

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 ...

Covalent Bonds Reinforced Strength and Modulus of Heterocyclic Aramid Fiber by Interfacial Aminated‐MXene Nanosheets

Advanced Science, EarlyView.
We demonstrate the covalent bonds strategy to enhance the mechanical property of PBIA fiber by using interfacial MXene‐NH2 nanosheets. The MXene‐NH2 nanosheets with reactive amino sites that can serve as nucleating agents and chain anchors to enhance orientation, crystallinity and interchain interaction of PBIA fiber via strong interfacial amido ...

Variation of Cellulose Microfibril Angles in Softwoods and Hardwoods—A Possible Strategy of Mechanical Optimization [PDF]

Journal of Structural Biology, 1999
Position-resolved small-angle X-ray scattering was used to investigate the nanostructure of the wood cell wall in two softwood species (Norwegian spruce and Scots pine) and two hardwood species (pedunculate oak and copper beech). The tilt angle of the cellulose fibrils in the wood cell wall versus the longitudinal cell axis (microfibril angle) was ...
