Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

Investigation into the effect of the grout properties injected behind the segment on surface settlement in mechanized tunneling

International Journal of Geo-Engineering
Ground surface settlement is one of the inevitable components of shallow excavations in soil environments. It is crucial to predict the amount of ground surface settlement in mechanized tunneling for urban subway construction.

EVALUATION OF THE PREVENTIVE METHOD FOR GROUND SURFACE SETTLEMENT BY EXCAVATION OF SHALLOW TUNNEL IN UNCONSOLIDATED GROUND

Doboku Gakkai Ronbunshu, 1999
都市域においてトンネルを掘削する場合, 重要構造物と交差したり近接することは通例であり, 地表面沈下の問題は避けて通れない重要課題である. 特に, 土被りが浅い未固結地山の場合, 地質による影響を強く受けた特異な非線形的な変位挙動を示す場合が多い. このような状況から, 地表面沈下に対する対応が困難で, 対症療法的な対策を迫られる場合も散見されるが, 本質的には沈下のメカニズムを把握することが重要な課題である. 本論文では, 洪積砂層と盛土層の2つの異なった地山において採用された抑止対策 (掘削工法によるものとしてCD工法とその改良工法であるCRD工法の2例, 補助工法によるもの1例) を例として逆解析を実施し, 地表面沈下のメカニズムおよび各抑止工法に対する効果を明らかにした.

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 ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Numerical and analytical investigation of ground surface settlement due to subway excavation

, 2012
In the congested urban areas, tunnelling close to existing structures often occurs due to the lack of space. Consequently, tunnelling-induced ground movements may cause serious damage to the adjacent structures. Ground surface settlement caused by tunnel
