Durability evaluation of natural-durable wood species by a fungus cellar test

Wood Preservation, 2006
ファンガスセラー試験は,保存処理木材の耐朽性の評価方法として日本の公的規格にも採用されるなど,野外試験に比較して実用的な結果が短時間で得られる手法とされている。本研究では,通常のファンガスセラー試験において,目視による評価,質量減少率の定期的かつ継続的測定を行うことにより,高耐朽性樹種のより詳細な耐朽性の評価を試みた。試験の結果,高耐朽性樹種は比較的高い耐朽性を示したが,イペ,ブラウナが高い耐朽性を示したのに対し,キャブレーバ,ジャラは低い耐朽性を示すなど,その耐朽性には樹種間で相違が見られた。ヒノキ心材にはスギ心材と同程度の耐朽性を示すものもあり,耐朽性が求められる構造材料として使用する場合には,保存処理等の配慮が必要であることが示唆された。本報告のファンガスセラー試験は ...

Broadband, Flexible, Skin‐Compatible Carbon Dots/Graphene Photodetectors for Wearable Applications

Advanced Functional Materials, EarlyView.
Broadband, flexible photodetectors integrating nitrogen‐rich carbon dots with single‐layer graphene on plastic substrates are demonstrated. A biocompatible chitosan–glycerol electrolyte enables efficient low‐voltage gating and on‐skin operation. The devices exhibit ultraviolet‐to‐near‐infrared response, mechanical robustness under bending, and verified

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

Advanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

Dual‐Atom Dopants Activated Ruthenium Single‐Atom Alloy Boosting Hydrogen Evolution Electrocatalysis in Proton Exchange Membrane Water Electrolyzer

Advanced Functional Materials, EarlyView.
Ni1‐Bi1 dual‐atom dopants are achieved for activating Ru lattices without blocking noble atoms. This model exhibits an ultralow overpotential of 11.4 mV and superb stability at 10 mA cm−2 toward hydrogen evolution reaction, enabling a proton exchange membrane water electrolyzer that needs only 2.233 V to reach 3.0 A cm−2 and operates stably at 1.0 A cm−
