Microsphere‐Templated Conductive Syntactic Foams for Recyclable and Additively Manufactured Soft Electronics

Advanced Healthcare Materials, EarlyView.
This work introduces a microsphere‐templated strategy to fabricate reprocessable PEDOT:PSS syntactic foams with tunable porosity, stable conductivity, and 3D printability. In situ PEDOT:PSS coatings create a conductive network that maintains electrical performance at high void fractions.

Study on Vibration Reduction Performance of Gear Pairs Made by a High-Strength Fe-Mn Damping Alloy

Applied Sciences, 2022
Based on the fact that damping alloys can convert mechanical energy into heat energy and dissipate it in materials and the environment, high-strength Fe-Mn damping alloys were used to replace common gear materials to absorb vibration-generated energy ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, EarlyView.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.

The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Microdynamics of Vibrational Damping.

Journal of the Japan Society for Precision Engineering, 1994
マイクロマシソの動力学的設計法確立のため,はり状振動子の減衰特性を解析した.空気抵抗はビーズモデルにより,スクイズカは無限小幅軸受により,内部摩擦は構造減衰により求め,減衰係数の簡便な計算式を導出した.主な結論を以下に示す.(1)はり寸法が小さいとき,減衰力はスクイズカ,空気抵抗,内部摩擦の順に大きい.(2)はり形状を相似形とすると,空気抵抗は長さの-0.5～-1乗に,スクイズカは-1乗に比例し,内部摩擦は寸法に依存しない.(3)イソディシアル応答は減衰比の周波数依存性を無視して計算でき,はり寸法が小さいほど,立上がり時間,整定時間ともに短い.(4)シリコン片持ちはりにおける1次共振の空気抵抗は ...
