Interconnected Porous Hydrogels with Tunable Anisotropy Through Aqueous Emulsion Bioprinting
Advanced Functional Materials, EarlyView.A 3D bioprintable microporous bioink is developed using an aqueous two‐phase system (ATPS) composed of extracellular matrix (ECM) mimetic biopolymers. The ATPS bioink enables the fabrication of interconnected porous architectures with up to 70% porosity, supporting long‐term cell viability and 3D cell alignment, enabling a simultaneous generation of ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment
Advanced Functional Materials, EarlyView.Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Some Properties of Ultra Clean Spring Steel
Transactions of Japan Society of Spring Engineers, 1985 乗用車用懸架ばねの高応力化指向, 弁ばねのパワーアップ指向は, 両者の要求レベルに差はあるとはいえ, いずれも耐久性の向上が共通した目標である. これを達成するには, 素材であるばね鋼の超清浄鋼化が1つの有力な手段であると考えられる.そこで, 低コスト・大量生産を前提とした脱ガス法を一般ばね鋼に適用して超清浄鋼を製造し, 懸架ばね用あるいは弁ばね用素材としての特性を検討した. その結果,(1) 200kgf/mm2級高強度懸架ばね用材料として, 酸素レベルを15ppm以下に下げたULO鋼が1つの有効な手段であるとの見通しを得た.(2) 低酸素化 (ULO) および低TiN化 (UL・TiN) 処理を適用したULO+UL・TiN鋼は, 疲れ強さがVAR材なみになることを確認し ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...
