Unveiling Multidimensional Physicochemical Design Principles for Tissue Processing Hydrogels
Advanced Functional Materials, EarlyView.This study establishes a materials‐based design framework for polymer hydrogels in tissue clearing, linking physicochemical properties to performance in tissue processing, labeling, and imaging. By analyzing rheology, swelling, porosity, antibody diffusion, mechanical performance, and thermochemical stability across platforms, this work provides a ...

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Experimental Studies on Composite Propellants
The Journal of the Society of Chemical Industry, Japan, 1960 酸化剤に過塩素酸アンモン,燃料結合剤にポリエステル樹脂またはエポキシーポリスルフィド樹脂を用いたコンポジット推進薬の物性および燃焼特性を実験的に検討した。この結果次の点を明らかにした。すなわち燃料結合剤として用いる樹脂の性質に極端な差がないかぎり,成形推進薬の物性は特に差は認められない。また燃焼特性に関しては,これらの推進薬の圧力指数はいずれも小さく,したがって燃焼の安定性を期し得るが,面積比等しい時の比推力を考える時,エポキシ-ポリスルフィド系推進薬の方がポリエステル系推進薬よりすぐれているといえよう。

Dispensing Volumetric Additive Manufacturing
Advanced Functional Materials, EarlyView.Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...
