Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

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.

Experimental Studies on Composite Propellants
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。
