Strengthened Interfacial Coupling Between Self‐Assembled Monolayers and Bulk Heterojunctions Enables Thermally Stable Organic Solar Cells

Advanced Materials, EarlyView.
Molecularly engineered self‐assembled monolayers (SAMs) featuring extended conjugated terminals facilitate superior interfacial coupling with the organic solar cell active layer. By physically anchoring the local morphology, this design suppresses thermal degradation, allowing devices to operate at 85°C for 150 h before degrading to 90% of their ...

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

Advanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

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。
