Hyperelastic Starch Hydrogel Configures Edible and Biodegradable All‐Components for Soft Robots

Advanced Science, EarlyView.
Hyperelastic starch hydrogel is tailored via a phase separation strategy of solvent‐antisolvent co‐modulation. The mechanical performance of starch hydrogel is widely tuned with maximum strains: 194.4–361.4%; maximum tensile stresses: 34–192 kPa; and Young's moduli: 36.0–205.8 kPa. Notably, the hydrogel achieves complete soil degradation within 24 days

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

Advanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

A Lung‐Immune Dual‐Humanized Mouse Using Cryopreserved Tissue Enables Infection and Immune Profiling of Human Common Cold Coronaviruses

Advanced Science, EarlyView.
Cryopreserved lung‐humanized mice overcome the dependency to fresh tissues and permit head‐to‐head profiling of all four human common cold coronaviruses versus SARS‐CoV‐2 infection; the model validates Paxlovid efficacy against HKU1 and, when coupled with human immune‐system engraftment, enables interrogation of lung‐resident human immunity and HKU1 ...

Beyond Catalytic Therapy: Copper‐Paeonol Nanozymes Disrupt Fascin‐Mediated Actin Bundling to Suppress Tumor Growth and Metastasis

Advanced Science, EarlyView.
Copper‐paeonol nanozymes target tumor‐specific reactive oxygen species generation and disrupt fascin‐mediated actin bundling, effectively suppressing tumor growth and metastatic colonization. Abstract Fascin, an actin‐bundling protein universally upregulated in metastatic tumors, drives tumor migration and invasion by promoting filopodia and ...

Drawing of Regenerated Cellulose Fibers

The Journal of the Society of Chemical Industry, Japan, 1960
ビスコースレーヨンの延伸時における挙動と微細組織との関係を知るために, 凝固力の異なる浴を用いてつくられた3種の等方性モデル糸を, ザンテート状態および再生膨潤状態で延伸して, 膨潤度, 配向度, 結晶化度などの変化を測定した。この3種のモデル糸の等方性状態における微細組織の相違は膨潤度においていちじるしく,結晶の大きさボやや異なるが結晶化度は大差ないと考えられているものである。これらを延伸し乾燥した場合,結晶化度は変化しないがセグメント配向の増加のしかたがそれぞれことなり,概して高膨潤度のものの方が同じ延伸率に対して低い配向度を与えることを認めた。また再生状態よりもザンテート状態で延伸する方が延伸効率は悪いが高延伸率,高配向度のものが得られやすい ...
