Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...

MOF‐Derived Cu‐TiO2/Alginate Micromotors for Buoyancy‐Regulated 3D Motion

Advanced Science, EarlyView.
In this work, cyanobacteria‐inspired sodium alginate (SA)/Cu‐TiO2/Fe3O4 hydrogel micromotors generate and encapsulate O2 microvesicles upon light irradiation, enabling buoyancy‐mediated Z‐axis upward migration and surface enrichment at the light‐exposed water‐air surface.

Study of the sol-gel sol-gel transition of kappa-carraghenane

, 1982
Cette thèse porte sur la structure, les propriétés en solution et le mécanisme de gélification des carraghénanes, des polysaccharides extraits d’algues rouges et largement utilisés pour leurs propriétés épaississantes et gélifiantes. Le travail se concentre particulièrement sur le κ-carraghénane (kappa-carraghénane) et cherche à comprendre les ...

Freestanding Hierarchical‐Porous BCZT Thin Films Enable Efficient Ultrasonic Energy Harvesting in Soft Tissue

Advanced Science, EarlyView.
Freestanding hierarchical‐porous BCZT thin films integrate a compliant porous surface with a dense piezoceramic backbone to balance mechanical reliability, voltage sensitivity, and acoustic coupling. The films enable stable wearable pulse‐wave monitoring and enhanced tissue‐coupled ultrasonic energy harvesting, offering a promising route toward soft ...

Restoration of m6A‐Modified circPSMB1 Suppresses Chordoma Progression and Enables Local Nanotherapeutic Intervention

Advanced Science, EarlyView.
An m6A‐modified circRNA, circPSMB1, is identified as a tumor suppressor in chordoma. METTL3‐dependent m6A promotes circPSMB1 interaction with HNRNPA2B1, limiting c‐MYC expression and malignant progression. An injectable HMnO2‐based nanohydrogel enables local circPSMB1 delivery and tumor microenvironment‐responsive therapy, offering a promising strategy
