Ionic Highways under Multivariate‐Coupled Strategies: Ultrahigh Power Generation from Industrial Waste Liquors Using Robust COF Membranes

Advanced Science, EarlyView.
This study presents a multivariate‐coupled strategy to fabricate TB‐COF membranes with tunable charge density via uniformly distributed Bpy groups, enabling efficient ion transport and energy harvesting. The robust β‐ketoenamine‐linked structure ensures stability, achieving power outputs of 53.08 W m−2 (pH 4), 190.52 W m−2 (low‐grade heat), and 258.81 ...

Reprogrammable Phase‐Transition Composites for Adaptive Dynamic Shape Morphing

Advanced Science, EarlyView.
This paper reports a bio‐inspired reprogrammable phase‐transition composites that uses the stiffness change induced by reversible solid‐liquid phase transition to program and regulate the material deformation actuated by reversible liquid‐vapor phase transition, thereby achieving adaptive dynamic deformation in a controllable manner, and enabling ...

Vapor‐Assisted Catalysis Enables Precise Construction of MOF‐Derived Hierarchical Carbon Nanoarrays for High‐Performance Supercapacitors

Advanced Science, EarlyView.
A remote‐control strategy for catalyst design is unveiled for advanced carbon materials. During pyrolysis, zinc vapor from a physically separate source guides cobalt catalysts to construct a hierarchical carbon nanoarray. This approach prevents structural collapse while directing the dense growth of carbon nanotubes, yielding a material with ...

Dual Effect of Steric Hindrance in Non‐Aqueous Amine Absorbents: Navigating the Trade‐Off Between Kinetics and Thermodynamics for Efficient CO2 Capture

Advanced Science, EarlyView.
This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.
