Thermal‐Ionic Coupling in Transpiration‐Inspired Janus Nanofiber Membranes: Synergistic Dry‐Wet Interface Engineering for Solar‐Driven Electricity Generation

Advanced Science, EarlyView.
A transpiration‐inspired Janus nanofiber membrane creates a persistent dry‐wet interface that couples localized solar heating with hydration‐induced ion regulation. The asymmetric architecture sustains directional water and ion transport, suppresses salt accumulation, and enables simultaneous seawater evaporation and stable electricity generation ...

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Dimensional Engineering of Carbon‐Based Hybrids: From 1D Conductive Networks to 3D Porous Architectures for Next‐Generation Microwave Absorption

Advanced Science, EarlyView.
This review explores dimensional architecture engineering to overcome the impedance‐attenuation trade‐off in electromagnetic wave absorbing materials. By analyzing 1D to 3D structures and their multidimensional hybrids, we highlight synergistic mechanisms for enhanced performance.

Light‐Controlled Conductive Molecular Wire in an Artificial Lipid Membrane

Advanced Science, EarlyView.
A photochromic azobenzene derivative is shown to produce a unique photoelectric response when embedded in artificial lipid membranes. In its trans state, it forms conductive “molecular wires” that enhance membrane conductivity in the dark. Light‐induced cis isomerization suppresses this effect, showing that short‐chain molecules can modulate membrane ...

A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

Advanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.
