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.

Magnetic Water Cleaning of Estrogens via Tight yet Dynamic Binding to Nanoparticles

Advanced Science, EarlyView.
Micropollution is one of the big challenges humanity faces with estrogen hormones being emerging pollutants of concern. Here, a supramolecular design strategy is presented that generates a simple nano‐adsorbent material to magnetically remove low‐concentrated estrogens from water.
