Ultralow‐Frequency Epsilon‐Near‐Zero States in 3D‐Printed High‐Entropy Alloy Metacomposites for Ultra‐Thin Perfect RF Absorption

open access: yesAdvanced Materials, EarlyView.
Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...

Directed Functionalization of Recombinant Spider Silk Nonwoven Membranes with Antibodies Using Non‐Canonical Amino Acids

open access: yesAdvanced Materials, EarlyView.
A recombinant spider silk protein was functionalized by incorporating genetically encoded bio‐orthogonal reactive azido‐groups. The azido‐functionalized proteins were produced in a scalable biotechnological process, and particles, films, as well as nanofibers were established as anchorage for fully functional antibodies via site‐specific bio‐orthogonal

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
