Activating Hidden Magnons With Anomalous Rotational Symmetry

open access: yesAdvanced Science, EarlyView.
Unlocking high‐frequency magnons hidden by symmetry constraints is crucial for terahertz technologies. This work demonstrates that breaking local mirror symmetry via Mn‐substitution in the paradigmatic spin–orbit–coupled Mott insulator Ca2${\rm Ca}_2$RuO4${\rm RuO}_4$ activates previously inaccessible mixed‐parity magnons.

The Impact of Cobalt Substitution on the Electrochemical Properties of Cubic Li6.6La3Zr1.6Ta0.4O12 Solid Electrolyte for All‐Solid‐State Li‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Cobalt is incorporated more readily into garnet Li6.6La3Zr1.6Ta0.4O12 when sintered in argon than in air. Under argon, Co in the garnet lattice lowers the total conductivity three‐ to fourfold; in air, Co segregates as LiCoO2 and raises the electronic conductivity about 100‐fold instead.

Localized Hydrogen Release Driven by Mg–Pd Microgalvanic Cells from 3D‐Printed Microneedles Reverses Redox Homeostasis for Psoriasis Treatment

open access: yesAdvanced Science, EarlyView.
A 3D printing microneedle (MP‐MN), loading magnesium‐based micro‐galvanic cells (MP), is designed for improving psoriasis. H2 generated from MP‐MN scavenges ROS and •OH, actives NRF2‐KEAP1 pathway, and decreases inflammation, thereby effectively restoring the oxidative stress homeostasis of psoriatic skin and suppressing the excessive proliferation of ...
