Unveiling a Near‐Total Rear Passivation for High Performance of Ultra‐Thin ACIGS
Ultra‐thin solar cells of (Ag,Cu)(In,Ga)Se2 (ACIGS) suffer from rear interface recombination, limiting their performance. To tackle it, a full coverage plasma enhanced chemically vapor‐deposited 8 nm porous SiOx passivation layer was implemented and evaluated. It is shown that a combination of the near‐complete passivation from silica and the formation

Cavity‐Enhanced Eye‐Readable Detection of 0.1% H2 via Active Modulation of Charge‐Transfer Plasmons
A cavity‐structured nanoparticle sensor is developed for highly sensitive, eye‐readable hydrogen detection. Its excellent colorimetric response arises from a hydrogen‐induced charge‐transfer mechanism: reduction of the dielectric oxide shell in H2 triggers a transition from the plasmonic gap mode to the charge‐transfer plasmon mode.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials
This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of
