AI–Guided 4D Printing of Carnivorous Plants–Inspired Microneedles for Accelerated Wound Healing

open access: yesAdvanced Materials, EarlyView.
This work presents an artificial intelligence (AI)‐guided 4D‐printed microneedle platform inspired by carnivorous plants for wound healing. A thermo‐responsive shape memory polymer enables body temperature–triggered self‐coiling for autonomous wound closure.

Chiral Metal Halide Perovskites for Spin‐Polarized Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
Chiral metal–halide perovskites offer a route to circularly polarized light without external polarizers. This Perspective compares two spin‐light emitting diode concepts: intrinsically chiral emissive layers and chiral spin‐filter interlayers that inject spin‐polarized carriers into efficient achiral emitters.

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

open access: yesAdvanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Phase Diagrams Enable Solid‐State Battery Design

open access: yesAdvanced Materials Interfaces, EarlyView.
Batteries are non‐equilibrium devices with inherent thermodynamic driving forces to react at interfaces, regardless of kinetics or operating conditions. Chemical potential mismatches across interfaces are dissipated via interfacial reactions. In this work, it is illustrated how phase diagrams and chemical potential maps predict degradation pathways but

Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

open access: yesAdvanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.
