Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

open access: yesAdvanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

Selective Laser Sintering 3D Printing of Drug‐Loaded Intravitreal Implants

open access: yesAdvanced Functional Materials, EarlyView.
Selective laser sintering enables the fabrication of biodegradable and biocompatible intravitreal implants with tunable microstructures for sustained drug delivery. By modulating laser scanning speed, the polymer matrix architecture is engineered to control the release kinetics of dexamethasone and riboflavin over several months. This approach offers a

Entering the Strong Coupling Regime in Conventional Organic Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Organic solar cells convert light into fossil‐free energy, yet they still cannot compete with their silicon counterparts. Strong exciton‐photon coupling can ameliorate some properties of organic solar cells, but it requires additional mirrors that diminish light absorbance. Here, mirror‐free strong exciton‐photon coupling is implemented in conventional

Mechanically Tunable Bone Scaffolds: In Vivo Hardening of 3D‐Printed Calcium Phosphate/Polycaprolactone Inks

open access: yesAdvanced Functional Materials, EarlyView.
A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.
