Modulating Iridium Electronic Structure With High‐Valent Metal Doping for Efficient and Durable Acidic Oxygen Evolution Reaction

open access: yesAdvanced Functional Materials, EarlyView.
We synthesized a novel IrCuOx/MnO2 heterostructure co‐doped with high‐valent W and Mo atoms, achieving exceptional acidic stability and high mass activity. Owing to the synergistic effects of structural and electronic modulation, cooperative charge redistribution occurs across both the interface and the lattice.

Enhanced Li‐Ion Battery Performance with Hybrid MXene/GnR Electrodes: Heterojunctions and Engineered Architectures Supported by DFT Mechanistic Studies for Improved Rate Performance, Stability & Capacity

open access: yesAdvanced Functional Materials, EarlyView.
Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...

Speckle‐Engineered Upconversion Amplification in Nanoemulsion‐Templated Hydrogel Microdomes

open access: yesAdvanced Functional Materials, EarlyView.
Nanoemulsion‐confined PEGDA microdomes generate speckle‐like excitation fields that strongly amplify upconversion luminescence upon dehydration, enabling filter‐free visible readout with reversible on–off switching. DMD‐based lithography yields scalable, shape‐programmable arrays for moisture‐responsive displays and optical encryption.

The Monotonicity Puzzle. An Experimental Investigation of Incentives Structures [PDF]

open access: yes
Non–monotone incentive structures, which — according to theory — are able to induce optimal behavior, are often regarded as empirically less relevant for labor relationships.

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.
