Advanced Functional Materials, EarlyView.An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

International Price Dispersion and the Direction of Trade [PDF]
The importance of trade costs in segmenting product markets cannot be captured by considering aggregate prices or in the absence of information on the direction of trade.

Advanced Functional Materials, EarlyView.A Zn2+‐coordinated poly(vinylidene fluoride) binder is shown to suppress Jahn–Teller‐driven Mn dissolution while improving dispersion, wettability, and structural integrity in thick MnO2 cathodes. This simple binder‐engineering strategy enables high‐loading aqueous Zn‐ion batteries with enhanced areal capacity, cycling stability, and practical promise ...

Advanced Healthcare Materials, EarlyView.We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

Deciphering the nexus of trade frictions, pollution, and export quality
Humanities & Social Sciences CommunicationsIn this study, we explore the intricate relationship between domestic trade costs, pollution emissions, and the quality of exports. Utilizing a decade of provincial data from China, we employ spatial econometric models to dissect the nexus among these ...

Advanced Healthcare Materials, EarlyView.Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

Advanced Healthcare Materials, EarlyView.This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

Measured Aggregate Gains from International Trade [PDF]
Do theoretical welfare gains from trade translate into aggregate measures of economic activity? We calculate the changes in real GDP and real consumption that result from changes in trade costs in a range of workhorse trade models, following the ...
