Facile Manufacturing of PEEK‐Based Nanocomposites for High‐Efficiency Wide‐Temperature‐Range Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Herein, thermally robust poly(ether ether ketone)‐based composites reinforced by a hierarchical Fe3O4/carbon nanotubes/reduced graphene oxide (Fe3O4/CNTs/rGO) network are reported, delivering wide‐temperature‐range broadband electromagnetic wave absorption (298–573 K; minimum reflection loss (RLmin) ≈ −66 dB).

Closest‐Packed Pixel Structure Preparation and Driving Optimization for Electrowetting Displays

open access: yesAdvanced Electronic Materials, EarlyView.
This paper pioneers the preparation of hexagonal‐pixel Electrowetting Displays (EWDs) based on dense tiling principles. Compared to square pixels, they reduce the threshold voltage by 42.67% and the voltage required for maximum aperture ratio by 13.94%.

Dissecting Extreme Price Fluctuations in Mineral Fertilizers: Regularities and Co‐Movements in Light of Global Food Security

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Extreme swings in food prices can put food security at risk. Fertilizer prices are among the main drivers of food prices. This work explores the recurrent behavior of the extreme global fertilizer price fluctuations underlying food price dynamics.
