Highly Active IrRuOx/MnOx Electrocatalysts with Ultralow Anode PGM Demand in Proton Exchange Membrane Electrolyzers

open access: yesAdvanced Energy Materials, EarlyView.
MnOx‐supported IrRuOx exhibits outstanding OER performance in both liquid electrolytes and real cell environments. The MnOx not only enhances the dispersion of IrRuOx but also induces a compressive strain effect. The incorporation of Ru leads to surface reconstruction.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Layer‐by‐Layer Processed Pseudo‐Bilayer Heterojunctions Advance the Performance of Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Layer‐by‐layer processed pseudo‐bilayer heterojunctions offer flexible processing strategies, optimized morphology, enhanced efficiency and stability, and scaling potential for organic solar cells. Abstract Recent progress in organic (semiconductor) solar cells (OSCs) has led to power conversion efficiencies (PCEs) reaching 20%, with predictions that ...

The impact of HPAI trade restrictions on U.S. poultry exports in 2022–23

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract In early 2022, APHIS confirmed a case of highly pathogenic avian influenza (HPAI), signaling the beginning of an extensive HPAI outbreak. Since the start of the outbreak in 2022, more than 105 million birds across commercial and backyard operations in 48 states have been affected. Many countries, including top importers of U.S.
