Light‐Induced Phase Segregation in Mixed‐Halide Perovskites: Reconciling Mechanistic and Thermodynamic Models

open access: yesAdvanced Energy Materials, EarlyView.
Light‐induced halide segregation limits the stability of mixed‐halide perovskites. This perspective shows how different mechanistic models can be viewed within a common free‐energy framework. It highlights the need to separate kinetic and thermodynamic aspects, the need for bulk‐sensitive measurements, and the need for controlled conditions to identify

Competing Charge Separation Pathways Govern Charge Generation in Organic Photovoltaic Blends: Insights From Transient Electron Spin Resonance

open access: yesAdvanced Energy Materials, EarlyView.
Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...

3D Printed Ordered Porous Architectures of Functional Metal Tellurides for Ultra High Mass‐Loaded Ammonium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) are emerging as promising alternatives for next‐generation energy storage. To overcome the limited ion diffusion associated with ultrahigh mass‐loading electrodes, this work develops a 3D‐printed porous conductive electrode of metal‐telluride fabricated via selective laser melting technique.

Water‐Mediated Proton Facilitation for Stable Acidic CO2 Electrocatalysis

open access: yesAdvanced Energy Materials, EarlyView.
Proton‐mitigating Cu─O─Ce sites accelerate *CO formation and PCET‐mediated *CO─*CHO coupling, enabling efficient multicarbon production at relatively low current density. Maintaining a retentive acidic pH suppresses parasitic hydrogen evolution and preserves in situ CO2 availability for carbon‐efficient acidic CO2 reduction.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...
