All‐Electric Mimicking of Synaptic Plasticity Based on the Noncollinear Antiferromagnetic Device
Advanced Electronic Materials, EarlyView.Mn3Pt was chosen as spin source with a simple face‐centered cubic structure and a noncollinear antiferromagnetic configuration to build a spin‐orbit torque (SOT) device that mimics all‐electric synaptic behavior for developing neuromorphic computing.

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

Advanced Energy Materials, EarlyView.The study explores degradation of high‐nickel NCM cathodes during prolonged high‐voltage holds, revealing a novel non‐linear increase in charge transfer resistance (RCT) due to an inhomogeneous, resistive surface reconstruction layer (SRL). Detailed analyses uncover the gradual growth and non‐uniformity of the SRL, which causes constriction effects ...

Discerning Performance Bottlenecks of State‐of‐the‐Art Narrow Bandgap Organic Solar Cells
Advanced Energy Materials, EarlyView.This work quantitatively discerns the loss mechanisms of state‐of‐the‐art low‐bandgap organic solar cells based on BTPV‐4X‐eC9 acceptors. Compared to PM6:Y6, geminate recombination of charge transfer (CT) states governs photocurrent losses. This relates to conformational freedom of these acceptors that restricts their aggregation, and also counteracts ...

Applied Economic Perspectives and Policy, EarlyView.Abstract In this paper, we examine the impact of reducing Supplemental Nutrition Assistance Program (SNAP) benefits on grocery purchases using data from Circana. We use an imputed difference‐in‐difference model to exploit state‐level variation in decisions to remove pandemic‐era SNAP emergency allotments to estimate the impact of such policies. We find

On the Method of Brackets: Rules, Examples, Interpretations and Modifications
, 2015 The method of brackets, consisting of a small number of heuristic rules, was created by Ivan Gonzalez for the evaluation of definite integrals appearing in the resolution of Feynman diagrams. The current work verifies each step of this method, proves the independence on different representations of the integrand, and also modifies the rule by further ...

Advanced Energy and Sustainability Research, EarlyView.The synthesis of platinumcarbon aerogel electrocatalysts with multiscale porosity derived from biopolymer aerogels via supercritical deposition is presented. The electrocatalysts demonstrate similar overpotentials to commercial alternatives with significantly higher platinum loadings, while exhibiting superior stability due to enhanced porosity ...
