Spatially Regulated Gas Flow Control for Batch‐Drying of Large Area Slot‐Die‐Coated Perovskite Thin Films

Advanced Energy Materials, EarlyView.
Innovations are crucial for transferring high power conversion efficiencies (PCEs) to large‐scale perovskite devices. Here, a 2D regulated gas flow control for batch‐drying of slot‐die‐coated perovskite films is introduced. This drying method achieves homogeneous, pinhole‐free large‐area perovskite/silicon tandem solar cells and perovskite solar ...

Stringency and dissimilarity of Maximum Residue Levels affect bilateral agri‐food trade stability

Applied Economic Perspectives and Policy, EarlyView.
Abstract Food standards are rising in both prevalence and stringency. They protect consumers and may enhance demand stability but also pose compliance challenges to producers, with ambiguous effects on the stability of trade relationships. We analyze the impact of importers' Maximum Residue Levels (MRLs) along with bilateral MRL dissimilarity between ...

The effects of extreme weather on rural transportation infrastructure and crop prices along the Lower Mississippi River

Applied Economic Perspectives and Policy, EarlyView.
Abstract Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices.

Dynamic changes in the structure and concentration of the international grain and oilseed trading industry

Applied Economic Perspectives and Policy, EarlyView.
Abstract This paper aims to describe the evolution of firm and industry strategies and to analyze detailed transaction data on the structure of the international grain trading industry. Specifically, data are developed from vessel nominations, and these were used to derive measures of concentration and determine how these change across selected ...
