Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

Advanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

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.

King and Cochrane: The technological treadmill and racial inequity in US agriculture

Applied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.
