Boosting Charge Storage in Ferri/Ferrocyanide‐Based Alkaline Redox Flow Batteries

open access: yesAngewandte Chemie, EarlyView.
By modifying the solvation environment, cation engineering through Li+ substitution of traditional K+ or Na+ boosts the alkaline solubility of the ferri/ferrocyanide catholyte redox couple, providing a viable pathway to overcome the long‐standing challenge of energy density limitations for aqueous redox flow batteries (RBFs).

Fast, Strong Capillary Liquid Metal Muscles

open access: yesAdvanced Intelligent Systems, EarlyView.
Capillary liquid metal muscles (CLMMs) harness the exceptionally high and electrochemically tunable surface tension of gallium‐based liquid metals (e.g., EGaIn) to generate mechanical work. Confinement within microchannels maximizes surface‐energy conversion, enabling high force, ultrafast response (<25 ms), low‐voltage operation (<10 V), and ...

Farm labor scarcity and its uneven impacts on crop producers in the United States

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Evolutionary relationship between organellar DNA inheritance patterns and traits of seed plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise In plants, organellar DNA is predominantly maternally inherited, but biparental and paternal inheritance have also been observed. Specific mechanisms, such as plastid exclusion during pollen mitosis or genome degradation, ensure maternal inheritance.

Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation

open access: yesAngewandte Chemie International Edition, EarlyView.
We report a hierarchical poly(ionic liquid)–carbon nitride membrane supported on anodic alumina for efficient monovalent/divalent ion separation. Confined nanochannels and tailored interfacial ion interactions enable exceptional K+/Mg2+ ( > 500) and Li+/Mg2+ ( > 200) selectivities, offering a promising strategy for advanced aqueous ion separations ...
