Double Helix Structure for Stable Flexural Actuation in Soft Robotics
Advanced Intelligent Systems, EarlyView.This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

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

American 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.

Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation
Angewandte 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 ...
