Toward Energy‐Efficient Alkaline Water Electrolysis: Advances in Mass Transport Optimization and Electrolyzer Design

open access: yesAdvanced Energy Materials, EarlyView.
Component‐level engineering in alkaline water electrolysis (AWE) is systematically analyzed, highlighting strategies in porous electrodes, bubble management, membranes, and flow fields to overcome mass‐transport bottlenecks. By linking microstructural design to multi‐scale ionic and gas transport, this Review establishes design principles that connect ...

Row Crops and the U.S. Agricultural Trade Deficit: Recent Trends and Policy Issues

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Row crops such as soybeans, corn, wheat, and cotton are the backbone of the U.S. farm sector, accounting for around $60 billion of exports in 2023. While U.S. row crop exports remain robust, growing concerns over the rising U.S. agricultural trade deficit underscore the need to appraise the ongoing market and policy dynamics affecting the ...

MHD THREE-DIMENSIONAL STAGNATION-POINT FLOW OF A MICROPOLAR FLUID [PDF]

open access: yes, 2011
The steady three-dimensional stagnation-point flow of an electrically conducting micropolar fluid in the absence and in the presence of a uniform external electromagnetic field (E0,H0) is analyzed and some physical situations are examined. In particular,
