Thin Reinforced Sulfonated Poly(phenylene sulfone) Membranes for Durable Water Electrolysis: Suppressed Swelling and Enhanced Stability Over 2000 Hours

Advanced Energy Materials, EarlyView.
Hydrocarbon membranes have the potential to significantly enhance the efficiency of water electrolyzers. However, their application is often limited by insufficient stability resulting from excessive swelling. This work presents a strategy to achieve efficient, safe and stable operation of a 24 µm thin hydrocarbon membrane by combining a modified ...

Temperature and Farm Labor in Nigeria

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Electric and Temperature Field‐Modulated Periodic Repair of the Electrode/Electrolyte Interface toward Long Cycle Stability of Low‐Temperature Li‐Ion Batteries

Advanced Energy and Sustainability Research, EarlyView.
This study introduces a temperature‐electric field synergy strategy to enhance lithium‐ion battery performance at low temperatures. It reveals interfacial mechanisms: low temperatures cause deterioration, while room temperature aids stable interphase formation.

Poly(Vinylidene Fluoride)‐Wrapped LiFePO4 Microspheres as Highly Stable Dual Functional Cathode for Solid‐State Lithium Batteries

Advanced Energy and Sustainability Research, EarlyView.
A dual functional cathode is made by uniformly dispersing the cathode material (LiFePO4) into the polymer electrolyte poly(vinylidenfluorid‐co‐hexafluorpropylene):lithium bis(trifluoromethanesulfonyl)imide, resulting in a conformable lamella structure with embedded microspheres.
