Advanced Energy Materials, EarlyView.This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Quantifying the land‐use change due to soybean‐based biodiesel in the United States
Applied Economic Perspectives and Policy, EarlyView.Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...

Angewandte Chemie, EarlyView.A low‐density, nonfluorinated moderately solvating electrolyte (MSE) composed of methyl tert–butyl ether concurrently tunes Li+ and polysulfide solvation, lowering desolvation barrier and mitigating polysulfide shuttling. It effectively stabilizes both electrodes and enables stable cycling of Li–S batteries under practical parameters at room ...

Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Perennial bioenergy crops, such as miscanthus and switchgrass, and crop residues have the potential to scale up sustainable aviation fuel (SAF) production and mitigate carbon emissions. However, high establishment costs, delayed returns, and risk–return profiles that diverge from those of conventional crops can hinder incentives to adopt ...

Markets Mitigate Land‐Use Competition From Energy Crops and Increase Farm Revenues
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Meeting the US Sustainable Aviation Fuel Grand Challenge target of 35 billion gal annually by 2050 will require an estimated 380 million–700 million dry tons of agricultural biomass feedstock. This study evaluates the implications of large‐scale biomass production for land use, crop production, and market outcomes under mature market ...

Work of Breathing for Aviators: A Missing Link in Human Performance
LifeIn this study, we explore the work of breathing (WoB) experienced by aviators during the Anti-G Straining Maneuver (AGSM) to improve pilot safety and performance. Traditional airflow models of WoB fail to adequately distinguish between breathing rate and
