Multifunctional Matrix‐Activated Electrodes Enabling Efficient Proton Transport and Durable Low‐Pt Operation for High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesAdvanced Energy Materials, EarlyView.
This work introduces a CeHP‐enabled multifunctional matrix‐activated electrode (MME) for high‐temperature PEM fuel cells, forming an electrochemically and mechanically functional matrix within the catalyst layer. The design increases peak power density by 38% and reduces voltage decay by 62% at 240 °C, while using only 40% of the Pt loading of a ...

Surface‐Engineered Ti3C2Tx MXene/Cu2O Photocathodes for Highly Selective Photoelectrocatalytic CO2 Reduction to Ethanol

open access: yesAdvanced Energy Materials, EarlyView.
Surface‐engineering Ti3C2Tx MXenes with an in situ‐grown TiO2 layer on the surface in combination with visible‐light‐absorbing Cu2O significantly enhances charge separation and carrier extraction while improving Cu2O resistance to photocorrosion. The resulting Cu2O/TiO2‐MXene photocathodes enable highly selective, solar‐driven ethanol production ...

Consumers' Willingness to Pay a Premium for Climate‐Friendly Food Production: The Role of Production Method Information and Social Norms

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines whether information about production methods and social norms can increase consumers' willingness to pay (WTP) a price premium for food produced using climate‐friendly farming methods. A randomized survey experiment was conducted with 1568 respondents across Denmark, Lithuania, and Spain, who were assigned to one of four ...

Pulsed corona-induced CO2 methanation

open access: yes, 2015
CO2 methanation has been observed by application of pulsed corona discharges in a CO2 atmosphere over a deionized water film. At 46 kJ/L energy density, approximately 440 ppm CH4 has been observed at a production efficiency near 398 pmol/J.

Alternative Policy Designs to Help Farmers Select Profitable Conservation Practices

open access: yesAgribusiness, EarlyView.
ABSTRACT Voluntary private carbon initiatives (VPCIs) promote the implementation of agricultural conservation practices that mitigate emissions of greenhouse gases (GHGs) via financial incentives to participating farmers. Simultaneously, an array of public policies supports the adoption of conservation practices through technical and financial ...

Hole‐Activated Lattice Oxygen Enables Pt‐Free Propane Dehydrogenation by Eliminating the Hydrogen Recombination Bottleneck

open access: yesAngewandte Chemie, EarlyView.
Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...

Does Participating in Agricultural Global Value Chains Promote Agricultural Growth?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines the relationship between GVC participation and agricultural value‐added growth in 43 countries over the period 1995–2022. In contrast to prior literature, we disaggregate the agricultural sector into four sub‐sectors namely crop cultivation, animal production, forestry and fishing.

Modeling Syngas Composition in an Integrated System of Biomass Gasification, Electrolysis and Methanation

open access: yes
Composition of biogenous syngas can be improved by integration of electrolysis powered by irregular energy sources, and methanation. A mathematical model has been developed that helps analyzing the mixing and methanation processes of syngas with excess ...

Breakthrough Design of Highly Potent Antivirals Against Wild‐Type HIV‐1 and Lenacapavir‐Resistant M66I Variant

open access: yesAngewandte Chemie, EarlyView.
Lenacapavir, the first‐in‐class drug targeting HIV‐1 capsid, is a breakthrough drug in HIV‐1 treatment and prophylaxis. However, a single M66I mutation confers complete viral resistance to lenacapavir. We report herein the design and synthesis of innovative R2 analogs demonstrating low nM potency against HIV‐1 M66I and excellent pharmacokinetics in ...
