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 ...

Light‐Induced Phase Segregation in Mixed‐Halide Perovskites: Reconciling Mechanistic and Thermodynamic Models

open access: yesAdvanced Energy Materials, EarlyView.
Light‐induced halide segregation limits the stability of mixed‐halide perovskites. This perspective shows how different mechanistic models can be viewed within a common free‐energy framework. It highlights the need to separate kinetic and thermodynamic aspects, the need for bulk‐sensitive measurements, and the need for controlled conditions to identify

Unlocking Three‐Dimensional Electron and Ion Transport in High‐Loading and Dense Lithium‐Ion Battery Electrodes Assisted via Porous Graphene Networks

open access: yesAdvanced Energy Materials, EarlyView.
Graphene mesosponge (GMS) enables three‐dimensional electron and ion transport in high‐loading, densely packed lithium‐ion‐battery electrodes through its unique mesoporous structure. The three‐dimensionally interconnected carbon network and electrolyte retained within the GMS mesopores ensure efficient electronic and ionic conduction, respectively ...

Differentiated Impacts of EU Rural Development Measures: A Finite Mixture Evaluation of Italian Olive Farms

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper examines the relationship between participation in the EU Rural Development Program and the economic performance of Italian olive farms using a finite‐mixture model with inverse‐probability‐weighted regression adjustment. Based on 2010–2022 FADN panel data, it estimates heterogeneous treatment effects while correcting for selection ...

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

open access: yesAgribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Price Transmission and Leadership in the Global Poultry Market: Results From Parametric and Nonparametric Approaches

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil and the United States account for more than 40% of global poultry exports, with China and South Korea among their major destination markets. This study examines price transmission and market linkages between Brazil and the United States using monthly poultry export price data from January 1990 to December 2024. It also assesses which of
