Simulation‐Based Design and Evaluation of an Alkaline Direct Glycerol Fuel Cell Stack With Integrated Purification

Fuel Cells, Volume 26, Issue 4, August 2026.
ABSTRACT Direct glycerol fuel cells (DGFCs) are a promising technology, but scaling them remains a challenge due to persistent technological and economic limitations. In this context, process simulation and modeling emerge as crucial tools. This study addresses the implementation of a conventional alkaline DGFC stack model in Aspen Plus and proposes a ...

Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

Journal of Plant Nutrition and Soil Science, Volume 189, Issue 4, Page 558-570, August 2026.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Impact of Climate Change on the Potential Distribution of Macaúba (Acrocomia aculeata, Acrocomia totai, Acrocomia intumescens) in Brazil

GCB Bioenergy, Volume 18, Issue 8, August 2026.
Climate change is projected to drive contrasting responses among Brazilian macaúba palms, ranging from relative stability and expansion to severe suitability loss. Ensemble ecological distribution models identified Acrocomia intumescens as highly vulnerable, while A.

Ensembling Crop Models and Multi Criteria Analysis to Unlock Bioenergy From Marginal Lands: A Scenario‐Based Assessment From Italy

GCB Bioenergy, Volume 18, Issue 8, August 2026.
Multi‐Criteria Analysis to identify marginal land on which three crops (Safflower, castor bean, and Ethiopian mustard) were simulated with two process‐based models (DSSAT, ARMOSA) under two different agronomical management minimums (rainfed and no fertilization) and low input (half‐water and half‐nitrogen).
