A Differential Alkaline Electrolysis Cell to Study Scaling Effects

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
What conclusions about the behavior of large electrolysis stacks can be drawn from small lab cell experiments? The concept of a differential electrolysis cell was developed in this work to answer this question. The cell allows for the setting of local operating conditions corresponding to specific positions inside an electrolyzer. This paves the way to

Direct Numerical Simulation of Magnetohydrodynamic Slip‐Flow Past a Stretching Surface Using Physics‐Informed Neural Network

open access: yesHeat Transfer, Volume 55, Issue 3, Page 1674-1682, May 2026.
ABSTRACT Traditional numerical methods, such as finite difference methods (FDM), finite element methods (FEM), and spectral methods, often face meshing challenges and high computational cost for solving nonlinear coupled differential equations. Machine learning techniques, specifically Physics‐informed machine learning, address these obstacles by ...

Determining Diffusion Coefficients in Polymer Electrolyte Membranes With Lab Based Micro X‐Ray Fluorescence Analysis: A Proof of Concept

open access: yesX-Ray Spectrometry, Volume 55, Issue 3, Page 465-472, May/June 2026.
ABSTRACT The diffusion of metal ions in polymer electrolyte membranes is an important parameter for aging and capacity loss in electrochemical cells. Here, the diffusion coefficients of vanadium ions in Nafion membranes are studied. These are important to describe transportation of the ions through the membrane separator in vanadium redox flow ...

Predicting Positive Affect in Infancy

open access: yesDevelopmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Positive affect (PA) is integral to health and development, yet its early origins remain largely unexplored. In this pre‐registered study (N = 78), we investigated whether infant‐specific biological and social‐behavioral factors predict PA in early development.

Techno‐Economic Analysis of a Three‐Compartment CO2 Electrolyzer for Formic Acid Production

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
The electrochemical conversion of CO2 to formic acid is a sustainable route for storing renewable energy. Operating three‐compartment electrolyzers at high product concentrations and high selectivity shows great promise for economic viability. Integrating green hydrogen production and CO2 from hard‐to‐abate industries further enhances the potential of ...
