Decoupling Membrane Electrode Assembly Materials Complexity from Fuel Cell Performance through Image‐Based Multiphase and Multiphysics Modelling

Advanced Energy Materials, Volume 15, Issue 27, July 15, 2025.
A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

Physics‐informed neural networks (PINNs) for high‐resolutional prediction of shear stress on cells in suspension culture

AIChE Journal, Volume 71, Issue 7, July 2025.
Abstract The effect of shear stress on cell behaviors should be considered for designing the suspension culture of mammalian cells. Computational flow dynamics (CFD) is a promising tool for estimating shear stress on cells, but the accuracy is limited due to resolution limitations.

SDF‐Guided Point Cloud Generation Framework for Mesh‐Free CFD

International Journal for Numerical Methods in Fluids, Volume 97, Issue 7, Page 1035-1056, July 2025.
This paper presents different methods for generating clouds of points around objects for use with meshless methods in computational fluid dynamics. This image shows the cloud generated around the original ROBIN body. ABSTRACT Meshing is a bottleneck of CFD workflows, especially when complex geometries are considered.

Numerical Investigations of the Aerothermal Performance of Modern Turbine Blade Tip Geometries at Design and Off‐Design Conditions and Under Stationary and Moving Shroud

Heat Transfer, Volume 54, Issue 5, Page 3193-3207, July 2025.
ABSTRACT High‐pressure turbine blade tips operate under extreme thermal stress, generating significant aerodynamic losses that must be continually optimized to improve engine efficiency and durability. This study uses computational fluid dynamics (CFD) to investigate the aerodynamic and thermal behavior of advanced turbine blade tip configurations ...

Production of hydroxyectoine from biogas by an engineered strain of Methylomicrobium alcaliphilum using a novel Taylor‐flow bioreactor

Journal of Chemical Technology &Biotechnology, Volume 100, Issue 7, Page 1425-1433, July 2025.
Abstract BACKGROUND The production of compatible solutes, such as ectoine and hydroxyectoine, is of great interest due to their industrial and biotechnological applications. Methylomicrobium alcaliphilum was genetically engineered to replace a native gene with a heterologous one, aiming to enhance ectoine production.

Existence of a local strong solution to the beam–polymeric fluid interaction system

Mathematische Nachrichten, Volume 298, Issue 7, Page 2327-2379, July 2025.
Abstract We construct a unique local strong solution to the finitely extensible nonlinear elastic (FENE) dumbbell model of Warner‐type for an incompressible polymer fluid (described by the Navier–Stokes–Fokker–Planck equations) interacting with a flexible elastic shell.
