Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Development of a Two‐Stage Cold Pressing and Tempering Process of Graphite Compound Bipolar Plates
ABSTRACT Proton‐exchange membrane fuel cells (PEMFCs) are considered a key technology for decarbonized energy systems, particularly in combination with sustainably sourced green hydrogen. The functional performance and reliability of core components, such as bipolar plates (BPPs), depends critically on the manufacturing processes. This study explores a
