Degradation Mechanisms in PEM Water Electrolysis: Diagnosis and Impact

Advanced Materials Technologies, Volume 11, Issue 11, 5 June 2026.
This review provides an analysis of degradation mechanisms in proton electrolyte membrane water electrolyzers (PEMWE), focusing on all key components. It discusses diagnostic and measurement techniques for evaluating degradation, less‐studied mechanisms, and an expert survey.

INFLUENCE OF WELDING PARAMETERS ON WELD BEAD GEOMETRY IN LASER BEAM WELDING OF CARBON STEEL ST 37

Nonconventional Technologies Review
Laser beam welding (LBW) is a non-conventional joining technology widely used in industry due to its advantages, such as a small heat-affected zone (HAZ) and high precision.

Additive Manufacturing of Ni‐Based Thermoelectric Materials for Waste Heat Recovery

Advanced Materials Technologies, Volume 11, Issue 12, 18 June 2026.
Thermoelectric generators convert waste heat into electricity but are constrained by conventional fabrication. Here, laser powder bed fusion enables direct printing of customised n‐type Cu60Ni40 and p‐type Ni90Cr10 legs. The assembled module achieves 0.8% efficiency at ΔT = 419 K, demonstrating scalable additive manufacturing of eco‐friendly, design ...

Weld Pool Control in Laser Welding

, 2002
The objective of this work is the design of a feedback control system for the laser welding process, which is able to control the penetration depth of the weld. Firstly the possibilities to control the penetration depth of a weld when only partial penetration is demanded, for instance in the case of overlap configurations, will be discussed ...

Mild Focal Cooling Decouples Dendrites to Reconfigure Cortical Output

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Mild cooling of the cortical surface selectively modulates apical dendritic excitability, plasticity, and somato‐dendritic coupling, while uncoupling these effects from basal dendrites, and reshapes apical‐driven responses in barrel cortex during whisker touch.
