Cold Gas Sprayed Titanium Coating for Corrosion Protection of Bipolar Plates in Proton Exchange Membrane Water Electrolysis

Materials and Corrosion, EarlyView.
Climate‐neutral green hydrogen is produced via water electrolysis using renewable energy. This study explores using cold gas spraying to apply titanium coatings on steel bipolar plates for proton exchange membrane water electrolyzers. The coating shows effective corrosion protection, presenting a promising solution for future designs.

Hydrogen‐Enhanced Stress Corrosion Cracking of Wire Arc Additive Manufactured Inconel 625 Superalloy in NaCl Solution: Mechanism of Synergistic Degradation

Materials and Corrosion, EarlyView.
Hydrogen‐enhanced SCC of WAAM Inconel 625 in 3.5 wt.% NaCl solution. Hydrogen charging reduces passive film stability (lower corrosion potential) and promotes pitting at Laves phase/matrix interfaces. Stress corrosion cracks propagate along Laves‐rich regions, leading to quasi‐cleavage brittle fracture.

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

What If Cooking Isn't Chemistry? Examining the Good and the Harm in Metaphorical Connections Between Science and Everyday Activities

Science Education, EarlyView.
ABSTRACT This theoretical paper examines why we make claims like “cooking is chemistry,” what these claims mean, and what good or harm they accomplish. We make three interrelated arguments: First, the relationship between scientific and everyday practices is more complicated and less obvious than is often claimed; second, educators and scientists link ...
