Effect of Metal Carbides on Hydrogen Embrittlement: A Density Functional Theory Study

Hydrogen
This study uses plane wave density functional theory (DFT) to investigate the effect of certain metal carbides (Niobium carbide, Vanadium carbide, Titanium carbide, and Manganese sulfide) on hydrogen embrittlement in pipeline steels.

Engineering thoughts on Hydrogen Embrittlement

Procedia Structural Integrity, 2018
Abstract Hydrogen Embrittlement (HE) is a topical issue for pipelines transporting sour products. Engineers need a simple and effective approach in materials selection at design stage. In other words, they must know if a material is susceptible to cracking, to be able of: selecting the right material and apply correct operational measures ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Reversible Phase‐Change‐Induced Transparency Switching and Dynamic Thermal Regulation Gel for Energy‐Efficient Smart Windows

EcoEnergy, EarlyView.
The phase transition process imparts shape‐stable gels with the capability of reversible transparency modulation and temperature‐responsive heat storage and release. When applied to smart windows, this property ensures the maintenance of thermal energy within the human thermal comfort zone, thereby facilitating indoor energy conservation.
