Hydrogen Storage Materials and High-Entropy Alloys
This community focuses on the development of solid-state materials for storing hydrogen and the engineering of high-entropy alloys for structural applications. The work is driven by the need for safe, high-capacity energy storage media and robust metallic structures for demanding environments.
The research is dominated by the investigation of metal hydrides, particularly magnesium-based systems, for reversible hydrogen absorption and desorption. A significant portion of the work involves computational modeling, specifically density functional theory, to predict the stability and storage capacity of novel hydride compounds, including perovskite structures. Concurrently, the community studies high-entropy alloys, focusing on their microstructure, mechanical properties, and refractory characteristics. Recent efforts integrate machine learning to accelerate the discovery of new storage materials and optimize the kinetics of hydrogen sorption in nanostructured systems.
The largest share of the community's output is found in hydrogen research, accounting for 2.8% of all hydrogen studies, with 16,658 papers in this group. Carbon research contributes 3,802 papers, representing 0.4% of that element's total output, while magnesium research includes 2,031 papers, or 1.2% of its field.
The community comprises 24,476 papers, publishing most frequently in the International Journal of Hydrogen Energy, Journal of Alloys and Compounds, and The Journal of Physical Chemistry C.
Recent work continues to explore the interplay between alloy composition and hydrogen storage kinetics, with new studies examining AI-driven discovery of hydrides and the mechanical resilience of multi-principal element alloys under extreme conditions.
