Alloy Solutions for Ammonia Cracking: A Review

open access: yesMaterials and Corrosion, Volume 77, Issue 6, Page 923-934, June 2026.
This work provides a literature overview of the nitriding and degradation of structural materials under ammonia cracking conditions and explains the known mechanisms and the gaps, where research is required. ABSTRACT Hydrogen is a key factor in energy storage and transportation, which will inevitably lead to a substantial increase in demand.

Laser Sintering and Optical Characterization of LuAG: Ce Ceramics

open access: yesphysica status solidi (b), Volume 263, Issue 6, June 2026.
Additive‐free densification of LuAG:Ce ceramics is achieved via CO2 laser sintering within seconds, producing high‐density and homogeneous microstructures compared to conventional processing. However, laser‐sintered samples exhibit enhanced oxygen vacancy concentrations, leading to reduced photoluminescence intensity and a red shift in emission.

Tuning Y‐Mg Supports for Improved Ni‐Catalyzed NH3 Decomposition: Structural Modulation and Mechanistic Insights

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Catalytic NH3 decomposition has garnered substantial attention for hydrogen transformation and storage. Ni‐based catalysts continue to suffer from limited thermal stability and suboptimal low‐temperature activity, largely attributed to an incomplete understanding of the structure‐activity relationships and reaction mechanisms governing their ...
