• “Thermal and mechanical properties of Mg–Al–Si–O–N glasses with up to 6.2 at.% nitrogen”
  Authors: Theany To, et al.
  Journal: Journal of the American Ceramic Society, 2025.
  Summary: This study investigates the thermal and mechanical properties of magnesium-aluminum-silicon oxynitride (Mg–Al–Si–O–N) glasses containing up to 6.2 atomic percent nitrogen. The research aims to understand how nitrogen incorporation influences the structure and properties of these glasses. While the specific details of this study are not available in the provided sources, related research has shown that increasing aluminum content in similar glass systems leads to higher glass transition and crystallization temperatures, as well as increased viscosity. These changes are attributed to the progressive polymerization of the silicate network due to the glass-forming role of Al₂O₃. ​mostwiedzy.pl+1KFUPM+1KFUPM+1mostwiedzy.pl+1

• “Fracture behavior of brittle particulate composites”
  Authors: T. Lacondemine, Theany To, et al.
  Journal: Materialia, 2024.
  Summary: This paper examines the fracture behavior of brittle matrix composites containing particulate reinforcements. Although specific details are not available, earlier studies have explored similar systems. For instance, research on glass matrices with nickel spheres investigated how the inclusion of metal particles affects fracture energy and crack propagation. The findings indicated that the presence of these particles can lead to local crack blunting, thereby increasing the material’s fracture energy. ​SpringerLinkSpringerLinkSpringerLink
