Orientation Control in Epitaxial PdO Thin Films Grown on MgO (001) – Role of Oxygen Chemical Potential

Advanced Materials Interfaces, Volume 12, Issue 18, September 22, 2025.
Crystal orientation of thin films is closely linked to their strain states, electronic properties, and surface chemical reactivity of functional materials. Therefore, understanding the mechanisms that govern orientation control is essential for materials design and synthesis.

Degradation of Abandonment Cement Plugs Under Prolonged Exposure to Completion Fluids: A Multi‐Technique Evaluation

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
Cement plugs used in oil well abandonment may degrade over time when exposed to completion fluids. This study shows a significant loss of compressive strength after 180 days, along with mineralogical changes like hydrocalumite formation. These findings highlight the importance of long‐term monitoring to ensure the safety and integrity of permanently ...

Influence of additives on the hydration, pore chemistry and phase assemblage of ferrite-rich steel slag-based cement clinker

Case Studies in Construction Materials
Electric arc furnace slag (EAFs) was used as an alternative material for alite-ferrite (C3S-C4AF) clinker synthesis. Successful synthesis achieved 26 wt% and 70 wt% of C4AF and C3S, that was used for hydration investigation.
