Reflection on the horizontal and vertical organization of water at oxide interfaces and their SFG vibrational signatures

Key Points

• The research aims to investigate water organization on oxide interfaces at the molecular level and its impact on wettability.
• Examined wetting behaviors of SiO2 and Al2O3 surfaces under PZC conditions.
• Utilized graph theory to analyze molecular interactions.
• Assessed vibrational signatures to understand water organization.
• Hydrophobic characteristics were identified on the oxide surfaces.
• Wettability behaviors are closely linked to molecular-level interactions.
• Vibrational signatures provided insights into the molecular arrangement of water.
