Description

Application

• Kirkwood-Buff Analysis of Binary and Ternary Systems Consisting of Alcohols (Methanol, Ethanol, 1-Propanol, and 2-Propanol), Water, and n-Hexane to Understand the Formation of Surfactant-Free Microemulsions.: This research elucidates the molecular interactions in microemulsions involving 1-Propanol, offering insights into its use in creating stable, surfactant-free systems (Seo et al., 2024).
