Description

Application

• Molecular Dynamics in Surfactant Research: Dong et al. conducted molecular dynamics simulations to study the effects of surfactants on methane and n-decane interactions. This research provides insights into the applications of n-decane in enhancing the performance of surfactants in oil recovery and environmental remediation processes (Dong et al., 2024).
• Interfacial Adsorption Studies: Ruwoldt et al. explored the interfacial adsorption properties of oil-soluble kraft lignin and its ability to stabilize water-in-oil emulsions, where n-decane plays a crucial role as a model hydrocarbon solvent, contributing to understanding emulsion stability and lignin-solvent interactions in industrial applications (Ruwoldt et al., 2024).
• Semiconductor Strain Gauges in Geotechnical Engineering: Mikhaltsevitch and Lebedev utilized semiconductor strain gauges to measure the effective stress coefficient for the elastic moduli of sandstone. N-decane could potentially be used as a fluid medium in these experiments to simulate natural hydrocarbon environments, enhancing the accuracy of geophysical assessments (Mikhaltsevitch et al., 2024).
