Dynamics of Surfactant Clustering at Interfaces and Its Influence on the Interfacial Tension: Atomistic Simulation of a Sodium Hexadecane-Benzene Sulfonate-Tetradecane-Water System
Paredes, Ricardo; Fariñas Sánchez, Ana Isabe; Medina Rodrĺguez, Bryan; Samaniego, Samantha; Aray, Yosslen; Álvarez, Luis Javier (2018)The process of equilibration of the tetradecane-water interface in the presence of sodium hexadecane-benzene sulfonate is studied using intensive atomistic molecular dynamics simulations. Starting as an initial point with ... -
Exploring the effect of the O -(1-heptylnonyl) benzene sulfonate surfactant on the nature of the linear hydrocarbons/water interface by means of an atomistic molecular dynamics simulation
Aray, Yosslen; Parra, José Gregorio; Jiménez, Doris Marianela; Paredes, Ricardo; Matiz, Alejandro; Samaniego, Samantha (2017)Using molecular dynamics simulations a systematic study of the binding energy per cross sectional area for the water/n-alkane (hexane, octane, decane, dodecane and tetradecane) interfaces was performed. The effect of the ... -
Exploring the nature of the interactions between the molecules of the sodium dodecyl sulfate and water in crystal phases and in the water/vacuum interface
Aray, Yosslen R.; Parra, José G.; Paredes, Ricardo; Álvarez, Luis Javier; Díaz Barrios, Antonio (2020)The nature of the interaction between the molecules of the sodium dodecyl sulfate surfactant forming two crystal phases, one anhydrous, NaC12H25O4S and the other, NaC12H25O4S.H2O, hydrated with one water molecule for unit ... -
On the electron density localization in elemental cubic ceramic and FCC transition metals by means of a localized electrons detector
Aray, Yosslen; Paredes, Ricardo; Alvarez, Luis Javier; Martiz, Alejandro (2017)The electron density localization in insulator and semiconductor elemental cubic materials with diamond structure, carbon, silicon, germanium, and tin, and good metallic conductors with face centered cubic structure such ...
