Adsorption and interfacial phenomena of a Lennard-Jones fluid adsorbed in slit pores: DFT and GCMC simulations
Míguez Díaz, José Manuel; Gómez Álvarez, Paula; Martínez Piñeiro, Manuel; Mendiboure, Bruno; Jiménez Blas, Felipe(Taylor and Francis, 2018)
Confinement of fluids in porous media leads to the presence of solid–fluid (SF) interfaces that play a key role in many different fields. The experimental characterisation of SF interfacial properties, in par- ticular the ... -

Computational study of the interplay between intermolecular interactions and CO2 orientations in type I hydrates
Pérez Rodríguez, Martín; Vidal Vidal, Ángel; Míguez Díaz, José Manuel; Jiménez Blas, Felipe; Torré, Jean-Philippe (Royal Society of Chemistry, 2017)
Carbon dioxide (CO2) molecules show a rich orientation landscape when they are enclathrated in type I hydrates. Previous studies have described experimentally their preferential orientations, and some theoretical works ... -
Equilibrio de fases y propiedades interfaciales de sistemas moleculares de interés industrial
Feria Delgado, Esther (Universidad de Huelva, 2022)Desde finales del siglo XX ha crecido el interés por el estudio del biodiesel como alternativa a los combustibles fósiles y como una forma de reducir la emisión de gases de efecto invernadero. Esto es debido a que el ... -
Influence of the long-range corrections on the interfacial properties of molecular models using Monte Carlo simulation
Míguez Díaz, José Manuel; Martínez Piñeiro, Manuel; Jiménez Blas, Felipe(AIP Publishing, 2013)
We analyze the influence of the long-range corrections, due to the dispersive term of the intermolecular potential energy, on the surface tension using direct simulation of the vapour-liquid interface of different molecular ... -
Molecular dynamics simulation of CO2 hydrates: Prediction of three phase coexistence line
