Nucleation in the presence of an amphiphile: A density functional approach
Density functional theory is applied to the study of gas-to-liquid nucleation in binary and ternary mixtures with one amphiphilic component. The theory allows the evaluation of density profiles and molecular orientation distributions in the critical nucleus. The predicted cluster compositions for binary and ternary systems resemble qualitatively the experimental behavior for water–n-alcohol and...
متن کاملVolumetric properties of {n-butyl acetate + 1-butanol + 1,2- butanediol} at temperature between [298.15 ,303.15 and 308.15] K.
Densities and excess molar volume of the binary and ternary mixtures formed by nbutylacetate+ 1-butanol + 1,2-butanediol were measured at (298.15, 303.15, and 308.15) K forthe liquid region and at ambient pressure (81.5) k Pa , for the whole composition range. Theexcess molar volumes,VmE and excess partial molar volume ViE ,were calculated fromexperimental densities.The excess molar volumes are...
متن کاملMolecular dynamics simulation of nucleation in the binary mixture n-nonane/methane.
Vapor-liquid nucleation in the binary system n-nonane/methane is investigated by molecular dynamics simulation. The supersaturation is achieved by cooling down the system during the expansion in order to closely mimic the real process. Binary clusters formed by nucleation are frequently inhomogeneous objects in which components are not well mixed. By studying high-pressure nucleation and cluste...
متن کاملKinetic stability of complex molecular clusters.
This investigation is concerned with modeling the evaporation, or decay, of n-nonane molecular clusters. We use a unique cluster decay model that was first developed to estimate the decay time scale of argon clusters using molecular-dynamics simulations. In this study we seek to enhance the model so that it represents a more complex cluster decay dynamic, suitable for n-nonane clusters. Experim...
متن کاملExamination of Organic Vapor Adsorption onto Alkali Metal and Halide Atomic Ions by using Ion Mobility Mass Spectrometry
We utilize ion mobility mass spectrometry with an atmospheric pressure differential mobility analyzer coupled to a time-of-flight mass spectrometer (DMA-MS) to examine the formation of ion-vapor molecule complexes with seed ions of K+ , Rb+ , Cs+ , Br- , and I- exposed to n-butanol and n-nonane vapor under subsaturated conditions. Ion-vapor molecule complex formation is indicated by a shift in ...
