Coverage-dependent molecular ejection from ion-bombarded C6H6/Ag{111}
Article Abstract:
The neutral benzene (C6H6) on Ag{111} was subjected to 8 kiloelectronvolt ion bombardment to investigate the time-of-flight (TOF) distributions, angular distributions and relative sputtering yields of the ejected C6H6 molecules. Two components were found to be present in the TOF distributions derived using Ag+ ion as the projectile. The C6H6 kinetic energy and angular distributions at low coverage were found to exhibit similar characteristics with the Ag particles ejecting from the substrate. The largest total yield of the ejected C6H6 molecules was observed for a monolayer coverage.

Soret coefficients of organic solutions measured in the microgravity SCM experiment and by the flow and Benard cells
Article Abstract:
The flow cell, Schmidt-Milverton plots and microgravity conditions were used to obtain measurements of the Soret coefficients of aqueous solutions of methyl, ethyl, isopropyl and n-butyl alcohols and of solutions of methyl and ethyl alcohols in benzene. The signs of the Soret coefficients for all three methods were found to be the same for all organic solutions. Results also showed that for large Soret coefficients, a convective phenomenon appears in the flow cell for both positive and negative separation factors.

Accurate estimates of infinite-dilution chemical potentials of small hydrocarbons in water via molecular dynamics simulation
Article Abstract:
The single charging integral method was used to measure the infinitely dilute residual chemical potential for methane, ethane, propane and benzene in water. The estimates for the absolute infinite-dilution chemical potentials for the four hydrocarbons were in good agreement with experimental values, indicating that the method is robust, accurate and efficient for calculating differences in residual chemical potentials.
