Ion spatial distributions at the liquid-vapor interface of aqueous potassium fluoride solutions.
X-Ray photoemission spectroscopy operating under ambient pressure conditions is used to probe ion distributions throughout the interfacial region of a free-flowing aqueous liquid micro-jet of 6 M potassium fluoride. Varying the energy of the ejected photoelectrons by carrying out experiments as a function of X-ray wavelength measures the composition of the aqueous-vapor interfacial region at va...
متن کاملOrganic component vapor pressures and hygroscopicities of aqueous aerosol measured by optical tweezers.
Measurements of the hygroscopic response of aerosol and the particle-to-gas partitioning of semivolatile organic compounds are crucial for providing more accurate descriptions of the compositional and size distributions of atmospheric aerosol. Concurrent measurements of particle size and composition (inferred from refractive index) are reported here using optical tweezers to isolate and probe i...
متن کاملVapor Pressures of Platinum , Iridium , and Rhodium
Systematic measurements of the vapor pressure of iridium and rhodium over a wide temperatme range have not been published previously. A summary of previous estimates or observations of their normal boiling points and values of their heats of sublimation, f:..H ~ (298), is given in table l. The vapor pressure of platinum was calculated by Langmuir and .Mackay from measurements of the rate of sub...
متن کاملA new modified Wilson equation for the calculation of vapor–liquid equilibrium of aqueous polymer solutions
A local composition model based on the lattice theory and two-fluid theory, considering the excess heat capacity, which is a modified Wilson equation, is developed for the excess Gibbs energy of aqueous polymer solutions. The model represents a synergistic combination of the excess entropy for mixing molecules of different sizes and the temperature dependent residual contribution, which combine...
متن کاملAqueous solutions of ionic liquids: study of the solution/vapor interface using molecular dynamics simulations.
We performed a detailed molecular dynamics study of the interfacial structure of aqueous solutions of 1-butyl-3-methylimidazolium tetrafluoroborate in order to explain the anomalous dependence of the surface tension on concentration. At low concentrations the surface tension decreases with concentration. At higher concentrations the surface becomes saturated; a plateau is observed in simulation...
