Formation of binary ion clusters from polar vapours

Formation of binary ion clusters from polar vapours: effect of the dipole-charge interaction

Formation of binary cluster ions from polar vapours is considered. The effect of vapour polarity on the size and composition of the critical clusters is investigated theoretically and a corrected version of classical KelvinThomson theory of binary ion-induced nucleation is derived. The model predictions of the derived theory are compared to the results given by classical binary homogeneous nucl...

Conductometric study of the complex formation of Rb+, Cs+, NH4 +, K+, Tl+ and Ag+ ions with several crown ethers in acetonitrile-dimethylsulfoxide and acetonitrile-dimethylformamide binary mixtures

A conductance study of the interaction between Cs+, Rb+, NH4+, K+, T1+ and Ag+ ions and18-crown-6 (18C6), benzo-18-crown-6 (B18C6), dicyclohexyl-18-crown-6 (DC18C6),dicyclohexyl-24-crown-8 (DC24C8), dibenzo-24-crown-8 (DB24C8) in different binarymixtures of acetonitrile (AN) with dimethylsulfoxide (DMSO) and dimethylformamide (DMF)at 25 °C has been carried out. Formation constants of the result...

Kinetic nucleation and ions in boreal forest particle formation events

In order to gain a more comprehensive picture on different mechanisms behind atmospheric particle formation, measurement results from QUEST 2-campaign are analyzed with an aid of an aerosol dynamic model. A special emphasis is laid on air ion and charged aerosol dynamics. Model simulations indicate that kinetic nucleation of ammonia and sulphuric acid together with condensation of sulphuric aci...

Thermodynamic Study of L-alanine in Aqueous Solutions of 1-Hexyl-3-Methylimidazolium Ibuprofenate as an Active Pharmaceutical Ingredient Ionic Liquid (API-IL)

The present work reported density, viscosity, speed of sound, electrical conductivity and refractive index data of L-alanine in the aqueous solutions of 1-hexyl-3-methylimidazolium ibuprofenate at T= 298.15 K. Using the measured data, partial molar volume of transfer ( ), partial molar isentropic compressibility of transfer ( ), viscosity B-coefficient of transfer (∆traB), ion association const...
