The aim of this study is to describe the phase equilibrium behavior of aqueous solutions of selected ionic liquids (ILs) as new potential pairs of absorption cooling systems. The ILs under study have a shared cation, 1-butyl-3-methylimidiazolium, [C4mim]þ, and the following anions: methanesulfonate, [CH3SO3] , trifluoromethanesulfonate, [CF3SO3] , acetate, [CH3CO2] , trifluoroacetate, [CF3CO2] ...

An attempt is made in this work to combine the Lennard–Jones chain model (LJC) of self-diffusion coefficient with the statistical associating fluid theory (SAFT). The real non-spherical associating molecules are modeled as chains of tangent Lennard–Jones segments with association sites. An equation for the self-diffusion coefficient in a polyatomic associating fluid is presented as a product of...

In recent years, molecularly-based equations of state, as typified by the SAFT (statistical associating fluid theory) approach, have become increasingly popular tools for the modeling of phase behavior. However, whether using this, or even much simpler models, the reliable calculation of phase behavior from a given model can be a very challenging computational problem. A new methodology is desc...

The present study used data from the SAFT (Safety, Awareness, Facts and Tools) Singapore survey, a national survey of 1,124 youths aged 12-17, to explore the issue of risk on the Internet. We investigated factors that influence adolescents' engagement in risky Internet behavior, in particular, meeting face-to-face someone they first encountered online. The adolescents ranged from ages 12 to 17,...
