	abstract = {We use the thermodynamic behaviour of I-propanol (1P) as a probe in ternary 1P-salt-H2O systems to elucidate the effect of a salt on the molecular organization of H2O. For salts, we have chosen CaCl2, NH4Cl, and (CH3)(4)NCl (TMAC). Having fixed the counter anion at Cl-, we compare here mainly the effects of chosen cations on H2O. Together with an earlier study on NaCl, we found that Ca2+, Na+, and NH4+ are hydrated by a number of H2O molecules and leave the bulk H2O away from the hydration shell unperturbed. The hydration numbers were found to be 6.4 +/- 1.6, and 1.2 +/- 0.4, for Ca2+ and NH4+, respectively with the hydration number 5.2 for Na+, the result of a simulation study, chosen as a reference. Thus, a salting out (also referred to as structure making, stabilizing, or kosmotropic) tendency would decrease in the order; Ca2+ > Na+ > NH4+. TMA(+), on the other hand, showed a more hydrophilic characteristics than the probing 1P. Thus, TMA(+) is rather chaotropic (salting in, structure breaking or destabilizing) within this methodology.},

	abstract = {The Kirkwood-Buff integrals of acetone-water mixtures are determined using two experimental techniques: small-angle neutron scattering and vapor pressure measurements, in order to test the precision and reliability that can be achieved. The data are then compared with those previously reported by different authors, which tend to show considerable variation between them. The various possible sources of inaccuracies are pointed out, both from experimental origins and from the numerical treatment of the data. Comparison with recent simulation results allows to critically compare different models and provide some information about the microstructure of the aqueous mixture.

	abstract = {The enthalpic interaction functions introduced by us earlier were evaluated in some ternary aqueous solutions. They are determined purely experimentally without resorting to any model system. From them, the pair interaction coefficients based on the virial expansion were evaluated, which will serve for a future theoretical development based on the McMillan-Mayer theory of solution. Secondly, our new methodology of using the mole fraction dependence of the enthalpic interaction function as a probe to elucidate the effect of a third component on the molecular organization is introduced. The conclusions for selected third components in ternary aqueous 1-propanol are reviewed.},

	abstract = {We measured excess chemical potentials, mu (E)(i), excess partial molar enthalpy, H-i(E), of solute i in aqueous acetone and tetramethyl urea (TMU). We then evaluated excess partial molar entropy, S-i(E). They all were determined accurately and in small increments in mole fraction, and hence, it was possible to take one more derivative with respect to mole fraction. These higher derivatives were used to learn more about intermolecular interaction in solution. Furthermore, they were used to detect anomalous thermodynamic behaviour, in particular a qualitative change in mixing scheme. We conclude that in both aqueous solutions, three distinctively different mixing schemes are operative depending on the composition range, and that in the most H2O-rich region, solute molecules enhance the hydrogen bond network of H2O in their immediate vicinity. However, the hydrogen bond probability in the bulk of H2O away from solute is reduced. (C) 2000 Elsevier Science B.V. All rights reserved.},
