Deliquescence in Binary Mixtures
Pharmaceutical Research, 2005Deliquescence is a first-order phase transformation from solid to solution and occurs at a specific relative humidity (RH) that is characteristic to the solid. The goal of this research was to investigate the reduction in critical relative humidity (RH0) in binary solid mixtures of deliquescent active pharmaceutical ingredients (APIs) and deliquescent ...

Spinodal decomposition in binary mixtures
Physical Review E, 1996We study the early stage of the phase separation of a binary mixture far from its critical point of demixing. Whenever the mixture of two mutually repulsive species is quenched to a temperature below its critical point of miscibility, the effect of the enthalpic repulsive force prevails upon the entropic tendency to mix, so that the system eventually ...

Binary mixtures of magnetic fluids
Physical Review E, 2003We study a binary mixture of a van der Waals fluid and a ferromagnetic fluid at zero magnetic field on the basis of the mean field Ising fluid model and the van der Waals theory with quadratic mixing rules. Depending on three reduced parameters, the phase diagram shows a surface of magnetic phase transitions and lines of tricritical points, critical ...

Odour suppression in binary mixtures
Biological Psychology, 2006It has been suggested that odours causing stronger trigeminal activation suppress weaker trigeminal stimuli and that mixed olfactory-trigeminal stimuli suppress odorants that only activate one of these systems. Volunteer normosmic participants (n=20) were exposed to six odorants with varying trigeminal impact to test the hypothesis that more intense ...

Interdiffusion in binary ionic mixtures
Physical Review A, 1987In this paper we present molecular-dynamics and kinetic-theory calculations of the interdiffusion coefficients in dense binary ionic mixtures for conditions appropriate to both astrophysical and inertial-confinement fusion (ICF) plasmas. The diffusion coefficient is the product of a Green-Kubo integral and a thermodynamic prefactor.

Excess compressibility in binary liquid mixtures
The Journal of Chemical Physics, 2007Brillouin scattering experiments have been carried out on some mixtures of molecular liquids. From the measurement of the hypersonic velocities we have evaluated the adiabatic compressibility as a function of the volume fraction. We show how the quadratic form of the excess compressibility dependence on the solute volume fraction can be derived by ...

Odorntensity interaction in binary mixtures.
Journal of Experimental Psychology: Human Perception and Performance, 1993Four principles underlying odor summation in mixtures were examined on the bases of 10 Ss' magnitude estimates of 41 mixtures and their components (pyridine and DMDS). Thus, the overall intensity summation for mixtures are compared to self-addition reflected by the power function for single substances: Hypoaddition is a characteristic of both ...

Oscillatory convection in binary mixtures
Physical Review A, 1986Two-dimensional oscillatory convection in a binary fluid mixture in an infinite plane porous layer heated from below is studied. Small-amplitude nonlinear solutions in the form of standing and traveling waves are found and their relative stability is established. Stable traveling waves are preferred near onset.

Abstract Binary mixtures will here be considered as a mixture of a fluid substance, such as those described in Chapter 1, which will be always called component 1, and a second substance, component 2. The binary mixtures that are important in supercritical fluids broadly fall into two areas, d pending on the molar mass and critical ...

Physica A: Statistical Mechanics and its Applications, 1996
The nucleation kinetics of a binary mixture is studied using a Gibbs free energy function that we have recently used to obtain a range of generic phase diagrams when liquid mixtures are cooled to solid state. This allows us to compute analytically all the quantities related to the free energy barrier that occur in the nucleation kinetic equation.
