Thermodynamics of binary methanol solutions

Thermochimica Acta, 1976
Abstract Excess enthalpies and change in volumes on mixing methanol with pyridine, β-picoline, N-N,-dimethylformamide and 1,4-dioxane have been determined at 303.15 K and 308.15 K and the same have been analysed for Barker's theory. It has been concluded that whereas the interaction of pyridine and β-picoline with methanol is attended by a decrease ...

Raman Intensity in Binary Solutions

The Journal of Chemical Physics, 1966
Relative to the intensity in pure solvent, the integrated intensity of a Raman band in solution decreases not linearly with molar concentration, but more or less rapidly as the refractive index of the solution rises or falls on addition of solute. This behavior is treated here as a consequence of excited-state interactions between the components of the

Chemical potential of a binary solution

Technical Physics Letters, 1999
The chemical potential of a binary solution is calculated using the Gibbs free energy method. With the aid of certain assumptions on the microscopic structure of the solution, the well-known expression is derived for a simple solution. It is shown that the empirical interaction parameter is expressed in terms of the change in enthalpy and entropy ...

Kinetics of crystallization in binary solutions

Kristall und Technik, 1981
AbstractA two‐dimensional nucleation is required to grow the crystals of low energy planes. Expressions for the size and free energy of the two‐dimensional nucleus corresponding to a saddle point in binary system are derived. The concentration of the critical nuclei in the system is related to the critical free energy of the two‐dimensional nucleus.

Theory of binary boson solutions

Annals of Physics, 1972
Abstract The theory of binary boson solutions is derived by an extension of the paired-phonon analysis previously applied to liquid 4 He. The results include expressions for an approximate ground state energy and wavefunction. the latter is composed of a product of a Jastrow factor and the correlation function employed in a correlated basis.

Linear partitioning in binary solutions

Geochimica et Cosmochimica Acta, 2000
In a continuous binary solution, the partition coefficient, expressed as a ratio of mole fractions of one component in two phases, is linear against the composition of one of the phases (the numerator phase) if the exchange coefficient KD is constant. Linearity is found in some distilling liquids, many silicate and metal alloy melts, and many mineral ...

Non‐Ideal Behaviour and Solution Interactions in Binary DMSO Solutions

ChemPhysChem, 2015
AbstractThe structure and dynamics of hydrogen‐bonded structures are of significant importance in understanding many binary mixtures. Since self‐diffusion is very sensitive to changes in the molecular weight and shape of the diffusing species, hydrogen‐bonded associated structures in dimethylsulfoxide–methanol (DMSO–MeOH) and DMSO–ethanol (DMSO–EtOH ...

Simulation of the nucleation and growth of binary solid solutions in aqueous solutions

Chemical Geology, 2010
Abstract We present a model which, for the first time, accounts for nucleation, growth and/or resorption of particles of variable composition in aqueous solutions (AS). Devised for describing the precipitation of binary solid solutions, it yields the time evolution of all ion activities in the AS, together with the particle population characteristics:

Orbital solutions for the OSSOS binaries

2019
The OSSOS Survey discovered more than 800 Trans-Neptunian Objects between 2013 and 2017. Among them were at least 5 binaries. We here present orbital solutions for binary objects, based on OSSOS images, supplemented by additional surveys. We obtained the orbital solutions thanks to a Markov Chain Monte Carlo algorithm, in a 6-dimensional phase space ...
