fugacity

/fu·gac·i·ty/ (fu-gas´it-e) a measure of the escaping tendency of a substance from one phase to another phase, or from one part of a phase to another part of the same phase.

To further investigate the behavior of MeOH toward FKM-66, absorption measurements were conducted with pure MeOH vapor at ambient temperature with a fugacity of 0.
i] is fugacity coefficient of component i in the mixture and Z is given in Equation (1).
The hydrogen activities calculated in terms of equivalent pressure or fugacity are clearly much greater than atmospheric pressure and hydrogen gas bubble nucleation can be expected when the surface remains bare for any significant length of time in these environments.
Values for the fugacity coefficient [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] are similar to those previously observed (Morris et al.
Hydrogen fugacity has been shown to have a pronounced effect on the solubilities and melting temperatures of chaleopyrite (Mavrogenes and Bodnar 1994).
This obviously requires a calculation of the contributors' incomes that implies to consider the different possible incomes obtainable in a certain period of time from taxable goods and the degree of fragility and fugacity that these incomes could have in the future.
3+]/[SIGMA]Fe in minerals and silicate glasses can be used to investigate oxygen fugacity in the mantle (McCanta et al.
Specific topics include mantle geochemical heterogeneities, quantitative interpretation of global seismic tomography, numerical and laboratory studies of mantle convection, the role of theoretical mineral physics in modeling the Earth's interior, mantle oxidation state and oxygen fugacity, thermochemical state of the lower mantle, stability of MgSiO3 Perovskite in the lower mantle, synthetic tomographic images of slabs from mineral physics, and compositional dependence of the elastic wave velocities of mantle minerals.
Building on my reflections in "Il concetto del tempo nella Divina Commedia" (Fu Jen Studies 35), it emphasizes the different sensibility with which Petrarch perceives the flow of time in an era that--with the advent of the mechanical clock and new urban rhythms of work--was keenly aware of time's fugacity and the need for human control over it.
In this poster, the importance of working with the chemical potential instead of the logarithm of fugacity coefficient in the calculation of phase equilibria has been explored for a cubic equation of state (EOS) as well as for a complex EOS.
Finally, in discussing the "architecture" of each collection and the relationship of chapters to the whole, Bichard-Thomine discerns a youthful fugacity and a structure that is more delineated and closed in the Propos than in the much later Contes et Discours.
