INTRODUCTION Several studies have demonstrated the usefulness of Synchrotron micro x-ray absorption near edge structure (XANES), or (SmX) spectroscopy, to determine the oxidation state of elements in planetary materials. Delaney et al. [1] used SmX to investigate the oxidation states Fe, Cr, and V in extraterrestrial samples, and later determined the oxidation state of V in experimental glasses...

the srk two-parameter cubic equation of state has been used for the calculation of the equilibrium constant using the liquid and vapor fugacity coefficients for three binary mixtures. dew and bubble points have been determined using the equilibrium constants and the phase envelope has been plotted showing dearly that retrograde condenstaion occurs. the following percent deviations have been obt...

The coordinate-momentum double distribution function ρ(r,p)drdp is calculated in the local density approximation for bosons with positive scattering length a in a trap. The calculation is valid to the first order of a. To clarify the meaning of the result, it is compared for a special case with the double distribution function ρwd rdp of Wigner. Using the local density approximation (LDA) [1,2]...

We study the algorithmic applications of a natural discretization for hard-sphere model and Widom–Rowlinson in region $$d $$ -dimensional Euclidean space \mathbb {V} \subset {R} ^{d}$$ . These continuous models are frequently used statistical physics to describe mixtures one or multiple particle types subjected hard-core interactions. For each type, particles distributed according Poisson point...

We consider the Asakura–Oosawa–Vrij model of hard sphere colloids and ideal polymer coils in contact with a planar hard wall at (colloidal) liquid–gas coexistence. Using extensive numerical density functional calculations, the liquid–gas, wall–liquid and wall–gas interfacial free energies are calculated. The results are inserted into Young’s equation to obtain the contact angle between the liqu...

In a recent paper with Bousquet-Mélou, de Gier, Duminil-Copin and Guttmann (2012), we proved that a model of self-avoiding walks on the honeycomb lattice, interacting with an impenetrable surface, undergoes an adsorption phase transition when the surface fugacity is 1 + √ 2. Our proof used a generalisation of an identity obtained by Duminil-Copin and Smirnov (2012), and confirmed a conjecture o...
