THERMODYNAMICS OF LIQUID NITROGEN SOLUTIONS IN CHROMIUM

Thermodynamics of Polymer Solutions

Most of the synthetic compounds are prepared and processed in the liquid state, i.e. in solution or in the molten state. Detailed knowledge on this state is therefore indispensable. In particular it is essential to know the limits of complete miscibility with a low molecular weight solvent as a function of temperature, pressure and composition. Furthermore it is often mandatory to be acquainted...

Fermi Liquid Theory: Thermodynamics

I have chosen to use a spin notation of “up” or “down” with respect to a convenient z axis rather than a more rotationally invariant formulation. The quantity εp is not the same as in the interacting system, but can be expanded in the same way about p = pF εp = εF + vF (p − pF )+ · · · (3) where εF , vF are not the same as in the noninteracting system. The single quasiparticle energy does not d...

Nitrogen in chromium–manganese stainless steels: a review on the evaluation of stacking fault energy by computational thermodynamics

Nitrogen in austenitic stainless steels and its effect on the stacking fault energy (SFE) has been the subject of intense discussions in the literature. Until today, no generally accepted method for the SFE calculation exists that can be applied to a wide range of chemical compositions in these systems. Besides different types of models that are used from first-principle to thermodynamics-based...

Montmorillonite Nanoparticles in Removal of Textile Dyes from Aqueous Solutions: Study of Kinetics and Thermodynamics

Dyeing wastewaters are one of the most common pollutants that cause many problems for public health and environment due to dermatitis and skin rashes, cancer production, mutagenesis, etc. Thus, treatment of these wastewaters is necessary. The purpose of this study was to investigate the efficiency of montmorillonite nanoparticles as an adsorbent in adsorption process of Reactive Ye...
