We present a novel, thermodynamically consistent modification of the Pitzer-Debye-Hückel term and its extension for concentration dependent density, molar mass relative permittivity. This is validated ionic liquids by comparison with reference model from literature and, in contrast to similar extensions, also applied conventional salts small spherical ions aqueous, mixed non-aqueous solvents. T...

Abstract Smart gravimetric and swelling techniques were utilized in this work to examine the validity of Debye Hückel length (κ −1 ) equation when shale interacts with highly concentrated salt solutions. The shrinkage behavior two different shales, exposed monovalent divalent ionic solutions (NaCl, KCl CaCl 2 at concentrations ranging from 22%w/w was observed measured. Shale results show that s...

The first excited $$J^{\pi }=0^+$$ state of $$^{12}$$ C, the so-called Hoyle state, plays an essential role in a triple- $$\alpha $$ ( $$^{4}$$ He) reaction, which is main contributor to synthesis C burning star. We investigate Coulomb screening effects on energy shift thermal plasma environment using precise three- model calculations. effect between clusters taken into account within Debye-Hüc...

using solvent evaporating and atomic emission spectrophotometric methods, the solubility of li2co3 in waterat 25°c was determined. comparing the value of thermodynamic solubility product constant, ksp(th),(ksp(tn) = exp(—ag.ss/rt)) of the mentioned salt to the value which is obtained from the observed solubility,shnoll-1 , and activity coefficients, f+ and f, which are estimated upon the extend...

Radionuclides are inorganic substances, and the solubility of substances is a major factor affecting disposal radioactive waste release concentrations radionuclides. The degree determines whether nuclide source migrates to far field site. Therefore, most effective method for retarding radionuclide migration reduce in aqueous geochemical environment subsurface systems. In order assess performanc...

Thermodynamic quantities of Coulomb plasmas consisting of point-like ions immersed in a compressible, polarizable electron background are calculated for ion charges Z = 1 to 26 and for a wide domain of plasma parameters ranging from the Debye-Hückel limit to the crystallization point and from the region of nondegenerate to fully degenerate nonrelativistic or relativistic electrons. The calculat...

We review recent advances in the physics of strongly interacting charged systems functioning in water at room temperature. We concentrate on the phenomena which go beyond the framework of mean field theories, whether linear Debye-Hückel or non-linear Poisson-Boltzmann. We place major emphasis on charge inversion-a counterintuitive phenomenon in which a strongly charged particle, called macroion...

This report briefly describes the development and applications of net-sign graph theory. The current work enunciates the graph (molecule) signature of nonalternant non-benzenoid hydrocarbons with odd member of rings (non-bipartite molecular graphs) based on chemical signed graph theory. Experimental evidences and Hückel spectrum reveal that structure possessing nonbonding molecular orbital (NBM...
