In this study, Ba3SrNb2O9(s) was synthesized using conventional solid-state reaction route, characterized by powder XRD and SEM-EDAX. The standard molar enthalpy of formation determined measuring enthalpies solution in {PbO + B2O3} solvent (in 2:1 ratio) at T = 966 K an oxide melt high temperature calorimeter. increment measured with same heat capacity the also employing DSC. Based on smoothed ...
Recent years have seen a tremendous progress in the microscopic theoretical treatment of surfaces and processes on surfaces. While some decades ago a phenomenological thermodynamic approach was dominant, a variety of surface properties can now be described from first principles, i.e. without invoking any empirical parameters. Consequently, the field of theoretical surface science is no longer l...
In this work we extend the crossover (CR) modification of the statistical-associating-fluid-theory (SAFT) equation of state (EOS), recently developed and applied for non-associating systems [Ind. Eng. Chem. Res. 38 (1999) 4993] to associating fluids. Unlike the previous crossover EOS that was based on the parametric linear model for the universal crossover function Y, the new CR SAFT EOS is bas...
