Linear isotherm regularities of solid sodium under pressure

Extension of Linear Isotherm Regularity to Long Chain Alkanes

In this work, we consider each normal alkane as a hypothetical mixtureof methyland methylene groups, in which the interaction potential of each pair is assumed to be the average effective pair potential. Then, the LIR equation of state (EOS) is extended for such a hypothetical mixture. Also, three basic compounds, namely, propane, n-butane and cyclohexane, are used to obtain the contributio...

EXTENSION OF LINEAR ISOTHERM REGULARITY TO LOWER DENSITY RANGE

The general equation of state which was found for dense fluids, both compressed liquids and dense supercritical fluids, namely "Linear Isotherm Regularity," is extended to the lower density range, specifically for densities lower than the Boyle density. This new equation of state which is called "ELIR" is shown to be compatible with the equations of state based on statistical-mechanical the...

Regularities of solid-phase interaction of tin and molybdenum oxides: Catalytic properties

The interaction in the system of SnO2 and h-MoO3 prepared by their joint mechanical activation in a roller-ring vibratory mill was investigated. A series of catalysts was prepared with SnO2: h-MoO3 molar ratio 1:1; 1:2.3; 2.3:1 and 5.7:1. The catalysts were characterized by various techniques including X-ray phase, X-ray diffraction (XRD) and synchron...

Melting Temperature Depression of Solid Lipid under High Pressure Gases

The effects of high pressure gases on solid lipids were investigated by high-pressure differential scanning calorimeter (DSC). In particular, the influence of a high-pressure gas on solid-liquid and solid-solid transitions were investigated for pure tristearin and a mixture of lipids (tristearin-phosphatidylcoline-dioctilsolfosuccinate). Both of these substances are commonly used for the produc...
