Study on vapor-liquid equilibria and surface tensions for nonpolar fluids by renormalization group theory and density gradient theory

Article Abstract:

The Equation of State (EOS) with the Renormalization Group Theory (RGT) was used to investigate the vapor-liquid -phase equilibria and surface tensions for 10 nonpolar chainlike fluids from low temperature up to the critical point. The experimental data results shows that inside the critical region, the classical EOS over predicts the surface tensions due to the overestimation of the critical temperature, while RG correction, DGT correctly predicts the surface tensions inside the critical region.

Sensing cantilever beam bending by the optical lever technique and its application to surface stress

Article Abstract:

A general equation is developed that permits the true deflection of the cantilever to be obtained from the measurement of the deflection for uniformly distributed loadings and end-moment loadings. The application of the general equation to an applied surface stress is discussed.

Usage, Cantilever beams

Revealing the influence of the strength of Coulomb interactions on the viscosity and interfacial tension of ionic liquid cosolvent mixtures

Article Abstract:

The various effects of the strength of the Coulomb interactions on the properties of selected ionic liquid cosolvent mixtures are analyzed. The analysis reveals that the dielectric constants of these mixtures are inversely related to their viscosity.
