Scaled experimentation is an important experimental approach but known to be limited by scale effects, which have the undesirable effect of changing behaviour a system with scale. Such behavioural changes can on occasions so marked as make scaled experiment almost worthless. Until very recently, there has been no universal solution this problem most experiments founded dimensional analysis and ...

Using’the concepts of scaled particle theory, an analytical theory is developed to investigate the limiting behavior of solvation free energies at the particle creation limit. The new theory directly incorporates the weakly attractive, dispersion interaction terms into the analytical calculations. For neutral molecular systems, the effects of longer ranged electrostatic interactions are also in...

The Sound attenuation and dispersion in saturated gas-vapor-droplet mixture in the presence of evaporation has been investigated theoretically. The theory is based on an extension of the work of Davidson (1975) to accommodate the effects of nonlinear particle relaxation processes of mass, momentum and energy transfer on sound attenuation and dispersion. The results indicate the existence of a s...

Hydrophobic hydration plays a crucial role in self-assembly processes over multiple length-scales, from the microscopic origins of inert gas solubility in water, to the mesoscopic organization of proteins and surfactant structures, to macroscopic phase separation. Many theoretical studies focus on the molecularly detailed interactions between oil and water, but the extrapolation of molecular-sc...

We reformulate Rosenfeld’s fundamental-measure theory using the excess Helmholtz energy density from the Boublik–Mansoori–Carnahan–Starling–Leland equation of state instead of that from the scaled-particle theory. The new density functional theory yields improved density distributions, especially the contact densities, of inhomogeneous hard-sphere fluids as well as more accurate direct and pair...
