Multilayer Adsorption of Polyatomic Species on Homogeneous and Heterogeneous Surfaces

In this work we study the multilayer adsorption of polyatomic species on homogeneous and heterogeneous bivariate surfaces. A new approximate analytic isotherm is obtained and validated by comparing with Monte Carlo simulation. Then, we use the well-known Brunauer-Emmet-Teller’s (BET) approach to analyze these isotherms and to estimate the monolayer volume, vm. The results show that the value of...

Continuum Approaches for Describing Solid-Gas and Solid-Liquid Flow

Two-phase continuum models have been used to describe the multiphase flow properties of solid-gas and solid-liquid mixtures. The approach is limited in that it requires many fitting functions and parameters to be determined empirically, and it does not provide natural explanations for some of the qualitative behavior of solid-fluid flow. In this report, we explore a more recent single-phase con...

Monte Carlo Simulation of Protein Adsorption on Energetically Heterogeneous Surfaces

The modified triangular-well potential model was applied to incorporate the effect of surface energy on the adsorption of particles or proteins on energetically heterogeneous surfaces. The method is convenient in simulating the adsorption on heterogeneous surface of which different region possesses different free energy. Spherical particles with attractive forces were added on the surface and u...

Adsorption of Proteins at Solid-Liquid Interfaces

This paper concisely rev iews the general principles underlying protein adsorption from aqueous so lution onto a solid surface. The discussion includes the various stages of the adsorption process, i. e., transport o f the protein molecules towards the su rface, the absorbed amount under equilibrium conditions, desorption andreadsorption. Among the interactions that determine the overall protei...
