From random sequential adsorption to ballistic deposition: a general view of irreversible deposition processes

Article Abstract:

Research concerning the role played by steric effects on the deposition of macromolecules on solid surfaces is presented. The process involves the experimental testing of models of ballistic deposition and random sequential adsorption under the influence of strong and negligible gravity.

Modeling the buildup of polyelectrolyte multilayers film having exponential growth

Article Abstract:

A model for the buildup of exponentially growing films that allows a discussion of the behavior of them in a unified manner is presented. This model is based on an "inward" and "outward" diffusion process, throughout the entire film, of at least one of the polyelectrolytes that comprise the multilayer.

Relationship between the growth regime of polyelectrolyte multilayer and the polyanion/polycation complexation enthalpy

Article Abstract:

A study was conducted to establish a correlation between the nature of the growth process and the heat of complexation between the polyanions and the polycations constituting the polyelectrolyte multilayer films (PEM). Weakly exothermic processes seem to be associated with weakly exponentially growing films which show that exponentially growing processes are mainly driven by entropy.
