Demonstrating Encapsulation and Release: A New Take on Alginate Complexation and the Nylon Rope Trick  Andrienne C. Friedli and Inge R. Schlager
Three variations on a classroom demonstration of the encapsulation of droplets and evidence for release of the interior solution are described. The first two demonstrations mimic biocompatible applications of encapsulation. A third encapsulation exercise exploits the irreversible interfacial polymerization of diamine and diacid chloride to form membranes and illustrates the detection of diamine release from the capsule using an indicator.

Illustrating Chemical Kinetic Principles with Ion Motions in Thin Membranes  Michael E. Starzak
Ions dissolved in thin membranes follow first order kinetics when they are moved between interfacial states by an applied electrical potential. The two state system is ideal to describe basic chemical kinetic concepts such as detailed balance at equilibrium and possible time dependence in the rate constants.

Consequences of the lipid bilayer to membrane-associated reactions  Eze, Michael O.
The bilyaer is a very important component of the cell, and consequently fluidity changes within the liquid crystalline state, as well as changes from gel to liquid crystalline, must have profound effects on these membrane functions, and on functions that occur within the membrane.
