The phase diagrams of different amphiphilic molecular structures are investigated in separate simulations by employing the Gibbs Ensemble Monte Carlo method with an implemented configurational-bias technique. The computer simulations of the above mentioned amphiphilic systems are done in an area where physics, biology and chemistry are closely connected and advances in applications require the use of new theoretical, experimental and simulation methods for a better understanding of their self-assembling properties. Obtained simulation results demonstrate the connection between the structure of amphiphilic molecules and the properties of their thermodynamically stable aggregates and thus build a foundation for many applications of the remarkable phenomena of amphiphilic self-assembly in the area of nanotechnology.

Amphiphilic layers play essential roles in the behaviour of a great variety of disperse systems such as micelles, microemulsions and vesicles. They can also exist as isolated mono- or bilayers, or constitute extended liquid crystalline structures. Although the properties of these different systems may at first sight seem unrelated, theoretical interpretations of them depend on several common concepts. This was the reason for bringing together scientists working in this area for the International Winter School on the Physics of Amphiphilic Layers, which was held at Les Houches, 10-18 February, 1987. The topics treated in the proceedings volume are mono- and bilayers, interactive forces between layers (with special emphasis on steric forces), ordered structures (in particular swollen lamellar phases and defects), vesicles, micelles (including polymer-like systems), microemulsions (especially random bicontinuous structures) and porous media. The importance of thermal fluctuations in the amphiphilic layers is stressed. Recent results are presented and literature references allow readers not familiar with the subject to find any background information they require.

This work offers a comprehensive review of surfactant systems in organic, inorganic, colloidal, surface, and materials chemistry. It provides practical applications to reaction chemistry, organic and inorganic particle formation, synthesis and processing, molecular recognition and surfactant templating. It also allows closer collaboration between synthetic and physical practitioners in developing new materials and devices.

Smectic and lamellar liquid crystals are three-dimensional layered structures in which each layer behaves as a two-dimensional fluid. Because of their reduced dimensionality they have unique physical properties and challenging theoretical descriptions, and are the subject of much current research.
