True Phase Diagrams

Geochemical Phase Diagrams and Gale Diagrams

The problem of predicting the possible topologies of a geochemical phase diagram, based on the chemical formula of the phases involved, is shown to be intimately connected with and aided by well-studied notions in discrete geometry: Gale diagrams, triangulations, secondary fans, and oriented matroids.

True single-phase adiabatic circuitry

Dynamic logic families that rely on energy recovery to achieve low energy dissipation control the flow of data through gate cascades using multiphase clocks. Consequently, they typically use multiple clock generators and can exhibit increased energy consumption on their clock distribution networks. Moreover, they are not attractive for high-speed design due to their high complexity and clock sk...

Protein crystallization and phase diagrams.

The phase diagram is a map which represents the state of a material (e.g., solid and liquid) as a function of the ambient conditions (e.g., temperature and concentration). It is therefore a useful tool in processing many different classes of materials. In this article, methods to determine the phase diagram of an aqueous solution of a globular protein are described, focusing on the solid (cryst...

Lecithin Based Pseudoternary Phase Diagrams

Aim: Different promising colloidal delivery systems including microemulsions and liquid crystals could be obtained with suitable combination of oil, surfactants/cosurfactants and water. However, the main problem from a formulation point of view has been to choose the surfactants capable of forming such systems and be physiologically acceptable in the same time. To overcome the later shortcoming...
