Phase Diagrams of Ca3(PO4)2-Mg3(PO4)2and Ca3(PO4)2-CaNaPO4Systems

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.

Phase diagrams of mesomorphic mixtures

2014 We have combined the Maier Saupe theory [1] of the nematic-isotropic transition and the Flory Huggins theory of mixtures to describe the phase diagrams of two nematogens A + B. The two components can have different order parameters SA, SB in the mixture. We can then predict the morphology of the phase diagrams in term of a relatively small number (4) of interaction parameters. The final nu...

Simulation of Rainfall - Runoff Events by Applying Phase Differences Diagrams and Correcting Effective Rainfall Components

   The conversion of rainfall to runoff in basins includes nonlinear relations between the complex interactions of various hydrological processes. In this study, without considering of predetermined structure, relationship between input and output system was derived individually from the nature of the data recorded. Also, the phase difference occurred between rainfall and runoff signals using c...

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...
