Solubility Determination from Clear Points upon Solvent Addition

Solubility and solvation in mixed solvent systems

The solubility of solutes in mixed solvents depends primarily on the solvation of the solutes or their constituent ions by the components of the solvent mixtures. Complications may arise if different crystal solvates are formed or if solute-solute interactions are appreciable. In their absence the standard molar Gibbs energies of solution measure the corresponding quantities of solvation, ASOIV...

Determination of Solubility Parameters and Thermodynamic Properties in Hydrocarbon-solvent Systems by Gas Chromatography

Gas chromatography used to calculate the specific retention volume of several hydrocarbons in different chromatographic liquid phases (Squalane, Carbowax-400, Carbowax-1500, Carbowax-4000, Amine220, Dinonyl phthalate, Tributyl phosphate and Trixylenyl phosphate). Some thermodynamic parameters, such as enthalpy of sorption and Flory-Huggins parameters relating the interaction between liquid phas...

The Optimum Addition of Points

Determination of Ego-Motion from Matched Points

We propose an algorithm for the estimation of the motion of a camera moving through a static environment (ie. the ego-motion) from matched points on two images. The algorithm correctly weights the observations by minimising point mis-match distances on the image-plane. Prior knowledge concerning the camera motion may also be included. The algorithm is iterative, but generally converges quickly....

Structuring of polymer solutions upon solvent evaporation.

The morphology of solution-cast, phase-separated polymers becomes finer with increasing solvent evaporation rate. We address this observation theoretically for a model polymer where demixing is induced by steady solvent evaporation. In contrast to what is the case for a classical, thermal quench involving immiscible blends, the spinodal instability initially develops slowly and the associated l...
