Solubility Determination of Barely Aqueous-Soluble Organic Solids
Journal of Pharmaceutical Sciences, 1979Solubility determination of organic molecules having very low solubilities is hampered by such problems as slow equilibration during measurement, influence of impurities, and inherent heterogeneity in the energetic content of the crystalline solid. Three approaches to meeting these problems are presented.

Soluble factors and solid phases
Current Biology, 1992Macromolecules are constantly being transported between nucleus and cytoplasm in a selective, signal- dependent manner. This dynamic flux consists of the unidirectional transport of certain proteins and RNA molecules, and the bidirectional transport or ‘shuttling’ of other proteins and ribonucleoprotein particles.

Solid solubility limit in alloying nanoparticles
Nanotechnology, 2006In order to gain a better thermodynamic understanding of the phase diagram of alloying nanoparticles, we establish a size-dependent solid solubility model of binary metallic systems to elucidate the anomalous solid solubility in nanometre-sized alloying particles.

The solubility of solids in gases
Economic Geology, 1957That gases can dissolve solids has been known since the work of Hannay in 1879-1881. The historical and theoretical aspects of this phenomenon are discussed, and the literature of the subject is summarized and reviewed. Some previously unpublished results from the Geophysical Laboratory on the solubility of UO 2 , Al 2 O 3 , NiO, Nb 2 O 5 , Ta 2 O 5 ...

Extended Solubility Approach: Solubility Parameters for Crystalline Solid Compounds
Journal of Pharmaceutical Sciences, 1981A method is suggested to obtain solubility parameters for crystalline solid compounds involving a quadratic equation based on the original Scatchard-Hildebrand solubility expression. The geometric mean delta 1 delta 2, of the Hildebrand approach is replaced by w12 = K delta 1 delta 2, and log alpha 2/(V2 phi 2(2)/2.3RT) is regressed against delta 1 in ...

Development of Solid Lipid Nanoparticles for Enhanced Solubility of Poorly Soluble Drugs
Journal of Biomedical Nanotechnology, 2010Cyclosporine (CyA) solid lipid nanoparticles were prepared by using a solvent free high pressure homogenization process. CyA was incorporated into SLNs that consisted of stearic acid, trilaurin or tripalmitin lipid solid cores in order to enhance drug solubility.

Solubility of solids in liquids: one-parameter solubility equation
Fluid Phase Equilibria, 1986Abstract Buchowski, H. and Khiat, A., 1986. Solubility of solids in liquids: one-parameter solubility equation. Fluid Phase Equilibria, 25: 273–278. A new equation for solubility curves has been established based on the variation of vapour pressure over saturated solutions.

Solubility of Dicalcium Phosphate Dihydrate by Solid Titration
Caries Research, 2009Solid-titration results for hydroxyapatite (HAp), octacalcium phosphate, β-tricalcium phosphate and tetracalcium phosphate have shown that the only stable phase in 100 mmol·l<sup>-1</sup> KCl at 37°C is HAp. In particular, dicalcium phosphate dihydrate (DCPD) did not form at pH <4.2 (where it is otherwise believed to be stable) except as
