immiscibility

This immiscibility is due to at least one difference between the two substances' corresponding physical properties.

Octanol's immiscibility leads it to be used as a standard for partition equilibria.

Dilution refrigerators use this immiscibility to achieve temperatures of a few millikelvins.

Net-textured ore is rarely observed, being the ideal condition of sulfide-silicate immiscibility.

PBC is needed because the immiscibility of aqueous phase and organic substrate.

Liquid immiscibility: sulfide ores containing copper, nickel or platinum may form from this process.

Liquids can display immiscibility.

Immiscibility occurs when the intermolecular bonds of one liquid are too strong to be broken by any attractive forces of the other liquid.

These deposits are formed by melt immiscibility between sulfide and silicate melts in a sulfur-saturated magma.

Graphic texture is commonly created by exsolution and devitrification and immiscibility processes in igneous rocks.

The immiscibility gaps in the plagioclase solid solutions are complex compared to the gap in the alkali feldspars.

The cause of this immiscibility is uncertain, but the immiscibility is thought to minimize the free energy between the two phases.

Again, the immiscibility of most epoxy and acrylic resins with water necessitates the use of dehydration, usually with ethanol.

One example of immiscibility in metals is copper and cobalt, where rapid freezing to form solid precipitates has been used to create granular GMR materials.

It is chosen because of its low melting point (271 C), low vapor pressure, good solubility for lithium and actinides, and immiscibility with molten halides.

These rocks apparently form by the extreme fractional crystallization of magnesian suite or alkali suite magmas, although liquid immiscibility may also play a role.

Komatiitic nickel-copper sulfide deposits are considered to be formed by a mixture of sulfide segregation, immiscibility, and thermal erosion of sulfidic sediments.

Although butanol is shown to remove more lignin than other solvents and solvent recovery is simplified due to immiscibility in water, its high cost limits its use.

Only limited solid solution occurs between K-feldspar and anorthite, and in the two other solid solutions, immiscibility occurs at temperatures common in the crust of the earth.

Ethanol's miscibility with water contrasts with the immiscibility of longer-chain alcohols (five or more carbon atoms), whose water miscibility decreases sharply as the number of carbons increases.

An example for the immiscibility of oil and water is a leak of petroleum from a damaged tanker, that does not dissolve in the ocean water but rather floats on the surface.

Rietveld & Simons related lipid rafts in model membranes to the immiscibility of ordered (Lo phase) and disordered (Ld or Lα phase) liquid phases.

Each phase (i.e. liquid, solid etc.) of physical matter comes to an end at a transitional point, or spatial interface, called a phase boundary, due to the immiscibility of said matter with the matter on the other side of said boundary.

By contrast the composition of the water/ethanol azeotrope discussed earlier is not affected enough by pressure to be easily separated using pressure swings and instead, an entrainer may be added that either modifies the azeotropic composition and exhibits immiscibility with one of the components, or extractive distillation may be used.
