	Controlled delivery of immiscible materials into an aqueous system - Patent 4440542
		As the silica-silicate foams are gradually dissolved, the immiscible components are released.
		Materials normally insoluble and immiscible in aqueous systems may be released in a controlled manner into such systems by adsorbing and trapping the materials on and into the interstices of a water-soluble inorganic foamed structure i.e., a silica-silicate foam.
		The immiscible components are adsorbed onto the foam and trapped within the voids which are inherent to the foam's structure.

	immiscibles
		When an immiscible alloy is cooled, it will separate from a single solution into a mixture of the lighter component lying on top of the heavier one.
		However, as an immiscible alloy metal is cooled, it reaches the (consolute) temperature where the atoms begin to glob together to form droplets.
		Only one previous study on stable immiscible systems was performed using a completely containerless processing technique [11] and the results of that investigation are similar to the emulsion studies.

	Immiscible Liquids
		Immiscible liquids are liquids that do not dissolve in one another.
		If the liquids were immiscible, the water and alcohol molecules would be each confined to only one liter of volume.
		They are immiscible because they have different densities, or specific gravities.

	RedOrbit - Technology - Bicomponent Fibers Derived From Immiscible Polymer Blends (Site not responding. Last check: 2007-10-13)
		This study investigates the use of immiscible polymer blends as the sheath component in bicomponent fibers with a polypropylene core.
		Such polymer blends are immiscible because of thermodynamic instabilities, and they generate a microstructure that is a function of their processing conditions [9, 16].
		The extent of surface irregularities is affected by the microstructure of the dispersed phase, i.e., fibrillar PAO as opposed to ellipsoidal PS.

	Laboratory 6 - Blending of Immiscible Liquids
		An emulsion is a system of two immiscible substances, one of which is dispersed in globular form throughout the other substance.
		When two immiscible liquids, such as oil and water, are in contact, interfacial tension causes each liquid to maintain as small a surface as possible.
		As the interfacial tension is a measure of the force to be overcome in mixing two immiscible liquids and substance which lowers interfacial tension will facilitate the preparation of an emulsion.

	Immiscible Polymer Blends
		Immiscible blends of polystyrene and polybutadiene are sold commercially under the name high-impact polystyrene, or HIPS for short.
		Another immiscible blend you may be familiar with is one made from a polyester called poly(ethylene terephthalate) and poly(vinyl alcohol).
		Remember, the two polymers in an immiscible blend don't like each other, and the smaller the surface area of the spheres, the less the two polymers have to touch each other.

		Physical effects of cholesterol on arterial smooth muscle membranes: evidence of immiscible cholesterol domains and alterations in bilayer width during atherogenesis -- Tulenko et al.
		Under normal conditions of cholesterol (0.5:1 C:PL mole ratio), the oriented samples produced a single lamellar phase with a d -space of 58 Å (Figure 6a), consistent with the periodicity measured for intact and reconstituted cardiac plasma membranes (31) (32).
		The immiscible cholesterol phase forms by phase separation as the membrane "saturates" with cholesterol.

	Miscible - Wikipedia, the free encyclopedia
		For example, in the alcohols, ethanol has two carbon atoms and is miscible with water, whereas octanol has eight carbon atoms and is not miscible with water.
		Octanol's immiscibility leads it to be used as a standard for partition equilibria.
		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.

	Permeability of Airand Immiscible Organic Liquids in Porous Media (Site not responding. Last check: 2007-10-13)
		A new equation that accounts for swelling and for the gas slippage effect in very small pores was formulated for use with these methods The observed conductivities, spanning seven orders of magnitude, agree reasonably well with calculated values.
		Only three soil parameters are required to calculate the conductivities: (1) the saturated conductivity of water, (2) the saturated conductivity of the immiscible fluid of interest, and (3) a pore size index value that is obtained from an estimate from the water release curve of the porous material.
		Remediation of organic liquid spills is briefly discussed to illustrate the practical applications of gas phase conductivities, as well as those for immiscible organic liquid phases.

	immiscible liquids and steam distillation
		Immiscible liquids are those which won't mix to give a single phase.
		Obviously if you have two immiscible liquids in a closed flask and keep everything still, the vapour pressure you measure will simply be the vapour pressure of the one which is floating on top.
		Agitated mixtures of immiscible liquids will boil at a temperature lower than the boiling point of either of the pure liquids.

		In the pictures, the students will be able to see how the oil sits on top of the water and how visible it is compared to the regular water in the ocean.
		This is called an immiscible solution, which is a substance that does not dissolve in each other.

		The goal of this research was to obtain stereocomplexes from PLA block copolymers containing highly immiscible blocks such as hydrophilic PEO and hydrophobic PEB.
		In the stereocomplex PEO was crystalline with a melting point at 45 °C, suggesting that it microphase separate from hydrophobic PEB to form individual domains.
		To obtain stereocomplexes from PLA block copolymers containing immiscible blocks, well-defined PEO-b-PLLA and PEB-b-PDLA diblock copolymers with a narrow molecular weight distribution (<1.16) were synthesized by ROP of the lactide monomers from PEO-OH and PEB-OH starting polymers using AlEt3 as the catalyst.

		The project assessed the feasibility of extracting and injecting the CO into the field to recover additional oil using an immiscible displacement process.
		Following an evaluation including core floods, compositional simulation, and facilities evaluation, the process was found both to have technical and economic promise in terms of improved oil recovery, and to result in reduction of both CO and methane emissions, the latter being an especially potent greenhouse gas.
