immiscible

The property of two liquids that do not mix, with respect to each other.

interface

Region where two things meet. In a mixture of oil and water, we refer to the places where the oil and water meet as the oil-water interface.

interfacial tension (Y)

Defined as the rate of change of the free energy with respect to change in surface area at a constant T,V and Number of molecules of each component present.
Y*dS = work that must be done to increase the surface by dS keeping the volume fixed.

in vivo

(relating to a biological process). Occuring or made to occur within a living organism or natural setting. Opposite to in vitro - which means made to occur in a laboratory vessel or other controlled experimental environment rather than a natural setting.

in vitro
