The phrase "a sharp interface between" is correct and usable in written English.
It can be used to describe a clear and distinct separation or boundary between two entities, concepts, or systems.
Example: "There is a sharp interface between the software and hardware components, ensuring efficient communication."
Alternatives: "a clear boundary between" or "a distinct separation between".
The multilayers exhibit a sharp interface between dielectric and metal layers by spectroscopic ellipsometry analysis.
We consider the problem of a sharp interface between salt and fresh waters in an aquifer of spatially variable permeability.
The front tracking is incorporated via cut-cell mesh refinement to ensure a sharp interface between the fluids.
Obtained results evidenced a sharp interface between the coating and substrate in terms of the profile of chemical composition.
Replacing a sharp interface between LiFePO4 and FePO4 that has been shown to contain many additional line defects called "dislocations," the SSZ serves as a buffer, reducing the number of dislocations that would otherwise move with the electrochemical reaction front.
The results showed that the TiN/TaN coatings exhibited good modulation periods and a sharp interface between TiN and TaN layers and had cubic structure.
Due to the laminar flow, a sharp interface is maintained between the two streams.
Goldman elaborates: "[Houston is] a place where there's a very sharp interface between the human imprint on the land and the natural environment, a natural environment that's fairly fragile.
Due to the low deposition temperature of BFO, a compositional sharp interface between the FePt 001) bottom electrode and BFO layer is expected, which is important to both the development of BFO 001) texture and the FM/AFM interactions.
From the composition profile we can conclude, however, on an atomically sharp interface between PbS-core and a pure CdS-shell as was already reported for the PbX/CdX core/shell systems.
Under the assumption of a "sharp interface" and an equilibrium state between both fluids, analytical and numerical methods are proposed to calculate the discharge rate of the oil recovery plant and the location of the interface between both fluid components according to the Dupuit-Forscheimer approximation.
