Summary
A new method generates 3D porous media with controlled properties. This allows for precise placement of phases, influencing macroscopic conductivity for advanced material design.
Area of Science:
- Materials Science
- Physics
- Chemical Engineering
Background:

- Parameter variation to control phase location (interfacial or within-phase).
- Analysis of interfacial phase shape (granular or lamellar) at low probabilities.
- Illustration of a third phase's influence on macroscopic conductivity.
Main Results:
- Successful generation of 3D multiphase porous media with fixed phase probabilities.
- Demonstration of locating specific phases at interfaces or within single phases.
