Material properties emerge from atomic-scale structure and processing. This simulation models how materials form, transform, and respond to conditions.
About This Simulation
Build a CVD nanotube growth model with catalyst particles.
Key Concepts
- Crystal Nucleation: New crystals form when atoms overcome an energy barrier to create stable nuclei. Classical Nucleation Theory describes this process quantitatively.
- Homogeneous vs Heterogeneous: Nucleation can occur uniformly in bulk (homogeneous, rare) or preferentially at surfaces/defects (heterogeneous, common).
- Grain Boundaries: Interfaces between differently-oriented crystal regions that strongly influence material properties.
- Phase Transformations: Changes in crystal structure driven by temperature, pressure, or composition changes.
Why It Matters
Materials science enables development of stronger, lighter, and more functional materials for technology.
How to Explore
- Adjust the sliders to modify simulation parameters and observe how the system responds
- Look for emergent patterns that arise from agent interactions
- Try extreme parameter values to find phase transitions and tipping points
- Compare the simulation behavior to real-world phenomena
