## Description

This MCP server provides specialized computational tools for surface science. It uses the Owens-Wendt and Fowkes models to determine the total surface energy and its dispersive and polar components from contact angle measurements. Users can calculate the work of adhesion and the spreading coefficient for specific liquid-solid pairs, and categorize the resulting wettability regime. Key tools include `calculate_surface_energy` for component breakdown, `calculate_adhesion_metrics` for adhesion strength, and `analyze_wettability_regime` for behavior classification.

## Tools

### analyze_wettability_regime
Categorizes the wettability behavior of a liquid-solid pair

### calculate_surface_energy
Determines the total surface energy and its component breakdown using the OWRK/Fowkes models

### calculate_adhesion_metrics
Calculates the work of adhesion and the spreading coefficient for a specific liquid on a known surface

### validate_measurement_consistency
Checks if the provided contact angle measurements and surface tension components are physically consistent with the OWRK model

## Prompt Examples

**Prompt:** 
```

## Frequently Asked Questions

**What models are used for surface energy calculation?**
The server implements the Owens-Wendt-Rabel-Kaelble (OWRK) and Fowkes models to solve for dispersive and polar components.

**How many liquids are required for surface energy determination?**
At least two liquids with known surface tension components are required to solve the OWRK equations via `calculate_surface_energy`.

**Can I check if my measurements are physically consistent?**
Yes, the `validate_measurement_consistency` tool checks if your contact angles and surface tension components align with the OWRK model.
