# Nanoparticle cluster builder

This interactive tool generates atomic coordinates for mono- and bimetallic nanoparticles, including cuboctahedral, icosahedral, spherical, and core-shell configurations.

The tool executes client-side via WebAssembly. Generated structures can be downloaded in standard crystallographic and simulation formats (XYZ, CIF, POSCAR).

## Capabilities

1. **Geometry selection**: Generate Wulff constructions, spherical cuts, or shell-by-shell regular geometric polyhedra.
2. **Core-shell partitioning**: Define core and shell compositions (e.g. Au core with Ag shell) and adjust radial boundaries.
3. **Lattice adjustment**: Control bulk lattice constants and surface relaxations.
4. **Export**: Export configurations directly for LAMMPS molecular dynamics runs or FEFF EXAFS calculations.
