How Divalent Ions Drive Nanocrystals Into Stunning Spherical Shapes
University of Amsterdam researchers reveal how subtle ion shifts in viscous salt solutions trigger nanocrystals to self-assemble into sea-urchin-like spherulites.
Key Takeaways
- University of Amsterdam researchers pinpoint divalent metal ions as the architects of stunning spherical nanocrystal assemblies
- High viscosity during crystallization enables massive prenucleation cluster formation that seeds radially organized spheres
- The discovery, published in Communications Chemistry, could unlock engineered nanomaterials with high surface-to-volume ratios
