Hard data resolves decades-old mystery of how certain zeolites form

Silicon-oxygen nanoparticles aggregate to form zeolites.

Silicon-oxygen nanoparticles aggregate to form zeolites, capturing other atoms and molecules in the process. The resulting minerals have regularly-shaped, intricate pore and channel systems throughout their structures.

Laboratory-grown zeolites appear to form in a hierarchical, steep-bystep fashion.

Laboratory-grown zeolites appear to form in a hierarchical, steep-by-step fashion with silicon-oxygen nanoparticles forming first. Those particles then aggregate into larger, more complex structures, incorporating other atoms and molecules while still leaving substantial pores and tunnels.
