  • Diatoms are uni-cellular algae that form an exterior silica shell. These shells are porous and display symmetry across several length scales.

    Diatoms are uni-cellular algae that form an exterior silica shell. These shells are porous and display symmetry across several length scales.
  • The honeycomb sandwich plate cross-section of the silica shell allows the diatom to maintain high strength while keeping weight low. Combining this architecture with a silica-organic composite as the constituent material gives the diatom shell the greatest strength-to-weight ratio of all previously reported natural biological materials.
