| Abstract Scope |
Frustules are the hierarchically structured glass skeletons of diatoms, optimized for strength and grown in a carbon-negative fashion. We grow diatoms scalably, to use their frustules for novel materials with light weight and high strength and toughness. We developed processing techniques to make the harvested frustules compatible with additive manufacturing techniques, which allows us to create materials with many levels of hierarchical organization, reaching from 50 nm to 10 cm. The obtained samples approach the structural complexity of natural hierarchical materials, enabling toughness enhancing failure mechanisms, and correspondingly, promising mechanical properties. Given their chemical inertness and high temperature stability, these materials are promising candidates for fully sustainable, multi-functional materials. |
