Extended Data Fig. 4: In situ compression tests of single HAP nanoparticles.
From: A natural impact-resistant bicontinuous composite nanoparticle coating
In situ compression tests of single HAP nanoparticles. a–d, HAP nanoparticle before and after compression tests, indicating particle breakage. Five different nanoparticles were tested. Similar particle breakage was noticed. e, Load versus displacement curves of different tests. The breakage of particles and energy dissipation events are marked with back arrows. The total energy dissipation during compression is calculated from the integration of the force-displacement curves.
