High resolution X-ray tensor tomography to study the spiral nanostructure of narwhal tusk ...
Narwhals are mysterious animals whose tusk has a unique spiral structure with highly anisotropic mechanical properties. We hypothesize that the orientation of the biological nanostructure reflects the spiral macro-structure, which defines their mechanical properties. Previous experiments showed impo...

Narwhals are mysterious animals whose tusk has a unique spiral structure with highly anisotropic mechanical properties.
