2. 1. Bone structure characterisation using neutron scattering techniques

   Author : Elin Törnquist; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomechanics; neutron tomography; x-ray tomography; small-angle neutron scattering SANS ; small-angle x-ray scattering SAXS ; Experimental mechanics; implant integration; tomography; nanoscale; microscale; mechanical properties;

   Abstract : Bones have unique mechanical properties that originate from their main constituents: mineral, in the form of hydroxyapatite (HAp) crystals, and collagen type-I. The stiffness of the HAp mineral combined with the flexibility of collagen, and their intricate hierarchical arrangement from the smallest individual building blocks to the organ level, result in a composite tissue with a remarkable ability to withstand complex loading scenarios.

4. 2. Quantification of local lattice distortions in refractory high-entropy alloys by scattering-based techniques

   Author : Yao Hu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory high-entropy alloys; X-ray diffraction; local lattice distortion; pair distribution function; neutron scattering; total scattering;

   Abstract : The increasing demand for advanced structural materials for use in extreme conditions, particularly including the aerospace applications, has promoted the development of refractory high-entropy alloys (RHEAs). A deeper understanding of the interaction between microstructure and properties is essential to overcome the scientific challenges associated with these alloys. READ MORE
