Neutron plus X-ray Tomography of Bio-structures
Neutron and X-ray tomography provide different, and highly complementary information. Notably, in biomaterials neutron imaging allows the study of the hydrogen content and hydrogen-rich phases and their spatial distribution, for example in bones and cartilages. Additionally, neutrons have minimal impact on the biological materials making it ideal for operando studies, where multiple subsequent tomographies are acquired while the sample evolves, for example under mechanical load. Finally, the low opacity of metals to neutrons allows the study of metallic objects such as implants, virtually artifact-free. All this can be combined with simultaneous X-rays which provide a unique insight in the structural distribution and density variations. In recent times the facility has achieved record neutron tomographic resolution (e.g., https://doi.org/10.1364/OE.448932) and its potential for imaging of biomaterials at high resolution is virtually unexplored. Also its combined use with X-rays offers a vast, untapped potential, for example in examining bone healing around metallic implants under different types of treatment (e.g., https://doi.org/10.1088/1361-6560/ac02d4).
We seek a highly motivated postdoctoral researcher to develop research in bio-mechanical materials at the structural level on NeXT and help us push the boundaries of high resolution imaging for biomaterials and explore the applicability of neutron imaging for the study of their micro-structure. The work will be based at the Institut Laue Langevin and specifically at the Neutron and X-ray Tomograph NeXT-Grenoble. The project will have good access to state-of-the-art facilities within the medical, natural science and bio engineering faculties.
