From Jonathan.Avaro at empa.ch Tue Oct 4 10:27:08 2022 From: Jonathan.Avaro at empa.ch (Avaro, Jonathan) Date: Tue, 4 Oct 2022 08:27:08 +0000 Subject: [Smam] Discussion cartilage Message-ID: Dear All, Thanks for the excellent discussion during today's SMAM meeting. I am attaching a paper on scanning SAXS on the bone cartilage interface; I think it is going in the same direction as what we have been talking about this morning and present some nice data analysis we could use. Thanks again, All the best, Jonathan ---------------------------------------------------------------------------- --- Jonathan Avaro Scientist ?

I hope to see all of you there! October 14, 15.00 Zoom: https://chalmers.zoom.us/j/64410417838 Password: 895648 Micro- and nano-scale structural quantification of shark mineralized cartilage Stuart R. Stock Dept. of Cell & Developmental Biology, Feinberg School of Medicine, & Simpson Querrey Inst., Northwestern Univ., Chicago, IL, USA The skeletons of elasmobranchs, which include sharks and rays, consist of cartilage (type 2 collagen). Some elasmobranch skeletal cartilage is mineralized with a bioapatite related to hydroxyapatite, and the centra (i.e., vertebral bodies) of sharks possess remarkable resistance to large in vivo strains exceeding 4%. It appears that these centra?s fracture resistance is related to a hierarchy of structures, and this talk focuses on the bioapatite micro- and nano-organization of the tissue. Studying these very different size scales requires different techniques, especially considering that structural gradients in centra of shark orders Carcharhiniformes and Lamniformes can span tens of millimeters. Results of lab microCT on entire centra provide a 3D quantitative picture of the macrostructure and of microstructure down to the 20 micrometer scale. In blocks cut from centra, synchrotron microCT reveals that the centra tissue consists of closely spaced, mineralized trabeculae whose 3D characteristics can only be measured with volume element sizes below one micrometer. Nanostructure plays an important role in functionality of mineralized tissue based on collagen-bioapatite composite material. High- energy, position-resolved diffraction and small angle scattering with monochromatic x-rays furnishes precise data on various quantities: from the former, bioapatite lattice parameters, nanoparticle dimensions and crystallographic texture; from the later, values of the collagen D-period and sharpness of texture. Finally, 3D mapping of texture in entire centra is performed with energy dispersive diffraction; the first results on in situ compressive loading of centra are covered briefly. Speculation on how these different components contribute to in vivo mechanical performance concludes the talk. ----------------------------- Marianne Liebi Adjunct Associate Professor Chalmers University of Technology, G?teborg (SE) Group Leader Paul Scherrer Insitut, Villigen (CH) Liebi Research Group -------------- next part -------------- An HTML attachment was scrubbed...

We discussed these today during the visit of Annalisa, Joan, and Stephanie. you might be interested show those to your students who are writing new proposals.

We have found a house located in the lake Geneva area which seems appropriate, and they've suggested 3 weeks which are still available in May/June next year. So, please fill out the following doodle so we can try to block a week before the next beamtime scheduling begins: https://doodle.com/meeting/participate/id/dNL9QJ2a For each week the place is available for arrival on Sunday night or Monday depending on travel plans etc., and departure on Friday, but we will discuss this in more detail later. For those who would like to check the place out, here is a link: https://www.groups.swiss/en/leisure/Chalet-la-Varlope-Pavillon-Blonay-9790 Thanks and have a nice day, Torne -------------- next part -------------- An HTML attachment was scrubbed...
