20.500.12556/RUL-168042 Integrating attenuated total reflectance–fourier transform infrared spectroscopy and multidetector computed tomography for analysis of heat-induced changes in bone Abstract: archaeological records and can also be subjects of forensic investigations. Heat exposure causes specific changes to the physical and chemical characteristics of these remains, offer ing valuable insights into their taphonomic history. This research combines the commonly used ATR-FTIR (Attenuated Total Reflectance–Fourier Transform Infrared) spectroscopy with the rarely utilised density measurements obtained from Multidetector CT (Computed Tomography) to investigate changes in defleshed bovine cortical bone exposed to different temperatures for varying durations. The inclusion of density measurements is significant because Multidetector CT analysis is non-destructive and can be valuable when remains cannot be removed from their burial context (e.g., urn) or cannot be damaged. The results indicate complex changes in both organic and inorganic components, affecting crystallinity and density. Lower temperatures primarily affect organic matter, while higher temperatures induce significant changes in the mineral lattice and phase transitions. The transforma tion from β-tricalcium phosphate to α-tricalcium phosphate at high temperatures likely impacts the bone’s crystallinity and density. Bone density measured by CT scans provided additional information that complemented the interpretations of FTIR spectroscopy. While CT scans offer important data for planning non-destructive analyses of remains, they present only one layer of information. Therefore, CT scans need to be combined with other techniques to provide comprehensive interpretations of the changes occurring in the bone. Further research is needed on density measurements and other potentially non-destructive analyses to fully unlock the potential of Multidetector CT analyses. skeletal remains ATR-FTIR spectroscopy Multidetector CT FTIR indices density cremation skelet skelentni ostanki ATR-FTIR spektroskopija multidetektor CT FTIR indeksi gostota kremacija true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-26 15:11:30 2025-03-26 15:11:32 2025-03-27 03:56:21 0000-00-00 00:00:00 2025 0 0 Str. 1-15 No. 742 Vol. 18 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 572:902 1996-1944 230353411 https://www.mdpi.com/1996-1944/18/4/742/pdf?version=1739181157 1 2feebafe-0a4b-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201028 Leskovar_T_2025_Integrating_attenuated.pdf Leskovar_T_2025_Integrating_attenuated.pdf 1 067FDD7BCB80197F2B2B893310E5F409 38e4ceaaff182d8c88d91e494ca0a5d103f68b7f0756f06d05d2e11887a142d4 1995bee5-0a54-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201030 Filozofska fakulteta Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
