Study of new sheep bone and Zn/Ca ratio around TiAlV screw: PIXE–RBS analysis

Does surface anodisation of titanium implants change osseointegration and make their extraction from bone any easier?

“…The distal femur and proximal tibia (alternating between the right and left hind limb) were operated upon. The implant locations were chosen such that six sites were located in trabecular bone for histological evaluation and 10 in cortical bone with five samples each for mechanical testing and measurements of ion distribution (PIXE, published elsewhere [17]) ( Fig. 3).…”

Modification of Parylene film-coated glass with TiO2 nanoparticles and its photocatalytic properties

“…The penetration depth of TiO 2 NPs into the Parylene film was evaluated by the RBS method according to the previously described technique [26]. RBS is an analytical nuclear technique for determining quantitatively the depth profiles of an elemental concentration based on elastic collisions between ions and the atomic nucleus.…”

Atomic Spectrometry Update. Clinical and biological materials, foods and beverages

“…94 Accumulation of Pb and Zn at the calcification front hints that there may be involvement in osteoarthritis. New bone formation around TiAlV alloy bone screws was examined by Guibert et al 139 using PIXE and backscattering imaging. Depth profiles for Ca, Cu, Fe and Zn were determined and showed that new bone formed to a depth of 300-400 mm with a high Zn:Ca ratio and increased vascularization.…”
