Abstract: The paper presents the chemical composition and mineralogical distribution of the corrosion crust, more so the chemical composition and the texture of the metallic core on three silver coins dating from the seventeenth century, discovered in various tombs in the necropolis belonging to the former Stratenia Church from Iasi. These were examined by the corroboration of optical microscopy, electron microscopy coupled with X-ray diffraction (SEM-EDX) and the micro-FTIR techniques. The data allowed to establish the main alloy and of the evolutionary contexts during the laying period, based on the texture of the metallic core and on the layout of corrosion products.

Abstract: Our studies previously demonstrated that new bone formed around implants can be classified into 3 or 4 types based on tissue structure and composition. Results of the present study, using polarized light microscopy, and microscopic Fourier transform infrared spectroscopic imaging (micro-FT-IR) and micro-XRD to examine different areas in the peri-implant new bone, suggest differences in crystallinity (crystal size) between pre-existing bone and peri-implant new bone.
