xAg2O∙(100-x)∙[P2O5∙CaO] glass system with 0 x 5 mol% was prepared and investigated in order to evidence the structural changes induced by the silver ions in controlled addition. The samples local structure were investigated using X-ray diffractions, IR and Raman spectroscopy. The X-ray diffraction patterns consist in a broad line, typical for a vitreous system. The phosphate structural units of the network former revealed from FT-IR and Raman spectra are ultra-, meta-, pyro-and ortho- phosphate units. Both FT-IR and Raman spectra do not evidence directly the presence of silver structural units in the studied glasses. A continuously depolimerization process of these calcium phosphate glasses structure was evidenced by the Raman spectroscopy..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
