bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. in this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. the structure and bioactivity of these samples based on their interaction with simulated body fluid (sbf) have been determined. in-vitor, using the raman spect...

Piezoelectric materials are the group of smart materials which have been recently developed for biomedical applications, such as bone tissue engineering. These materials could provide electrical signals with no external source power making them effective for bone remodeling. Between various types of materials, BaTiO3 and CaTiO3 are nontoxic piezoelectric ceramics, which recently have been intro...

The apoC-III proteoform containing two sialic acid residues (apoC-III2) has different in vitro effects on lipid metabolism compared with asialylated (apoC-III0) or the most abundant monosialylated (apoC-III1) proteoforms. Cross-sectional and longitudinal associations between plasma apoC-III proteoforms (by mass spectrometric immunoassay) and plasma lipids were tested in two randomized clinical ...

The aim of the present research was to fabricate and study crystal structure and phase composition of Bi5FeTi3O15 (BTFO) ceramics exhibiting Aurivillius type structure. By means of simultaneous thermal analysis and X-ray diffraction analysis the process of synthesis of BTFO ceramics has been studied. Mixed oxide method followed by pressureless sintering was used for ceramics preparation. Three ...

Europium doped transparent lead fluorophosphate glass ceramics successfully were prepared with heat treatment of precourse glasses at temperature above glass transition (Tg). X-ray diffraction (XRD) experiment evidenced the formation of PbF2 nanocrystals in glassy matrix. The emission spectra investigation indicate that considerable amount of Eu3+ ions were trapped in crystalline phase, and the...
