The aim of this study was to evaluate the antibacterial properties of oyster, hard clam, and sea urchin shell powders as a result of calcination. After subjection to calcination at 1050 °C for 2 h, and as identified by FTIR and XRD spectra, the structures of oyster, hard clam, and sea urchin shell powders were mainly transformed into calcium oxide, with slight amounts of calcium hydroxide. Metal content...
In the present study, Ag/SiO2–TiO2 thin films on ceramic tiles with glazed surface were successfully prepared by a liquid phase deposition method (LPD) at a low temperature. The Ag/SiO2–TiO2 thin films obtained were homogenous, well adhered and colored by interference of reflected light. The films were characterized by scanning electron microscopy and X-ray diffraction. From these analysis data, it...
