    pH-dependent absorbance of a centrifuged rhodamine B-TiO2 suspension, and a practical filtration method with minimized dye loss in a dye decoloration test

    Although the centrifugation of a rhodamine B (RhB)-TiO2 suspension cannot separate TiO2 particles completely, the UV/Vis absorbance of the residual TiO2 in the centrifuged suspension, under neutral and basic cond...

    Microstructural evolution of metatitanic acid with temperature and its photosensitization property

    Metatitanic acid (MTA) powder was heat-treated up to 800 °C in air, and the resultant evolutions of crystalline phase, specific surface area, and pore size were investigated. MTA loses its weight in two steps;...

    Visible-light photocatalytic activity of NH3-heat-treated Ta2O5 to decompose rhodamine B in aqueous solution

    Ta2O5 powder was heat treated in flowing NH3 at varying temperature for 2 h. When heat treated at 680–720 °C, nitrogen was doped to Ta2O5, but showed only a slight improvement of photocatalysis of rhodamine B dye...

    Thermophysical Properties of Ceramic Filler-Added BaO–ZnO–B2O3–P2O5 Glass Composites for Barrier Ribs of Plasma Display Panels

    The capability of BaO–ZnO–B2O3–P2O5 glass in hosting various ceramic fillers (up to 20 mass% of Al2O3, TiO2, and ZnO) has been investigated. All the investigated filler-added glasses have demonstrated a reasonabl...
