Thin films of sol-gel derived Pt/alumina were prepared from a boehmite solution containing alumina-sec-butoxide and chloroplatinic acid. At 1100 °C, c-Al 2 O 3 phase was not present in the alumina sample but it remained in the Pt/alumina sample, suggesting that improved thermal stability of the c-Al

Porous hydroxyapatite (HAP) ceramics with different morphologies were fabricated by the freeze casting method. The morphologies of HAP ceramics were modified by adjusting the concentration of polyvinyl alcohol (PVA) additive in the HAP slurries. HAP ceramics without PVA additive were composed of non
