The NiTi alloy system has fueled significant interest for its Shape Memory and Pseudoelastic effects.The transformation temperature of the NiTi alloy family is unfortunately confined below 100 °C thus its application temperatures are limited.CoNiGa alloys were found to posses shape memory properties at elevated temperatures which make them promising contenders for high temperature shape memory...

22. Pr2NiO4+d structure, valence states and lattice dynamics investigated by synchrotron radiation.

Oxides, exhibiting high oxygen ion conductivity, have gained considerable interest for their applications in Solid Oxide Fuel Cells (SOFCs). However, still today high operation temperatures of about 1000 °C are needed for SOFCs, requiring huge problems of mechanical and chemical stability. Unfortunately, a decrease in the temperature reduces activity of the solid electrolyte and reactivity of...

18. High Oxygen Mobility in Rare Earth Doped Ceria Compounds at Low Temperatures

Ms Ozden CELIKBILEK (ESRF Grenoble)
