摘要:
Our recent results on the local structures around a specified atom in several kinds of energy-related materials, i.e., Mg doped UO2 as a new type of nuclear fuel, (La1-xMx)2Zr2O7 (M = Nd or Ce) as a promising ceramic matrix for fixation of TRU elements, and La2(Zr1-xYx)2O7, Ba(Ce1-xYx)O3 and Sr(Ce0.95Yb0.05)O3 as a protonic conductor, determined by EXAFS using synchrotron radiation are summarized in relation to their anticipated functional properties.
