In the area of Li ion cells/Li conductors highlights include the synthesis of TiO2–B nanowires by Armstrong et al., and the observation of high Li ion conductivity in the garnet-related materials Li5La3(Nb/Ta)2O12 by Thangadurai et al.
In the area of oxide ion conductors, a key highlight was the structural study by Leon-Reina et al. of apatite-type La9.33+x(Si/Ge)6O26+3x/2 confirming the presence of interstitial oxygens in the site previously predicted by modelling studies.
In the area of superconductivity, a highlight has been the observation by Ekimov et al. of superconductivity at ≈ 4 K in boron doped diamond synthesised at high temperature and pressure.
