    Schell, Juliana; Kamba, Stanislav; Kachlík, Martin; Maca, Karel; Drahokoupil, Jan; Rano, B. Rahman; Gonçalves, Joo Nuno Santos; Dang, Thien Thanh; Costa, Angelo; Noll, Cornelia; Vianden, Reiner; Lupascu, Doru C. (AIP Publishing, 2019-12-01)
    Using time-differential perturbed angular correlation of gamma rays, we investigated the electric-field gradient of polycrystalline EuTiO3 and Eu2Ti2O7, with Hf-181(Ta-181) as a probe, following different thermal treatments. ...
  • Synthesis of high density sub-10 µm (Ba0.85Ca0.15) (Zr0.1Ti0.9)O3-xCeO2 lead-free ceramics using a twostep sintering technique 

    Bijalwan, Vijay; Tofel, Pavel (TAYLOR & FRANCIS LTD, 2019-10-29)
    (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3-xCeO2, (BCZTCe) lead-free piezoelectric ceramics were processed conventionally using a two-step sintering technique. The results suggest that two-step sintering is an effective technique to ...
