Autor: Atsutomo Nakamura, Kensuke Yasufuku, Yuho Furushima, Kazuaki Toyoura, K. Peter D. Lagerlöf, Katsuyuki Matsunaga
Publikováno v: Crystals, Vol 7, Iss 11, p 351 (2017)
Oxide materials have the potential to exhibit superior mechanical properties in terms of high yield point, high melting point, and high chemical stability. Despite this, they are not widely used as a structural material due to their brittle nature. H

Theoretical and Experimental Studies on the Ability of Intracrystalline Pores of β-La2(SO4)3 To Accommodate Various Gas Species with a Special Focus on Ammonia Insertion Behaviors
Autor: Tetsuya Uda, Naoyuki Hatada, Kunihiko Shizume, Kazuaki Toyoura, Hirotaka Tai
Publikováno v: ACS Applied Materials & Interfaces. 13:52793-52801
β-La2(SO4)3 is a microporous inorganic crystal with one-dimensional perforated pores where H2O molecules can be inserted. To evaluate the nature of the pores and extend the application range, we investigate the ability to accommodate various hydroge

Theoretical study on proton diffusivity in Y-doped BaZrO3 with realistic dopant configurations
Autor: Shusuke Kasamatsu, Tetsuya Uda, Takeo Fujii, Kazuaki Toyoura
Publikováno v: Physical Chemistry Chemical Physics. 23:5908-5918
We theoretically revisit the proton diffusivity in yttrium-doped barium zirconate (Y-doped BaZrO3) with realistic dopant configurations under processing conditions. In a recent study employing the replica exchange Monte Carlo method, the equilibrium

Reexamination of the phase diagram of the BaO-ZrO2-Y2O3 system: investigation of the presence of separate region in Y-doped BaZrO3 solid solution and the dissolution of Zr in Ba3Y4O9
Autor: Naoyuki Hatada, Tetsuya Uda, Donglin Han, Kazuaki Toyoura, Katsuhiro Ueno
Publikováno v: Journal of Solid State Electrochemistry. 24:1523-1538
Y-doped BaZrO3 (BZY) is a promising candidate for electrolytes in protonic ceramic fuel cells. To achieve the high proton conductivities of sintered electrolyte membranes, the poor sintering nature is one of the problems because of the high resistanc
