Effect of lattice volume and strain on the conductivity of BaCeY-oxide ceramic proton conductors
Qianli Chen, Artur Braun, Songhak Yoon +2
In-situ electrochemical impedance spectroscopy was used to study the effect of lattice volume and strain on the proton conductivity of the yttrium-doped barium cerate proton conduc…
The effect of compressive strain on the Raman modes of the dry and hydrated BaCe0.8Y0.2O3 proton conductor
Qianli Chen, Tzu-Wen Huang, Maria Baldini +7
The BaCe0.8Y0.2O3-δ proton conductor under hydration and under compressive strain has been analyzed with high pressure Raman spectroscopy and high pressure x-ray diffraction. The p…
High temperature oxygen NEXAFS valence band spectra and conductivity of LaFe3/4Ni1/4O3 from 300 K to 773 K
Artur Braun, Selma Erat, Ahmad K. Ariffin +4
LaFe3/4Ni1/4O3 was subjected to oxygen near edge x-ray absorption fine structure (NEXAFS) spectroscopy for 300 K < T < 773 K. The spectra show in the pre-edge a small hole doped pe…
Evolution of structural properties of iron oxide nano particles during temperature treatment from 250°C - 900°C: X-ray diffraction and Fe K-shell pre-edge X-ray absorption study
Debajeet K. Bora, Artur Braun, Selma Erat +3
Iron oxide nano particles with nominal Fe2O3 stoichiometry were synthesized by a wet, soft chemical method with the heat treatment temperatures from 250°C to 900°C in air. The vari…
Proton diffusivity in the BaZr0.9Y0.1O3-δ proton conductor
Artur Braun, Sophie Duval, Peter Ried +7
The thermally activated proton diffusion in BaZr0.9Y0.1O3-δ was studied with electrochemical impedance spectroscopy (IS) and quasi-elastic neutron scattering (QENS) in the temperat…
Quantitative model for anisotropy and reorientation thickness of the magnetic moment in thin epitaxially strained metal films
Artur Braun
A quantitative mathematical model for the critical thickness of strained epitaxial metal films is presented, at which the magnetic moment experiences a reorientation from in-plane…
