Journal ArticleDOI
Capacitive mechanism of oxygen functional groups on carbon surface in supercapacitors
TL;DR: In this paper, the authors systematically analyzed the reasons for the increase of the capacity that promoted by oxygen functional groups in charge∕discharge cycling tests and the mechanism how the pseudocapacitance is provided by the oxygen functional group in the acid/alkaline aqueous electrolyte.
Journal ArticleDOI
Temperature- and magnetic-field-induced magnetization reversal in perovskite YFe0.5Cr0.5O3
Jinhua Mao,Yu Sui,Xingquan Zhang,Yantao Su,Xianjie Wang,Zhiguo Liu,Yi Wang,Ruibin Zhu,Yang Wang,Wanfa Liu,Jinke Tang +10 more
TL;DR: Perovskite YFe0.5Cr 0.5O3 exhibits magnetization reversal at low applied fields due to the competition between the single ion magnetic anisotropy and the antisymmetric Dzyaloshinsky-Moriya interaction as discussed by the authors.
Journal ArticleDOI
High temperature transport and thermoelectric properties of Ag-substituted Ca3Co4O9+δ system
TL;DR: In this article, the thermoelectric properties of polycrystalline Ca 3− x Ag x Co 4 O 9+ δ (0.3) samples were prepared by solid-state reaction method.
Journal ArticleDOI
Origin of colossal dielectric permittivity of rutile Ti0.9In0.05Nb0.05O2: single crystal and polycrystalline
Yongli Song,Xianjie Wang,Yu Sui,Ziyi Liu,Yu Zhang,Hongsheng Zhan,Bingqian Song,Zhiguo Liu,Zhe Lv,Lei Tao,Jinke Tang +10 more
TL;DR: Thedielectric behavior and impedance spectrum of the polycrystalline ceramic sample indicated that the internal barrier layer capacitor (IBLC) mode made a major contribution to the high ceramic dielectric permittivity, instead of the electron-pinned defect-dipoles.
Journal ArticleDOI
The contribution of doped-Al to the colossal permittivity properties of AlxNb0.03Ti0.97−xO2 rutile ceramics
Yongli Song,Xianjie Wang,Xingquan Zhang,Yu Sui,Yu Zhang,Zhiguo Liu,Zhe Lv,Yang Wang,Ping Xu,Bo Song +9 more
TL;DR: In this article, the authors investigated the dielectric properties of AlxNb0.03Ti0.97−xO2 (x = 0, 0.01, 0.,03 and 0.05) ceramics and found that the mechanism of massive permittivity (CP) in this material system and the effect of doping ions are still unclear.
