Equilibrium of [Si]/(SiO2) in Carbothermic Selective Reduction of Titanium Concentrate Ore for the Preparation of Titanium Oxycarbide
Xiao, Jiusan; Wang, Qi; Jiang, Bo; Zhu, Hongmin (Journal article; Peer reviewed, 2018)Carbothermic selective reduction of titanium concentrate ore for the preparation of titanium oxycarbide was presented and SiO2 was found to be partly reduced during the process. The equilibrium relationship between Si ... -
High interfacial charge storage capability of carbonaceous cathodes for Mg batteries
Wang, Lu; Jiang, Bo; Vullum, Per Erik; Svensson, Ann Mari; Erbe, Andreas; Selbach, Sverre Magnus; Xu, Huailiang; Vullum-Bruer, Fride (Journal article; Peer reviewed, 2018)A rechargeable Mg battery where the capacity mainly originates from reversible reactions occurring at the electrode/electrolyte interface efficiently avoids the challenge of sluggish Mg intercalation encountered in ... -
Local and average structure of Mn- and La-substituted BiFeO3
Jiang, Bo; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2017)The local and average structure of solid solutions of the multiferroic perovskite BiFeO3 is investigated by synchrotron X-ray diffraction (XRD) and electron density functional theory (DFT) calculations. The average ... -
Local structural coupling of A- and B-site disorder in perovskite bismuth-based piezoelectrics
Jiang, Bo; Lin, De-Ye; Grande, Tor; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2019)The local and average structure of (1-x)Bi0.5K0.5TiO3-xBiFeO3 (BKT-xBFO, x = 0.25 and 0.5) solid solutions are studied by synchrotron X-ray total scattering from ambient to 773 K. Pair distribution functions (PDFs) demonstrate ... -
Local Structure of Disordered Bi0.5K0.5TiO3 Investigated by Pair Distribution Function Analysis and First-Principles Calculations
Jiang, Bo; Grande, Tor; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2017)We investigate A-site cation ordering in the ferroelectric perovskite Bi0.5K0.5TiO3 (BKT) by density functional theory (DFT) calculations and synchrotron X-ray total scattering. Using BKT as a prototypical lead-free ... -
Metallic octahedral CoSe2 threaded by N-doped carbon nanotubes: A flexible framework for high-performance potassium-ion batteries
Yu, Qiyao; Jiang, Bo; Hu, Jun; Lao, Cheng-Yen; Gao, Yunzhi; Li, Peihao; Liu, Zhiwei; Suo, Guoquan; He, Donglin; Wang, Wei (Alex); Yin, Geping (Journal article; Peer reviewed, 2018)Due to the abundant and low‐cost K resources, the exploration of suitable materials for potassium‐ion batteries (KIBs) is advancing as a promising alternative to lithium‐ion batteries. However, the large‐sized and ... -
Oxidation of Liquid Silicon in Air Atmospheres Containing Water Vapor
Ma, Yan; Jiang, Bo; Moosavi-Khoonsari, Elmira; Andersson, Stefan; Opila, Elizabeth J.; Tranell, Gabriella (Peer reviewed; Journal article, 2019)The oxidation of silicon (Si) has been extensively investigated over the past 50 years. Yet, an understanding of the mechanism and rate of liquid Si oxidation in atmospheres containing water vapor, is lacking. The effect ... -
Pistachio‐Shuck‐Like MoSe2/C Core/Shell Nanostructures for High‐Performance Potassium‐Ion Storage
Wang, Wei; Jiang, Bo; Qian, Chang; Lv, Fan; Feng, Jianrui; Zhou, Jinhui; Wang, Kai; Yang, Chao; Yang, Yong; Guo, Shaojun (Journal article; Peer reviewed, 2018)Potassium‐ion batteries (KIBs) have recently attracted intensive attention because of the abundant potassium resources and their low cost and high safety. However, the major challenge faced by KIBs lies in the lack of ... -
Structural Disorder and Coherence across the Phase Transitions of Lead-Free Piezoelectric Bi0.5K0.5TiO3
Jiang, Bo; Ræder, Trygve Magnus; Lin, De-Ye; Grande, Tor; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2018)Relaxor ferroelectrics exhibit superior properties for converting mechanical energy into electrical energy, and vice versa, but the structural disorder hampers an understanding of structure–property relationships and impedes ...
