Journal ArticleDOI
Neutron diffraction study of magnetism in van der Waals layered MnBi2n Te3n+1
Lei Ding,Chaowei Hu,Erxi Feng,Chenyang Jiang,Iurii Kibalin,Arsen Gukasov,Miaofang Chi,Ni Ni,Huibo Cao +8 more
TL;DR: In this article, the authors compared the crystal and magnetic structures of two-dimensional van der Waals MnBi2n Te3n+1 (n = 1, 2, 3, 4) compounds and discussed the effects of chemical composition on their magnetism.
Journal ArticleDOI
Facile Synthesis of Pt Icosahedral Nanocrystals with Controllable Sizes for the Evaluation of Size‐Dependent Activity toward Oxygen Reduction
Ming Zhao,Joseph Holder,Zitao Chen,Zitao Chen,Minghao Xie,Zhenming Cao,Miaofang Chi,Younan Xia,Younan Xia +8 more
TL;DR: In this paper, the authors reported a facile route to the quick synthesis of Pt icosahedral nanocrystals with tunable sizes by simply varying the amount of the precursor.
Journal ArticleDOI
Measuring and directing charge transfer in heterogenous catalysts
Michael J. Zachman,Victor Fung,Felipe Polo-Garzon,Shaokui Cao,Jisue Moon,Zhennan Huang,De-en Jiang,Zili Wu,Miaofang Chi +8 more
TL;DR: In this article , a robust scanning transmission electron microscopy (STEM) method was used to simultaneously visualize the atomic-scale structure and sub-nanometer-scale charge distribution in heterogeneous catalysts using a model Au-catalyst/SrTiO 3 -support system.
Journal ArticleDOI
Enhanced alcohol production over binary Mo/Co carbide catalysts in syngas conversion
Arun S. Asundi,Adam S. Hoffman,Miaofang Chi,Sindhu S. Nathan,Alexey Boubnov,Jiyun Hong,Simon R. Bare,Stacey F. Bent +7 more
TL;DR: In this paper, a combination of advanced electron microscopy and X-ray diffraction is applied to show that the binary Mo/Co carbide catalyst forms uniformly mixed amorphous nanoparticles.
Journal ArticleDOI
Triosmium Clusters on a Support: Determination of Structure by X‐ray Absorption Spectroscopy and High‐Resolution Microscopy
S Mehraeen,Apoorva Kulkarni,Miaofang Chi,Bryan W. Reed,Norihiko L. Okamoto,Nigel D. Browning,Nigel D. Browning,Bruce C. Gates +7 more
TL;DR: The structures of small, robust metal clusters on a solid support were determined by a combination of spectroscopic and microscopic methods: extended X-ray absorption fine structure (EXAFS) spectroscopy, scanning transmission electron microscopy (STEM), and aberration-corrected STEM.
