Visualizing Under-Coordinated Surface Atoms on 3D Nanoporous Gold Catalysts.
Pan Liu,Pan Liu,Pengfei Guan,Akihiko Hirata,Ling Zhang,Luyang Chen,Yuren Wen,Yi Ding,Takeshi Fujita,Jonah Erlebacher,Mingwei Chen,Mingwei Chen +11 more
TL;DR: The intricate 3D geometric shape and surface atomic structure of nanoporous gold catalysts are investigated using aberration-corrected scanning transmission electron microscopy in combination with discrete tomography, offering atomic insights into the catalysis of the nanoporous catalyst.
Journal ArticleDOI
Nucleation of shear bands in amorphous alloys
TL;DR: The operation of a bimodal distribution of the first pop-in loads that are associated with different shear band nucleation sites that operate at different stress levels below the glass transition temperature, Tg.
Journal ArticleDOI
Coral-Shaped MoS2 Decorated with Graphene Quantum Dots Performing as a Highly Active Electrocatalyst for Hydrogen Evolution Reaction.
Bangjun Guo,Ke Yu,Honglin Li,Ruijuan Qi,Yuanyuan Zhang,Haili Song,Zheng Tang,Ziqiang Zhu,Mingwei Chen,Mingwei Chen +9 more
TL;DR: The present work provides a potential way to design two-dimensional hydrogen evolution reaction (HER) electrocatalysts through controlling the shape and modulating the electric conductivity and suggests that the coral MoS2@GQD is a zero-gap material.
Journal ArticleDOI
High-energy-density nonaqueous MnO2@nanoporous gold based supercapacitors
Luyang Chen,Jianli Kang,Ying Hou,Pan Liu,Takeshi Fujita,Akihiko Hirata,Mingwei Chen,Mingwei Chen +7 more
TL;DR: In this article, the capacitive performances of MnO2 in nonaqueous electrolytes are dramatically improved by nanoporous gold electrodes, which give rise to low internal resistance, good ionic contact and thus enhanced redox reactions for high specific capacitance of NMO2.
Journal ArticleDOI
Microstructural characterization of boron-rich boron carbide
Kelvin Y. Xie,Vladislav Domnich,Lukasz Farbaniec,Bin Chen,Kanak Kuwelkar,Luoning Ma,James W. McCauley,Richard A. Haber,K.T. Ramesh,Mingwei Chen,Mingwei Chen,Kevin J. Hemker +11 more
TL;DR: In this paper, detailed micro-structural characterization was carried out on three hot-pressed B-rich boron carbide samples, and the results showed that the hardness of bors carbide is reduced by bors substitution, suggesting that excess bors preferentially substitutes for carbon atoms in the B 11 C icosahedra.
