Journal ArticleDOI
All-Scale Hierarchical Structure Contributing to Ultralow Thermal Conductivity of Zintl Phase CaAg 0.2 Zn 0.4 Sb.
Jie Chen,Jie Chen,Wenhua Xue,Wenhua Xue,Chen Chen,Hongxing Li,Canying Cai,Qian Zhang,Yumei Wang +8 more
TL;DR: The microstructure is investigated by spherical aberration‐corrected electron microscopy on an atomic scale, which reveals an all‐scale hierarchical structure that can scatter the phonons in a wide frequency range and contributes to the decrease of lattice thermal conductivity in aWide temperature range.
Journal ArticleDOI
Hollow Ag/carbon microporous spheres with high catalytic activity based on a bio-inspiration polydopamine reaction platform
TL;DR: In this article, the hollow Ag/carbon spheres, with a uniform shell thickness of 30 nm and a high Ag loading, showed high catalytic activity for the reduction of 4-nitrophenol by NaBH4 to 4-aminophenol.
Journal ArticleDOI
Half-Heusler thermoelectric materials: NMR studies
Yefan Tian,Nader Ghassemi,Wuyang Ren,Wuyang Ren,Hangtian Zhu,Shan Li,Shan Li,Qian Zhang,Zhiming Wang,Zhifeng Ren,Joseph H. Ross +10 more
TL;DR: In this paper, a series of half-Heusler semiconductors, including NbCoSn, ZrCoSb, TaFeSb and NbFeSsb, were used for nuclear magnetic resonance measurements and density functional theory (DFT) calculations.
Journal ArticleDOI
Facile synthesis, microstructure and photophysical properties of core-shell nanostructured (SiCN)/BN nanocomposites.
TL;DR: The results suggest that the SiCN/BN nanocomposites act as semiconductor displaying superior width photoluminescence at wavelengths spanning the visible to near-infrared (NIR) spectral range (400‒700 nm), owing to the heterojunction of the interface between the SiC(N) nanowire core and the BN nanosheet shell.
Journal ArticleDOI
Thermal expansion of Y2W3O12/Al metal matrix composites
TL;DR: In this paper, the authors used squeeze casting to fabricate a 60 vol.-% Y2W3O12/Al composite, which showed that negative thermal expansion was not reacted with Al due to advantage of squeeze casting fabrication.
