Journal ArticleDOI
The origin of refractory minerals in comet 81P/Wild 2
Miaofang Chi,Miaofang Chi,Hope A. Ishii,Steven B. Simon,John P. Bradley,Zu Rong Dai,D. Joswiak,Nigel D. Browning,Graciela Matrajt +8 more
TL;DR: In this paper, the authors examined the refractory Ti-bearing minerals in the calcium-, aluminum-rich inclusion (CAI) Inti, recovered from the comet 81P/Wild 2 sample, using analytical (scanning) transmission electron microscopy (STEM) methods including imaging, nanodiffraction, energy-dispersive spectroscopy (EDX) and electron energy loss spectrograms.
Journal ArticleDOI
Structural variability of edge dislocations in a SrTiO3 low-angle [001] tilt grain boundary
James P. Buban,Miaofang Chi,Miaofang Chi,Daniel J. Masiel,John P. Bradley,Bin Jiang,Henning Stahlberg,Nigel D. Browning,Nigel D. Browning +8 more
TL;DR: Using a spherical aberration (Cs)-corrected scanning transmission electron microscopy (STEM) and electron energy-loss spectroscopy (EELS), the authors investigated a 6° low-angle tilt grain boundary in SrTiO3.
Journal ArticleDOI
Improving Corrosion Resistance of AZ31B Magnesium Alloy via a Conversion Coating Produced by a Protic Ammonium-Phosphate Ionic Liquid
Hassan H. Elsentriecy,Hassan H. Elsentriecy,Jun Qu,Huimin Luo,Harry M. Meyer,Cheng Ma,Miaofang Chi +6 more
TL;DR: In this article, a conversion coating using a protic ammonium-phosphate ionic liquid (IL) was introduced to improve corrosion resistance for the IL treatment at 300°C (IL_300C).
Journal ArticleDOI
Direct in Situ Observation and Analysis of the Formation of Palladium Nanocrystals with High-Index Facets
Wenpei Gao,Yusheng Hou,Zachary D. Hood,Xue Wang,Karren L. More,Ruqian Wu,Younan Xia,Younan Xia,Xiaoqing Pan,Miaofang Chi +9 more
TL;DR: This study reveals that concave-structured Pd NPs can be formed by the cointroduction of surface capping agents and halogen ions, and reveals the detailed atomic-scale kinetics during their formation, providing insight for future predictive synthesis.
Journal ArticleDOI
Evidence for and mitigation of the encapsulation of gold nanoparticles within silica supports upon high-temperature treatment of Au/SiO2 catalysts: Implication to catalyst deactivation
TL;DR: In this article, the authors investigated the effect of high-temperature treatment on the textural and structural changes of a mesoporous SiO 2 (SBA-15) and an amorphous Cab-O-Sil as the support.
