Amorphization and Directional Crystallization of Metals Confined in Carbon Nanotubes Investigated by in Situ Transmission Electron Microscopy

06-Jul-2015 | Dai-Ming Tang; Cui-Lan Ren; Ruitao Lv; Wan-Jing Yu; Peng-Xiang Hou; Ming-Sheng Wang; Xianlong Wei; Zhi Xu; Naoyuki K ..., Nano Letters, 2015

The hollow core of a carbon nanotube (CNT) provides a unique opportunity to explore the physics, chemistry, biology, and metallurgy of different materials confined in such nanospace. Here, we investigate the nonequilibrium metallurgical processes taking place inside CNTs by in situ transmission ...
