Jun 1, 2015 · Carbon nanotubes (CNTs) have been viewed extensively under microscopic tools, such as the transmission electron microscope (TEM) or scanning electron microscope (SEM), to study the characteristics of the CNT cross-sectional shape and nanotube packing or bundling.

Sep 25, 2024 · With atomic resolution imaging, in situ transmission electron microscopy (TEM) has been a key technique to reveal the microstructure and dynamics of CNTs in real time. In this review, recent advances in the development of in situ TEM with different types of environmental reactors will be introduced.

Jun 1, 2018 · In this work, we utilize Joule heating to convert Pt-embedded amorphous carbon nanofiber (CNF) to multiwall carbon nanotube (CNT) in a transmission electron microscope (TEM). The transformation process of Pt-embedded amorphous CNF to multiwall CNT and nano-soldering process using Pt encapsulated CNT was investigated in TEM in detail.

Currently, the development of aberration-corrected TEM/STEMs, direct detection cameras, and the miniaturization of specimen holders have created new opportunities for in situ TEM.

Our research findings indicate that forming iron carbide (Fe3C) is a crucial transition phase for amorphous carbon transformation to CNTs. Notably, the iron catalyst generated the longest and...

Metal/carbon nanotubes (CNTs) have been attractive hybrid systems due to their high specific surface area and exceptional catalytic activity, but their challenging synthesis and dispersion...

Carbon nanotubes (CNT) were synthesized from a H2-CH4 mixture with W/Co-MgO catalyst by a catalytic chemical vapour deposition (CCVD) method. Different W/Co ratios were investigated. From...

Our analysis results provide strong evidence that the metallic catalyst remains in a liquid state during nanotube growth. The upward-growth pulling force of the CNT layer elongates the liquid nanoparticles, which are finally broken into two parts.
