N2 - Multiwalled carbon nanotubes (MWCNTs) are widely investigated for their excellent properties and are finding promising applications in nano/bio-technology such as nano-thermometer, SPM probe, and field emission tip, to name just a few. They have also been employed as the bases for combining with other materials in many electronic, mechanical, biological and energy-related applications. Through recent years, we have purchased an ultrahigh-vacuum transmission electron microscope (UHV-TEM) and incorporated a couple of e-beam evaporators and a homemade scanning tunneling microscope (STM). This unique instrument allows us perform various in situ experiments on a single nanostructure. In this report, I will present our studies on in-situ growth of Ag clusters on carbon nanotubes [1], manipulating CNTs with e-beam irradiation and current heating, peeling off the CNT's inner shells, fabricating an atom balance [2], capillary absorption of molten Ag nanodroplets into a CNT [3], etc. All these dynamic phenomena and properties have been observed and measured within a nanometer scale.
