Electric-current-induced structural changes in a suspended multiwall carbon nanotube (MWCNT) were observed through situ transmission electron microscopy. The bias voltage and electric current measured simultaneously as the MWCNT was imaged. passage of excessive led to breakdown surface subsequent layer-by-layer removal broken outermost shell via sublimation atoms. accompanied by discrete decrea...

The mechanical properties of polymer composites, reinforced with silica-coated multiwall carbon nanotubes (MWNTs), have been studied using the nanoindentation technique. The hardness and the Young's modulus have been found to increase strongly with the increasing content of these nanotubes in the polymer matrix. Similar experiments conducted on thin films containing MWNTs, but without a silica ...

Subtle changes in the structure of nanoparticles influence their surface tension and corresponding interaction with cells and proteins. Here, the interaction of the single wall carbon nanotube (SWCNT) and multiwall carbon nanotube (MWCNT) with different surface tension with tau protein was evaluated using a variety of techniques including far and near circular dichroism, fluorescence spectrosco...
