Super strong nanoindentors for biomedical applications based on the bamboo-like nanotubes

Abstract

The results of quantum-chemical analysis of elastic and strength properties of the bamboo-like tube are presented in this paper. For the first time the configuration of the thinnest stable bamboo-like tube was established. The bamboo-like nanotube breaking point is established to be under compression of 11GPa. Configuration of the nanoindentor based on symmetric and streamlined tip of the tube (15,15), presented in this work, provides perfect interaction between the nanoindentor tip and the tissue because tip has no sharp protruding pieces.

Partitioned carbon nanotubes as perspective nanomaterial for energy conversion

“…The objects of investigation in this work were (15,15) partitioned carbon nanotubes due to the fact that these nanotubes are stable partitioned carbon nanotubes of the smallest diameter [11]. Partitioned carbon nanotubes were modeled by connection of the fullerene cap (bridge) to the inner surface of the nanotube by the chemical bonds.…”

“…Investigations of the electronic properties of carbon partitioned carbon nanotubes (CBNTs) were performed by the tight binding method [11]. Translation vector was introduced to create the infinite CBNTs (Fig.2) [14].…”

“…The aim of this work is to develop new technology of the partitioned carbon nanotubes synthesis as well as the theoretical investigation of the ionization potential and energy gap for the infinite partitioned carbon nanotubes in relation to the distance between bridges. In the current work the theoretical investigations of the partitioned carbon nanotubes were carried out by means of the empirical method and molecular dynamics method using REBO potential [11]. Electronic properties of the infinite partitioned carbon nanotubes were calculated by means of the quantum chemical tight-binding method [11].…”
