This chapter discusses about the behavior of Carbon Nanotube (CNT) different structures which can be used as interconnect in Very Large Scale (VLSI) circuits in nanoscale regime. Also interconnect challenges in VLSI circuits which lead to use CNT as interconnect instead of Cu, is reviewed. CNTs are classified into three main types including Single-walled Carbon Nanotube (SWCNT), CNT Bundle, and...

Carbon nanotubes focus the attention of many scientists because of their huge potential of industrial applications, but there is a paucity of information on the toxicological properties of this material. The aim of this experimental study was to characterize the biological reactivity of purified multi-wall carbon nanotubes in the rat lung and in vitro. Multi-wall carbon nanotubes (CNT) or groun...

Carbon nanotubes CNT was modified on the surface of glassy carbon electrode (GCE) using mechanical method to prepare working electrode CNT/GCE and CNT/Li+/GCE were used in cyclic voltammetry analysis. The nanostructured electrodes showed individual voltammetric of Mn2+ two reduction peaks at +800 and +100 mV. The reduction current of Mn2+ on CNT/Li+/GCE was largely influenced by low concentrati...

Copyright © Korean Carbon Society http://carbonlett.org Abstract The use of carbon nanotubes (CNTs) as a reinforcing material in a polymer matrix has increased in various industries. In this study, the flexural behavior of CNT-modified epoxy/ basalt (CNT/epoxy/basalt) composites is investigated. The effects of CNT modification with silane on the flexural properties of CNT/epoxy/basalt composite...

A post-growth chemical vapor deposition (CVD) treatment was used to tune the compressive mechanical properties of carbon nanotube (CNT) arrays. Millimeter tall CNT arrays with low compressive resilience were changed to a foam-like material with high compressive strength and almost complete recovery upon unloading. The foam was tuned to provide a range of compressive properties for various appli...

Carbon nanotube (CNT) and graphene sheet have shown promising due to their unique mechanical, electrical and thermal properties as well as plus light weight. CNT-graphene network is an interesting structure that obtained in experimental studies and can be used in many engineering disciplines. For this aim, understanding mechanical behavior of the CNT-graphene combination is necessary. In the pr...

In order to explore availability of carbon nanotube (CNT)-based positive temperature coefficient (PTC) thermistors in practical application, we prepared carbon nanotube (CNT) filled high density polyethylene (HDPE) composites by using conventional melt-mixing methods, and investigated their PTC effects in details. The CNT-based thermistors exhibit much larger hold current and higher hold voltag...
