Nano-plasticity of thin single-wall carbon nanotubes under uniaxial compression is investigated through generalized tight-binding molecular dynamics (GTBMD) and ab-initio electronic structure methods. A novel mechanism of nano-plasticity of carbon nanotubes under uniaxial compression is observed in which bonding geometry collapses from a graphitic (sp 2) to a localized diamond like (sp 3) recon...

Carbon nanomaterials (CNMs) are increasingly employed in nanomedicine as carriers for intracellular transport of drugs, imaging probes, and therapeutics agents, thanks to their unique optical and physicochemical properties. However, a better understanding about the effects of CNMs on a vertebrate model at the whole animal level is required. In this study, we compare the toxicity of oxidized car...

We describe the nanofabrication study of self-aligned electrodes on suspended multiwalled carbon nanotube structures. When metal is deposited on a suspended multiwalled carbon nanotube structure, the nanotube acts as an evaporation mask, resulting in the formation of discontinuous electrodes. The metal deposits on the nanotubes are removed with lift-off. Using Al sacrificial layers, it was poss...

Carbon nanotubes (CNTs) and carbon nanotube field effect transistors (CNFETs) have demonstrated extraordinary properties and are widely expected to be the building blocks of next generation VLSI circuits. This chapter presents (1) the first purely CNT and CNFET based nanoarchitecture, (2) an adaptive configuration methodology for nanoelectronic design based on the CNT nano-architecture, and (3)...

Owning to their unparalleled sensitivity resolution, nanomechanical resonators have excellent capabilities in design of nano-sensors for gas detection. The current challenge is to develop newdesigns of the resonators for differentiating distinct gas atoms with a recognizably high sensitivity. In this work, the characteristics of impulse wave propagation in carbon nanotube-based sensors are inve...

Differential Analog Viterbi Decoding (DAVD) for Forward-Error-Correction (FEC) is used in channel coding for digital communications. The use of analog circuits to reduce the size and power consumption of channel decoders such as Viterbi decoders has been an active area of research over the recent years. In this paper, differential analog Viterbi decoder architecture is proposed and implemented ...

High speed Full-Adder (FA) module is an important element in designing high performance arithmetic circuits. In this paper, I propose a high speed multiple-valued logic FA module. The proposed FA is designed and constructed with the use of 3 capacitors and 14 transistors, wh e r e t h e t r a n s i s t or s a r e c o n s t r u c t e d b y carbon nano-tube field effect transistor (CNFET) technol...
