In this paper at first a brief review of carbon nanotubes (CNTs) is given and then an extensive survey of CNTFET (carbon nanotube field effect transistor) based logic circuits are discussed with the most recently reported CNTFET logic circuits. Keywords— MOSFETs, technology scaling, CNTFETs, carbon nanotubes (CNT), chiriality.

Multi-walled carbon nanotube (MWCNT) film has been fabricated onto Pt-patterned alumina substrates using the chemical vapor deposition method for NH(3) gas sensing applications. The MWCNT-based sensor is sensitive to NH(3) gas at room temperature. Nanoclusters of Co catalysts have been sputtered on the surface of the MWCNT film to enhance gas sensitivity with respect to unfunctionalized CNT fil...

We examine at the DFT level of theory the topology of side wall functionalization of the (5,5)metallic single-wall carbon nanotube (CNT) with carbenes (>CX(2)) and its effect on electronic properties of the system. It is demonstrated that specific substructures/topology known to stabilize functionalized fullerene molecules can play the same role in CNTs, as well. Upon deepening of functionaliza...

The importance of the incorporation nanomaterials in concrete has emerged as a promising research interest due to outstanding functionalized properties materials at that size level. This study aims investigate engineering and durability incorporated with hybrid nanomaterials. In this study, influence carbon nanotube (CNT) on microstructure, mechanical, corrosion characteristics nano-clay-based ...

carbon nanotubes have unique properties like high stability, high surface to mass ratio and so on which make them suitable for medicinal purpose applications. treatment of cancer by organoplatinum agents like cisplatin has become unresponsive in most cases due to low distribution of drug in biological fluids, inability of drug to cross cellular membranes and low stability in biological environm...

In this paper we study a system composed by carbon nanotube (CNT) and bundle of carbon nanotube (BuCNT) interacting with a specific fatty acid as molecular probe. Full system is represented by open nanotube (or nanotubes) and the linoleic acid (LA) relaxing due the interaction with CNT and BuCNT. The LA has in his form an asymmetric shape with COOH termination provoking a close BuCNT interactio...

Cancer has arisen to be of the most prominent health care issues across the world in recent years. Doctors have used physiological intervention as well as chemical and radioactive therapeutics to treat cancer thus far. As an alternative to current methods, gene delivery systems with high efficiency, specificity, and safety that can reduce side effects such as necrosis of tissue are under develo...
