This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...

In this paper, kinetics of DC electrophoretic deposition EPD of carbon nanotubes CNTs is investigated. Carbon nanotubes suspended in pure ethanol with addition of magnesium nitrate was used as deposition media. The effect of main EPD parameters such as deposition time, applied voltage and the CNT concentration on deposit yield was investigated. The variation of current density vs. time and the ...

CNT/Au/SnO(2) nanotubes have been synthesized through homogeneous coating of Au and SnO(2) nanocrystals on carbon nanotubes (CNTs) and applied in a room-temperature CO gas sensor.

Poly(3-hydroxybutyrate) (PHB) is a natural, linear, thermoplastic polyester synthesized by microorganisms as intracellular carbon reserves and ion sinks in response to limited nutrient availability and imposed stress conditions. The PHB has become one of the most interesting biomaterials for application in tissue engineering due to its excellent biodegradability and biocompatibility. Nanocompos...

The spillover mechanism of molecular hydrogen on carbon nanotubes in the presence of catalytically active platinum clusters was critically and systematically investigated by using density-functional theory. Our simulation model includes a Pt4 cluster for the catalyst nanoparticle and curved and planar circumcoronene for two exemplary single-walled carbon nanotubes (CNT), the (10,10) CNT and one...

Horizontally aligned, dense carbon nanotubes (HADCNTs) in the form of CNT cantilevers/bridges were grown from selected trench sidewalls in silicon substrate by chemical vapor deposition (CVD). The as-grown CNT cantilevers/bridges are packed with multiwalled carbon nanotubes (MWCNTs) with a linear density of about 10 CNTs µm(-1). The excellent horizontal alignment of these CNTs is mainly ascribe...

Carbon nanotubes (CNTs) are attractive as nanosize structural elements from which devices can be constructed by bottom-up fabrication. A CNT is a macromolecule of carbon and is made by rolling a sheet of graphite into a cylindrical shape. CNTs exhibit excellent electrical properties that include current densities exceeding 109 A/cm2 and ballistic transport along the tube. Because of these facto...

This letter describes the use of vertically aligned carbon nanotubes (CNT)-based arrays with estimated 2-nm thick cobalt (Co) nanoparticles deposited inside individual tubes to unravel the possibility of using the unique templates for ultra-high-density low-energy 3-D nano-magneto-electronic devices. The presence of oriented 2-nm thick Co layers within individual nanotubes in the CNT-based 3-D ...

in this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (cnt) are investigated. three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) cnts were chosen as the models and the different orientations of so2 molecule relative to the cnt axis were considered. the b3lyp functional within the 6-31g(d) basis...
