Carbon nanotubes displays

Carbon nanotubes displayed a higher specific surface area, which could explain the influence of the carbon nanotube morphology, with mainly an effect of the diameter. Long carbon nanotubes were extremely difficult to disperse in EVA, actually forming well-known associated bundles. 

Field emission displays are VFDs that use field emission cathodes as the electron source. The cathodes can be molybdenum microtips,33-35 carbon films,36,37 carbon nanotubes,38" 16 diamond tips,47 or other nanoscale-emitting materials.48 Niobium silicide applied as a protective layer on silicon tip field emission arrays has been claimed to improve the emission efficiency and stability.49 ZnO Zn is used in monochrome field emission device (FED) displays but its disadvantage is that it saturates at over 200 V.29... 

Various forms of carbon material such as graphite, diamond, carbon nanotubes (fibers), and amorphous carbon-containing, diamond-like carbon have been compared and analyzed for their potential application in the fields of flat panel displays and lighting elements.48... 

Fig. 9.1 Simulation snapshots of a DNA oligonucleotide (8 adenine bases) interacting with a (10,10) carbon nanotube at 0, 30, 100, and 500 ps. Water molecules are not displayed for clarity (Chaudhary et al., 2006. With permission from American Chemical Society) (See Color Plates)...

Fig. 12.3 Fabrication of the nanocomposite paper units for battery, (a) Schematic of the battery assembled by using nanocomposite film units. The nanocomposite unit comprises LiPF6 electrolyte and multiwalled carbon nanotube (MWNT) embedded inside cellulose paper. A thin extra layer of cellulose covers the top of the MWNT array. Ti/Au thin film deposited on the exposed MWNT acts as a current collector. In the battery, a thin Li electrode film is added onto the nanocomposite, (b) Cross-sectional SEM image of the nanocomposite paper showing MWNT protruding from the cel-lulose-RTIL ([bmlm] [Cl]) thin films (scale bar, 2pm). The schematic displays the partial exposure of MWNT. A supercapacitor is prepared by putting two sheets of nanocomposite paper together at the cellulose exposed side and using the MWNTs on the external surfaces as electrodes, (c) Photographs of the nanocomposite units demonstrating mechanical flexibility. Flat sheet (top), partially rolled (middle), and completely rolled up inside a capillary (bottom) are shown (See Color Plates)...

Ref. [14]. From one CD-R, it is possible to produce more than 50 pairs of such electrodes, which reduces the cost per electrode and suggests the disposability of the working electrode. A single-wall carbon nanotube (SWCNT) modified gold electrode was also employed in connection with CE microchips and displayed improved sensitivity and separation resolution compared to bare gold electrode, reflecting the electrocatalytic activity of SWCNT [102],... 

Process of chemical vapor deposition (CVD) is one of the most effective methods for preparation of flat emission cathodes. This method allows to produce different carbon structures on the cathode substrate. Depending on conditions of deposition, derivable carbon surface can be diamond-like films [1], amorphous graphite [2], various carbon constitutions, including carbon nanotubes [3], Investigation results of field emission properties produced cathodes have shown this is a promising technology for production Field Emission Display (FED). 

Flat-panel display technologies employing carbon nanotubes are demonstrated...
