nanotechnology

(nă″nō-tĕk-nŏl′ŏ-jē) [L. nanus, dwarf, + Gr. technē, art, + logos, word, reason]
The scientific study and engineering of chemical or biological objects measuring between 1 and 1000 nanometers. Objects this small are about the size of atoms or small molecules. “Wet” nanotechnology is the manipulation of organic or biological compounds in solution. “Dry” nanotechnology is the engineering of objects on silicon or carbon surfaces, such as those used in computing.

nanotechnology

The application of the science of manipulation at an atomic level. The practical applications of the ability to move single atoms so as to construct molecules, materials, structures and even functioning machines at an atomic level. Nanotechnology is currently at a germinal stage but is expected to have extensive applications in medicine. See also MAGNETIC NANOPARTICLES.

In this research activity, we have used carbon nanotube layers (with high thermal diffusivity and conductivity) as an excellent medium for paraffin (Octadecan in powder form) to design an innovative and efficient solar water heater.
Ab-initio analysis has been performed for determining the structural stability and electronic properties of single walled Mn doped GaN nanotubes. With the highest binding energy 4Mn doped (3, 3) GaN nanotube have been defended as the most stable structure amongst all others taken into consideration.
A shift of 4 kHz is measured upon retraction indicating that during retraction the nanotube is put into tension.
Loos acknowledges that "the main problem we have is to disperse the nanotubes. If we try to compare the properties of carbon fiber with CNTs, many people would prefer carbon fibers right now." Nevertheless, he says, nanotubes can improve anti-fatigue properties better than other fillers.
SWeNT's biggest customers over time have been in the R&D field, and like other nanotube manufacturers, SWeNT has allied with a major materials distributor and development partner Sigma-Aldrich (St.
"The ions distribute themselves throughout the nanotube film,"EeSalvatierra added.
Shahsavari said nanotube ice could find use in molecular machines or as nanoscale capillaries, or foster ways to deliver a few molecules of water or sequestered drugs to targeted cells, like a nanoscale syringe.
Combining the advantages of carbon nanotube lines with lightweight, good mechanical properties and electrical and chemical stability [12], we also designed carbon nanotube lines/silicone polymer of the artificial skin tactile sensor based on mesh models.
Furthermore, the Raman spectra (Figure 3) for the carbon nanotubes/graphene composites and [Co.sub.3][O.sub.4]/carbon nanotubes/graphene composites have three same peaks positioned at 1355 [cm.sup.-1] (D), 1583 [cm.sup.-1] (G), and 2679 [cm.sup.-1] (2D) which can be assigned to carbon nanotubes and graphene; however, the additional peak at 667 [cm.sup.-1] in the Raman spectrum for [Co.sub.3][O.sub.4]/carbon nanotubes/graphene composites can be attributed to [Co.sub.3][O.sub.4] which is in good agreement with the previous literatures [5, 8].
Fujitsu Laboratories has now developed a process for manufacturing carbon nanotubes, a material known for its high thermal conductivity in a cylindrical structure, and in which the combination of process temperature and pressure is precisely controlled to grow dense, uniform arrays of perpendicularly oriented carbon nanotubes.
