The final section of the volume contains three complementary review articles on carbon nanoparticles. The first by Y. Saito reviews the state of knowledge about carbon cages encapsulating metal and carbide phases. The structure of onion-like graphite particles, the spherical analog of the cylindrical carbon nanotubes, is reviewed by D. Ugarte, the dominant researcher in this area. The volume concludes with a review of metal-coated fullerenes by T. P. Martin and co-workers, who pioneered studies on this topic. [Pg.193]

E.l You have become very excited about the possibilities of nanotechnology, especially the creation of fibers one atom wide. Suppose you were able to string together 1.00 mole of silver atoms, which have a radius of 144 pm, by encapsulating them in carbon nanotubes (see Box 14.1). How long could the fiber extend ... [Pg.68]

Recently, TsHs has been encapsulated within single-walled (SWNTs) and multiwalled carbon nanotubes (MWNTs) with internal diameters of 0.8-8 nm. It was shown that the best results were obtained when the internal diameters (1.4—1.5 nm for SWNTs and 1.0-3.0 nm for MWNTs) slightly exceeded the diameter of TsHs (1.2 nm). T8H8 was introduced in the gas phase and reacted with the nanotubes through van der Waals interactions. ... [Pg.28]

CNTs can also be encapsulated with DNA molecules. As shown in Fig. 9.1, a DNA molecule could be spontaneously inserted into a SWNT in a water solution via molecular dynamics simulation (Gao et al., 2003). The van der Waals and hydrophobic forces were very key factors for the insertion process, with the former playing a more dominant role in the course of DNA entering into the hole of CNT. Experiment also confirmed that Pt-labeled DNA molecules can be encapsulated into multi-walled carbon nanotubes in water solution at 400 K and 3 Bar as shown in Fig. 9.2 (Cui et al., 2004). The CNTs filled with DNA molecules have potential in applications such as gene delivery system, and electronic sequencing, nanomotor, etc. [Pg.183]

Encapsulation of different entities inside the CNT channel stands alone as an alternative noncovalent functionalization approach. Many studies on the filling of carbon nanotubes with ions or molecules focus on how the presence of these fillers affects the physical properties of the tubes. From a different point of view, confinement of materials inside the cylindrical structure could be regarded as a way to protect such materials from the external environment, with the tubes acting as a nanoreactor or a nanotransporter. It is fascinating to envision specific reactions between molecules occurring inside the aromatic cylindrical framework, tailored by CNT characteristic parameters such as diameter, affinity towards specific molecules, etc. [Pg.60]

In this work, Pradhan et al. demonstrated the encapsulation of crystalline Fe404 nanoparticles into the uniform carbon nanotubes by the MOCVD technique using ferrocene and that the size and number of such nanoparticles can be easily controlled by changing the MOCVD temperature or its period. At a proper MOCVD condition, Fe404 nanocrystals could be introduced into all of the nanotubes to different degrees, and more than 20% of the total volume of the tube hollow was filled with the nanoparticles. [Pg.567]

Encapsulation of other material into carbon nanotubes would also open up a possibility for the applications to electrodevices. By applying the template method, perfect encapsulation of other material into carbon nanotubes became possible. No foreign material was observed on the outer surface of carbon nanotubes. The metal-filled uniform carbon nanotubes thus prepared can be regarded as a novel onedimensional composite, which could have a variety of potential applications (e.g novel catalyst for Pt metal-filled nanotubes, and magnetic nanodevice for Fe304-filled nanotubes). Furthermore, the template method enables selective chemical modification of the inner surface of carbon nanotubes. With this technique, carbon... [Pg.570]

An other interesting strategy is the modification of the surface of the electrodes with multiwalled carbon nanotubes (MWNTs) or single-walled carbon nanotubes (SWNTs) [13,32]. The MWNTs are grown on the electrodes covered with a nickel catalyst film by plasma-enhanced chemical vapour deposition and encapsulated in Si02 dielectrics with only the end exposed at the surface to form an inlaid nanoelectrode array [13]. In the other case, commercial SWNTs are deposited on SPE surface by evaporation [32], The carbon nanotubes are functionalised with ssDNA probes by covalent attachment. This kind of modification shows a very efficient hybridisation and, moreover, the carbon nanotubes improve the analytical signal. [Pg.607]

From the structural studies given in this article, it is evident that the charge density study by the MEM/Rietveld method using SR powder diffraction data is powerful for determination of the endohedral nature of metallofullerenes. There is no doubt the structural information provided greatly contributes to progress in research of endofullerenes as well as endofullerene peapod, which is the met-allofullerene-encapsulating carbon nanotube. [Pg.82]
