ABSTRACT We have measured 21 adsorption isotherms for argon on single-walled carbon nanotubes produced by laser ablation. We explored temperatures between 40 and 153 K to obtain the coverage dependence of the isosteric heat of adsorption for films in the first and second layers. Our data are compared to results obtained in computer simulation studies and to data obtained in previous experimental investigations of this system.

    • "Several methods have been developed for the growth of carbon nanotubes (CNTs) including arc-discharge (Koshio et al. 2000), laser ablation (Krungleviciute et al. 2005; Saran et al. 2004), chemical vapor deposition (CVD) (Li et al. 2007; Mattia et al. 2006; Zheng et al. 2002), and plasma-enhanced chemical vapor deposition (PECVD) (Chen et al. 2007; Liu et al. 2007). Among these methods, CVD and PECVD allow the greatest control of the diameter, location, and density of the CNTs. "

    ABSTRACT: The nucleation of the nickel nanoparticles on substrates, a critical process in the growth of carbon nanotubes, has been modeled analytically using thermodynamic and statistical theories. It was hypothesized that during the initial stages of the annealing process smaller nanoparticles with the size of about 5nm form and, subsequently, randomly hop to make larger nanoparticles. The minimum and maximum diameter of the nickel nanoparticles can be obtained from the derived expressions. In addition, the size-dependent probability of forming the nanoparticles was examined at various temperatures and plasma power densities in chemical-vapor deposition and plasma-enhanced chemical-vapor deposition methods, respectively. The theoretical results presented agreed very well with experimental data.

    ABSTRACT: Micellles of poly(cyclohexyl metharylate)-block-poly(2-vinylpyridine) (PCMA-b-P2VP) block copolymer in methanol were used as nanoreactors to fabricate FeCl3 nanoparticles. Then the FeCl3-loaded micelles solution was used as an ink to print films with polydimethylsiloxane (PDMS) stamps, different morphologies of the FeCl3-loaded micellar films were left onto silicon substrates after printed. After removing the polymer by thermal decomposition, the left iron oxide cluster arrays on the substrate were used as catalysts for the growth of CNTs by the process of PECVD, where the CNTs uniformly distributed on the substrates according to the morphologies of patterned catalysts arrays. Moreover, with a pre-coating of aluminum oxide (Al2O3) layer onto silicon wafers, CNTs grew vertically onto the substrates with the catalyst nanoparticles, forming aligned and patterned structures.

    ABSTRACT: An isotherm quasi-discontinuity, or a near-vertical step, at 177 ยตTorr indicative of Kr condensation inside open single-walled carbon nanotubes (SWNT) has been observed at 77 K. The isotherm shows double adsorption-branch structure attributed to the existence of two endohedral phases of confined Kr. Three well-pronounced steps corresponding to the formation of various exohedral phases are present in the high-density (low-pressure) branch. The desorption branch exhibits three rounded steps assigned to higher order exohedral coverage.
