Abstract: A method for preparing multi-wall carbon nanotubes comprising atomizing a precursor solution comprising an aromatic hydrocarbon and a carrier gas. The mixture is then injected through an ultrasonic atomization system to form atomized precursor droplets. Then by injecting the atomized precursor droplets from the top of a vertical chemical vapor deposition reactor, the droplets can then react with a reaction gas in the reactor vessel to form a film that adsorbs to a growth surface in the reactor vessel. Layer by layer multi-wall carbon nanotubes are formed. This method is repeated to form layers of the multi-wall carbon nanotubes. The nanotubes formed have an outer diameter of 10 nm-51 nm and a length to diameter aspect ratio of 7200-13200.

Abstract: A process for making an iron oxide impregnated carbon nanotube membrane. In this template-free and binder-free process, iron oxide nanoparticles are homogeneously dispersed onto the surface of carbon nanotubes by wet impregnation. The amount of iron oxide nanoparticles loaded on the carbon nanotubes range from 0.25-80% by weight per total weight of the doped carbon nanotubes. The iron oxide doped carbon nanotubes are then pressed to forma carbon nanotube disc which is then sintered at high temperatures to form a mixed matrix membrane of iron oxide nanoparticles homogeneously dispersed across a carbon nanotube matrix. Methods of characterizing porosity, hydrophilicity and fouling potential of the carbon nanotube membrane are also described.

Abstract: A nanofluid composed of a base fluid and a solid nanocomposite particle, where the solid nanocomposite particle consists of a carbon nanotube and a metal oxide nanoparticle selected from the group consisting of Fe2O3, Al2O3, and CuO. The metal oxide nanoparticle is affixed inside of or to the outer surface of the carbon nanotube, and the solid nanocomposite particle is homogeneously dispersed in the base fluid. The heat transfer and specific heat capacity properties of the nanofluid are measured using differential scanning calorimetry and heat exchanger experiments with different nanocomposite concentrations and different metal oxide percent loadings.
