  • RPI SCOREC - Technical Reports
    Letters Volume 87 Pages 6 9 Editor American Institute of Physics Abstract Recent experiments demonstrated very low percolation thresholds for carbon nanotube composites signified by steep increases in electrical conductivity at very low nanotube loadings By contrast thermal transport measurements even on the same samples showed no signature of the percolation threshold These contrasting behaviors are particularly intriguing considering that both transport processes are described by the same continuum equation

    that chain diffusivity is enhanced relative to its bulk value when polymer particle interactions are repulsive and is reduced when polymer particle interactions are strongly attractive In both cases chain diffusivity assumes its bulk value when the chain center of mass is about one radius of gyration Rg away from the particle surface This behavior echoes the behavior of polymer melts confined between two flat surfaces except in the limit

    to External Atomic Collisions Year 2005 Journal NanoLetters Volume 5 Pages 263 268 Editor American Chemical Society Abstract The mechanical response of single walled and multiwalled carbon nanotubes to a series of external Ar atom impacts is examined with classical molecular dynamics simulations The extent to which the carbon nanotubes deform in the direction perpendicular to their axis is found to depend on the amount of momentum transferred during the

    fibers have been proposed as a route for surpassing the performance of heat transfer liquids currently available Recent experiments on nanofluids have indicated significant increases in thermal conductivity compared with liquids without nanoparticles or larger particles strong temperature dependence of thermal conductivity and significant increases in critical heat flux in boiling heat transfer Some of the experimental results are controversial e g the extent of thermal conductivity enhancement sometimes greatly

    classical molecular dynamics simulations of the thermal expansion of C60 molecules and 10 10 single walled carbon nanotubes The key result reported in a recent Letter 2 is that both C60 and nanotubes exhibit zero thermal expansion coefficient at T 0 that with increasing temperature first becomes negative and then turns positive at higher temperatures They noted that this temperature dependence was in agreement with the experimentally observed in plane

    shear although detrimental to high stiff ness and strength could result in very high mechanical damping which is an important attribute in many commercial applications We previously reported5 evidence of damping in nanocomposites by measuring the modal response at resonance of cantilevered beams with embedded nanocomposite fi lms Here we carry out direct shear testing of epoxy thin fi lms containing dense packing of multiwalled carbon nanotube fi llers and

  • RPI SCOREC - Technical Reports
    Letter Kumar et al 1 introduced a model for heat conduction in nanofluids liquid suspensions of nanosized particles that was capable of describing experimental results on thermal conductivity of nanofluids The model was built in two steps In the first step a static problem immobile particles was considered in which the total heat flux was a sum of heat conduction by the liquid and particles In the second step the
