COLLECTIVE DYNAMICS OF A NANO-FLUID: FULLERENE, C₆₀

Abstract

Collective dynamics of a strongly correlated nano-fluid of fullerenes, C 60 having number density 0.945 particles/nm3 at 1850 K has been predicted using the sphericalized inter-fullerene interaction and the self-consistent microscopic theory of fluids. The dynamical structure factors have been computed to yield much different dispersion relation of the collective excitations from that of the Lennard–Jones type fluid. The wave-vector dependent longitudinal viscosity of the nano-fluid has also been reported.

Particle-resolved dynamics during multilayer growth ofC60

“…However, besides size and internal structure there is another important difference between C 60 molecules and atoms: The range of the effective, i.e. angle-averaged, attractive interaction between two C 60 molecules is much smaller than the usual van-der Waals interaction (decaying as r −6 , r being the separation) between atoms 30,31 . This difference between the pair potentials is illustrated in Fig.…”

Fullerene-water nanofluid confined in graphene nanochannel

“…20 Especially, fullerenes can be seen as natural hydrophobic ball bearing to reduce the friction and wear, and to improve the carrying capacity. Although several computational and theoretical studies have been reported in the literature on various aspects of solid and liquid phases of fullerene, 21,22 there are no investigations reporting on flow and boundary slip properties of fullerene-water NFs.…”

Ability of Fullerene to Accumulate Hydrogen

“…Currently, the Lennard-Jones potential (LJ-potential) is used to describe the interaction of a fullerene with different particles: to comprehensively study fullerene motion in open carbon nanocones [10], to describe the dynamics of the C 60 -graphite collision [11] to study encapsulation of C 60 in single-walled carbon tubes [12], to determine the dynamic factors of fullerene nanofluids [13], and also a LJ-potential additive is used to generate both translational and anisotropic-rotational motion of each fullerene particle [14]. The use of the LJ-potential and the Coulomb potential allows to analyze movement of fullerene structures within an ensemble of particles of the same kind, as well as movement of potassium ions inside a fullerene "sphere" [15].…”
