Coalescence of fullerene cages: Topology, energetics, and molecular dynamics simulation
Sequential atomic rearrangements leading to the coalescence of fullerene cages or tubes are derived by topological analysis. Qualitative reasoning assists the search for the minimum-energy path, which consists of a jump-to-contact formation of covalent bonds between the separate cages and the following ‘‘plastic flow’’ by exclusively Stone-Wales bond rotations. A connecting neck forms and grows...
متن کاملDynamic topology of fullerene coalescence.
Atomic rearrangements leading to the coalescence of fullerene cages are revealed by topological analysis. Paths found for nanotubes and C(60) consist exclusively of Stone-Wales bond rotations. Computed intermediate states show gradual evolution from separate clusters to completely fused coherent units. Molecular dynamics simulations follow the predicted routes, overcome the nucleation barrier, ...
متن کاملObservations of chemical reactions at the atomic scale: dynamics of metal-mediated fullerene coalescence and nanotube rupture.
Single-walled carbon nanotubes (SWNTs), which are graphitic tubular structures with single-atom-thick sidewalls and varying diameters, are effective containers for a wide variety of molecular species. They are particularly suitable for study by transmission electron microscopy (TEM). Chemical reactions between molecules inside nanotubes can be triggered by external stimuli (for example, the TEM...
متن کاملContinuum dynamics of elastocapillary coalescence and arrest
The surface-tension–driven coalescence of wet hair, nano-pillars and supported lamellae immersed in an evaporating liquid is eventually arrested elastically. To characterize this at a continuum level, we start from a discrete microscopic model of the process and derive a mesoscopic theory that couples the inhomogeneous dynamics of drying to the capillary forcing and elastic bending of the lamel...
متن کاملCharm elliptic flow from quark coalescence dynamics
From covariant transport theory, a significant ∼ 10% light quark elliptic flow at RHIC implies an elliptic flow of similar magnitude for charm quarks, at moderately large pT > 2.5 − 3 GeV. At lower transverse momenta, charm quark elliptic flow reduces progressively, reminiscent of the mass ordering pattern in ideal hydrodynamics. From the quark flows we predict the elliptic flow of D mesons at ...
