Strength of nanotubes , filaments and nanowires from sonication - induced scission ∗
We propose a simple model to describe the cavitation-induced breakage of mesoscale filaments during their sonication in solution. The model predicts a limiting length below which scission no longer occurs. This characteristic length is a function of the tensile strength and diameter of the filament, as well as the solvent viscosity and cavitation parameters. We show that the model predicts accu...
متن کاملKinetics of Carbon Nanotube scission under Sonication
A dispersion of individualised carbon nanotubes is commonly obtained by means of sonication. Under sonication bundles of nanotubes are debundled, a process known as exfoliation. During sonication small bubbles within a liquid are brought into oscillation by an acoustic field. Under certain conditions these oscillations can end in the violent collapse of the bubble. This disruptive process dispe...
متن کاملMechanics of carbon nanotube scission under sonication.
As-produced carbon nanotubes come in bundles that must be exfoliated for practical applications in nanocomposites. Sonication not only causes the exfoliation of nanotube bundles but also unwanted scission. An understanding of how precisely sonication induces the scission and exfoliation of nanotubes will help maximising the degree of exfoliation while minimising scission. We present a theoretic...
متن کاملOptical Vortex Induced Rotation of Silver Nanowires
Optical manipulation of metal nanowires offers the possibility to control the position, orientation, and associated motions of individual nanowires, particularly by utilizing their plasmonic properties. Here, we demonstrate that the orbital angular momentum of photons in Laguerre−Gauss (optical vortex) beams can induce rotation of single silver (Ag) nanowires with lengths of over 10 μm that are...
متن کاملSurface Plasmon Resonance-Induced Stiffening of Silver Nanowires
We report the results of a computational, atomistic electrodynamics study of the effects of electromagnetic waves on the mechanical properties, and specifically the Young's modulus of silver nanowires. We find that the Young's modulus of the nanowires is strongly dependent on the optical excitation energy, with a peak enhancement occurring at the localized surface plasmon resonance frequency. W...
