Mechanics of atoms and fullerenes in single - walled carbon nanotubes . II . Oscillatory behaviour
The discovery of carbon nanotubes and C60 fullerenes has created an enormous impact on possible new nanomechanical devices. Owing to their unique mechanical and electronic properties, such as low weight, high strength, flexibility and thermal stability, carbon nanotubes andC60 fullerenes are of considerable interest to researchers frommany scientific areas. One aspect that has attracted much at...
متن کاملMolecular motion of endohedral fullerenes in single-walled carbon nanotubes.
Spherical carbon cages of fullerene molecules interact by van der Waals forces to form close-packed arrangements in the solid state, such as the face-centered cubic lattice formed by C60 at room temperature. [1] Owing to the low directionality and low energy of the interfullerene interactions neutral fullerene molecules (such as C60) are freely rotating in the crystal at room temperature. Contr...
متن کاملMechanics of atoms and fullerenes in single - walled carbon nanotubes . I . Acceptance and suction energies
Owing to their unusual properties, carbon nanostructures such as nanotubes and fullerenes have caused many new nanomechanical devices to be proposed. One such application is that of nanoscale oscillators which operate in the gigahertz range, the so-called gigahertz oscillators. Such devices have potential applications as ultrafast optical filters and nanoantennae.While there are difficulties in...
متن کاملYoung s Modulus of Single and Double Walled Carbon Nanocones Using Finite Element Method(TECHNICAL NOTE)
In this paper a three-dimensional finite element (FE) model of carbon nanocones (CNCs) is proposed and used for obtaining Young\'s modulus of CNCs. In this model, stretching and bending forces between carbon atoms are simulated using truss elements in ANSYS software. Then the model is subjected to the tension and by obtaining the stiffness of the CNC and using elasticity theory, Young’s modulus...
متن کاملFunctionalised endohedral fullerenes in single-walled carbon nanotubes.
Atomically thin carbon nanotubes serve as transparent-test tubes for individual molecules of functionalised endohedral fullerenes. Aberration-corrected transmission electron microscopy reveals the complex dynamic behaviour of these molecules at the atomic level, and it sheds light on the mechanism of their encapsulation into nanotubes.
