Ph: S0038-1098(97)10125-9 Measurement of the Elastic Modulus of a Multi-wall Boron Nitride Nanotube
نویسنده
چکیده
We have experimentally determined the elastic properties of an individual multi-wall boron nitride (BN) nanotube. From the thermal vibration amplitude of a cantilevered BN nanotube observed in a transmission electron microscope, we find the axial Young's modulus to be 1.22 ± 0.24 TPa, a value consistent with theoretical estimates. The observed Young's modulus exceeds that of all other known insulating fibers. Our elasticity results confirm that BN nanotubes are highly crystalline with very few defects. © 1998 Elsevier Science Ltd

Vibration Analysis of Timoshenko Beam reinforced with Boron-Nitride Nanotube on Elastic Bed
In this paper, free vibration analysis of a polymer-based nano-composite beam reinforced by boron-nitride nanotubes and subjected on elastic foundation, is studied. Smooth and defect-free nanotubes with uniform and directly- orientated in matrix are intended. Also, nanotubes’ distribution in the thickness direction of beam is regarded as a uniform distribution of the three different targeted on...

To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

متن کاملMolecular dynamics simulations of boron-nitride nanotubes embedded in amorphous Si-B-N
In this article, we examine the elastic properties of boron-nitride nanotubes, which are embedded in amorphous silicon-boron-nitride ceramics. We employ molecular dynamics simulations using the Parrinello-Rahman approach. To this end, all systems are modeled with a reactive many-body bond order potential due to Tersoff, which is able to describe covalent bonding accurately. We apply external st...
