Threading through Macrocycles Enhances the Performance of Carbon Nanotubes as Polymer Fillers
In this work, we study the reinforcement of polymers by mechanically interlocked derivatives of single-walled carbon nanotubes (SWNTs). We compare the mechanical properties of fibers made of polymers and of composites with pristine SWNTs, mechanically interlocked derivatives of SWNTs (MINTs), and the corresponding supramolecular models. Improvements of both Young's modulus and tensile strength ...
متن کاملCarbon Nanotubes as Optical Antennae
Light scattering from an array of aligned multiwall carbon nanotubes (MWCNTs) has previously been investigated, and shown to be consistent with that from an array of antennae. Two basic antenna effects have been demonstrated: 1) the polarization effect, which suppresses the response of an antenna when the electric field of the incoming radiation is polarized perpendicular to the dipole antenna ...
متن کاملLooking beyond carbon nanotubes: polypeptide nanotubes as alternatives?
Since the discovery of CNT by Iijima, Nature 354, 56 (1991), CNT's have surged to the forefront as a versatile nanostructured material in nanoelectronic applications. Polypeptides nanotubular structures with tunable properties offer a challenging alternative to CNT. Earlier experimental studies on L-Alanyl-L-Valine (AV) and L-Valyl-L-Alanine (VA) have demonstrated their potential as novel porou...
متن کاملMultiwall carbon nanotubes as quantum dots.
We have measured the differential conductance of individual multiwall carbon nanotubes. Coulomb blockade and energy level quantization are observed. The electron levels are nearly fourfold degenerate (including spin) and their evolution in magnetic field (Zeeman splitting) agrees with a g factor of 2. In zero magnetic field the sequential filling of states evolves with spin S according to S = 0...
متن کاملCarbon nanotubes as heat dissipaters in microelectronics
We review our recent modelling work of carbon nanotubes as potential candidates for heat dissipation in microelectronics cooling. In the first part, we analyze the impact of nanotube defects on its thermal transport properties. In the second part, we investigate the loss of thermal properties of nanotubes in presence of an interface with various substances, including air and water. Comparison w...
