Nanoscale atomic waveguides with suspended carbon nanotubes
We propose an experimentally viable setup for the realization of one-dimensional ultracold atom gases in a nanoscale magnetic waveguide formed by single doubly-clamped suspended carbon nanotubes. We show that all common decoherence and atom loss mechanisms are small guaranteeing a stable operation of the trap. Since the extremely large current densities in carbon nanotubes are spatially homogen...
متن کاملDeposition of carbon nanotubes in commonly used sample filter media
There is no single standard technique or methodology to characterize the size, structure, number, and chemical composition of airborne carbon nanotubes. Existing analytical instruments and analytical techniques for evaluating nanoparticle concentrations cannot simultaneously provide morphology, state of agglomeration, surface area, mass, size distribution and chemical composition data critical...
متن کاملNanoscale Vibrational Analysis of Single-walled Carbon Nanotubes
LLE Review, Volume 100 269 Introduction Since their discovery in the early 1990s by Iijima,1 carbon nanotubes have become the focus of intense interest by a vast number of scientists and engineers. The main reason behind such wide-ranging attention lies in their unique electrical,2 mechanical,3 thermal,3 and optical properties.4 Furthermore, from their size and structure, carbon nanotubes provi...
متن کاملNanoscale optical imaging of single-walled carbon nanotubes
In this contribution, we apply a microscopic technique that relies on the enhanced electric field near a sharp, laserirradiated metal tip that acts as a highly confined light source. The tip is used for the local excitation of the optical response of single-walled carbon nanotubes (SWNT) deposited on glass. We demonstrate photoluminescence and Raman imaging of the same SWNTs with a spatial reso...
متن کاملLow-friction nanoscale linear bearing realized from multiwall carbon nanotubes
We demonstrate the controlled and reversible telescopic extension of multiwall carbon nanotubes, thus realizing ultralow-friction nanoscale linear bearings and constant-force nanosprings. Measurements performed in situ on individual custom-engineered nanotubes inside a high-resolution transmission electron microscope demonstrated the anticipated van der Waals energy-based retraction force and e...
