Competition between hydrogen bonding and electric field in single-file transport of water in carbon nanotubes
hydrogen bonding and electric field single-file transport carbon nanotubes
<
2011/9/15
Recent studies have shown the possibility of water transport across carbon nanotubes, even in the case of nanotubes with small diameter (0.822 nm). In this case, water shows subcontinuum transport fol...
Spin-dependent electronic hybridization in a rope of carbon nanotubes
Spin-dependent electronic hybridization carbon nanotubes
<
2010/11/24
We demonstrate single electron addition to different strands of a carbon nanotube rope. Anticrossings of anomalous conductance peaks occur in quantum transport measurements through the parallel quantu...
Helical modes in carbon nanotubes generated by strong electric fields
Helical modes carbon nanotubes generated
<
2010/11/23
Helical modes, conducting opposite spins in opposite directions, are shown to exist in metallic
armchair nanotubes in an all-electric setup. This is a consequence of the interplay between spinorbit i...
Defect-Induced Electron Scattering in Single-Walled Carbon Nanotubes
Defect-Induced Electron Single-Walled Carbon Nanotubes

2010/11/18
We present a detailed comparison between theoretical predictions on electron scattering processes in metallic single-walled carbon nanotubes with defects and experimental data obtained by scanning tun...
High Performance In Vivo Near-IR (>1 μm) Imaging and Photothermal Cancer Therapy with Carbon Nanotubes
Vivo Near-IR (>1 μm) Imaging Photothermal Cancer Therapy

2010/11/12
Short single-walled carbon nanotubes (SWNTs) functionalized by PEGylated phospholipids are biologically non-toxic and long-circulating nanomaterials with intrinsic near infrared photoluminescence (NI...
First Principles Calculation of Field Emission from Carbon Nanotubes With Nitrogen and Boron Doping
First Principles Calculation Field Emission Carbon Nanotubes Nitrogen Boron Doping
<
2010/11/24
We investigate the eld emission properties of nitrogenated and boronated carbon nanotubes using time-dependent density functional theory, were the wave function propagation is performed using the Cra...
Exciton-Plasmon Interactions in Individual Carbon Nanotubes
Carbon nanotubes Near-field effects Excitons Plasmons
<
2010/11/18
We use the macroscopic quantum electrodynamics approach suitable for absorbing and dispersing media to study the properties and role of collective surface excitations — excitons and plasmons — in sing...

Magnetic Field Effects of Double-Walled Carbon Nanotubes
Carbon nanotubes Conductance Magnetic field
<
2010/9/25
A theoretical discussion of electronic and transport properties of a particular family of double-wall carbon nanotubes, named commensurate structures of the armchair type (n,n)@(2n,2n) is addressed. A...
Inverse Photoemission Spectroscopy of Multiwall Carbon Nanotubes
Multiwall carbon nanotubes Inverse photoemission
<
2010/9/25
Multiwall Carbon Nanotubes (MWCNTs) were synthesized by Chemical Vapor Deposition (CVD). Two different procedures were used to grow MWCNT films roughly, aligned in the direction normal to the SiO2/Si(...
High Conducting Nanowires Obtained From Uniform Titanium Covered Carbon Nanotubes
