Metrological Investigation of the (6,5) Carbon Nanotube Absorption Cross Section
Laura Oudjedi, A. Nicholas G. Parra-Vasquez, Antoine Godin +2
Using single-nanotube absorption microscopy, we measured the absorption cross section of (6,5) carbon nanotubes at their second-order optical transition. We obtained a value of 3.2…
Nanoscale Thermotropic Phase Transitions Enhance Photothermal Microscopy Signals
A. Nicholas G. Parra-Vasquez, Laura Oudjedi, Laurent Cognet +1
The photothermal heterodyne imaging technique enabled studies of individual weakly absorbing nano-objects in various environments. It uses a photo-induced change in the refractive…
Modeling the phase behavior of polydisperse rigid rods with attractive interactions, with applications to SWNTs in super acids
Micah J. Green, A. Nicholas G. Parra-Vasquez, Natnael Behabtu +1
The phase behavior of rodlike molecules with polydisperse length and solvent-mediated attraction and repulsion is described by an extension of the Onsager theory for rigid rods. A…
Alignment Dynamics of Single-Walled Carbon Nanotubes in Pulsed Ultrahigh Magnetic Fields
J. Shaver, A. N. G. Parra-Vasquez, S. Hansel +6
We have measured the dynamic alignment properties of single-walled carbon nanotube (SWNT) suspensions in pulsed high magnetic fields through linear dichroism spectroscopy. Millisec…
