Synthesis of High-Quality Vertically Aligned Carbon Nanotubes on Bulk Copper Substrate for Thermal Management
(Georgia Institute of Technology, 2010-05)
Vertically aligned carbon nanotubes (VACNTs) grown on bulk copper substrate are of great importance for real-life commercial applications of carbon nanotubes (CNTs) as thermal interface materials in microelectronic packaging. ...
Gel spun polyacrylonitrile based carbon fibers containing lignin and carbon nanotubes
(Georgia Institute of Technology, 2017-01-13)
Forestry bioproduct lignin has been long proposed as an ideal material for carbon fiber precursor due to its abundance, renewability, high carbon yield and cost-effectiveness as the biorefinery by-product. However, little ...
Collective oscillations in a single-wall carbon nanotube excited by fast electrons
(Georgia Institute of Technology, 2001-08-31)
Electron energy loss spectroscopy is a well adapted tool for the investigation of the valence excitations of individual nanometer-size particles. The interpretation of the loss spectra of such small particles, however, ...
Conductance quantization in multiwalled carbon nanotubes
(Georgia Institute of Technology, 1999)
We present results of carbon nanotube conductance measurements. The experiments were performed
using an scanning probe microscope (SPM) system where a carbon nanotube fiber is connected
to the SPM tip and then lowered ...
Carbon Nanotubes: Chemical Vapor Deposition Synthesis and Application in Electrochemical Double Layer Supercapacitors
(Georgia Institute of Technology, 2005-03-08)
Carbon nanotubes (CNTs) have become a popular area of materials science research due to their outstanding material properties coupled with their small size. CNTs are expected to be included in a wide variety of applications ...
Valence excitations in individual single-wall carbon nanotubes
(Georgia Institute of Technology, 2002-04-22)
We report on measurements of the plasmon losses of individual single-wall carbon nanotubes by electron energy-loss spectroscopy in a high-resolution transmission electron microscope. The experimental data are compared to ...
In situ imaging of field emission from individual carbon nanotubes and their structural damage
(Georgia Institute of Technology, 2002-02-04)
Field emission of individual carbon nanotubes was observed by in situ
transmission electron microscopy. A fluctuation in emission current was due to a
variation in distance between the nanotube tip and the counter ...
Effect of poly(methyl methacrylate) wrapping on the structure and properties of CNT films, and polymer/CNT films and fibers
(Georgia Institute of Technology, 2017-02-24)
Carbon nanotubes (CNTs) exhibit high electrical and thermal conductivity and good mechanical properties, making them suitable fillers for composites. Their effectiveness as a filler is affected by their state of aggregation. ...
Comparison of Short and Long Multi Wall Carbon Nanotube and Polymethyl Methacrylate Composites
(Georgia Institute of Technology, 2015-04)
Polymers are extremely dynamic and widely used materials, with the ability to create new and exciting structures. One such example is the capability for the amorphous polymer to form a segregated, organized network when ...
Gel spun PAN and PAN/CNT based carbon fibers: From viscoelastic solution to elastic fiber
(Georgia Institute of Technology, 2015-04-06)
This study focuses on the processing, structure, and properties of gel spun polyacrylonitrile (PAN) and polyacrylonitrile/carbon nanotube (PAN/CNT) carbon fibers. Gel spun PAN based carbon fibers are manufactured beginning ...
