1. Patterned Nanocomposite of Carbon Nanotube/Polymer
University essay from Umeå universitet/Institutionen för fysikAbstract : Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix. READ MORE

2. Investigation of catalyst composition for cobalt and iron catalyst on the chirality of grown single walled carbon nanotubes
University essay from Umeå universitet/Institutionen för fysikAbstract : The synthesis of type-enriched semiconducting or metallic single-walled carbon nanotubes (sc/m-SWCNTs) with high quality by means of catalytic chemical vapor deposition (CCVD) are essential prerequisites for implementing of SWCNTs into nanodevices. In particular, the Fe−Co bimetallic catalysts system is promising due to its ability to grow SWCNTs by CCVD. READ MORE

3. Carbon Nanotube Raman Spectra Calculations using Density Functional Theory
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Utilizing density functional theory (DFT) the Vienna Ab initio Simulation Package (VASP) was used to calculate the Raman spectra for five single-walled carbon nanotubes (SWCNTs) with chiralities (4,4), (6,6), (8,0), (12,0) and (7,1). The radial breathing mode (RBM), when compared with experimental frequencies, shows good correlation. READ MORE

4. Thermal Stability of Carbon Nanotubes and Role of Intercalation
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Research in carbon nanotubes (CNTs) has become a very active field in the past decades, with much interest in their electronic and mechanical properties. However, the thermal properties of CNTs are still not well understood, in particular the process of annealing; i.e. purification of samples by desorption of internal and external impurities.

5. Atomic Force and Scanning Tunneling Microscopy Studies of Single Walled Carbon Nanotubes
University essay from Institutionen för ingenjörsvetenskap, fysik och matematikAbstract : In this diploma work I present the first experimental investigations of carbon nanotubes at Karlstads University. Raw nanotube powder of single walled carbon nanotubes have been dispersed primarily in 1,2-dichloroethane. The solutions have been spincoated on Au(111) substrates. READ MORE
