Linear scaling density functional theory with Gaussian orbitals and periodic boundary conditions
… (PPV), and a series of carbon and boron-nitride single wall nanotubes employing basis sets of double zeta plus polarization quality, in conjunction with generalized gradient approximation and kinetic energy density dependent functionals. We also present vibrational frequencies for PPV obtained …

Nanotube reinforced thermoplastic polymer matrix composites
… conductivity, and electrical conductivity make nanotubes attractive reinforcements for polymer matrix composites. However, the structure that makes them desirable also causes highly anisotropic properties and limited reactivity with other materials. This thesis isolates these problems in two …

Design of electrode for electrochemical energy storage and conversion devices using multiwall carbon nanotubes
All-multiwall carbon nanotube (MWNT) thin films are created by layer-by-layer (LbL) assembly of surface functionalized MWNTs. Negatively and positively charged MWNTs were prepared by surface functionalization, allowing the incorporation of MWNTs into highly tunable thin films via the LbL technique. …

Strain-induced self-rolled-up semiconductor micro/nanotubes: Fabrication and characterization
Strain-induced self-rolled-up semiconductor nanotubes are a new type of building block for three-dimensional architectures. Semiconductor nanotubes (SNTs) take advantage of the lattice mismatch between different layers and are formed when the strained semiconductor layers are released from the …
