In this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. In order that studies on different types of nanotubes be comparable, the chiral vectors of C and Si-C nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...

In this work we reported the carbon dioxide adsorption (CO2) in six different nanostructures in order to investigate the capturing capacity of the materials at nanoscale. Here we have considered the three different nanotubes including zinc oxide nanotube (ZnONT), silicon carbide nanotube (SiCNT) and single walled carbon nanotube (SWCNT). Three different chiralities such as zigzag (9,0), armchai...

Title of dissertation: ELECTRON TRANSPORT SIMULATIONS AND BAND STRUCTURE CALCULATIONS OF NEW MATERIALS FOR ELECTRONICS: SILICON CARBIDE AND CARBON NANOTUBES. Gary Pennington, Doctor of Philosophy, 2003 Dissertation directed by: Professor Neil Goldsman Department of Electrical Engineering Silicon carbide (SiC) and carbon nanotubes (CNTs) are two materials which have promising potential in electr...

Silicon carbide is one of the most promising materials for power electronic devices capable of operating at extreme conditions. The widespread application of silicon carbide power devices is however limited by the presence of structural defects in silicon carbide epilayers. Our experiment demonstrates that optical second harmonic generation imaging represents a viable solution for characterizin...

The inferred crystallographic class of circumstellar silicon carbide based on astronomical infrared spectra is controversial. We have directly determined the polytype distribution of circumstellar SiC from transmission electron microscopy of presolar silicon carbide from the Murchison carbonaceous meteorite. Only two polytypes (of a possible several hundred) were observed: cubic 3C and hexagona...

The discoveries of superconductivity in heavily boron-doped diamond, silicon and silicon carbide renewed the interest in the ground states of charge-carrier doped wide-gap semiconductors. Recently, aluminium doping in silicon carbide successfully yielded a metallic phase from which at high aluminium concentrations superconductivity emerges. Here, we present a specific-heat study on superconduct...

Separation of cyanide, as a model contaminant, from aqueous solution was investigated using molecular dynamics simulations. In this research, cyanide separation was investigated using armchair silicon carbide (SiC) nanotubes of four different diameters at different applied pressures. The systems included (5,5), (6,6), (7,7) and (8,8) SiC nanotubes placed between two graphene sheets, and an exte...
