Journal ArticleDOI
Epitaxial Directional Growth of Indium-Doped Tin Oxide Nanowire Arrays
Pho Nguyen,Hou T. Ng,Jing Kong,Alan M. Cassell,Richard C. Quinn,Jun Li,Jie Han,Melanie McNeil,Meyya Meyyappan +8 more
TL;DR: In this paper, a single crystalline metal oxide nanowire was constructed using indium-doped tin oxide (In−SnO2) during a heteroepitaxial growth process.
Journal ArticleDOI
The Significance of Plasma Heating in Carbon Nanotube and Nanofiber Growth
Kenneth B. K. Teo,David Hash,Rodrigo G. Lacerda,Nalin L. Rupesinghe,M. S. Bell,S. H. Dalal,Deepak Bose,T. R. Govindan,Brett A. Cruden,Manishkumar Chhowalla,Gehan A. J. Amaratunga,Meyya Meyyappan,William I. Milne +12 more
TL;DR: In this article, the effect of the plasma on heating the growth substrate in plasma enhanced chemical vapor deposition (PECVD) of carbon nanotubes is characterized for the first time, and significant temperatures, as high as 700 °C, are induced from a C2H2:NH3 direct current (dc) plasma with no other heat source present.
Journal ArticleDOI
A carbon nanotube sensor array for sensitive gas discrimination using principal component analysis
TL;DR: In this article, a carbon nanotube based gas sensor array was developed for discriminating gases and vapors, which was composed of 32 sensing elements with nanomaterials, e.g. pristine single walled carbon Nanotubes (SWNTs), and SWNTs with different metal dopants and polymer coatings.
Journal ArticleDOI
Transparent Poly(methyl methacrylate)/Single-Walled Carbon Nanotube (PMMA/SWNT) Composite Films with Increased Dielectric Constants†
Lanetra M. Clayton,Arun K. Sikder,Ashok Kumar,Martin Cinke,Meyya Meyyappan,Timofey G. Gerasimov,Julie P. Harmon +6 more
TL;DR: In this paper, the dielectric constant (e') was measured via DEA and correlated to the refractive index values using the Maxwell's relationship, and the composites dissolved in methylene chloride and then cast into films exhibited enhanced transparency.
Journal ArticleDOI
Simultaneous removal of pollutants from water using nanoparticles: A shift from single pollutant control to multiple pollutant control.
TL;DR: Nanotechnology is showcased as a promising and an environmentally-friendly way to solve the limitations of current and conventional centralised water and wastewater treatment facilities but is also presented as a good substitute or supplement in areas without those facilities.
