ZnO has unique properties such as wide-bandgap (3.37eV) and large exciton binding energy (60meV) at room temperature. These properties made ZnO a promising material for short wavelength photonic devices for examples, light emitting diode (LED) [...]
Metallic nanowires have attracted much attention due to their unique mechanical, magnetic, optical and electronic properties, and their function as well-defined building blocks for nanodevices.1-3 Tungsten (W), in particular, is of great interest, being promising [...]
Recently we showed large scale fabrication of field-effect transistors from horizontal ZnO nanowires (NWs) on a-plane sapphire. We are interested in understanding the factors that induce the unique growth direction of horizontal ZnO NWs and [...]
We present the room temperature detection of 100 ppm carbon monoxide using metal ( Pd and Au) decorated Zinc Oxide (ZnO) nanowires. Zin oxide nanowires were grown via Vapor Liquid Solid method whreas the palladium [...]
Low-cost, nonpoisonous and highly sensitive and selective sensors are needed for detection of various gases in the environment. ZnO tetrapod have potential application as chemical sensors. Our current experiments have shown that ZnO tetrapod sensor [...]
ABSTRACT A CMOS scaling is approaching the limit imposed by gate oxide tunneling. Double gate MOSFET (DGMOSFET) with undoped body has become very attractive for scaling CMOS devices down to nanometer size. Device simulation predict [...]
The integration of printable transistors is an issue of recent work. Different proposals base on ZnO nanoparticle inks, which have to undergo a post-deposition annealing in order to improve the film quality and burn away [...]
With a view to understand not only the nanosize dependent properties of microstructure and electronic properties, but also to study the correlations between the surface effects associated with the magnetic nano-particles, especially the changes in [...]

Anodized titanium oxide containing highly ordered, vertically oriented TiO2 nanotube arrays is a nanomaterial architecture that shows promise for diverse applications. In this paper, an anodization synthesis using HF-free aqueous solutions is described. The anodized [...]
Recently, silicon nanotubes (SiNTs) have attracted considerable attention. However, it has been challenging to grow SiNTs without any template. Another challenge is to engineer the shape of SiNTs, which to date has been limited mostly [...]

Transition metal doped titania has been revealed as a promising diluted magnetic semiconductor. We report the synthesis of TiO2:Fe and of mixed Ti and Fe oxides by pulsed laser deposition. The obtained layers were analyzed [...]
A synthetic approach for the fabrications of Janus and Saturn colloids was demonstrated by the sequential embedment and surface modification of silica colloids. Electrospinning of poly(methyl methacrylate) (PMMA) and poly(4-vinyl pyridine) (P4VP) blends produced polymer [...]
The objective of this study is to elaborate the use of nano filters for controlling the pollution of the industries coming out of the chimneys. The nano filters allow small gaseous molecules to pass trough [...]
Metalized and monodisperse polymer particles with diameter ranging from 0.5 to 30 µm are increasingly used in developing new electrical packaging technology, such as Anisotropic Conductive Adhesives (ACA) in Flat Panel Displays (FPDs). In these [...]
