Strong room temperature visible (red-orange) photoluminescence (PL) has been observed in wet chemically etched heavily (10E19 cm-3) and lowly (10E15 cm-3) doped silicon nanowires (SiNWs). Our observations strongly suggest that visible light emission at room [...]

Due to their strong shape anisotropy, one-dimensional (1D) nanomaterials, including nanotubes, nanowires and nanofibers exhibit specific properties that are not observed in the case of their bulk or particle counterparts.1 Moreover, when such nanomaterials display [...]
Improved analytical capability for detection of organophosphate chemical agents (i.e. nerve gases) remains a high priority need in our continuing defense against future terrorist attacks. A nanopore stochastic sensing method for the rapid detection of [...]
The synthesis and characterisation of metal-organic frameworks (MOFs) based on metal centres linked by silicon-containing ligands and the investigation for their ability to take up small magnetically active molecules in order to look at the [...]
Phenolic and epoxy nanocomposites were fabricated and exposed to pulsed laser. The nanoreinforcements were alumina nanofibers (ANF) and multi-walled carbon nanotubes (MWCNT). The loading of the nanoreinforcement was kept the same for both the epoxy [...]
It has been studied by many research groups to fabricate nano-sized hole or slit array of metal film. By using various fabrication methods, such as photolithography, and nano-imprint, have been studied. However, there still remain [...]
In this communication, we report a facile solution route to synthesize single crystalline wurtzite ZnS nanowires at low temperature (170 °C) using MOCVD system. Observations on the microstructure of the as-synthesized ZnS by high-resolution electron [...]
Magnetic nanowires are of immense importance in ultrahigh density magnetic storage media, micromagnetic sensors in read heads and spintronics devices. The nanowires of binary alloys of ferromagnetic metals like Co, Ni and Fe are particularly [...]
The nanomechanical properties of Si/a-Si core-shell NWs are investigated using molecular dynamics simulations with EDIP model. Under uniaxial compressive and tensile loading, the computed Young’s modulus increases as the radius of crystalline core increases and [...]
This paper presents a 3-D Ensemble Monte Carlo ( EMC ) based simulation for 45 nm gate length MOSFET to account for the fluctuations in drain current (saturation) and threshold voltage as causes of reliability [...]
The paper reports on the investigation of using aligned carbon nanotubes (CNTs) as the pressure sensing element. Besides the unique advantages of high sensitivity, small size, low power consumption, and strong mechanical stability, the driving [...]
A new combined technology including the equal channel angular hydroextrusion (ECAH), direct hydroextrusion (HE) and drawing (D) techniques for making nanostructure wire is for the first time proposed. The main purpose of our study is [...]
This report presents a novel nanoenergetic system based on iodine oxide and aluminum thermite reaction and the study of their gas generation and thermal wave behavior during the detonation. The ignition of homogeneous mixture of [...]
The present work focused mainly to understand the influence of nanometric size on various properties of Co doped TiO2 system. several investigations were carried out. These results are original and never published earlier. For the [...]
Silicas are important supports in heterogeneous catalysis because they have very high specific surface areas, large pore volumes and offer the possibility of incorporating a variety of chemical moieties or heteroatoms within their structure or [...]
Our final goal is to make the metal nanofibers having good properties of metal and explore the mechanical properties of metalized single nanofibers. We are expecting that they would be strong like general metals. In [...]
The main motivation of this work is the absence of systematic studies of impurity doping using aqueous solution method. The synthesis of ZnO nanorods at low-cost requires facile and low-temperature approaches. Here, we report on [...]
In this study, we developed a novel assembly technique for macroscopic one-dimensional metal oxide/CNT composites. An essential feature of the technique lies in the use of non-aqueous electrolyte in place of the usual aqueous electrolyte [...]
