Authors may submit manuscripts and track their progress through the system, hopefully to publication. Reviewers can download manuscripts and submit their opinions to the editor. Editors can manage the whole submission/review/revise/publish process.
Journal of Nanomaterials & Molecular Nanotechnology is organizing & supporting 4th International Conference on Nanotek & Expo during December 01-03, 2014 in San Francisco, USA with the theme of Challenging Aspects and Frontiers in Nanoscience & Nanotechnology.
Synthesis and Characterization of Titania Nanotubes on Titanium alloy IMI 834 by Electrochemical Anodization Process
Electrochemical anodization offers large surface area architecture with precisely controllable nanoscale features in the fabrication of highly ordered vertically oriented TiO2 nanotube arrays. Abundant research work has been accomplished on pure titanium and their alloys like Ti 64, TiNb, TiAl etc. Yet, no work has been proclaimed on Titanium alloy IMI 834. In the present investigation, the synthesis of highly ordered Titania nanotubes by electrochemical anodization of the alloy IMI 834 in different electrolytes was carried out. The synthesized nanotubes were characterized by Scanning Electron Microscope (SEM), Field Emission Scanning Electron Microscope (FESEM), Electron Dispersive Spectroscopy (EDS) and X-ray diffraction (XRD) techniques. The results spectacles that the size and morphology rely on the electrolyte composition. Among the electrolytes, the combination of 0.5wt% HF and 1M phosphoric acid is more suitable in producing ordered Titania nanotubes on titanium alloy IMI 834.
Rapid Induced Aggregation of Gold Nanoparticles by Diolefinic Dyes
Aggregation kinetics of gold nanoparticles (Au NPs) interaction in the presence of some diolefinic dyes, namely 1,4-bis (β-pyridyl-2-vinyl) benzene (P2VB), 1,4 bis(2-methylstyryl) benzene (MSB) and 2,5 distyrylpyrazine (DSP), were studied in methanol using steady state UV-Vis spectrophotometry and stopped-flow spectrophotometry. All three dyes induced the aggregation of Au NPs, but with different rates. The rate of interaction of P2VB and MSB with Au NPs were in time-scale of milliseconds, 6 ms-1 and 3.25 ms-1, respectively, while the interaction between DSP and Au NPs occurred in time-scale of minutes. The rates of interaction between Au NPs and these dyes go in the order of P2VB > MSB » DSP. The density functional theory (CAM-B3LYP) predicted that the dye with higher group charge on the terminal moieties possess higher affinity toward the aggregation as it strengthen its electrostatic interactions with the citrate-capped Au NPs.
Self-Assembling 1,4,5,8-Naphthalentetracarboxylic Diimide- Microwires for Optoelectronic Devices
The widespread use of organic electronic devices requires simple yet effective synthesis techniques to create materials with low-cost and high performance. We report the solution phase crystallization of 1,4,5,8-naphthalenetetracarboxylic diimide (NDI) microwires from dimethylsulfoxide. These microwires were characterized by means of scanning electron microscopy, thermal analysis, and infrared and fluorescence spectroscopies. The microwires were also characterized for their electrical properties and were shown to exhibit an n-type semi-conductive property as well as photoresponsive changes in conductivity. The electron mobility within the NDI microwires was determined to be lower than previous literature reports, yet the combination of photo-responsive changes in electrical conductivity may hold promise of photo-sensors, organic light-emitting diodes, and other optoelectronic devices.
Characteristics of Dielectric Dispersion in Epoxy/Polyhedral Oligomeric Silsequioxane Nanocomposites
Multiple-arc analysis is used in conjunction with a generalized relaxation time distribution (GRTD) to derive dielectric constant, dielectric loss and a.c conductivity relations as function of frequency for epoxy/ polyhedral oligomericsilsequioxane (POSS) nanocomposites. The validity of this methodology is examined by comparing reported measurements with those calculated from relations obtained. The values are shown to agree satisfactorily over the frequency range 100kHz to 1000kHz.
Influences of Dopant Concentration on Crystallography, Optical and Electrical Properties of Cadmium Oxide Nanoparticles
Cadmium oxide (CdO) nanoparticles doped with different amount of rare earth metal Neodymium (Nd) ions have been prepared by Chemical co precipitation method. The doping level was varied from [Nd/Cd] = 0.1 to 10 wt%. Crystallography analysis of these materials is carried out by X- ray diffraction (XRD) which reveals that average crystalline size is in nano region i.e. 30-30.8 nm. The synthesized nanomaterial was characterized by means of X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier transformation infrared spectroscopy (FTIR), UV-Visible Spectroscopy (UV-Vis). Electrical properties were also studied as a function of dopant concentration. Present studies also investigate the effect of varying dopant concentration on morphology and topography of as prepared nanomaterial.
