Study of frequency dependent electrical properties of ZnO nanorods
(Emerald Group Publishing Limited, 2013)
Purpose - The purpose of the current research is to use impedance spectroscopy to study the AC parameters that varied with frequency such as impedance, dielectric constant and conductivity of ZnO nanorods MSM structure in ...
Selection of optimal parameters in fabrication of poly (dimethylsiloxane) microfluidics using taguchi method
(American Scientific Publishers, 2013-01)
The excellent performance and achievements by the microfluidics systems at fluid flow manipulation in the recent years have ignited the passion and interest of many researchers around the world, Since a microfluidic is ...
The electroosmosis mechanism for fluid delivery in PDMS multi-layer microchannel
(American Scientific Publishers All rights reserved., 2013-01)
Here we reported on fabrication of multi-layer microstructures that takes the advantage of electroosmosis to mix fluids. Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. ...
Alternative-current electrochemical etching of uniform porous silicon for photodetector applications
(Electrochemical Science Group, 2013)
The twining of alternative-current (AC) with electrochemical etching (ECE) to fabricate porous silicon (PS) is studied. The porosity percentage is obtained by gravimetric analysis. The effect of different current densities; ...
Structural and morphological studies of cadmium sulfide nanostructures
(Trans Tech Publications, 2013)
Cadmium sulfide (CdS) nanostructures were prepared with different spin coating speed 1000 and 3000 rpm and molarities of Cd:S to be 1.2 to 0.01 mol/L using sol-gel spin coating technique. It is found that the average grain ...
Impact of hydrogen concentrations on the impedance spectroscopic behavior of Pd-sensitized ZnO nanorods
(Licensee Springer, 2013)
ZnO nanorods were synthesized using a low-cost sol-gel spin coating technique. The synthesized nanorods were consisted of hexagonal phase having c-axis orientation. SEM images reflected perpendicular ZnO nanorods forming ...
Synthesis of single-walled carbon nanotubes: Effects of active metals, catalyst supports, and metal loading percentage
(Hindawi Publishing Corporation, 2013)
The effects of active metals, catalyst supports, and metal loading percentage on the formation of single-walled carbon nanotubes (SWNTs) were studied. In particular, iron, cobalt, and nickel were investigated for SWNTs ...
Design and fabrication of PDMS microchamber for fast reaction assays in biosensing application.
(Trans Tech Publications, 2013)
A simple design of a microchamber for use in reacting assays with limited sample availability has been proposed, analyzed using COMSOL 3.5 Multiphysics simulation and fabricated using soft-lithography technique. The design ...
Morphological, structural, and electrical characterization of sol-gel-synthesized ZnO nanorods
(Hindawi Publishing Corporation, 2013)
ZnO nanorods were grown on thermally oxidized p-type silicon substrate using sol-gel method. The SEM image revealed high-density, well-aligned, and perpendicular ZnO nanorods on the oxidized silicon substrate. The XRD ...
Optoelectronic properties of GaAs and AlAs under temperature effect
(Elsevier GmbH, 2013-08)
An application study of optoelectronic properties as a function of the temperature for GaAs and AlAs according to our model has been presented using empirical pseudopotential method (EPM). The structural phase transition ...
