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 ...
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 ...
Novel in-house fabrication of nano lab-on-chip devices
(Bentham Science Publishers, 2013)
20nm SiNWs transducers have been fabricated by means of simple in-house fabrication method. A low cost, simple top-down approach has been successfully used for the fabrication of very sensitive SiNWs. The fabrication was ...
Sol-gel synthesis of Pd doped ZnO nanorods for room temperature hydrogen sensing applications
(Elsevier Ltd and Techna Group S.r.l., 2013-08)
A sol-gel spin coating technique was described for the synthesis of Pd doped ZnO nanorods for hydrogen sensing applications. The nanorods were hexagonal in shape, 50-100 nm in diameter and uniform in distribution. They ...
