Design development of acoustic waves based sensitive sensors for Escherichia coli O157:H7 detection
(Trans Tech Publications Inc., 2014-04)Food contamination has become critical issue and is being worse due to the insensitive detection devices. One of the dangerous food contaminations is by Escherichia coli (E.coli) O157:H7, one of the harmful bacterial ... -
Modeling development of a high-sensitivity escherichia coli O157:H7 detection based on SH SAW sensor
(Trans Tech Publications, 2014-04)Surface acoustic waves based devices were initially developed for the telecommunication purpose such as signal filters and resonators. The acoustic energy is strongly confined on the surface of the surface acoustic waves ... -
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 ... -
Experimental determination of the performance of rice husk-carbon nanotube composites for absorbing microwave signals in the frequency range of 12.4-18 GHz
(EMW Publishing, 2013)Composites of rice husks and carbon nanotubes (RHC-NTs) are an innovation in improving the absorption of microwave signals. Rice husks, which are an agricultural waste material, have been found to possess a significant ... -
A study on the effect of calcination temperature on the graphitization of carbon nanotubes synthesized by the decomposition of methane
(Trans Tech Publications, 2014)The effect of calcination temperature for Fe2O3/MgO catalysts on the formation of carbon nanotubes (CNTs) was examined. CNTs were synthesized over Fe2O3/MgO catalysts calcined at different temperatures by catalytic ... -
Formation of carbon nanotubes from methane decomposition: Effect of concentration of Fe₃O₄ on the diameters distributions
(Trans Tech Publications, 2014)Fe₃O₄ was used to synthesize narrow diameter of carbon nanotubes (CNTs). The effect of concentration of Fe₃O₄ on the diameters of carbon nanotubes (CNTs) synthesized by methane decomposition at 1000°C was investigated. We ... -
Precise alignment of individual single-walled carbon nanotube using dielectrophoresis method for development and fabrication of pH sensor
(Hindawi Publishing Corporation, 2013)Development and fabrication of single-walled carbon nanotube (SWNT) based pH sensor were reported. The precise alignment of individual SWNT using dielectrophoresis method between the two microgap electrodes was conducted, ... -
Fabrication of silicon nitride ion sensitive field-effect transistor for pH measurement and DNA immobilization/hybridization
(Hindawi Publishing Corporation, 2013)The fabrication of ion sensitive field-effect transistor (ISFET) using silicon nitride (Si3N4) as the sensing membrane for pH measurement and DNA is reported. For the pH measurement, the Ag/AgCl electrode was used as the ...
