Fabrication of silicon nitride ion sensitive field-effect transistor for pH measurement and DNA immobilization/hybridization
Uda, Hashim, Prof. Dr.; Soon, Weng Chong; Liu, Wei Wen, Dr. (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 ... -
Precise alignment of individual single-walled carbon nanotube using dielectrophoresis method for development and fabrication of pH sensor
Uda, Hashim, Prof. Dr.; Foo, Wah Low; Liu, Wei Wen, Dr. (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, ... -
A study on the effect of calcination temperature on the graphitization of carbon nanotubes synthesized by the decomposition of methane
Liu, Wei Wen, Dr.; Tijjani Adam, Shuwa; Azizan, Aziz, Assoc. Prof. Dr.; Chai, Siang Piao; Abdul Rahman, Mohamed, Prof. Dr.; Uda, Hashim, Prof. Dr. (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 ... -
Synthesis of single-walled carbon nanotubes: Effects of active metals, catalyst supports, and metal loading percentage
Liu, Wei Wen, Dr.; Azizan, Aziz, Assoc. Prof. Dr.; Chai, Siang Piao, Dr.; Abdul Rahman, Mohamed, Prof. Dr.; Uda, Hashim, Prof. Dr. (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 ...
