Effect of single wall carbon nanotube networks on gas sensor response and detection limit
Deepak Kumar,Deepak Kumar,Poornendu Chaturvedi,Praveen Saho,Pika Jha,Abhilasha Chouksey,Mohan Lal,J. S. Rawat,R. P. Tandon,P.K. Chaudhury +9 more
TL;DR: In this article, a single wall carbon nanotube (SWNT) based gas sensor is fabricated with mainly two type of surface-networks, (i) SWNT random network (CNT-TFR) and (ii) CNT-μR).
Journal ArticleDOI
4-(Hexafluoro-2-hydroxy isopropyl)aniline functionalized highly sensitive flexible SWCNT sensor for detection of nerve agent simulant dimethyl methylphosphonate
Deepak Kumar,Deepak Kumar,Pika Jha,Abhilasha Chouksey,J. S. Rawat,R. P. Tandon,P.K. Chaudhury +6 more
TL;DR: In this paper, flexible single walled carbon nanotube (SWCNT) resistive sensor is functionalized with 4-(Hexafluoro-2-hydroxy isopropyl)aniline (HFiP-1) to enhance the response of the sensor towards DMMP vapors.
Journal ArticleDOI
Titanium buffer layer for improved field emission of CNT based cold cathode
S. Srividya,Seema Gautam,Pika Jha,Prashant Kumar,A. Kumar,U. S. Ojha,J. S. Rawat,Surendra Pal,P.K. Chaudhary,Harsh,Ravindra Kumar Sinha +10 more
TL;DR: In this article, a buffer layer of titanium (Ti) is deposited prior to the catalyst deposition and the growth was carried out using chemical vapor deposition (CVD) technique and a significant increase in emission current density was achieved by the use of titanium buffer layer due to much less dense growth of CNTs of smaller diameter.
Journal ArticleDOI
Functionalization Of Carbon Nanotubes With Metal Phthalocyanine For SELECTIVE Gas Sensing Application
Pika Jha,Mohini Sharma,Abhilasha Chouksey,Poornendu Chaturvedi,Deepak Kumar,Garima Upadhyaya,J. S. Rawat,P.K. Chaudhury +7 more
TL;DR: In this article, a composite of hydroxylated single-walled carbon nanotubes and copper phthalocyanine (CuPc) was obtained for detection of NOx.
Journal ArticleDOI
Study of the effect of orbital on interaction behaviour of SWCNT- metal phthalocyanines composites with ammonia gas
TL;DR: In this article, the effect of central metal atom on interaction behavior of a composite constituted of two materials, Single walled carbon nanotubes (SWCNT) and metal phthalocyanines (MPcs) with ammonia gas was analyzed.
