Yotsarayuth Seekaew,Shongpun Lokavee,Ditsayut Phokharatkul,Anurat Wisitsoraat,Teerakiat Kerdcharoen,Chatchawal Wongchoosuk +5 more
TL;DR: In this article, an ink-jet printed graphene-poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite film with high uniformity over a large area is presented.
Journal ArticleDOI
Portable electronic nose based on carbon nanotube-SnO2 gas sensors and its application for detection of methanol contamination in whiskeys
TL;DR: In this paper, a portable electronic nose (E-nose) based on hybrid carbon nanotube-SnO2 gas sensors is described, which employs feature extraction techniques including integral and primary derivative, which lead to higher classification performance as compared to the classical features.
Journal ArticleDOI
Room temperature toluene gas sensor based on TiO2 nanoparticles decorated 3D graphene-carbon nanotube nanostructures
TL;DR: In this paper, the authors presented a highly sensitive room-temperature gas sensor based on 3D titanium dioxide/graphene-carbon nanotube (3D TiO2/G-CNT) fabricated by chemical vapor deposition and sparking methods.
Journal ArticleDOI
Detection and Classification of Human Body Odor Using an Electronic Nose
TL;DR: This is the first report of the application of an E-nose for armpit odor recognition and shows the capability of detecting human body odor and distinguishing the body odors from two persons in a relative manner.
Journal ArticleDOI
Multi-walled carbon nanotube-doped tungsten oxide thin films for hydrogen gas sensing.
Chatchawal Wongchoosuk,Anurat Wisitsoraat,Ditsayut Phokharatkul,Adisorn Tuantranont,Teerakiat Kerdcharoen +4 more
TL;DR: This work fabricated hydrogen gas sensors based on undoped and 1 wt% multi-walled carbon nanotube (MWCNT)-doped tungsten oxide (WO3) thin films by means of the powder mixing and E-beam evaporation technique, and is the first report on a MWCNT-doped WO3 hydrogen sensor prepared by the E- beam method.
