Metal oxide sensor arrays for detection of explosives at sub-parts-per million concentration levels by the differential electronic nose

Diverse Applications of Electronic-Nose Technologies in Agriculture and Forestry

“…The most common applications of electronic noses in agriculture are to monitor food quality and production processes, detect crop diseases, and identify insect infestations [1]. Some less common uses for e-nose devices include the detection of explosive gases [29], determining the niche-roles of organisms in forested agro-ecosystems [30], monitoring plant physiological processes [31,32], and identifying plants or for plant classifications via chemotaxonomy based on plant volatiles, including essential oils [30]. …”

Electronic Nose and Electronic Tongue

“…Brudzewski et al [64] designed a differential electronic nose which consists of two chemo-sensor arrays working in parallel to measure typical explosive materials including trinitrotoluene (TNT), pentaerythritolte-tranitrate (PETN), and cyclotrimethylenetrinitramine (RDX). The experimental system contains two sensor arrays instead of one.…”

Highly Sensing Properties Sensors Based on Ce-doped ZnO and SnO2 Nanoparticles to Ethanol Gas

“…The detection of different types of gases and quantification of their precisely concentration have wide applications in different fields like domestic gas alarms, medical diagnostic equipment, industrial safety, environmental pollution, military field and food industry [Papadopoulos et al (1996), Wang C et al (2009), Wetchakun et al (2011), Brudzewski et al (2012), Mielle et al (2001) and Fleming (2001)]. With numerous industries that utilize or produce ethanol, it is apparent that reliable methods are needed…”
