Robert Bogue

This paper aims to show how a range of new and emerging applications are driving technological innovations in gas sensing.

A review on recent advances of CNTs as gas sensors

Md.Masud Rana, Dauda Sh. Ibrahim, M.R. Mohd Asyraf, S. Jarin, Amanullah Tomal

This review paper aims to focus on recent advances of carbon nanotubes (CNTs) to produce gas sensors. Gas sensors are widely used for monitoring hazardous gas leakages and…

Mini pretreatment system integrated with micro pre-concentrator and micro GC column

Yanni Zhang, Jianhai Sun, Xiaofeng Zhu, Jinhua Liu, Zhanwu Ning

As the concentration of environmental samples was generally very low and existing analytical instruments had limited sensitivity, developing mini pre-treatment systems for…

Improving the sensitive property of graphene-based gas sensor by illumination and heating

Hui Li, Zhihui Gao, Weihao Lin, Wei He, Jinyan Li, Yong Yang

Graphene is a two-dimensional material. Its use has many advantages in gas sensing, but its long desorption process is problematic. The aim of this paper is to design a…

Ethylene detection using TiO2–WO3 composite sensor for fruit ripening applications

Jayaraman Kathirvelan, Rajagopalan Vijayaraghavan, Anna Thomas

The purpose of this paper was to develop a chemo-resistive sensor based on TiO₂–WO₃ composite material to detect and estimate ethylene released from the fruit ripening process to…

Simultaneous analysis of some volatile compounds in food samples by array gas sensors based on polypyrrole nano-composites

Sajad Pirsa, Fardin Mohammad Nejad

The purpose of this paper is to construct an array of sensors using polypyrrole–zinc oxide (PPy–ZnO) and PPy–vanadium (V; chemical formula: V₂O₅) fibers. To test responses of…

Towards bionic noses

Krishna Chandra Persaud

The purpose of this paper is to review recent progress in electronic nose technologies, focusing on hybrid systems combining biological elements with physical transducers.

Water vapor concentration measurements using TDALS with wavelength modulation spectroscopy at varying pressures

Wei Wei, Jun Chang, Qingjie Huang, Qiang Wang, Yuanyuan Liu, Zengguang Qin

As measurement results of optical gas sensors are constantly affected by the pressure of a target gas, approaches must be taken to modify the results. The purpose of this paper is…

Experimental research on a reflective optical fiber bundle hydrogen gas sensor

Lujun Cui, Huichao Shang, Yan-long Cao, Gao-feng Zhou

Long life and high hydrogen sensitivity are the crucial performance parameters for an optical fiber hydrogen sensing membrane, and these are the fundamental areas of study for an…

Gas concentration detection via multi-channeled air sampling method

Longfei Hou, Dan Wang, Bingxuan Du, Xinmin Qian, Mengqi Yuan

The purpose of this paper is to present a new technique for monitoring gas leakage in underground pipelines to prevent dangerous explosions.

Design and implementation of atmospheric multi-parameter sensor for UAV-based aerosol distribution detection

Fangjie Yu, Yunfei Liu, Longqing Fan, Linhua Li, Yong Han, Ge Chen

In this paper, a light-weight, low-power atmospheric multi-parameter sensor (AMPS), which could be mounted on small flying platforms such as a tethered balloon, a quad-rotor…
