Solvent-Resistant Polymeric Sensors for Adulteration Detection in Liquid Fuels
(AMER SCIENTIFIC PUBLISHERSVALENCIA, 2012)
Polymeric sensors with improved resistance to organic solvents were produced via the layer-by-layer thin film deposition followed by chemical cross-linking. According to UV-vis spectroscopy, the mass loss of polyaniline/poly(vinyl ...
A sensor array based on mass and capacitance transducers for the detection of adulterated gasolines
(ELSEVIER SCIENCE SA, 2009)
The simultaneous use of different sensors technologies is an efficient method to increase the performance of chemical sensors systems. Among the available technologies, mass and capacitance transducers are particularly ...
Optical chemical sensors using polythiophene derivatives as active layer for detection of volatile organic compounds
(Elsevier B.V. Sa, 2012-02-20)
Several studies on polythiophene gas sensors, based mainly on electrochemical and gravimetric principles can be found in the literature. However, other principles of gas detection, such as optical and thermal, are still ...
Design of a wireless sensor network for greenhouses temperature analysisProjeto de uma rede de sensores sem fio para análise da temperatura em casas de vegetação
(2018-10-01)
This work presents a wireless sensor network designed with fifteen temperature sensors to monitor this parameter variation inside a greenhouse, where all temperature values were transmitted by radio to a distant computer ...
Development of biomimetic sensor for fast and sensitive detection of Norfloxacin
(2010)
A biomimetic sensor is proposed as a promising new analytical method for determination of norfloxacin (NF) in pharmaceuticals. The sensor was prepared by modifying a glassy carbon electrode surface with a Nafion® membrane ...
Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
