Optical approaches for NH 3 gas sensing are contemplated as a reliable alternative to the
conventional chemiresistive gas sensing techniques. Initially, we have briefly reviewed …

Gas pollution is a serious problem. More attention has been paid to the detection and
monitoring of toxic and harmful gases, and it is urgently needed for a sensor that could …

Gold in the form of bulk metal mostly does not react with gases or liquids at room
temperature. On the other hand, nanoparticles of gold are very reactive and useful as …

Thin‐film composite of chitosan/nickel phthalocyanine (NiPc) was electrochemically
deposited on the fingers of interdigitated gold electrodes, applying chronoamperometric …

A conductometric microsensor for measuring methanol vapor was conceived, based on
electrospun composite nanofibers of polyvinyl chloride (PVC) doped with nickel …

Monitoring of pH under extreme alkaline range is still a challenge due to the lack of accuracy
and validity. This research developed a novel pH sensor (hydrogel/BTB) based on the …

Hexanal was identified as one of the major volatile gases which are produced in degraded
dairy products and wood industries. Therefore, preliminary study on hexanal gas detection …

Efficient shielding materials are extremely important to minimize the effect of electromagnetic
interference. Currently, various composite materials are being investigated with different …

Herein, the use of multiple doping of citric acid (CA) and chitosan (CS) in polyacrylonitrile
(PAN) nanofibers over a quartz crystal microbalance is investigated as a method for …

The use of conducting polymers as sensing elements in electrochemical or chemical
sensors is a center of attraction due to their good sensitivity in changing electrical and …
