Room temperature H 2 S gas sensor with low detection limit is necessary for practical
application. In this work, ZnFe 2 O 4 was synthesized through a simple solvothermal method …

A novel hydrogen (H 2) sensor was developed using acid-etched optical fiber coated with
zinc oxide (ZnO) nanorods. The sensing performance was done by comparing the acid …

Pd-doped α-Fe2O3 nanoparticles were synthesized by chemical coprecipitation method and
characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The …

A novel hydrogen sulfide (H 2 S) gas sensor based on multimode interference is proposed
and presented. The sensor is constructed by a 30 mm no-core fiber (NCF) and two 30 mm …

Fabrication and characterization of a surface plasmon resonance (SPR) based fiber optic
sensor for the detection of hydrogen sulphide gas have been carried out. Three kinds of …

Abstract Porous CuO/SnO 2 nanofibers were prepared by co-dissolution and
electrospinning, followed by annealing, and compounded with different amounts of carbon …

Copper oxide (CuO) nanofibres are utilised to sense the toxic and abrasive gas hydrogen
sulfide (H2S) in the ppm (parts per million) range. The detection by CuO is based on a …

Nanomaterial modified optical fiber sensor is studied for sensing H 2 S at room temperature
for very low concentrations from 1 ppm to 5 ppm. ZnO nanoparticles were embedded into …

We describe a novel fiber-optic gas sensor which hydrogen Sulfide (H2S) gas can be
detected by a silver coated fiber bragg grating (FBG). The H2S sensitive material Ag can be …

The H2S concentration in exhaled breath increases marginally with the progress of
periodontal disease, and H2S is considered to be one of the most important gases related to …
