Gas monitoring in mines and tunnels is the key to ensuring safe production. Nowadays,
optical fiber gas sensors depend on the advantages of nonelectrical signal transmission …

For applications involving water cleanup, metal oxide nanoparticles are exceptionally
successful. They are useful for the adsorption and photocatalytic destruction of organic …

In this paper, polyoxometalates (POMs) electron acceptors were introduced into a classical p-
type gas sensitive ceramic-copper oxide (CuO). Then, we investigated the effect of …

Copper ion is closely associated with the ecosystem and human health, and even a little
excessive dose in drinking water may result in a range of health problems. However, it …

The Pt-loaded WO 3 materials have been synthesized via simple hydrothermal and
chemical reduction methods. The microstructure of prepared Pt-WO 3 exhibits as nanorods …

In this work, we present a comparative study on the influence of the geometric shape of
plastic optical fiber (POF) sensors in their response to refractive index (RI) of external media …

As a typical p-type semiconductor gas-sensing material, LaFeO3 has good response
stability to H2S, but its responsiveness is low, and the detection limit is not low enough for …

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 …

Among the many fluoropolymers, polyvinylidiene fluoride (PVDF) has been well-known
since 1960s and is preferred for various electronic applications owing to its lower cost …

Dysregulated production of hydrogen sulphide in the human body has been associated with
various diseases including cancer, underlining the importance of accurate detection of this …
