Nanotechnology has advanced at a rapid growth over recent years. Based on carbon
nanomaterials (CNMs), surface plasmon resonance (SPR) sensors have been developed …

The selective catalytic oxidation of NH3 (NH3-SCO) into N2 and H2O is an efficient
technology for NH3 abatement in diesel vehicles. However, the catalysts dedicated to NH3 …

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 …

Due to their high sensitivity and selectivity, low cost, and good compatibility for sensor array
integration, colorimetric gas sensors are widely used in hazardous gas detection, food …

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 …

A sensing enhancement sensor based on hybrid film fiber has been proposed to detect
ammonia. The hybrid film coated on the MMF-SMF-MMF (Multimode Fiber–Single-mode …
