Fiber-optic sensors have developed rapidly because of their excellent sensing
performances and abilities to detect in remote and harsh environments. However, on some …

High-quality optical fibers can be produced now at a low cost and large quantity, and this
has further promoted the development of fiber-optic (chemical) sensors. After over 30 years …

Most volatile organic compounds (VOCs) are toxic, carcinogenic, and mutagenic, and can
have serious effects on human health and the ecological environment. Therefore, the …

Titanium dioxide (TiO2) has been extensively investigated in interdisciplinary research (such
as catalysis, energy, environment, health, etc.) owing to its attractive physico-chemical …

Exposure to volatile organic compounds (VOCs) can exert serious impacts on human health.
The detection and identification of VOCs are, therefore, important both in outdoor and indoor …

In the work, a cholesteric liquid crystal film coated side polished fiber (CLCFC-SPF) is
demonstrated to sense the volatile organic compound (VOC) gas. In the CLCFC-SPF, the …

The fabrication of low-temperature metal oxide-based sensors with highly sensitive to
carcinogenic organic-amines remains challenging. Herein, a biomorphic CuO-5 material …

In this paper, we propose an innovative, simple and inexpensive gas sensor based on the
variation in the magnetic properties of nanoparticles due to their interaction with gases. To …

Fiber-optic sensors based on porous silica films, and operating in reflectance mode are very
suitable for detecting volatile organic compounds (VOCs) because they combine the …

Because of the explosion in the building industry as well as the growing need to improve
aesthetic durability and lower environmental pollution worldwide, eco-friendly photocatalytic …
