“…B. Renganathan, co-author of the previous paper, has published multiple articles regarding gas sensors following a similar procedure and using different materials. In particular, ammonia gas sensors have been studied using a setup similar to the one represented in Figure 3 using nanocrystalline ZnO [ 62 ], nanocrystalline CeO 2 [ 63 ], nanoparticles of V 2 O 5 and nanoparticles of WO 3 [ 64 ], nanocrystalline SnO 2 and SnO 2 film [ 65 ], nanocrystalline TiO 2 [ 20 ], Zn 3 (VO 4 ) 2 nanopowder [ 66 ], nanocrystalline Sm 2 O 3 [ 67 ] and single and multi-walled carbon nanotubes [ 68 , 69 ] fabricated by dip coating techniques [ 70 ]. Table 1 summarizes the described ammonia sensors and their most relevant parameters.…”

Pollution in cities induces harmful effects on human health, which continuously increases the global demand of gas sensors for air quality control and monitoring. In the same manner, the industrial sector requests new gas sensors for their productive processes. Moreover, the association between exhaled gases and a wide range of diseases or health conditions opens the door for new diagnostic applications. The large number of applications for gas sensors has permitted the development of multiple sensing technologies. Among them, optical fiber gas sensors enable their utilization in remote locations, confined spaces or hostile environments as well as corrosive or explosive atmospheres. Particularly, Lossy Mode Resonance (LMR)-based optical fiber sensors employ the traditional metal oxides used for gas sensing purposes for the generation of the resonances. Some research has been conducted on the development of LMR-based optical fiber gas sensors; however, they have not been fully exploited yet and offer optimal possibilities for improvement. This review gives the reader a complete overview of the works focused on the utilization of LMR-based optical fiber sensors for gas sensing applications, summarizing the materials used for the development of these sensors as well as the fabrication procedures and the performance of these devices.

“…These sensing materials may be used as dyes (99), crystals (100) or as a thin film placed on the prisms (101) or fiber optics. Fiber optic gas sensors are usually based on the fiber from which clad is removed, and core modified with sensing membranes, such as zinc vanadate (102) or Ho-doped bismuth oxide (103) for ammonia, ethanol, methanol and acetone gases detection, Nile red with polyvinylpyrrolidone for VOCs (104) and nano-crystalline zinc oxide for acetone, isopropyl alcohol and benzene gases detection (105).…”

A vast majority of people today spend more time indoors than outdoors. However, the air quality indoors may be as bad as or even worse than the air quality outside. This is due to the continuous circulation of the same air without proper ventilation and filtration systems, causing a buildup of pollutants. As such, indoor air quality monitoring should be considered more seriously. Indoor air quality (IAQ) is a measure of the air quality within and around buildings and relates to the health and comfort of building occupants. To determine the IAQ, computer modeling is done to simulate the air flow and human exposure to the pollutant. Currently, very few instruments are available to measure the indoor air pollution index. In this paper, we will review the list of techniques available for measuring IAQ, but our emphasis will be on indoor air toxicity monitoring.

“…With the rapid growth of industrialization progress, energy crisis and environmental problems have become extremely serious, which is stimulating the development of advanced materials. In recent years, vanadates have attracted lots of attention due to their unusual electrochemical, redox properties, and potential applications as sodium‐ion batteries, photoanodes, supercapacitors, gas sensors, and so on . Especially, iron vanadates FeVO 4 , Fe 2 V 4 O 13 , FeV 2 O 4 , and FeV 3 O 8 semiconductors exhibit narrow bandgap, high chemical stability, eco‐friendly, and low‐cost, which make them become promising photoelectrode materials for solar photoelectrochemical water splitting, lithium‐ion batteries, and Fenton‐like catalysts for degradation of organic pollutant .…”

The thermodynamic, lattice dynamical, and elastic properties of iron‐vanadium oxides are studied from experiments and first‐principles calculations. The high‐temperature heat capacities of FeVO4, Fe2V4O13, FeV2O4, and FeV3O8 are accurately measured using a three‐dimensional (3D) sensor. The phase diagram of Fe‐V‐O system at 873 K is reasonably predicted combining the calculated enthalpy of formation and entropy. The phonon dispersions of FeVO4 and Fe2V4O13 indicate that they are dynamically stable. The high‐frequency vibrations are dominated only by V and O atoms mainly due to the stronger V‐O bonding. All Raman and infrared (IR) frequencies at zone‐center are assigned unambiguously and different types of vibration are established. The physical properties such as elastic constant, bulk modulus, shear modulus, Young's modulus, Poisson's ratio, Debye temperature, elastic wave velocity, and minimum thermal conductivity of FeVO4 and Fe2V4O13 are calculated.
