Forest fire spread out in an area having combustible material in the summer season with high temperature. It burns the area and looks like a misery. Forest fire is one of the factors that severely affects the forest biodiversity. Burning actions in a forest affects not only flora and fauna but also soil properties changed due to the forest fire. In summer season on sloppy topography forest fire originates in tropical forests. While in coniferous forests, forest fire outbreaks during the resin extraction activities. More than 350 million hectares (ha) was estimated to be affected by vegetation fires globally. In India about 55% of forest area is prone to the fire. Fires can be natural or man- made, but manmade fire affects mostly. Several forest types and areas are more susceptible to forest fires because of suitable weather, topography and inflammable material. Forest fires adversely affect the soil, water, flora and fauna and disrupt the ecological functions. The new advances in fire control are remote sensing and GIS where real time information can be gathered about the fire break and immediate follow can be done. The chemicals (as borate, ammonium sulfate and ammonium biphosphate) are used for fire control and various other types of fire retardants are used to keep the fire under control. Forest fire changes the composition of vegetation, extinction of species, development of the various adaptations in unwanted plants. Nutrient cycle and soils are affected. Frequent forest fire events cause global warming. Forest fire needed to be controlled at initial stage and the large fires should not be allowed to occur, the modern techniques of monitoring, detection and control must be used for avoiding the large fires happenings.

“…These tools are also resistant to radio interference and other electromagnetic waves. It is worth mentioning that they usually show high sensitivity without causing contamination [23]. The researchers have already presented a lot of optical, fluorescence-based sensors that were successfully applied for heavy metal ion determination [24][25][26].…”

A novel fluorescence-sensing pathway for epinephrine (EP) detection was investigated. The ceramic-based miniature biosensor was developed through the immobilization of an enzyme (laccase, tyrosinase) on a polymer—poly-(2,6-di([2,2′-bithiophen]-5-yl)-4-(5-hexylthiophen-2-yl)pyridine), based on low temperature cofired ceramics technology (LTCC). The detection procedure was based on the oxidation of the substrate, i.e., in the presence of the enzyme. An alternative enzyme-free system utilized the formation of a colorful complex between Fe2+ ions and epinephrine molecules. With the optimized conditions, the analytical performance illustrated high sensitivity and selectivity in a broad linear range with a detection limit of 0.14–2.10 nM. Moreover, the strategy was successfully used for an EP injection test with labeled pharmacological samples.

“…In order to use the information that light can collect, it is essential to develop optical devices and sensors that are able to interact with optical degrees of freedom [2]. Optical sensors are used in a wide range of research and commercial applications and play a significant role in emerging technologies [2][3][4][5]. For example, systems that implement machine learning and artificial intelligence make large use of optical sensors and require new solutions to provide new functionalities and improved performance.…”

Photonic crystals are engineered structures able to control the propagation and properties of light. Due to this ability, they can be fashioned into optical components for advanced light manipulation and sensing. For these applications, a particularly interesting case study is the gyroid srs-network, a three-dimensional periodic network with both cubic symmetry and chirality. In this work we present the fabrication and characterization of three-dimensional cubically symmetric 8-srs photonic crystals derived from combination of eight individual gyroid srs-networks. We numerically and experimentally investigate optical properties of these photonic crystals and study in particular, the impact of cubic symmetry on transmission and optical activity (OA). Gyroid photonic crystals fabricated in this work can lead to the development of smaller, cheaper, and more efficient optical components with functionalities that go beyond the concept of lenses.
