“…A positively charged cathode electrode, a negatively charged anode electrode, along an electrolyte system that promotes the steady fow of electrons, make up a battery, which stores power produced by redox chemical reactions [193,194]. Most commonly used batteries are made primarily of inorganic metals such as copper, zinc, lithium, tin, nickel, and cadmium [195,196]. However, the majorities of these metals are not only expensive but also poisonous, and nonbiodegradable, and thus have an adverse efect on the environment.…”

Energy storage is a more sustainable choice to meet net-zero carbon foot print and decarbonization of the environment in the pursuit of an energy independent future, green energy transition, and uptake. The journey to reduced greenhouse gas emissions, increased grid stability and reliability, and improved green energy access and security are the result of innovation in energy storage systems. Renewable energy sources are fundamentally intermittent, which means they rely on the availability of natural resources like the sun and wind rather than continuously producing energy. Due to its ability to address the inherent intermittency of renewable energy sources, manage peak demand, enhance grid stability and reliability, and make it possible to integrate small-scale renewable energy systems into the grid, energy storage is essential for the continued development of renewable energy sources and the decentralization of energy generation. Accordingly, the development of an effective energy storage system has been prompted by the demand for unlimited supply of energy, primarily through harnessing of solar, chemical, and mechanical energy. Nonetheless, in order to achieve green energy transition and mitigate climate risks resulting from the use of fossil-based fuels, robust energy storage systems are necessary. Herein, the need for better, more effective energy storage devices such as batteries, supercapacitors, and bio-batteries is critically reviewed. Due to their low maintenance needs, supercapacitors are the devices of choice for energy storage in renewable energy producing facilities, most notably in harnessing wind energy. Moreover, supercapacitors possess robust charging and discharging cycles, high power density, low maintenance requirements, extended lifespan, and are environmentally friendly. On the other hand, combining aluminum with nonaqueous charge storage materials such as conductive polymers to make use of each material’s unique capabilities could be crucial for continued development of robust storage batteries. In general, energy density is a key component in battery development, and scientists are constantly developing new methods and technologies to make existing batteries more energy proficient and safe. This will make it possible to design energy storage devices that are more powerful and lighter for a range of applications. When there is an imbalance between supply and demand, energy storage systems (ESS) offer a way of increasing the effectiveness of electrical systems. They also play a central role in enhancing the reliability and excellence of electrical networks that can also be deployed in off-grid localities.

“…Waste management is one of the most painful problems today and is a priority in all developed countries. In Ukraine, as a result of the generation of large amounts of waste, this problem has become particularly acute [Ishchenko et al 2018]. As a result of industrial production in areas of location of various enterprises and places of extraction of minerals, and also quite often near settlements there are the centers of the industrial desert with insignificant vegetation and even without it.…”

This study is dedicated to the assessment of the heavy metal pollution of soil by determining the category of soil contamination due to the activities of mining and chemical enterprise. The X-Ray Diffraction method was used experimentally to determine the qualita-tive and quantitative composition of heavy metals and other inorganic elements in samples, soil pollution with heavy metals. Main sources of heavy metals in industrial waste are identified. The environmental pollution with some heavy metals (Sr, Cr, Pb, Zn, Cu, Mn) was assessed and exceeded the MPC. The ecological situation of soil contamination with heavy metals near tars on the study area territory is estimated in the category from permissible pollution to hazardous pollution. Soil near the phosphogypsum dump is classified as an acceptable, moderately dangerous, and dangerous category of soil pollution. It was established that at a distance of 20 m from the tailings the soils belong to the dangerous category of soil, closer to the tailings -to moderately dangerous. The value of the concentration coefficient indicates the activity of leaching processes (C c < 1) and accumulation (C c > 1) of substances in the genetic horizons of the soil. It is necessary to forecast the state of the environment in the area of influence of these enterprises to develop effective means of ensuring environmental safety.

“…Therefore, the problem of developing new sensors and new sensor materials is very topical [ 20 , 21 ], especially with respect to the concept of the Internet of Things [ 22 , 23 ]. There is a growing need to develop better and more accurate sensors because measurement accuracy also has economic [ 24 , 25 , 26 ], environmental [ 27 ] and medical effects [ 28 , 29 ]. In some branches of science, this need is mentioned as key for the next decade [ 30 , 31 ].…”

The results of the calculation of the energy band structure and luminescent research of CeF3 crystals are presented. The existence of two 5d1 and 5d2 subbands of the conduction band genetically derived from 5d states of Ce3+ ions with different effective electron masses of 4.9 me and 0.9 me, respectively, is revealed. The large electron effective mass in the 5d1 subband facilitates the localization of electronic excitations forming the 4f-5d cerium Frenkel self-trapped excitons responsible for the CeF3 luminescence. The structure of the excitation spectra of the exciton luminescence peaked at 290 nm, and the defect luminescence at 340 nm confirms the aforementioned calculated features of the conduction band of CeF3 crystals. The peculiarities of the excitation spectra of the luminescence of CaF2:Ce crystals dependent on the cerium concentration are considered with respect to the phase formation possibility of CeF3.
