In these circumstances, we must search forward to ‘green energy’ for power generation. Green energy means environment-friendly and non-polluting energy (inclusive of solar, biomass, wind, tidal, etc.). Concentrated Solar Power (CSP) generation is one of the maximum promising candidates for mitigating the destiny power crisis. The extracted energy from CSP technology may be very clean, dependable, and environmentally friendly. A review of the parabolic trough collector (PTC) which is one of the CSP technology with a focus on the components, the working principle, and thermal properties of the parabolic trough collector. Also, this study explains the parabolic trough power plants with tracking systems, from the other hand, evaluates the effects of using many types of reflectors and multi kinds of working fluids on the performance of the parabolic trough collector (PTC), in addition of that study presents the use of PTCs in many applications.

“…Molten salt is still a competitive as a working fluid in the receiver, and both with its dual role as HTF and TES, and its low price, it is the most used HTF in central tower CSP systems today [40]. Water/steam can connect with the steam turbine directly, that saves cost of equipment such as the heat exchanger, but it has a difficult in integrating with storage system [41][42][43]. Exergy destruction in absorption was large during the boiling process because of the low external wall temperature, while exergy losses in external radiation are low [44][45][46][47].…”

While fossil fuel sources have declined and energy demand has increased, in addition to the climate change crisis, the world turned to using renewable energies to get its energy. Concentrated solar power (CSP) is one of the main technologies used for this purpose. This study aims to compare the different concentrated solar power technologies in terms of their efficiency, cost, concentration ratio, and receiver temperature. Results showed that technologies were arranged according to temperatures from high to low as follows; the parabolic dish reflector, central receiver collector, linear Fresnel reflector, and parabolic trough collector. According to cost, the parabolic dish reflector has the highest price, while the linear Fresnel reflector has the lowest price. Also, the parabolic dish reflector has the highest efficiency among the others, followed by the central receiver collector, then the linear Fresnel reflector, and the parabolic trough collector respectively. Additionally; the study represented that point-focus devices have a high percentage of concentration ratio than line-focus devices. Finally, in order to exploit these sources throughout the day, it is recommended to use phase change materials to store the excess thermal energy as a positive and effective approach to solving the energy problems.

Moreover, the nanomaterials Er 2 O 3 and NiO are individually thought to be multifunctional because of their prestigious physio-chemical properties [25][26][27][28][29][30][31][32][33][34], and have a wide range of applications in biomedical [34][35][36][37], chemical [38,39], thermal conductivity [40,41], pharmaceutical [42][43][44][45], sensing [15,24,46,47], electrochromic [48,49], energy storage [50][51][52], agri-science [53][54][55], and catalysis fields [56][57][58][59][60][61][62].…”

Generally, our ecosystem is continuously contaminated as a result of anthropogenic activities that form the basis of our comfort in our routine life. Thus, most scientists are engaged in the development of new technologies that can be used in environmental remediation. Herein, highly calcined binary metal oxide (Er2O3@NiO) semiconductor nanocomposite (NC) was synthesized using a classical wet chemical process with the intention to both detect and degrade the toxic chemicals in an aqueous medium using a novel electrochemical current–potential (I–V) approach for the first time. Optical, morphological, and structural properties of the newly synthesized semiconductor NC were also studied in detail using FT-IR, UV/Vis., FESEM-EDS, XPS, BET, EIS, and XRD techniques. Then, a modified glassy carbon electrode (GCE) based on the newly synthesized semiconductor nanocomposite (Er2O3@NiO-NC/Nafion/GCE) as a selective electrochemical sensor was fabricated with the help of 5% ethanolic-Nafion as the conducting polymer binder in order to both detect and electro-hydrolyze toxic chemicals in an aqueous medium. Comparative study showed that this newly developed Er2O3@NiO-NC/Nafion/GCE was found to be very selective against m-tolyl hydrazine (m-Tolyl HDZN) and to have good affinity in the presence of other interfering toxic chemicals. Analytical parameters were also studied in this approach to optimize the newly designed Er2O3@NiO-NC/Nafion/GCE as an efficient and selective m-Tolyl HDZN sensor. Its limit of detection (LOD) at an SNR of 3 was calculated as 0.066 pM over the linear dynamic range (LDR) of our target analyte concentration (0.1 pM–0.1 mM). The limit of quantification (LOQ) and sensitivity were also calculated as 0.22 pM and 14.50 µAµM−1cm−2, respectively. m-Tolyl HDZN is among the toxic chemicals in our ecosystem that have lethal effects in living beings. Therefore, this newly designed electrochemical sensor based on semiconductor nanostructure material offers, for the first time, a cost-effective technique, in addition to long-term stability, that can be used as an alternative for efficiently probing other toxic chemicals in real samples.
