“…Protective anti-soiling coatings provide a viable solution to the above problems [4][5][6][7][8][9][10]. The application of a non-stick barrier renders cohesion forces among same particles larger than adhesion forces among different particles and self-cleaning of dirty surfaces is facilitated.…”

“…Anti-soiling coatings may be an efficient solution to the above problem, since they can result in the reduction of O&M costs and water consumption while increasing the efficiency of a CSP solar collector field [4][5][6][7][8][9]. However, since the installed capacity is already enormous, anti-soiling coatings should be equally effective regardless if these are applied at the manufacturing stage or at an existing installation.…”

Power output of concentrated solar power systems (CSP) is strongly dependent on mirror reflectivity, which in turn, is affected by soiling and atmospheric conditions. Anti-soiling coatings can enhance efficiency of CSP plants while reducing operating and maintenance costs. Most of them however, suffer from poor endurance and performance. Transparent smooth coatings based on quaternarized silanes may be a viable approach in order to minimize energy losses attributed to soiling.

“…Thus, contributing to minimizing the efficiency decrease. Nowadays, investigations toward self-cleaning coatings have been also conducted for CSP systems to apply these coatings across all solar technologies, [127][128][129] but those for CSP reflectors are very limited in the market. Wette et al 128 have assessed the effectiveness of anti-soiling coatings compared to uncoated ordinary glass-surfaced material to improve CSP plants' reflectance.…”

During the twentieth and twenty-first centuries, the oil industry has been pivotal in influencing all countries’ geopolitical, economic, and human development strategies. Until recently, the debate was about peak oil and what would happen after oil finished. However, due to technological advances and hydraulic fracturing, shale oil formations have become economically viable due to the United States’ desire to achieve energy security to make a qualitative shift in the oil industry and the geopolitics of oil. Therefore, this paper deals with an economic model that illustrates the impact of oil price fluctuations to the shale oil and gas companies by analyzing the main determinants of continuity of shale oil and gas companies in production if global oil prices decline or rise. In addition, the study will investigate the effects of OPEC+ policy and Covid-19 on the future of shale oil industry. The study will discuss some future scenarios for global energy trends and predict what the shale industry will look like in the future. The study concluded the shale industry faces an internal destructive process (within the industry itself) and external (Renewable energy, OPEC and Covid-19). The stability of oil prices is a critical factor that promotes the shale industry's recovery. However, shale industry is expected to continue with low productivity growth rates and continuing government support for it.

“…Mirror lifetime is estimated at 25 years [3]. However, sometimes, it can be shorter than that due to quick degradation by the environmental conditions of the functioning site [4].…”

“…High wind speed is generally associated with erosion issues [5]. This degradation phenomenon directly affects the specularity of mirror surfaces by increasing the amount of diffuse reflectivity and therefore reducing the performance of the reflector in operation [4][5][6][7]. To evaluate the aggressiveness of a CSP potential site, this paper presents the work conducted to compare the durability of solar mirrors exposed in two different potential installation sites.…”

The durability of thick solar glass mirrors has been evaluated in this study by exposing samples at two potential exposure sites. Samples have been exposed for a period of 18 months at different orientations (North, South, East, and West) to evaluate the impact of orientation on the durability. The samples performance has been evaluated by measuring the specular reflectance of the glass samples before and after an appropriate cleaning process. In addition, the contact angle and the surface energy have been analysed. Obtained results show that mirror durability is very specific to the environmental conditions of the exposure site.
