This study presents experimental performance and model analysis of a parabolic trough collector (PTC) system designed for industrial heating applications. Thus, a prototype of a PTC with 1.81m2 reflective aperture area, 90o rim angle and a concentration ratio of 14.41 is presented. The reflector is made of 2m2 anodized aluminium mirror with high light reflectance value of 0.95. The re-ceiver, or heat collection element (HCE), is a 2m long tube made from SUS304 (SS304) stainless steel, which is enclosed within an external layer of borosilicate glass envelope. The receiver exhibits an exceptionally high surface absorptance of 0.96 and transmittance value of 0.92. The tracking system is based on a universal sensory solar tracker controller designed to be used with permanent magnet DC motors, and with high tracking accuracy and great electrical ca-pabilities. Initially, a simulation model of the PTC is developed using System Advisor Model (SAM) software. Then, a PTC prototype sys-tem test setup is established under outdoor weather conditions at Kimuka, in Kajiado, Kenya (latitude 1.418426°S and longitude 36.59749°E), to validate the model using experimental and meteoro-logical data measured under clear-sky condition and cloudy weather. The deviations between experimental and simulation results on the clear-sky day are 5.6% for useful heat gain, 1.89% for optical effi-ciency, and 1.42% with RMSE of 0.20% for instantaneous thermal efficiency, respectively, demonstrating good agreement. For the cloudy day, the observed deviations between experimental findings and simulation results are 9.8% for useful heat gain, 1.05% for opti-cal efficiency, 3.32% with RMSE of 0.57% for instantaneous thermal efficiency, respectively, also indicating a satisfactory level of agree-ment. Based on these results, SAM simulation model can be consid-ered as effective in forecasting the thermal and optical performance of PTCs across various operational scenarios in Kenya. At the same time, the cost of the PTC is about US$185/m2 of aperture area, and lies within a competitive range in comparison to competitors in the market.

“…The layers used were 10 nm of Al, 26 nm of aSi, 5 nm of ITO, and 5 nm of air. Farzaneh et al [51] outlined the benefits of Al are lighter, has splendid electrical conductivity, considerable surface reflectivity and is highly corrosion-resistant. Hence, Al is vastly qualified as a back layer of the aSiSC model and extensively coupled with the ITO layer, which can diminish the optical loss.…”

As the world population rises, energy needs are become critical. Using photovoltaic technologies like amorphous silicon solar cells (aSiSC) to harvest solar power might benefit global concern. Previous research claimed that aSiSCs were modest short-wavelength absorbers. Quantum dot (QD) may be applied to the aSiSC to enhance optical absorptions and electric fields as the QD’s bandgap is tunable, which can cover a broader electromagnetic range. This study aims are to design the 3D aSiSC with QD on the model and to investigate the optical absorption peak, electric field profiles, and light-matter interaction of the models via COMSOL Multiphysics software. From the base model, the optical absorption improved from 736 nm at 41.827% to 46.005% at 642 nm for the aSiQDSC model which developed with 0.5/3.0 nm radius of core/shell cadmium selenide/zinc sulphide (CdSe/ZnS). This study proceeded combining rectangular nanosheets gold and silver nanoantenna (Au and Ag NA) with various gap g of NA to the aSiQDSC models where g = 0.5 nm Ag NA model was presented the higher optical absorption of 47.246% at 650 nm, and electric fields of 2.53×1010 V/nm. Computationally, this ultimate design is ecologically sound for solar cell applications, which allow future direction in renewable energy research and fabrication

“…Figure (2) shows that the drop can lie on a surface and air composite state defined by the solid fraction (f), which is the fraction of solid in contact with the liquid droplet. With the Cassie-Baxter model, the apparent contact angle (θ c ) related by Young's contact angle (θ) and solid fraction (f) is given as [38]: Wenzel and Cassie-Baxter theory of droplet formation on a rough surface suspension on a solid/air composite [38] As seen in this equation, apparent contact angle (CA) is increased by decreasing the solid fraction (f) in high porous surface and increasing the CA of the smooth flat surface (θ) in low surface energy and it is going to be a superhydrophobic surface.…”

Improvement of corrosion resistance is a main challenge in surface and corrosion engineering. Water is a main part of corrosion mechanism, and the omission of this part will be helpful. "y mimicking from nature, superhydrophobicity is a helpful method to decrease corrosion and water presence on the surface. Superhydrophobic surface and coating is a new type of coating that extension in recent decade and increase application of this area every day. These type of coatings are using on widespread of applications such as solar panels, displays, windows, paints and fabrics to obtain water-proof, anticorrosive, self-cleaning and stain-resistant surfaces. Many different studies have been reported to produce superhydrophobic surfaces from many diverse materials polymers, metals and other inorganic materials, composites, textiles, paper . In this chapter, recent developments in the application of superhydrophobic coatings for corrosion protection of aluminum and copper alloys will be discussed. This chapter includes new production methods, theoretical works, and the limitations of superhydrophobic coatings.
