As a novel combined environmental toxicology technique to reduce the environmental hazards to humans, the utilization of agriculture waste as a novel waste material recycling process in aluminum metal matrix composites has been getting more attention to fabricate and improve the properties of this kind of composites. In this study, a new kind of metal matrix composite reinforced with rice husk ash particles has been fabricated. In the first step, the Al base composites reinforced with rice husk ash particles were fabricated via the compa casting process and the second step was the study of their mechanical, electrical, physical and wear properties. It also highlights the current application and future potential of agriculture-industrial waste-reinforced composites for various applications with a focus on material manufacturing in vessels, automobiles and other construction industries. Also, the annealing was performed after ARB on fabricated composites. Different elongation can happen during heating and annealing since the thermal expansion coefficients of composite samples are not equal and could weaken the strength of the interface. The examination unveiled that composites containing 10% by weight of RHA particulates exhibit superior mechanical and wear resistance compared to monolithic samples. Moreover, the average Vickers hardness of the samples increased from 154.0 to 168.0 for monolithic and 10% RHA samples, respectively, marking a 9% improvement.

Photovoltaic thermal (PVT) systems offer an attractive prospect to produce thermal and electricity powers when used as the building envelope. The present numerical analysis is performed intending to evaluate the thermal, electrical, and overall efficiencies of a PVT unit with a corrugated serpentine absorber tube filled with the A(2)O(3)/water nanofluid. The influence of Reynolds number (Re) and nanoparticle concentration (w) on the performance metrics of the system is analyzed. The result indicated that within the w range of 0-1%, the increment in Re from 500 to 2000 diminishes the PV panel temperature by 3.13-3.32%, while pressure drop boosts by 5480.95-5580.06%. The increase in w from 0% to 1%, however, declines the PV panel temperature and pumping power by 0.43-0.62% and 1.25-2.97%, respectively. The range of changes in the overall efficiency was 60.38-90.45%, the maximum and minimum of which belong to Re = 2000&w=1% &w =1% and Re = 500&w=0%, &w =0%, respectively. The results of artificial neural network (ANN) modeling presented an accurate function for estimation of the overall efficiency of the studied PVT unit based on the Re and w with the R-squared coefficient of determination of R-2 = 0.99602.
