Summary: Concentrating solar power (CSP) is a clean, renewable and sustainable energy source that has the potential to replace polluting fossil fuel technologies. Among CSP collectors, parabolic-trough collectors (PTC) are the most widely used technology. The use of nanofluids as heat transfer fluids (HTF) in CSP plants shows promise in improving their efficiency. This study focuses on the use of polycrystalline NiO nanowire-containing nanofluids as HTF in CSP plants, and evaluates their stability, rheological properties, and thermal performance. The results show that using nanofluids can significantly increase the overall performance of CSP systems.

Summary: Remarkable changes occur in the thermophysical properties of the heat transfer fluid used in concentrating solar power plants with the addition of Au nanoplates. The resulting nanofluids show enhanced physical properties, such as increased specific heat and thermal conductivity, without affecting density or dynamic viscosity. Computational models suggest that the performance of a concentrating solar power plant using these nanofluids could increase up to 35.1%, compared to 24.7% with conventional heat transfer fluid, without any negative effects or costly structural changes.

Summary: This study investigates the thermal transport and structural properties at the interface between molten sodium chloride and iron. The findings show that there is a strong enhancement of heat transfer at the metal-salt interface, which can be attributed to the adsorption of molten salt ions on the iron surface via van der Waals interactions. Increasing the metal-salt interactions strength also enhances the heat transfer rate.

Summary: Thermal energy storage allows for the generation of dispatchable electricity in modern CSP plants. The use of Solar Salt as a heat transfer fluid is important for success in solar tower systems. However, Solar Salt is not used in line-focusing CSP plants due to the risk of freezing. This study presents data on nitrate salt mixtures with lower melting points and higher thermal stability, which could be potential heat transfer fluids and storage media.

Summary: The present study analyzes the impact of using hybrid nanofluids on the performance of a novel solar PV/T system for maximizing overall efficiency. A new design was employed to transfer heat from the backside of a solar collector to water. Three-dimensional computational fluid dynamics simulation was performed using the finite volume method. The study examined the governing parameters including Reynolds number (100 <= Re <= 1500), heat flux (400 <= q <= 800), and different types of nanofluids, such as single or hybrid nanofluids. The results demonstrate a significant improvement in the PV/T system performance when using hybrid nanofluids.

Summary: In this study, GaN and InN nanosheets with dodecylamine (DDA) as surfactant were investigated as nanofluids for solar plants. The interactions between the sheets and the surfactants were studied using density functional theory. The most favorable interaction site was found to be between the metallic atom of the sheet and the N atom of the surfactant. The stabilizing role played by the electron pairing between the N atom of the surfactant and the metal atom of the sheet was confirmed by ELF, QTAIM, and DOS analysis. The highest isobaric specific heat values were obtained in the presence of diphenyl oxide as solvent, indicating the potential of GaN-DDA and InN-DDA systems in solar energy applications.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.
