Summary: In this paper, the application of new structure and loading Graphene nanoparticles to enhance thermal storage systems has been studied. Aluminum layers were used in the paraffin zone, which has a melting temperature of 319.55 K. The paraffin zone was located in the middle section of a triplex tube, with uniform hot temperatures (335 K) applied to both walls of the annulus. Three container geometries were tested by changing the angle of fins (alpha = 7.5 degrees, 15 degrees, and 30 degrees). A homogeneous model with uniform concentration of additives was assumed for property prediction. The results show that loading Graphene nanoparticles decreases the melting time by about 4.98% when alpha = 7.5 degrees, and the impact of phi improves by about 5.2% when the angle is reduced from 30 degrees to 7.5 degrees. Furthermore, as the angle decreases, the melting period decreases by approximately 76.47%, which is associated with an increase in driving force (conduction) in geometries with lower alpha.

Summary: In this paper, the study of fuzzy differential equations (FDEs) in fuzzy calculus is discussed, which provides a proper model to address real problems with uncertainties. Specifically, a class of fuzzy differential equations (FFDEs) with non-integer or variable order (VO) is considered. The main problem is converted to a new problem by utilizing the r-cut representation and is solved using operational matrices (OMs) based on shifted Legendre polynomials (SLPs), leading to a system of nonlinear algebraic equations. The accuracy of the proposed technique is confirmed with an example.

Summary: This study applies numerical techniques to assess the integration of twisted tapes in different cross-sectional tubes of Photovoltaic/Thermal (PV/T) collector units, and the impact on system performance. Computational fluid dynamics is used to evaluate PV/T systems with cylindrical, rectangular, and triangular cross-sectional tubes, with and without twisted tapes. Various pitch-to-width ratios (YD) of twisted tapes and total inlet mass flow rates are considered. The analysis of energy and exergy is carried out to evaluate system performance. The results show that the triangular cross-sectional tube is optimal without twisted tapes, but the cylindrical tube with twisted tapes outperforms other designs in terms of electrical and thermal aspects. The addition of a twisted tape in the cylindrical tube increases electrical efficiency by 7.2% and 9%, respectively. Furthermore, integrating twisted tapes with the lowest pitch-to-width ratio reduces surface temperature by 3.2℃ and 17.55℃ compared to systems with cylindrical tubes and PV alone.

Summary: Regarding the thermal management of the storage unit, one possible solution is to use an extended surface made of highly conductive metallic materials. This study suggests four different arrangements of the system by changing the number and thickness of plates, and solid matrix made of Silicon Carbide, Aluminum, and Stainless Steel. Additionally, loading alumina nanoparticles improves the heat absorption of the phase change material. Increasing the number of radial plates and reducing their thickness enhances heating penetration. The best case in terms of melting speed is achieved when using 40 plates with a thickness of 0.5 mm made of SiC material, resulting in a 87.84% reduction in melting time compared to the worst case.

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.
