Having kilometers of asphalt road, yet with this heat going to waste, an attempt has been made in this research to extract the road's renewable energy heat. The purpose of the experiment is to compare the energy and exergy efficiency of various materials of asphalt solar water heaters (ASWH), as well as heat transmission through the water tube and how friction affects exergy destruction. The water flow rate of one ASWH was 0.01 kg/s, while that of the other was 0.02 kg/s. Each ASWH has an area of 0.5 square meters. The copper tube is buried 10 mm deep in the asphalt. 15 degrees is the angle of inclination. The results indicate that the energy and exergy efficiencies are reasonably high for the water flow rate of 0.02 kg/s. Depending on the water flow rate, asphalt temperature, and sunlight intensity, the energy and exergy efficiencies changed from 32% to 65% and 5.8% to 16%, respectively. The water flow rate is an essential parameter for estimating the internal convective heat transfer coefficient and Reynolds number in order to calculate the friction factor in the copper tube based on internal convection heat transfer. In contrast, the friction factor is a consequence of the pressure loss and exergy degradation induced by friction.

In this study, the thermal touch comfort of ceramic tiles was investigated. For this purpose, energy analysis was made for the heat transfer during touch and the surface temperature during touch was calculated. It is explained how the thermal inertia phenomenon contributes to the calculation of the surface temperature. It has been revealed why ceramic tiles feel cold when touched. In order to examine the tactile comfort, the structure of the human skin and the mechanism of feeling the temperature are shown. In addition, for other coating materials at the same temperature as the ceramic tile, the surface temperatures during touch were calculated and compared. Previous studies to increase thermal comfort in ceramic tiles are discussed. It was calculated how much the thermal comfort increased as a result of coating the ceramic tile with a polymer material. The applicability of the coating option and how close it is to the goal of increasing thermal comfort are discussed. Thus, by calculating how much the coated ceramic tile improves the thermal comfort, a basic study has been put forward to evaluate the thermal comfort improvements to be made on many surfaces used as coating elements in buildings and touched by people.

This research describes the thermopower and electric conductivity of CdTe films produced using thermal evaporation technology; the energy activation value of this electrical and thermoelectrically properties are estimated. CdTe sheets have an electrical resistance of about (107. cm). Conductivity was studied, and it was found that the electrical conductivity increased with temperature. At low temperatures, there are two values of activation energy $(Ea1=0.337 eV)$ because of this dependence, but at high temperatures, $(Ea2 = 0.702 eV)$ is the only value of activation energy. The Seebeck coefficient (thermopower) was researched to find that it was temperature-dependent, and it was found that, as the temperature increased, the Seebeck coefficient decreased. The experiment results on thermoelectric power were summarized in a two-paragraph statement. The activation energy was measured to be $(ES = 0.561 eV)$, and the CdTe film was shown to be p-type conductive.

Thermal energy storage has attracted significant attention, with a wide range of phase change materials (PCMs) being used due to their beneficial physical and chemical properties. While nitride-based salt PCMs are commonly applied for thermal heat storage, their latent heat storage capacity remains limited. This study enhances the performance of nitride-based salts for thermal energy storage by incorporating monolayer boron nitride, improving both thermal conductivity and latent heat storage capacity. The novel blend of Sn₃N₂-LiNO₃-NaCl/Monolayer boron nitride is characterized by high specific heat capacity, a high latent heat value, and a low phase change temperature, making it an excellent candidate for thermal energy storage. The addition of monolayer boron nitride to the PCMs significantly enhances the thermal conductivity, increasing it from 1.468 W/m·K to 5.543 W/m·K. Of note, these nitride-based ternary salts do not chemically react with one another; their interaction occurs purely through mixing to improve thermal properties. The novel blend also demonstrates remarkable thermal stability, with a decomposition rate of just 0.5% at 600°C, a melting temperature of 150°C, and a solidification temperature of 130°C. The specific heat capacity of the ternary salt reaches a maximum of 3.5 J/g·°C, indicating a higher thermal heat flow rate, as well as increased charging and discharging rates. The heat storage capacity of the composite PCM (CPCM) is 600 kJ/kg at 600°C, and the combination of these PCMs prolongs thermal energy storage duration. The ternary salt demonstrates outstanding thermal stability, maintaining performance over 100 cycles without significant mass reduction. In addition, the diffusion of the ternary salt into the monolayer's pores further enhances its effectiveness. Simulation analyses are performed using Anaconda-based Jupyter Notebook with Python.
