Summary: The development of composite materials with functional additives proved to be an effective way to improve or supplement the required properties of polymers. In this study, mesoporous silica (SBA-15) with different pore sizes were used as functional additives to prepare SBA-15/PF (phenolic resin) nanocomposites. The results revealed that the pore sizes of SBA-15 have a significant effect on the resulting SBA-15/PF hybrid and SBA-15/PF nanocomposites, with enhanced thermal and frictional properties.

The optimal conditions for adsorption were determined, and the results showed that the functionalization of the adsorbent surface increased the adsorption efficiency and capacity. The highest adsorption capacity for Cr(VI) was about 50 mg/g.

Summary: In this study, the focus was on exploring new methods for heat dissipation in micro devices by investigating the thermophysical properties induced by surface phonon polaritons in multilayer systems. Results showed that the specific heat induced by polaritons was much smaller than that contributed by phonons, while the thermal conductivity along the in-plane direction could be significantly higher, suggesting potential applications in heat dissipation and long-distance thermal energy transport. The expansion coefficient caused by polaritons was also found to be much lower than that caused by phonons, which could benefit the enhancement of heat transfer using polaritons.

Summary: The kinetics of Al-Ni and Cu-Ni nanodroplets spreading on a Cu substrate with a temperature difference between them were studied using molecular dynamics simulations. The simulations revealed that significant dissolution reactions occurred in both systems and no precursor film was formed during spreading. The spreading rate of nanodroplets in the Al-Ni/Cu wetting systems increased when they contained fewer Ni atoms, while in the Cu-Ni/Cu wetting systems, the spreading rate remained unchanged regardless of the Cu to Ni ratio due to their similar lattice constants. The simulations also showed that local solidification occurred in the later spreading stage due to the temperature gradient, hindering the spreading process.

Summary: Developing advanced high-temperature thermal storage systems is crucial for improving the efficiency and reducing the costs of solar thermal storage. Two typical systems composed of Cu as the matrix and Sn as the phase change material (PCM) were explored in this study: a 3D structure system with embedded Sn particles and a 2D structure system with embedded Sn wires. The thermophysical properties of PCM and matrix were derived theoretically, and used to estimate the energy storage ability and investigate the influence of structure on heat transfer efficiency. Results showed that the 3D structure system was a better choice due to its larger specific surface area, sensitive heat capacity, and thermal conductivity. The thermal conductivity of the system decreased exponentially when the feature size of the PCM decreased below a critical value, while the heat storage capacity increased linearly. Moreover, when the feature size of the Sn geometry was below a critical value, the Cu matrix could not improve the effective thermal conductivity of the whole system.
