Summary: This work focuses on the development of CF@Fe2O3/(BN/SR) composites with excellent thermal conductivity, electromagnetic interference (EMI) shielding performance, and electrical insulation properties. The sandwich structure of CF@Fe2O3/(BN/SR) composites contributes to effective EMI shielding by absorption-reflection-reabsorption of electromagnetic waves, while BN/SR and CF@Fe2O3 layers enhance thermal conductivity and electrical insulation, respectively. The composites show higher performance in terms of thermal conductivity, EMI shielding effectiveness, volume resistance, and breakdown strength compared to conventional CF/(BN/SR) composites. The CF@Fe2O3/(BN/SR) composites also exhibit better cooling effect than commercial silicon grease in computer testing platforms, indicating promising applications in electronics.

Summary: This study systematically investigated the effects of MgO on the shrinkage and crack resistance of face slab concrete. It was found that adding the appropriate amount of MgO can compensate for a certain proportion of shrinkage and improve crack resistance, with the reactive MgO (M60) performing the best and the weak reactive MgO (M300) reducing crack resistance.

Summary: This study investigates the frequency dispersion mechanism of negative permittivity in carbon nanotubes (CNTs)/epoxy composites. The Debye model is used to describe the dielectric relaxation when the CNT content is below the percolation threshold, while the Drude model explains the negative permittivity resulting from the plasma oscillation of free electrons in CNT networks above the percolation threshold. A novel Debye-Drude model is proposed to explain the low-frequency dispersion and weakly negative permittivity observed when the CNT content is slightly higher than the percolation threshold.
