Summary: The transport capabilities of copper selenide (Cu2Se) and its GO/MWCNT nanocomposites were studied using a cost-effective chemical reduction method and a simple mechanical grinding process. The addition of GO/MWCNT increased the power factor, with maximum values of 881 & mu; W/mK2 and 1120 & mu; W/mK2 for Cu2Se-GO and Cu2Se-MWCNT at 450 degrees C, respectively. The Cu2Se-MWCNT composite exhibited a thermopower that was about 90% greater than the bare Cu2Se. This study provides a method for producing carbon-related thermoelectric composites and enhancing thermoelectric performance by increasing the power factor.

Summary: This research investigates the synergistic effects of multi-walled carbon nanotubes (CNT) and in-situ synthesized titanium carbide (TiC) on the mechanical performance of aluminum hybrid composites. The study finds that the reinforcement with CNT and TiC significantly improves the micro-hardness, tensile strength, and impact strength of the composites. However, it also results in a decrease in the impact strength. Further analysis reveals the presence of CNT pull-out and CNT bridging effects from the tensile fractography of the composites.

Summary: In this study, PEEK/PTFE composites reinforced with CFs and Gr were fabricated and their friction and wear properties were investigated. It was found that the introduction of CFs significantly improved the tribological properties, but the addition of CFs alone resulted in higher friction coefficient. However, a combination of CFs and Gr showed a synergistic effect in improving the friction-reducing and anti-wear abilities of the composites. The mechanisms behind the improved tribological properties were discussed based on the analysis of the worn surfaces and tribofilms.

Summary: In this study, the tribological response of two polymeric materials against differently coated surfaces was tested, and the wear mechanism of each coupling was identified. The results showed that a PTFE based material, reinforced with glass fibers and a solid lubricant, offered better overall performance than unreinforced polyketone. While the behavior of the PTFE matrix composite was generally worse, it could be used without reinforcing fillers. The formation of a transfer-film on the counter-surfaces was found to be important in preventing further wear of the polymer, but had opposing effects on the friction coefficient for the two materials.

Summary: Boron carbide (B4C) ceramic hollow microspheres with enhanced mechanical properties were obtained by adding 2 wt% carbon nanotubes (CNTs), resulting in reduced sensitivity to hydrodynamic instability in high-temperature and high-pressure environments during fusion reaction and improved fuel efficiency. Additionally, the high surface finish and strength of B4C hollow microspheres can effectively reduce the impact of hydrodynamics instability on implosion and enhance the gain of the target in inertial confinement fusion.

Summary: The study focuses on enhancing the mechanical properties of Fiber-metal laminates (FMLs) by adding multi-walled carbon nanotubes (MWCNTs) to a polymer matrix, leading to a significant improvement in interface performance. The van der Waals energy, total energy, and interfacial interaction energy all showed varying trends with different diameters of MWCNTs, eventually stabilizing and indicating an improvement in interface properties. At an average MWCNT diameter of 8 nm, the interface fracture energy increased by nearly 180% compared to the material without MWCNTs.
