Summary: Silver composites with an inhomogeneous structure were prepared using spark plasma sintering (SPS) with carbon nanotubes reinforced Cu foams as the 3-dimensional skeletons. The composites exhibited enhanced strength, good ductility, and high conductivity, with the formation of diffusion layers after heat treatments leading to further improvements in strength but slight reductions in ductility and conductivity. The structures, properties, and possible mechanisms of the composites were studied and discussed in this paper.

Summary: The orientation and dispersion of nanoparticles greatly affect the conductivity and mechanical properties of nanocomposites. This study investigates the influence of different molding methods and shear conditions on the dispersion and orientation of carbon nanotubes (CNTs) in polypropylene/CNTs nanocomposites. It is found that high dispersion of CNT agglomerates hinders the formation of a conductive network, while increased orientation of CNTs results in current only flowing in the orientation direction.

Summary: High modulus, high thermal conductivity, low coefficient of thermal expansion, high electrical conductivity, self-lubricating characteristics and low density make carbon nanotubes (CNTs) one of the best reinforcing materials for nano composites in various applications. This study focuses on the tribological behavior of CNTs-reinforced composites, including metal matrix composites (MMCs), polymer matrix composites (PMCs), and ceramic matrix composites (CMCs). The study discusses the tribological characteristics, production challenges, and recommendations for dispersing CNTs and improving the wear resistance of composites. It is discovered that ball milling affects the CNTs' outer walls, but ultrasonication and functionalization can eliminate this adverse effect. The addition of CNTs to composite matrices improves wear resistance, reduces wear volume, decreases the coefficient of friction, and provides a self-lubricating effect.

Summary: In this study, carbon nanotubes (CNTs) reinforced double-layered Cu-Ni composite foams were prepared through chemical plating and electrodeposition. The microstructure characterization showed a uniform dispersion of CNTs in the metal layers even after heat treatments. Property testing demonstrated significant improvements in compressive strength, energy absorption capacity, and electromagnetic shielding effectiveness of the Cu-Ni/CNT foams compared to Cu-Ni foams. Heat treatments resulted in an interdiffusion of Cu and Ni layers, increasing compressive strength and slightly decreasing average shielding effectiveness. The possible mechanisms of these property changes were discussed.

Summary: This paper investigates the use of carbon nanotubes (CNTs) and nano-SiO2 in cement composites. The results show that the mechanical properties of the cement composites are significantly improved with the appropriate incorporation of CNTs/SiO2 fillers. Microscopic observations reveal that CNTs enhance the performance of cement composites through crack-bridging, debonding, and pull-out behaviors. Hydration analysis indicates that CNTs/SiO2 fillers accelerate the cement hydration process through the nano-nucleating action. The reinforcing mechanisms of CNTs/SiO2 fillers can be attributed to the synergistic effects of CNTs dispersion stability, the nucleating effect of nano-additives, and the pozzolanic reaction by nano-SiO2.

Summary: Buildings consume a significant amount of energy globally, and researchers are striving for energy conservation within buildings. Solar systems incorporating phase change materials (PCMs) for thermal storage have great potential. Existing research shows that PCMs can be configured using either passive or active techniques when coupled with solar thermal energy, with active heat exchangers being more efficient and cost-effective. For most domestic buildings, organic PCMs with phase change temperatures around 42°C and thermal conductivities up to 0.56 W/m.K are most suitable. Hybrid systems and annual savings per year are key factors to consider. This review provides valuable insights for designers and researchers in coupling PCMs with solar thermal energy in non-industrial buildings. Rating: 8/10.

A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
