Summary: A low power remote plasma-enhanced chemical vapor deposition is used to directly grow graphene nanowalls, which effectively improves the growth rate and reduces defects. Hafnium oxide, employed as an interfacial layer, acts as an electron-blocking and hole transport layer, minimizing recombination and reducing dark current. The fabricated photodetector shows excellent performance with low dark current, high responsivity, high specific detectivity, and high external quantum efficiency.

Summary: An effective strategy of introducing micro-nano layers with multi-walled carbon nanotube (MWCNT) networks between titanium and PEEK layers via electrophoretic deposition was proposed to enhance the interfacial adhesion of CF/PEEK-titanium hybrid laminates. The optimal deposition condition was explored, resulting in a significant increase of interlaminar shear strength compared to the sandblasted-only case. Micromorphology, apparent contact angle, and roughness analyses provided insights into the enhancement mechanisms and demonstrated the excellent interlaminar properties of the hybrid laminates.

Summary: In this study, graphene oxide (GO) with different oxidation degrees was synthesized and grafted onto the surface of glass fiber fabric (GFf) for the fabrication of GFf/epoxy laminated composites. The interlaminar and interfacial properties as well as interlaminar microstructure of the composites were investigated. The results showed that the dispersion state and strengthening/toughening efficiency of GO in the composites were influenced by the various oxygen-containing functional groups on the GO surface due to oxidation degrees, thus affecting the composites' interlaminar and interfacial adhesion. The optimal oxidation degree of GO was achieved by using a moderate weight ratio of oxidation agent (KMnO4)/graphite (2:1), which improved the interlaminar shear strength, work of fracture, storage moduli, fiber/matrix interfacial adhesion, and glass-transition temperature of the composites.

Summary: In this study, a 120 mu m-thick freestanding film composed of vertically aligned, covalently bonded graphene nanowalls (GNWs) was grown by mesoplasma chemical vapor deposition. With silicone filling, the fabricated adhesive TIMs showed a high through-plane thermal conductivity of 20.4 W m(-1) K-1 at a low graphene loading of 5.6 wt%, achieving cooling efficiency approximately 1.5 times higher than commercial TIMs. The TIMs strike a balance between high thermal conductivity and small bond line thickness, providing superior cooling performance for high-power LED chips.

Summary: The interfacial structure and bonding strength of graphene-Al interface with different vacancy defect types were investigated by first-principle calculations. The interfacial shear strengths of defect-free, single-vacancy, and double-vacancy were 0.02 GPa, 6.8 GPa, and 8.5 GPa, respectively. A calculation model for shear strength of graphene-Al interface with different defect contents was established and a method to estimate the shear strength based on Raman characterization of graphene defects was proposed.

Summary: The study investigates the impact of interfacial interaction between 2D materials and the substrate on the electronic properties, and quantitatively analyzes the orientation-dependent facet topographies observed on graphene using electron backscatter diffraction and atomic force microscopy. Molecular simulations reveal that apart from anisotropic interfacial energy, graphene strain plays a critical role in forming the observed topographies. These findings are also applicable to other 2D/3D heterostructures.

Summary: The study focused on enhancing magnesium alloy composites by grafting different amounts of carbon nanotubes onto carbon fiber surfaces. Moderate interlaminar shear strength was found to be beneficial for improving tensile properties, with the presence of carbon nanotubes delaying crack propagation and increasing energy consumption to enhance strength. Adjusting the quantities of grafted carbon nanotubes optimized crack propagation paths and affected stress distribution, crack initiation, and propagation.

Summary: In this study, multi-walled carbon nanotubes (CNTs) were grown in-situ on the surface of carbon fibers (CFs) at low pressure using vertical chemical vapor deposition (CVD). The resulting hierarchical composite material based on epoxy resin showed significantly improved interlaminar shear strength (ILSS) and fracture behavior, attributed to the enhanced adhesion of fibers and resin, as well as the constrained molecular movement and strong anchoring interaction provided by the CNTs.
