A possibility of unprecedented architecture may be opened up by combining both vertical and in-plane heterostructures. It is fascinating to discover that the interlayer stress transfer, interlayer binding energy, and interlayer shear stress of bi-layer Gr/hBN with CNTs heterostructures greatly increase (more than 2 times) with increase the numbers of CNTs and both saturate at the numbers of CNTs = 3, but it causes only 10.92% decrease in failure strain.

Thermal oxidation has a significant effect on the durability of bitumen composites reinforced with carbon nanomaterials. However, the mechanisms of aging resistance and the effect of aging on the chemical properties, morphology, micromechanical properties, and rheology of bitumen with carbon nanomaterials are still unclear. This study investigated the mechanisms of aging resistance underlying the synergistic effects of graphene and carbon nanotubes (CNTs) on the durability of bitumen composites.

Strain sensing fabrics are able to sense the deformation of the outside world, bringing more accurate and real-time monitoring and feedback to users. However, due to the lack of clear sensing mechanism for high sensitivity and high linearity carbon matrix composites, the preparation of high performance strain sensing fabric weaving is still a major challenge. Here, an elastic polyurethane(PU)-based conductive fabric(GCPU) with high sensitivity, high linearity and good hydrophobicity is prepared by a novel synergistic conductive network strategy.

Nanoporous graphene (NPG), laterally bonded carbon nanoribbons, is a promising platform for controlling coherent electron propagation in the nanoscale. However, for its successful device integration NPG should ideally be on a substrate that preserves or enhances its anisotropic transport properties. Here, using an atomistic tight-binding model combined with nonequilibrium Green's functions, we study NPG on graphene and show that their electronic coupling is modulated as a function of the interlayer twist angle.

In silico methods are increasingly important in predicting the ecotoxicity of engineered nanomaterials (ENMs), encompassing both individual and mixture toxicity predictions. It is widely recognized that ENMs trigger oxidative stress effects by generating intracellular reactive oxygen species (ROS), serving as a key mechanism in their cytotoxicity studies. However, existing in silico methods still face significant challenges in predicting the oxidative stress effects induced by ENMs.
