“…27,67 To avoid aggregation and restacking, preparation techniques to assemble MXenes are shown in Fig. 3 including 3D hierarchical structures, 68,69 hybrids and nanoparticle/ion decoration, [70][71][72] and surface functionalization. 73 Such a restructuring of MXene may avoid restacking and aggregation by physically placing MXene sheets far from each other, thus utilizing the high surface area of 2D MXene.…”

This paper provides a summary of the recent developments with promising 2D MXene-related materials and gives an outlook for further research on gas sensor applications. The current synthesis routes that are provided in the literature are summarized, and the main properties of MXene compounds have been highlighted. Particular attention has been paid to safe and non-hazardous synthesis approaches for MXene production as 2D materials. The work so far on sensing properties of pure MXenes and MXene-based heterostructures has been considered. Significant improvement of the MXenes sensing performances not only relies on 2D production but also on the formation of MXene heterostructures with other 2D materials, such as graphene, and with metal oxides layers. Despite the limited number of research papers published in this area, recommendations on new strategies to advance MXene heterostructures and composites for gas sensing applications can be driven.

“…For a wide variety of envisioned applications in space exploration, artificial muscles, and ballistic armour, materials must be significantly stronger, stiffer, and lighter than those currently available. Carbon nanotubes (CNTs), initially discovered in 1991, have attracted extensive attention by offering extraordinary mechanical properties, including stiffness (~ 1 TPa), strength (~ 120 GPa) and resilience (~ 15% strain to failure) [2][3][4][5].…”

Carbon nanotube (CNT) networks enable CNTs to be used as building blocks for synthesizing novel advanced materials, thus taking full advantage of the superior properties of individual CNTs. Multiscale analyses have to be adopted to study the load transfer mechanisms of CNT networks from the atomic scale to the macroscopic scale due to the huge computational cost. Among them, fully resolved structural features include the graphitic honeycomb lattice (atomic), inter-tube stacking (nano) and assembly (meso) of CNTs. On an atomic scale, the elastic properties, ultimate stresses, and failure strains of individual CNTs with distinct chiralities and radii are obtained under various loading conditions by molecular mechanics. The dependence of the cohesive energies on spacing distances, crossing angles, size and edge effects between two CNTs is analyzed through continuum modeling in nanoscale. The mesoscale models, which neglect the atomic structures of individual CNTs but retain geometrical information about the shape of CNTs and their assembly into a network, have been developed to study the multi-level mechanism of material deformation and microstructural evolution in CNT networks under stretching, from elastic elongation, strengthening to damage and failure. This paper summarizes the multiscale theories mentioned above, which should provide insight into the optimal assembling of CNT network materials for elevated mechanical performance.
