“…[35] Moreover, the presence of the strongly scattering halogen (I, Z= 53) allows an easy differentiation of the grown structures by Z-contrast microscopy. [36,37] Actually the intensity profile across the main tube axis can also be employed to determine the thickness of the inner coating. HRTEM images of several encapsulated metal halides, namely ZnI2, CeI3 and TbI3 are presented in Figure 4 along with the bulk structural model of the employed layered materials.…”

The unique properties of two-dimensional (2D) nanomaterials make them highly attractive for a wide range of applications. As a consequence, several top-down and bottom up approaches are being explored to isolate or synthesize single-layers of 2D materials in a reliable manner. Here we report on the synthesis of individual layers of several 2D van der Waals solids, namely CeI3, CeCl3, TbCl3 and ZnI2 by templateassisted growth using carbon nanotubes as directing agents, thus proving the versatility of this approach. Once confined, the metal halides can adopt different structures including single-layered metal halide nanotubes, which formation is greatly enhanced by increasing the temperature of synthesis. This opens up a new strategy for the isolation of individual layers of a wide variety of metal halides, a family of 2D materials that has been barely explored.

“…Most of the works reported the [2 + 1] cycloaddition of dichlorocarbene (CCl2) on sidewalls of both SWCNTs [13,14] and BNNTs [15,16], whereas a few papers investigated carbenes addition on fullerenes [17] and graphene [18]. Thus, Luksirikul et al, using the high reactivity of carbenes, obtained functionalized SWCNTs with different substituents; the authors pointed out that they enhance dispersibility of such SWCNTs [19]. From this point of view, we can assume the CH2 functionalization of SWCNTs and BNNTs, owing to its simplicity, as a good starting point for a novel nanotube/polymer composite design.…”

This paper presents quantum chemistry study on structural and mechanical properties of a series of single-walled carbon nanotubes (SWCNTs) and boron nitride nanotubes (BNNTs) functionalized with carbenes. At the PBE/SVP level, the obtained data on pristine nanotubes are in good accordance with the results of previous experimental and theoretical studies. The calculations show that carbenes functionalization, in general, distorts both SWNCTs and BNNTs frameworks, but there exists the difference between 'axial' and 'circumferential' functionalization. It turns out that in both cases elastic properties diminish with increasing concentration of adsorbents, however, the functionalized SWCNTs and BNNTs remain strong enough to be suitable for reinforcement of composites.

Carbon nanotubes (CNTs) have emerged worldwide because of their remarkable properties enlarging their field of applications. Functionalization of CNTs is a convenient strategy to tackle low dispersion and solubilization of CNTs in many solvents or polymers. It can be done by covalent or noncovalent surface functionalization that is briefly discussed regarding the current literature. Endohedral and exohedral are conventional methods based on covalent and van der Waals bonding forces that are created through CNT functionalization by various materials. In this paper, a review of new approaches and mechanisms of functionalization of CNTs is proposed, including amidation, fluorination, bromination, chlorination, hydrogenation, and electrophilic addition. Our analysis is supported by several characterization methods highlighting recent improvements hence extending the range of applicability of CNTs.
