An overview of the recent advances in inorganic nanotubes

Abstract

Advanced nanomaterials and in particular nanotubes play a prominent role in nanoscience and nanotechnology developments, opening new frontiers in these areas.

The Role of Temperature on the Degree of End-Closing and Filling of Single-Walled Carbon Nanotubes

“…Having closed ends prevents leakage of the payload during the washing steps. Notably, during HRTEM analysis a single-layered inorganic nanotube of EuCl 3 was found inside the cavities of a large diameter DWCNT (see Supporting Information Figure S2b), thus creating a tubular (1 D) van der Waals heterostructure, as previously observed for other encapsulated 2D materials [50][51][52][53][54]. TEM imaging combined with EDX spectroscopy confirmed the presence of EuCl 3 in the internal cavity of the CNTs (Figure 4c).…”

Carbon Nanotubes: Smart Drug/Gene Delivery Carriers

“…The primary rationale behind nanotubular synthesis relies on the intrinsic instability of nascent 2D crystalline layered structures in the planar form. 135 Other nanotube structures that have been introduced are metal-organic framework (MOF) nanotubes, mono and mixed metal oxide nanotubes, and halloysite nanotubes. MOFs consist of organic-inorganic hybrid coordination networks in which the surface area, pore volume, pore size and their functionality can be tuned accurately.…”

Band structure of MoSTe Janus nanotubes

“…Furthermore, several TMDs have also been synthesized in a one-dimensional form as multiwalled nanotubes with diameters of several nanometers [8,9]. Such tubular structures are expected to have promising applications within a broad range of scientific areas such as, e.g., gas separation and capture, catalysis, solid lubrication, and controlled drug delivery [15], but so far advancements have been hampered by difficulties in producing single-wall nanotubes with a well-defined radius.…”
