Bundle of Nanobelts Up to 4 cm in Length: One‐Step Synthesis and Preparation of Titanium Trisulfide (TiS₃) Nanomaterials

Abstract

One-dimensional (1D) titanium trisulfide (TiS 3 ) nanobelt bundles up to 4 cm in length have been successfully synthesized through an easy and common chemical vapor transition (CVT) process. The as-synthesized samples were characterized by X-ray powder diffraction (XRD), polarized light microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). All microscopic observations indicated a belt-like morphology. Powder XRD patterns showed that TiS 3 crystallized in the monoclinic system with a = 4.958(1) Å, b = 3.393(1) Å, c = 8.793(3) Å and β = 97.27(5)°. TEM images revealed a nanostructure with an interplanar spacing of 0.87 nm. The ED pattern and HRTEM images con-

Synthesis, Crystal Structure, and Colloidal Dispersions of Vanadium Tetrasulfide (VS4)

“…The rodlike morphology of the VS 4 particles implies that the bulk is preferentially defragmented by separation of weakly bonded chains 2k. However, the rods deposited from dispersion are not only narrower but also much shorter than in the parent bulk.…”

Distinct Element Method Modeling of Carbon Nanotube Bundles With Intertube Sliding and Dissipation

“…The DEM model applied here to model bundles of CNTs can be generalized to model other classes of nanostructures with similar properties, such as bundles of nanowires (nanobelts) and organic fibers and fibrous biological tissues [36,38,39]. The DEM model presented here is able to describe in a "hands-off" manner the extensive plastic change in response to small stress caused by the sliding of individual CNTs across each other.…”

TiS3 Transistors with Tailored Morphology and Electrical Properties

“…[10][11][12][13] In particular, TiS 3 , having a direct optical band gap of ≈1 eV and ultrahigh optical responsivities (≈3000 A W −1 ), shows promise as a suitable replacement to microstructured silicon in applications where high gain is required. [ 16,17 ] Here, we demonstrate control over the morphology of TiS 3 to obtain nanosheets with large surface area that facilitates the exfoliation of TiS 3 down to a single layer (≈0.9 nm thick).
