Dec 4, 2009 · The surface-modified IF nanoparticles display improved dispersion in oil-based suspensions. The alkyl-silane coating reduces the IF-WS 2 nanoparticles’ tendency to agglomerate and consequently improves the long-term …

In the present investigation, we report a one-step synthesis method of wafer-scale highly crystalline tungsten disulfide (WS 2) nanoparticle thin film by using a modified hot wire chemical vapor deposition (HW-CVD) technique. The average size of WS 2 nanoparticle is found to be 25–40 nm over an entire 4 in. wafer of quartz substrate.

Jul 13, 2023 · Multiwalled WS 2 and WSe 2 nanotubes with predominantly a single chiral angle are produced in a chemical vapour deposition reactor using gold nanoparticles as a catalyst.

Aug 15, 2014 · We report a successful fabrication of tungsten disulfide (WS2) nanostructures with different morphologies including rod-like, sheet-like and fiber-like ones via a simple yet facile hydrothermal process by adding surfactants cetyltrimethyl ammonium bromide (CTAB) and polyethylene glycol (PEG).

Dec 16, 2020 · Adding small amounts of inorganic nanoparticles of WS 2 have been shown to significantly improve the mechanical, tribological, thermal and rheological properties of various polymer and other materials.

Feb 1, 2019 · In the present study, a method was developed to prepare WS 2 and WS 2 /TiO 2 nanoparticles. In addition, the tribological properties of the as-synthesized WS 2 and WS 2 /TiO 2 nanoparticles were investigated in a base oil of diisooctyl sebacate (DOS).

Nanostructures of tungsten disulfide (WS 2) were discovered 25 years ago [1] and have been continuously studied ever since. WS 2 inorganic nanotubes (INTs) and fullerene-like nanoparticles (IFs) are closed cylindrical or polyhedral layered structures.

Sep 1, 2022 · Here, an interfacial engineering strategy to construct an efficient bifunctional electrocatalyst by in situ growing N-doped WS 2 nanoparticles on highly conductive cobalt nitride (N-WS 2 /Co 3 N) for concurrent hydrogen evolution reaction (HER) and urea oxidation reaction (UOR) is demonstrated.

Apr 27, 2017 · In this work, we have employed a hydrothermal route for the synthesis of fullerene-type tungsten disulfide (WS 2) nanoparticles. X-ray diffraction analysis signifies a hexagonal crystal structure of WS 2 with the crystallites experiencing preferred orientations along (002) and …

A unique new class of core–shell structured composite nanoparticles, C-coated inorganic fullerene-like WS 2 (IF-WS 2) hollow nanoparticles, has been created for the first time in large quantities, by a continuous chemical vapour deposition method using a rotary furnace.
