MoS2(0001)/MoO3(010)/MoS2(0001) friction-reducing system
Wear, 2004Abstract A system of MoO 3 (0 1 0) nanocrystals confined between MoS 2 (0 0 0 1) surfaces is reported. MoO 3 (0 1 0) nanocrystals act as friction-reducing materials between MoS 2 (0 0 0 1) surfaces, where the frictional coefficient is an extremely small value of 0.005.

Abstract The water produced during the hydrodeoxygenation (HDO) processes has a negative effect on sulfide catalysts, which lowers the activity and stability. To solve this problem, hydrophobic MoS2, NiS2-MoS2 and CoS2-MoS2 catalysts are prepared and then applied into the HDO of 4-ethylphenol and 4-propylguaiacol.

Seeking effective methods to degrade organic pollutants has always been a hot research field. In this work, MoS2/Fe3O4 catalyst was synthesized by hydrothermal method with MoS2 as carrier to construct an advanced oxidation system of electrochemical enhanced MoS2/Fe3O4-activated peroxymonosulfate (E/MoS2/Fe3O4/PMS). The materials were characterized by X-

Abstract MoS 2 has been exfoliated into monolayers by intercalation with lithium followed by reaction with water. X-ray diffraction analysis has shown that the exfoliated MoS 2 in suspension is in the form of one-molecule-thick sheets. X-ray patterns from dried and re-stacked films of exfoliated MoS 2 indicate that the layers are randomly stacked.

High resolution electron microscopy of MoS2:Ni, MoS2:Co and MoS2:Fe layered crystals
Materials Letters, 1998Abstract High resolution electron microscopy (HREM) is a technique which allows one to get information which by other techniques is difficult to obtain, in particular, for diluted systems as for example, catalysts. It provides a direct way to measure the lattice parameters of the chemical phases that are present in the sample and can provide ...

We report on the existence of MoS2 hollowed microtubes, several mm in lengths and less than 0.1 μm wall thickness, grown from the vapor phase. Scanning electron microscopy studies reveal that instability of thin weakly bonded sheets against folding causes the tube growth directly or indirectly beyond the formation of turbulent gas flow.

Nonlinear optical modulation of MoS2/black phosphorus/MoS2 at 1550 nm
Physica B: Condensed Matter, 2020Abstract A sandwich structure of black phosphorus nanosheets coupled with MoS2 nanosheets was prepared via liquid exfoliation and hydrothermal methods. An enhancement of saturated absorption was observed at the long wavelength of 1550 nm via the femtosecond Z-scan technique, which is much stronger than its nonlinear response at 400 and 800 nm ...

Most publications on (opto)electronic devices based on 2D materials rely on single monolayers embedded in classical 3D semiconductors, dielectrics and metals. However, heterostructures of different 2D materials can be employed to tailor the performance of the 2D components by reduced defect densities, carrier or exciton transfer processes and improved ...
