Optoelectronic properties of MoS2-ReS2 and ReS2-MoS2 heterostructures
Physica B: Condensed Matter, 2020Abstract We have investigated the electronic properties of heterostructures MoS2-ReS2 and ReS2-MoS2 with hybrid density functional theory. Contrary to the reported work, we found that ReS2 is an indirect band gap semiconductor material in the 2H phase, in good agreement with experimental work.

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.

Flexo-photovoltaic effect in MoS2
Nature Nanotechnology, 2021The theoretical Shockley-Queisser limit of photon-electricity conversion in a conventional p-n junction could be potentially overcome by the bulk photovoltaic effect that uniquely occurs in non-centrosymmetric materials. Using strain-gradient engineering, the flexo-photovoltaic effect, that is, the strain-gradient-induced bulk photovoltaic effect, can ...

We present a comprehensive analysis of a spaser made of a circular shaped highly doped molybdenum disulfide (MoS2) resonator. “Spaser” is an acronym for “surface plasmon amplification by stimulated emission of radiation”–a nanoscale source of surface plasmons generated by stimulated emission in a plasmonic resonator which receives energy nonradiatively.

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.

Tribology, 1969
The various physical and surface‐chemical factors which might affect the lubricating action of molybdenum disulphide are discussed; the importance of particle size and shape are emphasized. Up to date thoughts on lubrication mechanism are examined together with various environmental factors which can affect its industrial use. Recent Climax development

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 ...
