Opis:: The report presents research efforts on the synthesis of Zn/MoS₂ composite coatings by electrochemical reduction from a sulphate-borate bath containing MoS₂ powder as a dispersion phase at various concentrations. The structure of the Zn/MoS₂ composite coatings was characterised and the effect of MoS₂ particles embedded on their microhardness was evaluated. The coatings produced are characterized by a compact, homogeneous structure and a good connection to a steel substrate. The incorporation of MoS₂ particles into the zinc matrix has an influence on the structure and morphology of the Zn/MoS₂ composite coatings. It was found that the presence of MoS₂ particles increases surface roughness along with coating hardness. The incorporation of the MoS₂ particles into the zinc matrix slightly improves the corrosion resistance compared to Zn coatings, making the corrosion potential shift towards more electropositive values.

Opis:: The electronic, optical and thermoelectric properties of MoS2 nano-sheet in presence of the ru impurity have been calculated by density functional theory framework with generalized gradient approximation. The MoRuS2 nano-sheet electronic structure was changed to the n-type semiconductor by 1.3 eV energy gap. The optical coefficients were shown that the loosing optical energy occurred in the higher ultraviolet region, so this compound is a promising candidate for optical sensing in the infrared and visible range. The thermoelectric behaviors were implied to the good merit parameter in the 100K range and room temperatures and also has high amount of power factor in 600K which made it for power generators applications.
