Scalable Fabrication of Molybdenum Disulfide Nanostructures and their Assembly

Advanced Materials, 2020
AbstractMolybdenum disulfide (MoS2) is a multifunctional material that can be used for various applications. In the single‐crystalline form, MoS2 shows superior electronic properties. It is also an exceptionally useful nanomaterial in its polycrystalline form with applications in catalysis, energy storage, water treatment, and gas sensing.

Pressure-Induced Metallization of Molybdenum Disulfide

Physical Review Letters, 2014
X-ray diffraction, Raman spectroscopy, and electrical conductivity measurements of molybdenum disulfide MoS(2) are performed at pressures up to 81 GPa in diamond anvil cells. Above 20 GPa, we find discontinuous changes in Raman spectra and x-ray diffraction patterns which provide evidence for isostructural phase transition from 2H(c) to 2H(a ...

Magnetic Molybdenum Disulfide Nanosheet Films

Nano Letters, 2007
Bulk molybdenum disulfide is known to be a nonmagnetic material. We have synthesized edge-oriented MoS2 nanosheet-like films that exhibit weak magnetism ( approximately 1-2 emu/g) and 2.5% magnetoresistance effects with a Curie temperature of 685 K.

Fracture mechanics of monolayer molybdenum disulfide

Nanotechnology, 2015
Molecular dynamics (MD) modeling is used to study the fracture toughness and crack propagation path of monolayer molybdenum disulfide (MoS(2)) sheets under mixed modes I and II loading. Sheets with both initial armchair and zigzag cracks are studied.

Phenanthroline intercalation into molybdenum disulfide

Solid State Ionics, 1996
Abstract The interaction of MoS 2 single-layer dispersion with 1,10-phenanthroline has been studied over the pH range 0–11. Only protonated phenanthroline initiates flocculation of dispersion and formation of intercalation compounds. Two intercalated phases containing respectively 0.31–0.35 and 0.1 mol of phenanthroline per mol MoS 2 have been ...

Optical Properties of Triangular Molybdenum Disulfide Nanoflakes

The Journal of Physical Chemistry Letters, 2014
The results from calculations of optical and electronic properties of triangular MoS2 nanoflakes with edge lengths ranging from 1.6 to 10.4 nm are presented. The optical spectra were calculated using the time-dependent extension of the density-functional tight-binding method (TD-DFTB).

Superconductivity in Intercalated Molybdenum Disulfide

AIP Conference Proceedings, 1972
X-ray studies show the existence of two different types of expansions of the intercalated unit cell in both Na and K compounds. Two different phases are also indicated in the superconducting behavior of the K compound. All intercalated samples studied show a superconducting transition. K and Rb compounds become superconductors in the temperature range

Intercalation of tetraazamacrocycles into molybdenum disulfide

J. Mater. Chem., 2003
A series of intercalation compounds of tetraazamacrocycles in molybdenum disulfide have been synthesized using the exfoliation and restacking properties of LiMoS2. The sandwiched compounds were characterized by powder X-ray diffraction, thermogravimetric analyses, differential scanning calorimetry, and four-probe electrical conductivity measurements ...

Superconductivity in Intercalated Molybdenum Disulfide

Physical Review Letters, 1971
Molybdenum disulfide has been intercalated with sodium and potassium. Both natural crystals of molybdenite and synthetic crystals were used, and measurements made on the intercalated products indicate a superconducting transition temperature of \ensuremath{\sim}1.3\ifmmode^\circ\else\textdegree\fi{}K for sodium and \ensuremath{\sim}4.5\ifmmode^\circ ...

Dispersions of molybdenum disulfide in oils

Chemistry and Technology of Fuels and Oils, 1990
medium; We have developed a gear oil with molybdenum disulfide. As the basic component, we chose PS-28 residual oil freed from medium-sulfur petroleum mixtures by solvent extraction. To improve the thermal oxidative stability, and also to increase the effectiveness of the solid additive's action, we added ester-2 (the reaction product of the ...
