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 ...

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 ...

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).

Molybdenum Disulfide — Amine Nanostructures

AIP Conference Proceedings, 2003
MoS2 with intercalated primary amines was synthesized and structurally characterized. The interlaminar distance of the MoS2 was found to increase from 0.6 nm to 5.1 nm for hexadecylamine. Hydrothermal treatment of these nanocomposites yields nanoparticles.

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 ...

Theoretical prediction of disulfide defects (S22−) in molybdenum disulfide monolayers

Journal of Molecular Modeling
Defects have a noticeable influence on many properties of two-dimensional materials. The controlled formation of defects can be used for fine-tuning the electronic and chemical properties of transition metal dichalcogenide monolayers. The formation of a new type of displacement defect on the molybdenum disulfide (MoS2) monolayer surface has been ...

Naphthalene intercalation into molybdenum disulfide

Chemical Communications, 1998
Exfoliation of LiMoS2 followed by reflocculation permits the intercalation of naphthalene guest molecules into the van der Waals gap of MoS2.
