Abstract: A method for preparing a carbon nanostructure including molybdenum disulfide is discussed. More particularly, a method is discussed for preparing a carbon nanostructure in which molybdenum disulfide is located on the surface by melt diffusion and heat treatment of a mixture of a molybdenum precursor, a carbon nanostructure, and sulfur. Also, a positive electrode of a lithium secondary battery including a carbon nanostructure including molybdenum disulfide as an additive, and a lithium secondary battery including the same. In the case of the lithium secondary battery including the positive electrode to which the carbon nanostructure including molybdenum disulfide was applied, the carbon nanostructure including the molybdenum disulfide adsorbs lithium polysulfide (LiPS) generated during the charging/discharging process of the lithium secondary battery, thereby increasing the charging/discharging efficiency of the battery and improving lifetime characteristics.

Abstract: Provided are a MoSxOy/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSxOy/carbon nanocomposite material, 2.5≤x≤3.1, 0.2≤y≤0.7, and the mass percent of MoSxOy is 5%-50% based on the total mass of the nanocomposite material. When the MoSxOy/carbon nanocomposite material is used as a catalyst for an electrocatalytic hydrogen evolution reaction, the current density is 150 mA/cm2 or more at an overpotential of 300 mV. The difference between this performance and the performance of a commercial 20% Pt/C catalyst is relatively small, or even equivalent; and this performance is far better than the catalytic performance of an existing MOS2 composite material. The MoSxOy/carbon nanocomposite material also has a good catalytic stability, and after 8,000 catalytic cycles, the current density thereof is only decreased by 3%, thus exhibiting a very good catalytic performance and cycle stability.

Abstract: A method of synthesis of two-dimensional (2D) nanoparticles comprises combining a first nanoparticle precursor and a second nanoparticle precursor in one or more solvents to form a solution, followed by heating the solution to a first temperature for a first time period, then subsequently heating the solution to a second temperature for a second time period, wherein the second temperature is higher than the first temperature, to effect the conversion of the nanoparticle precursors into 2D nanoparticles. In one embodiment, the first nanoparticle precursor is a metal-amine complex and the second nanoparticle precursor is a slow-releasing chalcogen source.

Abstract: Electronic-photonic integrated circuits (EPICs), such a monolithically integrated circuit, are considered to be next generation technology that takes advantage of high-speed optical communication and nanoscale electronics. Atomically thin transition metal dichalcogenides (TMDs) may serve as a perfect platform to realize EPIC. The generation and detection of light by a monolayer TMD at nanoscale through surface plasmon polaritons (SPPs) may be utilized to provide optical communication. The bidirectional nature of the TMDs allow such a layer to be utilizes as part of emitters or photodetectors for EPICs.

Abstract: Disclosed herein is a method for exfoliating a laminar material to form an exfoliated material, in which the laminar material is ultrasonicated in a solution of a surfactant for sufficient time to form the exfoliated material. At all times during the ultrasonication the concentration of the surfactant in the solution is maintained sufficient to form a complete monolayer on the surfaces of the laminar material and the exfoliated material in the solution, or sufficient to sterically stabilize the laminar and exfoliated materials against aggregation.
